Android AlertDialog 单按钮

我希望有一个 AlertDialog 构建器，只有一个按钮说 OK 或完成或东西，而不是默认的是和否。 这是否可以通过标准的 AlertDialog 来实现，还是需要使用其他工具？

最佳答案

不能只用一个正面按钮吗？

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Look at this dialog!")
.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//do things
}
});
AlertDialog alert = builder.create();
alert.show();

你可以用这个:

AlertDialog.Builder builder1 = new AlertDialog.Builder(this);
builder1.setTitle("Title");
builder1.setMessage("my message");
builder1.setCancelable(true);
builder1.setNeutralButton(android.R.string.ok,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});


AlertDialog alert11 = builder1.create();
alert11.show();

在 Mono for Android 中，你可以这样做:

var ad = new AlertDialog.Builder(this);
ad.SetTitle("Title");
ad.SetMessage("Message");
ad.SetPositiveButton("OK", delegate { ad.Dispose(); });
ad.Show();

为了代码重用，您可以使用这样的方法

public static Dialog getDialog(Context context,String title, String message, DialogType typeButtons ) {


AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle(title)
.setMessage(message)
.setCancelable(false);


if (typeButtons == DialogType.SINGLE_BUTTON) {
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//do things
}
});
}


AlertDialog alert = builder.create();


return alert;
}


public enum DialogType {
SINGLE_BUTTON


}

//其他代码重用问题，如使用接口提供反馈，也将是非常好的。

另一种方法

Builder alert = new AlertDialog.Builder(ActivityName.this);
alert.setTitle("Doctor");
alert.setMessage("message");
alert.setPositiveButton("OK",null);
alert.show();

额外奖励

AlertDialog.Builder builder = new AlertDialog.Builder(YourActivityName.this);
builder.setMessage("Message dialog with three buttons");


builder.setPositiveButton("YES", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//do things
}
});


builder.setNegativeButton("NO", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//do things
}
});


builder.setNeutralButton("CANCEL", new DialogInterface.OnClickListener()     {
public void onClick(DialogInterface dialog, int id) {
//do things
}
});
AlertDialog alert = builder.create();
alert.show();

现在你可以用一个，两个或三个按钮. 。

如果 Android API 足够聪明的话，这就是我能找到的最接近一行的代码了:

new AlertDialog.Builder(this)
.setMessage(msg)
.setPositiveButton("OK", null)
.show();

很简单

new AlertDialog.Builder(this).setView(input).setPositiveButton("ENTER",
new DialogInterface.OnClickListener()
{   public void onClick(DialogInterface di,int id)
{
output.setText(input.getText().toString());
}
}
)
.create().show();
