Question

我已经在项目中实现了Twilio Programmable Video Call。通话连接后，我需要支持“画中画”模式。

我添加了一个具有固定高度和宽度的视图以显示本地视频。我单击一个按钮以在PIP模式下进入活动。固定视图也会在PIP模式下调整大小，但是几秒钟后，固定视图会展开。

清单-

       <activity
        android:name=".call.TwilioVideoCallActivity"    
        android:configChanges="screenSize|smallestScreenSize|screenLayout|orientation"
        android:launchMode="singleTask"
        android:screenOrientation="portrait"
        android:resizeableActivity="true"
        android:supportsPictureInPicture="true"
        android:excludeFromRecents="true"
        />

输入画中画模式-

@Override
public void onPictureInPictureModeChanged(boolean isInPictureInPictureMode, Configuration newConfig) {
    super.onPictureInPictureModeChanged(isInPictureInPictureMode, newConfig);
    if (!isInPictureInPictureMode) {

        showControllers();
    }
    this.inPictureInPictureMode = isInPictureInPictureMode;
}

private boolean isPIPSupport() {
    PackageManager packageManager = getApplicationContext().getPackageManager();

    return packageManager.hasSystemFeature(PackageManager.FEATURE_PICTURE_IN_PICTURE) && canEnterPiPMode(getApplicationContext());
}

public static boolean canEnterPiPMode(Context context) {
    AppOpsManager appOpsManager = null;
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
        appOpsManager = (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE);
        return (AppOpsManager.MODE_ALLOWED == appOpsManager.checkOpNoThrow(AppOpsManager.OPSTR_PICTURE_IN_PICTURE, android.os.Process.myUid(), context.getPackageName()));

    }
    return false;
}

private void hideControllers() {
    footerLyt.setVisibility(View.GONE);
    callEndBtn.setVisibility(View.GONE);

    minimizeBtn.setVisibility(View.GONE);
    timeChronometer.setVisibility(View.GONE);


}

private void showControllers() {
    footerLyt.setVisibility(View.VISIBLE);
    callEndBtn.setVisibility(View.VISIBLE);

    minimizeBtn.setVisibility(View.VISIBLE);
    timeChronometer.setVisibility(View.VISIBLE);


}

private void minimize() {

    // Hide the controls in picture-in-picture mode.

    // Calculate the aspect ratio of the PIP screen.
    hideControllers();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        Rational aspectRatio = new Rational(
                3, 4);
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            PictureInPictureParams params = new PictureInPictureParams.Builder()
                    .setAspectRatio(aspectRatio)
                    .build();
            enterPictureInPictureMode(params);
        } else {
            enterPictureInPictureMode();
        }

    }
}


@Override
public void onUserLeaveHint() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N && isCallConnected && isPIPSupport()) {
        if (!isInPictureInPictureMode()) {
            minimize();
        }
    }
}

画中画模式->进入点子模式后展开子视图
