我正在制作一个简单的应用程序来播放在线广播流.我知道如何设置流.到目前为止,这是我的代码.它设置流并播放它.但如果我停下来,我就无法重新开始.我错过了一些明显的东西吗
final MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mediaPlayer.setDataSource(url);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
mediaPlayer.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} // might take long! (for buffering,etc)
streamButton = (ToggleButton) findViewById(R.id.playstopstream);
streamButton.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton arg0,final boolean isChecked) {
// TODO Auto-generated method stub
new Thread(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
if(isChecked)
{
mediaPlayer.start();
}
else
{
mediaPlayer.stop();
mediaPlayer.reset();
}
}
解决方法
当您调用mediaPlayer.reset()时,mediaPlayer将进入IDLE状态.
要进行播放,您应该在开始之前进行初始化以准备.
