Android音乐搜索栏无效(空闲)
作者:互联网
我正在从url播放mp3文件,但SeekBar在播放歌曲时没有更新.
当我试图强行移动然后从开始播放歌曲.
我正在使用以下代码来播放和更新SeekBar.
我想创建一个跟踪媒体播放器进度的搜索栏,但它不能很好地工作,音乐正在播放,但搜索栏保持空闲状态.有什么东西我遗漏了吗?
我想我不是从正确的位置调用updateSeekBar()方法…所以尝试更改updateSeekBar()的位置但没有工作…
我错过了什么……?请帮助….我是Android新手…
Activity.java
Play = findViewById(R.id.Play_button);
Play.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
play (url);//Song Url
}
});
private void play(String url) {
if (mediaPlayer != null && mediaPlayer.isPlaying()) {
mediaPlayer.stop();
}
mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
try {
if (temp == playurl.length) {
temp = 0;
play(playurl[temp]);
t1.setText(mobileArray[temp]);
} else {
temp = temp + 1;
play(playurl[temp]);
t1.setText(mobileArray[temp]);
}
}catch(ArrayIndexOutOfBoundsException exception) {
temp = 0;
play(playurl[temp]);
t1.setText(mobileArray[temp]);
}
}
});
mediaPlayer.setDataSource(url);
} catch (IllegalArgumentException e) {
Toast.makeText(getApplicationContext(), "Please Check Your Internet Connection!", Toast.LENGTH_LONG).show();
} catch (SecurityException e) {
Toast.makeText(getApplicationContext(), "Please Check Your Internet Connection!", Toast.LENGTH_LONG).show();
} catch (IllegalStateException e) {
Toast.makeText(getApplicationContext(), "Please Check Your Internet Connection!", Toast.LENGTH_LONG).show();
} catch (IOException e) {
e.printStackTrace();
}catch (Exception ex){
String err = (ex.getMessage()==null)?"SD Card failed":ex.getMessage();
Log.e("sdcard-err2:",err);
}
try {
mediaPlayer.prepare();
} catch (IllegalStateException e) {
Toast.makeText(getApplicationContext(), "Please Check Your Internet Connection!", Toast.LENGTH_LONG).show();
} catch (IOException e) {
Toast.makeText(getApplicationContext(), "Please Check Your Internet Connection!", Toast.LENGTH_LONG).show();
}catch (Exception ex){
String err = (ex.getMessage()==null)?"SD Card failed":ex.getMessage();
Log.e("sdcard-err2:",err);
}
try {
mediaPlayer.start();
}catch (Exception ex){
String err = (ex.getMessage()==null)?"SD Card failed":ex.getMessage();
Log.e("sdcard-err2:",err);
}
finalTime = mediaPlayer.getDuration();
updateSeekBar();
startTime = mediaPlayer.getCurrentPosition();
}
private void updateSeekBar() {
seekBar.setProgress((int) (((float) mediaPlayer.getCurrentPosition() / mediaFileLength) * 100));
if (mediaPlayer.isPlaying()) {
Runnable updater = new Runnable() {
@Override
public void run() {
updateSeekBar();
}
};seekBar.post(updater);
}
}
@Override
public void onBufferingUpdate(MediaPlayer mp, int percent) {
seekBar.setSecondaryProgress(percent);
}
解决方法:
试试这个
mediaFileLength = mediaPlayer.getDuration();
realtimeLength = mediaFileLength;
mediaPlayer.start();
finalTime = mediaPlayer.getDuration();
startTime = mediaPlayer.getCurrentPosition();
updateSeekBar();
