Exception raised during rendering: Unable to locate mode 0

问题

After update BuildTools to version 25.0.0.

compileSdkVersion 25
buildToolsVersion "25"

I have problem with android layout preview. Now it show error:

Exception raised during rendering: Unable to locate mode 0

I tried to Clean & Rebuild project, but it doesn't work. Before update everything was good.

I know that I can go back to previous versions of BuildTools, but I want to know why it doesn't work on version 25.0.0?

Seems like it is a problem with RecyclerView

回答1:

This issue has been resolved, update the support library to

compile 'com.android.support:recyclerview-v7:25.0.1'
compile 'com.android.support:appcompat-v7:25.0.1'
compile 'com.android.support:design:25.0.1'

回答2:

It's an Annoying bug of version 25.. A Temporary solution is to downgrade your project,

 compile 'com.android.support:appcompat-v7:24.2.1'
 compile 'com.android.support:design:24.2.1'
 compile 'com.android.support:recyclerview-v7:24.2.1'

回答3:

Another temporary solution is to replace <android.support.v7.widget.RecyclerView with <RecyclerView so you can see the rendered View. When compiling, change it back to <android.support.v7.widget.RecyclerView

回答4:

The Android Support Library provides backward-compatible utility functions. Apps can use these utility functions to provide an appropriate user experience across a wide range of Android system versions.

It's a bug issue and should be fixed in the future Release of the support-design library.

• Rendering Problems - Exception raised during rendering: Unable to locate mode 0

You should downgrade your version for Temporary Solutions .

compile 'com.android.support:appcompat-v7:25.0.1'
compile 'com.android.support:design:v7:25.0.1' 
compile 'com.android.support:recyclerview-v7:25.0.1' 

回答5:

To see preview I use this trick..... add app:layoutManager="0" for the recyclerView in a layout XML

But it will throw InflateException at run time. So REMOVE this property from XML layout file before running the app!

回答6:

As temp solution you can create child class of recycler view and override only onAttachedToWindow as below. Then use this class in your XML layouts

@Override
protected void onAttachedToWindow() {
    if (!isInEditMode()) {
        super.onAttachedToWindow();
    }
}

Update: starting from support library 25.0.1, fix already included in the library and issue not exist anymore
