@xhen後，使用下面這段代碼運行完美，
在XML佈局添加此
<sg.xyz.test.util.CustomVideoView
android:id="@+id/videoview"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:layout_alignParentTop="true"
/>
在片段級呼叫這些medthods
private MediaController mediaController;
private Uri uri;
public void setupVideo(){
if (mediaController == null) {
mediaController = new
MediaController(mContext);
mediaController.setAnchorView(mBinding.videoview);
mBinding.videoview.setMediaController(mediaController);
}
try {
uri = Util.buildURiPath(resourceID);
mBinding.videoview.setVideoURI(uri);
} catch (Exception e) {
Logger.debug("Error: " + e.getMessage());
e.printStackTrace();
}
mBinding.videoview.requestFocus();
mBinding.imageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mBinding.videoview.start();
mBinding.imageView.setVisibility(View.INVISIBLE);
}
});
mBinding.videoview.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.setOnVideoSizeChangedListener(new MediaPlayer.OnVideoSizeChangedListener() {
@Override
public void onVideoSizeChanged(MediaPlayer mediaPlayer, int width, int height) {
mediaController.setAnchorView(mBinding.videoview);
}
});
Logger.debug("Duration = " +
mBinding.videoview.getDuration());
}
});
mBinding.videoview.setOnErrorListener(new MediaPlayer.OnErrorListener() {
@Override
public boolean onError(MediaPlayer mp, int what, int extra) {
AlertDialogFactory.buildAlertDialog(mContext, 0, R.string.video_playing_error).show();
return false;
}
});
}
public static Uri buildURiPath(int resourceID)
{
String uriPath = String.valueOf(Uri.parse("android.resource://" + LoginActivity.PACKAGE_NAME + "/"
+resourceID));
Uri uri = Uri.parse(uriPath);
return uri;
}
與video對象就是它替換此mBinding.videoview。 現在，創建CustomVideoView類
public class CustomVideoView extends VideoView {
private int width;
private int height;
private Context context;
private VideoSizeChangeListener listener;
private boolean isFullscreen;
public CustomVideoView(Context context) {
super(context);
init(context);
}
public CustomVideoView(Context context, AttributeSet attrs) {
super(context, attrs);
init(context);
}
/**
* get video screen width and height for calculate size
*
* @param context Context
*/
private void init(Context context) {
this.context = context;
setScreenSize();
}
/**
* calculate real screen size
*/
private void setScreenSize() {
Display display = ((Activity) context).getWindowManager().getDefaultDisplay();
if (Build.VERSION.SDK_INT >= 17) {
//new pleasant way to get real metrics
DisplayMetrics realMetrics = new DisplayMetrics();
display.getRealMetrics(realMetrics);
width = realMetrics.widthPixels;
height = realMetrics.heightPixels;
} else if (Build.VERSION.SDK_INT >= 14) {
//reflection for this weird in-between time
try {
Method mGetRawH = Display.class.getMethod("getRawHeight");
Method mGetRawW = Display.class.getMethod("getRawWidth");
width = (Integer) mGetRawW.invoke(display);
height = (Integer) mGetRawH.invoke(display);
} catch (Exception e) {
//this may not be 100% accurate, but it's all we've got
width = display.getWidth();
height = display.getHeight();
}
} else {
//This should be close, as lower API devices should not have window navigation bars
width = display.getWidth();
height = display.getHeight();
}
// when landscape w > h, swap it
if (width > height) {
int temp = width;
width = height;
height = temp;
}
}
/**
* set video size change listener
*
*/
public void setVideoSizeChangeListener(VideoSizeChangeListener listener) {
this.listener = listener;
}
public interface VideoSizeChangeListener {
/**
* when landscape
*/
void onFullScreen();
/**
* when portrait
*/
void onNormalSize();
}
@Override
public void setVideoURI(Uri uri) {
MediaMetadataRetriever retriever = new MediaMetadataRetriever();
retriever.setDataSource(this.getContext(), uri);
width = Integer.parseInt(retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_WIDTH));
height = Integer.parseInt(retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_HEIGHT));
super.setVideoURI(uri);
super.setVideoURI(uri);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if (context.getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
// full screen when landscape
setSize(height, width);
if (listener != null) listener.onFullScreen();
isFullscreen = true;
} else {
// height = width * 9/16
setSize(width, width * 9/16);
if (listener != null) listener.onNormalSize();
isFullscreen = false;
}
}
/**
* @return true: fullscreen
*/
public boolean isFullscreen() {
return isFullscreen;
}
/**
* set video sie
*
* @param w Width
* @param h Height
*/
private void setSize(int w, int h) {
setMeasuredDimension(w, h);
getHolder().setFixedSize(w, h);
}
}
請添加日誌，以幫助您更好，是什麼問題？ –
