在使用MediaPlayer播放音频时报出 E/MediaPlayerNative: start called in state 1, mPlayer(0x0)
代码语言：javascript复制@Override
public void onClick(View v){
Bundle b = new Bundle ();
switch(v.getId ()){
case R.id.start: //获取一个Message变量，用来传递点击状态的值
msg = myHandle.obtainMessage (); //把状态的值放在Bundle对象里面
b.putInt(“status”,1);
msg.setData(b);
msg.sendToTarget ();
break;
case R.id.pause:
msg = myHandle.obtainMessage ();
b.putInt("status",2);
msg.setData(b);
msg.sendToTarget ();
break;
case R.id.restart:
msg = myHandle.obtainMessage ();
b.putInt("status",3);
msg.setData(b);
msg.sendToTarget ();
break;
case R.id.stop:
msg = myHandle.obtainMessage ();
b.putInt("status",4);
msg.setData(b);
msg.sendToTarget ();
break;
}
}
class MyHandle extends Handler{
public MyHandle(){
}
public MyHandle(Looper looper){
super(looper);
}
@Override
public void handleMessage(Message msg){
Bundle b = msg.getData ();
int status = b.getInt("status");
if(status == 1){
mMediaPlayer.start ();
}else if (status ==2){
mMediaPlayer.pause();
}else if(status == 3){
mMediaPlayer.seekTo(0);
}else if(status == 4){
mMediaPlayer.stop();
mMediaPlayer.release ();
mMediaPlayer = null;
VideoActivity.this.finish ();
}
