Android Studio v1.1/1.2中的渲染问题

小开

最佳答案

I don't know if this will help or not, but I was creating a test project (direct from the wizard, no custom code) and getting this error. Trying to modify the project structure and find the missing class didn't help.

The build failed with the following error:

***rendering problems

The following classes could not be found android.support.v7.internal.widget.ActionBarOverlayLayout***

Obviously it's not the final solution, but changing the Theme in design view from the base "project theme" to anything else allows it to build.

UPDATE: Apparently they have fixed this bug in the final Android Studio 1.3 release (according to users reporting this issue solved in the issue tracker: https://issuetracker.google.com/issues/37043358).

This is a known bug since Android Studio build 1.1, which still exists in AS versions 1.2 and 1.3 beta. Switching the preview's API level from 22 to 21 fixes the for most people. While waiting for a fix you could try it as well.

Android Studio Layout Preview - Switch API to 21

UPDATE: This is already reported as a known issue of Android Studio (http://tools.android.com/knownissues#TOC-Can-t-Render-Layouts-in-Android-Studio-1.2)

I changed the AppTheme above the graphical preview to Base.Theme.AppCompat and it disappeared for me. It worked on both 19 and 22 API :) ! Good Luck to all of you!

Possible solutions that worked for me:

1 -> Add the word Base. to the beginning of the theme name so that it reads "Base.Theme.AppCompat.Light.DarkActionBar"

i.e., Change AppTheme parent in res/values/styles.xml to resolve this problem. Replace

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
</style>

with

<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
</style>

OR

2- > Downgrade API level from 22 to 21 in preview pane as suggested by @david.schreiber

Adding to david.schreiber's answer, if you keep your preview in a tight window you may wanna stretch it to access that Android icon.

I changed my app theme from "Theme.AppCompat.Light.DarkActionBar" to "Base.Theme.AppCompat.Light.DarkActionBar"

I encountered this problem just now in Android Studio 1.2.1.0 with API 22 (Android 5.1.1) selected without changing the theme or API as suggested by others on this thread.

When I updated to the most recent version of Android Studio available via the regular update check, it works fine now. This shouldn't be a problem in the new version Android Studio 1.2.1.1

Changing app theme to Base.Theme.App.Compat worked for me.

I'm using Android Studio 1.2 as stable version and I have the same problem.

For me the solution was to use the Canary Channel and update Android Studio to 1.3.

Now I have this version and it works perfect but this is not and stable version

My build.grade is this

apply plugin: 'com.android.application'

android {
compileSdkVersion 22
buildToolsVersion '21.1.2'


defaultConfig {
applicationId "com.androidtest.materialdesign"
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}


dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.0'
}
