I'm trying to stream a video to a custom TextureView. The Video is shown in fullscreen mode. The layout is the same for portrait mode and landscape mode:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/root_layout"
tools:context=".SampleActivity">
<com.my.package.MyCustomTextureView
android:id="@+id/texture_custom"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:keepScreenOn="true" />
...
</RelativeLayout>
The Activity in the Manifest is set to handle the orientation changes itself:
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".SampleActivity"
android:configChanges="orientation|keyboardHidden|screenSize"
android:label="@string/app_name"
android:theme="@style/FullscreenTheme" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
When the orientation changes, the Activity seems to find the correct size:
public class SampleActivity extends FragmentActivity {
....
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
RelativeLayout root = (RelativeLayout) findViewById(R.id.root_layout);
MyCustomTextureView view = (MyCustomTextureView) findViewById(R.id.texture_custom);
Log.d(TAG, "onConfigurationChanged newConfig: " + newConfig.screenWidthDp + "x" + newConfig.screenHeightDp + " root: "+root.getWidth() + "x" + root.getHeight() + " view: " + view.getWidth() + "x" + view.getHeight());
....
}
}
Activity log output, when I pass from portrait to landscape (note: this is before the layout change):
09-29 15:30:28.975 22303-22303/com.my.package D/com.my.package.SampleActivity onConfigurationChanged newConfig: 598x335 root: 1080x1920 view: 1080x1920
...but the Custom Texture View is receiving the wrong values:
public class MyCustomTextureView extends TextureView implements TextureView.SurfaceTextureListener {
....
@Override
public void onSurfaceTextureSizeChanged(SurfaceTexture surfaceTexture, int width, int height) {
Log.v(TAG, "onSurfaceTextureSizeChanged params: " + width + "x" + height + ", old values " + mMyWidth + "x" + mMyHeight + ", method values: " + getWidth() + "x" + getHeight());
}
....
}
TextureView log output, when I pass from portrait to landscape:
09-29 15:30:29.037 22303-22303/com.my.package V/com.my.package.MyCustomTextureView﹕ onSurfaceTextureSizeChanged params: 1080x1080, old values 1080x1920, method values: 1080x1080
If I go back to portrait mode, it seems to retrieve the correct size once again:
Activity:
09-29 15:30:45.019 22303-22303/com.my.package D/com.my.package.SampleActivity onConfigurationChanged newConfig: 360x567 layout: 1920x1080 view: 1080x1080
TextureView:
09-29 15:30:45.096 22303-22303/com.my.package V/com.my.package.MyCustomTextureView onSurfaceTextureSizeChanged params: 1080x1920, old values 1080x1920, method values: 1080x1920
What am I doing wrong?
...ok, I found the solution myself, by intensive trial and error. Mostly error.
Anyway, I still have no idea why is it having this behaviour. If you have any idea, feel free to comment and enlighten me :D (and help anyone else that might have a similar problem).
The Idea came to me after reading Mark G.'s question. I simply added a line to the onConfigurationChanged function:
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
RelativeLayout root = (RelativeLayout) findViewById(R.id.root_layout);
MyCustomTextureView myView = (MyCustomTextureView) findViewById(R.id.texture_custom);
Log.d(TAG, "onConfigurationChanged newConfig: " + newConfig.screenWidthDp + "x" + newConfig.screenHeightDp + " root: "+root.getWidth() + "x" + root.getHeight() + " view: " + myView.getWidth() + "x" + myView.getHeight());
myView.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT));
....
}
With this change, when I pass from 1080x1920 to 1920x1080, I get the correct values in the onSurfaceTextureSizeChanged function, instead of 1080x1080. Same thing when I pass from 1920x1080 to 1080x1920.
...no, don't ask me why do I have to put this manually. I have no idea.
For the sake of being completely sure, I tried to put that line directly in the onSurfaceTextureSizeChanged function, instead of in onConfigurationChanged :
@Override
public void onSurfaceTextureSizeChanged(SurfaceTexture surfaceTexture, int width, int height) {
Log.v(TAG, "onSurfaceTextureSizeChanged params: " + width + "x" + height + ", old values " + mMyWidth + "x" + mMyHeight + ", method values: " + getWidth() + "x" + getHeight());
setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT));
}
...that didn't work. Once again, I ave no idea why. It MIGHT be because 1080x1080 is not the erroneous size of the TextureView, but the erroneous size of the root RelativeLayout itself.
