如何使用“共享图像使用”共享意图共享图像在安卓？

我有图像厨房应用程序在那个应用程序，我把所有的图像到绘制-hdpi 文件夹。 在我的活动中，我把图像称为:

private Integer[] imageIDs = {
R.drawable.wall1, R.drawable.wall2,
R.drawable.wall3, R.drawable.wall4,
R.drawable.wall5, R.drawable.wall6,
R.drawable.wall7, R.drawable.wall8,
R.drawable.wall9, R.drawable.wall10
};

所以现在我想知道如何使用分享意图来分享这些图片，我把分享代码放在这里:

     Button shareButton = (Button) findViewById(R.id.share_button);
shareButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
       

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse(Images.Media.EXTERNAL_CONTENT_URI + "/" + imageIDs);


sharingIntent.setType("image/jpeg");
sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
startActivity(Intent.createChooser(sharingIntent, "Share image using"));
    

}
});

当我点击分享按钮时，我也有分享按钮，分享框打开了 但是当我点击任何服务，大多数情况下，它的崩溃或一些服务说: 无法打开图像 所以我怎么才能解决这个问题，或者有没有其他的格式代码来共享图片? ? ？

编辑:

我尝试使用下面的代码，但是不起作用。

Button shareButton = (Button) findViewById(R.id.share_button);
shareButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {


Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse("android.resource://com.android.test/*");
try {
InputStream stream = getContentResolver().openInputStream(screenshotUri);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
sharingIntent.setType("image/jpeg");
sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
startActivity(Intent.createChooser(sharingIntent, "Share image using"));


}
});

如果不介意有人请纠正我的上述代码或给我一个适当的例子请如何分享我的图像从绘制-hdpi 文件夹

The solution proposed from superM worked for me for a long time, but lately I tested it on 4.2 (HTC One) and it stopped working there. I am aware that this is a workaround, but it was the only one which worked for me with all devices and versions.

According to the documentation, developers are asked to "use the system MediaStore" to send binary content. This, however, has the (dis-)advantage, that the media content will be saved permanently on the device.

If this is an option for you, you might want to grant permission WRITE_EXTERNAL_STORAGE and use the system-wide MediaStore.

Bitmap icon = mBitmap;
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");


ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, "title");
values.put(Images.Media.MIME_TYPE, "image/jpeg");
Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI,
values);




OutputStream outstream;
try {
outstream = getContentResolver().openOutputStream(uri);
icon.compress(Bitmap.CompressFormat.JPEG, 100, outstream);
outstream.close();
} catch (Exception e) {
System.err.println(e.toString());
}


share.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(share, "Share Image"));

Here is a solution that worked for me. One gotcha is you need to store the images in a shared or non app private location (http://developer.android.com/guide/topics/data/data-storage.html#InternalCache)

Many suggestions say to store in the Apps "private" cache location but this of course is not accessable via other external applications, including the generic Share File intent which is being utilised. When you try this, it will run but for example dropbox will tell you the file is no longer available.

/* STEP 1 - Save bitmap file locally using file save function below. */

localAbsoluteFilePath = saveImageLocally(bitmapImage);

/* STEP 2 - Share the non private Absolute file path to the share file intent */

if (localAbsoluteFilePath!=null && localAbsoluteFilePath!="") {


Intent shareIntent = new Intent(Intent.ACTION_SEND);
Uri phototUri = Uri.parse(localAbsoluteFilePath);


File file = new File(phototUri.getPath());


Log.d(TAG, "file path: " +file.getPath());


if(file.exists()) {
// file create success


} else {
// file create fail
}
shareIntent.setData(phototUri);
shareIntent.setType("image/png");
shareIntent.putExtra(Intent.EXTRA_STREAM, phototUri);
activity.startActivityForResult(Intent.createChooser(shareIntent, "Share Via"), Navigator.REQUEST_SHARE_ACTION);
}

/* SAVE IMAGE FUNCTION */

    private String saveImageLocally(Bitmap _bitmap) {


File outputDir = Utils.getAlbumStorageDir(Environment.DIRECTORY_DOWNLOADS);
File outputFile = null;
try {
outputFile = File.createTempFile("tmp", ".png", outputDir);
} catch (IOException e1) {
// handle exception
}


try {
FileOutputStream out = new FileOutputStream(outputFile);
_bitmap.compress(Bitmap.CompressFormat.PNG, 90, out);
out.close();


} catch (Exception e) {
// handle exception
}


return outputFile.getAbsolutePath();
}

/* STEP 3 - Handle Share File Intent result. Need to remote temporary file etc. */

    @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);


// deal with this with whatever constant you use. i have a navigator object to handle my navigation so it also holds all mys constants for intents
if (requestCode== Navigator.REQUEST_SHARE_ACTION) {
// delete temp file
File file = new File (localAbsoluteFilePath);
file.delete();


Toaster toast = new Toaster(activity);
toast.popBurntToast("Successfully shared");
}




}

I hope that helps someone.

First add permission

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

using Bitmap from resources

Bitmap b =BitmapFactory.decodeResource(getResources(),R.drawable.userimage);
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
b.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(getContentResolver(), b, "Title", null);
Uri imageUri =  Uri.parse(path);
share.putExtra(Intent.EXTRA_STREAM, imageUri);
startActivity(Intent.createChooser(share, "Select"));

Tested via bluetooth and other messengers

SuperM answer worked for me but with Uri.fromFile() instead of Uri.parse().

With Uri.parse(), it worked only with Whatsapp.

This is my code: 

sharingIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(mFile));

Output of Uri.parse():
/storage/emulated/0/Android/data/application_package/Files/17072015_0927.jpg

Output of Uri.fromFile:
file:///storage/emulated/0/Android/data/application_package/Files/17072015_0927.jpg

I just had the same problem.
Here is an answer that doesn't use any explicit file writing in your main code (letting the api taking care of it for you).

Drawable mDrawable = myImageView1.getDrawable();
Bitmap mBitmap = ((BitmapDrawable)mDrawable).getBitmap();
String path = MediaStore.Images.Media.insertImage(getContentResolver(), mBitmap, "Image I want to share", null);
Uri uri = Uri.parse(path);
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
shareIntent.setType("image/*");
startActivity(Intent.createChooser(shareIntent, "Share Image"));

This is the path... you just need to add your image IDs in a Drawable object. In my case (code above), the drawable was extracted from an ImageView.

小开

I found the easiest way to do this is by using the MediaStore to temporarily store the image that you want to share:

Drawable mDrawable = mImageView.getDrawable();
Bitmap mBitmap = ((BitmapDrawable) mDrawable).getBitmap();


String path = MediaStore.Images.Media.insertImage(getContentResolver(), mBitmap, "Image Description", null);
Uri uri = Uri.parse(path);


Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/jpeg");
intent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(intent, "Share Image"));

Simple and Easiest code you can use it to share image from gallery.

 String image_path;
File file = new File(image_path);
Uri uri = Uri.fromFile(file);
Intent intent = new Intent(Intent.ACTION_SEND);
intent .setType("image/*");
intent .putExtra(Intent.EXTRA_STREAM, uri);
context.startActivity(intent );

I was tired in Searching different options for sharing view or image from my application to other application . And finally i got the solution.

Step 1 : Share Intent handling Block. This will Pop Up your window with list of Applications in you phone

public void share_bitMap_to_Apps() {


Intent i = new Intent(Intent.ACTION_SEND);


i.setType("image/*");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
/*compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] bytes = stream.toByteArray();*/




i.putExtra(Intent.EXTRA_STREAM, getImageUri(mContext, getBitmapFromView(relative_me_other)));
try {
startActivity(Intent.createChooser(i, "My Profile ..."));
} catch (android.content.ActivityNotFoundException ex) {


ex.printStackTrace();
}




}

Step 2 : Converting your view to BItmap

public static Bitmap getBitmapFromView(View view) {
//Define a bitmap with the same size as the view
Bitmap returnedBitmap = Bitmap.createBitmap(view.getWidth(),      view.getHeight(), Bitmap.Config.ARGB_8888);
//Bind a canvas to it
Canvas canvas = new Canvas(returnedBitmap);
//Get the view's background
Drawable bgDrawable = view.getBackground();
if (bgDrawable != null)
//has background drawable, then draw it on the canvas
bgDrawable.draw(canvas);
else
//does not have background drawable, then draw white background on the canvas
canvas.drawColor(Color.WHITE);
// draw the view on the canvas
view.draw(canvas);
//return the bitmap
return returnedBitmap;
}

Step 3 :

To get The URI from Bitmap Image

public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);


String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}

How to share image in android progamatically , Sometimes you wants to take a snapshot of your view and then like to share it so follow these steps: 1.Add permission to mainfest file 

<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

2.Very First take a screenshot of your view , for example it is Imageview, Textview, Framelayout,LinearLayout etc

For example you have an image view to take screenshot call this method in oncreate() 

 ImageView image= (ImageView)findViewById(R.id.iv_answer_circle);
///take a creenshot
screenShot(image);

after taking screenshot call share image method either on button
click or where you wants

shareBitmap(screenShot(image),"myimage");

After on create method define these two method ##

    public Bitmap screenShot(View view) {
Bitmap bitmap = Bitmap.createBitmap(view.getWidth(),
view.getHeight(), Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
view.draw(canvas);
return bitmap;
}


//////// this method share your image
private void shareBitmap (Bitmap bitmap,String fileName) {
try {
File file = new File(getContext().getCacheDir(), fileName + ".png");
FileOutputStream fOut = new FileOutputStream(file);
bitmap.compress(CompressFormat.PNG, 100, fOut);
fOut.flush();
fOut.close();
file.setReadable(true, false);
final Intent intent = new Intent(     android.content.Intent.ACTION_SEND);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
intent.setType("image/png");
startActivity(intent);
} catch (Exception e) {
e.printStackTrace();
}


}

A perfect solution for share text and Image via Intent is :

On your share button click :

Bitmap image;
shareimagebutton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {


URL url = null;
try {
url = new URL("https://firebasestorage.googleapis.com/v0/b/fir-notificationdemo-dbefb.appspot.com/o/abc_text_select_handle_middle_mtrl_light.png?alt=media&token=c624ab1b-f840-479e-9e0d-6fe8142478e8");
image = BitmapFactory.decodeStream(url.openConnection().getInputStream());
} catch (IOException e) {
e.printStackTrace();
}
shareBitmap(image);
}
});

Then Create shareBitmap(image) method.

private void shareBitmap(Bitmap bitmap) {


final String shareText = getString(R.string.share_text) + " "
+ getString(R.string.app_name) + " developed by "
+ "https://play.google.com/store/apps/details?id=" + getPackageName() + ": \n\n";


try {
File file = new File(this.getExternalCacheDir(), "share.png");
FileOutputStream fOut = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, fOut);
fOut.flush();
fOut.close();
file.setReadable(true, false);
final Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(Intent.EXTRA_TEXT, shareText);
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
intent.setType("image/png");
startActivity(Intent.createChooser(intent, "Share image via"));


} catch (Exception e) {
e.printStackTrace();
}


}

And then just test It..!!

All the Above solution doesnot work for me in Android Api 26 & 27 (Oreo), was gettting Error: exposed beyond app through ClipData.Item.getUri. The solution that fits in my situation was

  1. get path uri using FileProvider.getUriForFile(Context,packagename,File) as 
void shareImage() {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM, FileProvider.getUriForFile(this,getPackageName(),deleteFilePath));
startActivity(Intent.createChooser(intent,"Share with..."));
}
  1. Define a <provider> in your Manifest.xml as
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.example.stickerapplication"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths">
</meta-data>
</provider>
  1. And the last step is to define resource file for your directorys
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="." />
</paths>

*Note this solution is for `external storage` `uri`

With implementation of stricter security policies, exposing uri outside of app throws an error and application crashes.

@Ali Tamoor's answer explains using File Providers, this is the recommended way.

For more details see - https://developer.android.com/training/secure-file-sharing/setup-sharing

Also you need to include androidx core library to your project.

implementation "androidx.core:core:1.2.0"

Of course this is bit bulky library and need it just for sharing files -- if there is a better way please let me know.

Thanks all, I tried the few of the options given, but those seems not to work for the latest android releases, so adding the modified steps which work for the latest android releases. these are based on few of the answers above but with modifications & the solution is based on the use of File Provider :

Step:1

Add Following code in Manifest File:

<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_provider_paths" />
</provider>

step:2 Create an XML File in res > xml

Create file_provider_paths file inside xml.

Note that this is the file which we include in the android:resource in the previous step.

Write following codes inside the file_provider_paths:

<?xml version="1.0" encoding="utf-8"?>
<paths>
<cache-path name="cache" path="/" />
<files-path name="files" path="/" />
</paths>

Step:3

After that go to your button Click:

Button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {


Bitmap bit = BitmapFactory.decodeResource(context.getResources(),  R.drawable.filename);
File filesDir = context.getApplicationContext().getFilesDir();
File imageFile = new File(filesDir, "birds.png");
OutputStream os;
try {
os = new FileOutputStream(imageFile);
bit.compress(Bitmap.CompressFormat.PNG, 100, os);
os.flush();
os.close();
} catch (Exception e) {
Log.e(getClass().getSimpleName(), "Error writing bitmap", e);
}


Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);


Uri imageUri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID, imageFile);


intent.putExtra(Intent.EXTRA_STREAM, imageUri);
intent.setType("image/*");
context.startActivity(intent);
}
});
