Android上运行的方法是完全

Question

我有一些代码，运行时orientation changes：

@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); 
} 

当发生旋转时这就是所谓的，但我需要运行setVideoSize（）转动完成后，。有没有办法做到这一点？

请尝试在onResume()中运行您的方法。从暂停状态恢复活动时调用。

请注意，当你改变你的方向活动重新创建因此onResume()也将被调用。
