我有一个视频播放器，当我启动它并按下启动器图标并再次重新启动应用程序时，视频会从原来的位置开始播放。当我暂停视频并按下启动器图标并再次重新启动应用程序时。视频不在暂停状态。它再次从最后一个位置开始。提前致谢

最佳答案
请尝试创建一个状态 bool 值来检查视频是否是手动暂停。
boolean manual_pause = false;
在 onPause 中检查视频状态以影响 manual_pause。
@Override
public void onPause() {
super.onPause();
Log.i("positionPlayback", "onPause " + restoredPosition);
if (videoView != null && videoView.isPlaying()) {
videoView.pause();
manual_pause = false;
} else if(videoView != null){
manual_pause = true;
}
restoredPosition = videoView.getCurrentPosition();
editor.putInt("CURRENT_POSITION", restoredPosition);//stopPosition is an int
Utilities.hideKeybord(VideoFullscreenActivity.this);
}
然后在 onResume() 中检查此状态以预先设置视频状态。
@Override
public void onResume() {
super.onResume();
checkForCrashes();
startFromZero = false;
if (Utilities.checkInternetConnection(this)) {
Log.i("positionPlayback", "onResume " + restoredPosition);
pDialog.show();
videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
// Close the progress bar and play the video
public void onPrepared(MediaPlayer mp) {
pDialog.dismiss();
restoredPosition = prefs.getInt("CURRENT_POSITION", 0);
videoView.seekTo(restoredPosition);
if(manual_pause) {
videoView.pause();
manual_pause = false;
}else{
videoView.start();
}
}
});
} else {
Utilities.showAlertLoginDialog(this, "", getResources().getString(R.string.internet_unavailable_msg));
}
}
你必须像这样手动处理你以前的状态。
希望这对你有帮助...
