Android 视频播放器的方向改变

Question

我有一个视频播放器。并希望同时启用横向和纵向。但问题是播放器每次在方向改变时都会下载文件。我已经尝试使用 "onCofigurationChange"，但它仍然无法正常工作。我该如何解决这个问题？

P.S。我已经更改了 AndroidManifest.xml 文件并添加了

android:configChanges="orientation|screenSize|keyboardHidden"

所以问题出在我的 java 文件中。

这是我的代码：

public class VideoViewActivity extends Activity {

ProgressDialog pDialog;
VideoView videoview;

String VideoURL = "http://v.mover.uz/ep83Sfim_s.mp4";


public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.videoview_main);

    if (Build.VERSION.SDK_INT < 16) {
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
    }
    else
    {
        View decorView = getWindow().getDecorView();
    // Hide the status bar.
        int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
        decorView.setSystemUiVisibility(uiOptions);
    // Remember that you should never show the action bar if the status bar is hidden, so hide that too if necessary.
        ActionBar actionBar = getActionBar();
        actionBar.hide();
    }

    //        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);


    setupActivity();

}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    setContentView(R.layout.videoview_main);

    setupActivity();
}

public void setupActivity() {
    videoview = (VideoView) findViewById(R.id.VideoView);
            // Create a progressbar
    pDialog = new ProgressDialog(VideoViewActivity.this);
    // Set progressbar message
    pDialog.setMessage("Buffering...");
    pDialog.setIndeterminate(false);
    pDialog.setCancelable(false);
    // Show progressbar
    pDialog.show();

    try {
        // Start the MediaController
        MediaController mediacontroller = new MediaController(
                VideoViewActivity.this);
        mediacontroller.setAnchorView(videoview);
        // Get the URL from String VideoURL
        Uri video = Uri.parse(VideoURL);
        videoview.setMediaController(mediacontroller);
        videoview.setVideoURI(video);

    } catch (Exception e) {
        Log.e("Error", e.getMessage());
        e.printStackTrace();
    }

    videoview.requestFocus();
    videoview.setOnPreparedListener(new OnPreparedListener() {
        // Close the progress bar and play the video
        public void onPrepared(MediaPlayer mp) {
            pDialog.dismiss();
            videoview.start();
        }
    });
  }
}

在你的 onConfigurationChanged 中应该是：

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    //if you need change layout then do:  
    switch(newConfig.orientation) {
        case Configuration.ORIENTATION_LANDSCAPE:
            setContentView(layout_landscape)
            break;
        case Configuration.ORIENTATION_PORTRAIT:
            setContentView(layout_portrait);
            break;
    }
}

无需再次调用 setContentView(R.layout.videoview_main) and setupActivity()。

并且还需要在您的 AdroidManifest 中添加 <activity android:name="<Your_video_avtivity>" android:configChanges="orientation" />。
