由於某種原因,我的媒體播放器在暫停時完成。現在我已經看到另一篇文章說它是異步和300毫秒的差異,我明白了。但我的主要問題是,我在視頻上還剩20秒,暫停後在20秒內耗盡。 這裏是有關的代碼,我可能會搞砸的:MediaPlayer onCompletionListener在暫停時調用
private void initPlayer()
{
try {
if(videoFile != null)
{
afd = getAssets().openFd(videoFile);
instructionVideoPlayer = new MediaPlayer();
instructionVideoPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getDeclaredLength());
instructionVideoPlayer.setDisplay(holder);
instructionVideoPlayer.prepare();
Log.i("Instruction Video", "videoPrepared");
instructionVideoPlayer.setOnCompletionListener(instructionVideoComplete);
instructionVideoPlayer.setOnPreparedListener(this);
}
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
Log.i(this.toString(), "IOEXception");
e.printStackTrace();
//initPlayer();
} catch (Exception e)
{
Log.i("InitPlayer", e.getClass().toString());
e.printStackTrace();
}
restoreOverlayState();
}
聽衆:
MediaPlayer.OnCompletionListener instructionVideoComplete = new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer arg0) {
Log.i("onCompletion", "called");
if(!videoFile.contentEquals(LangSelect.INSTRUCTION_05))
{
Intent returnIntent = new Intent();
returnIntent.putExtra(LangSelect.ACTION, LangSelect.GO_VIDEO_NEXT);
setResult(RESULT_OK, returnIntent);
continuePlaying = true;
toFinish();
}
else
toFinish();
}
};
public void onPrepared(MediaPlayer mediaPlayer)
{
playVideo();
}
的播放和暫停功能
private void playVideo()
{
instructionVideoPlayer.seekTo(pausedAt);
instructionVideoPlayer.start();
restoreOverlayState();
}
private void pauseVideo()
{
pausedAt = instructionVideoPlayer.getCurrentPosition();
instructionVideoPlayer.pause();
}
private void restoreOverlayState()
{
prefs = getSharedPreferences(SAVE_PREFS, Context.MODE_PRIVATE);
if(prefs.getBoolean(IS_PAUSED, false))
{
pauseOverlay.setVisibility(View.VISIBLE);
pauseVideo();
}
else
{
pauseOverlay.setVisibility(View.GONE);
}
}
編輯:這只是發生在Nexus S(2.3.3)我正在測試的其中一款手機。另一個Galaxy S(Froyo)沒有這個錯誤。
