定向完成后的Android运行方法



我有一些代码将在方向更改时运行:

@Override
public void onConfigurationChanged(Configuration newConfig){
    super.onConfigurationChanged(newConfig);
    setVideoSize();
    _videoSurfaceView.changeCameraDisplaySize();
}
private void setVideoSize() {
    //Get the dimensions of the video
    int videoWidth = _videoSurfaceView.getCamera().getParameters().getPreferredPreviewSizeForVideo().width;
    int videoHeight = _videoSurfaceView.getCamera().getParameters().getPreferredPreviewSizeForVideo().height;
    float videoProportion = (float) videoWidth / (float) videoHeight;
    // Get the width of the screen
    int screenWidth = getWindowManager().getDefaultDisplay().getWidth();
    int screenHeight = getWindowManager().getDefaultDisplay().getHeight();
    float screenProportion = (float) screenWidth / (float) screenHeight;
    // Get the SurfaceView layout parameters
    android.view.ViewGroup.LayoutParams lp = _videoSurfaceView.getLayoutParams();
    if (videoProportion > screenProportion) {
        lp.width = screenWidth;
        lp.height = (int) ((float) screenWidth / videoProportion);
    } else {
        lp.width = (int) (videoProportion * (float) screenHeight);
        lp.height = screenHeight;
    }
    // Commit the layout parameters
    _videoSurfaceView.setLayoutParams(lp);
}

这是在发生旋转时调用的,但我需要在旋转完成后运行setVideoSize()。有办法做到这一点吗?

请尝试在onResume()中运行您的方法。当活动从暂停状态恢复时调用。

请注意,当您更改方向活动时,会重新创建onResume()
