Rendering problems in Android Studio v 1.1 / 1.2 –

Development issue/problem:

When I add an android.support.v7.widget.Toolbar or another android.support.v7.widget.*, there are problems with the display.

However, the support library has been updated. And I obeyed my next of kin. I can import them into MainActivity.java.

What’s the problem?

How can I solve this problem?

Solution 1:

I don’t know if this helps or not, but I made a test project (straight from the wizard, no custom code) and I got this error. Trying to change the structure of the project and find the missing class didn’t help.

The construction failed with the following error:

***Most of the money laundering problems have been solved.

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

Of course, this is not the final solution, but changing the design theme from one basic project theme to another will build it.

Solution 2:

UPDATE: Apparently this bug has been fixed in the final version of Android Studio 1.3 (according to users who reported it in the issue tracker: https://issuetracker.google.com/issues/37043358).

This is a bug that has been known since the days of building Android Studio 1.1, and is still present in the 1.2 and 1.3 beta versions of the AS. Changing the preview API level from 22 to 21 solves the bug for most people. While we wait for a solution, we might as well try.

UPDATE: An important release of Android Studio (http://tools.android.com/knownissues#TOC-Can-t-Render-Layouts-in-Android-Studio-1.2) has already pointed this out.

Solution 3:

Possible solutions that worked for me:

1 -> At the beginning of the theme name, add the word Base.Theme.AppCompat.Light.DarkActionBar.

i.e. change the App Theme parent to res/values/styles.xml to solve this problem.
Replace

с

OR

2- > Lower the API level in the preview window from 22 to 21 as recommended by @david.schreiber.

Solution 4:

I changed the AppTheme above the graphical preview to Base.Theme.AppCompat and it’s gone. It worked for 19 and 22 PLC’s! Good luck to all of you!

Solution No 5:

I changed the theme of my application from Theme.AppCompat.Light.DarkActionBar to Base.Theme.AppCompat.Light.DarkActionBar.

Solution No 6:

I just came across this problem in Android Studio 1.2.1.0 with selected API 22 (Android 5.1.1), without changing the theme or API as others in this thread suggest.

When I updated the latest version of Android Studio, which is available through regular update checks, version
now works perfectly. With the new version of Android Studio 1.2.1.1 this shouldn’t be a problem.

Solution No 7:

Changing the Android version from 22 to 21, problem solved, it is the small Android icon in the upper right corner,

Solution No 8:

Added to david.schreiber’s answer: If you keep the preview in a narrow window, you need to broaden it to access the Android icon.

Solution No 9:

I use Android Studio 1.2 as a stable version and I have the same problem.

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

I have this version now and it works perfectly, but it’s not a stable version.

My Physical Rating

defaultConfig {applicationId com.androidtest.material designminSdkVersion 15targetSdkVersion 22versionCode 1versionName 1.0} Terms{release{releaseminifyEnabled falseproguardFiles getDefaultProguardFile(‘proguard-android.txt’), ‘proguard-rules.pro’}}}}}

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

Solution No 10:

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

Good luck!
