客户要求FM播放时拔出耳机后,FM APP出现“拔出耳机，Fm停止"的提示框，然后自动close

修改FMRadioService.java

1.添加如下import,以便能显示toast
AAAAA add start
import android.widget.Toast;
AAAAA add end

public class FMRadioService extends Service implements FMRecorder.OnRecorderStateChangedListener {

 

2.在下面函数onBind()前添加 
//AAAAA add start
 public static final int MSG_EXIT_FM = 1234;
 private Handler sHandler11 = new Handler() {
   @Override
   public void handleMessage(Message msg) {
    FMRadioLogUtils.d(TAG, "sHandler11 =  " + msg.what);
    switch (msg.what) {
     case MSG_EXIT_FM:
      android.os.Process.killProcess(android.os.Process.myPid());
      break;
    }
   }
 };

 private Toast mToast = null;

 private void showToast(CharSequence text) {
 if (null == mToast) {
     mToast = Toast.makeText(mContext, text, Toast.LENGTH_SHORT);
     }
        mToast.setText(text);
        mToast.show();
        LogUtils.v(TAG, "FMRadioActivity.showToast: toast = " + text);
    };
//AAAAA add end
@Override
    public IBinder onBind(Intent intent) {
        return mBinder;
    }

 

3.修改onReceive 方法,这样子就可以显示toast以及关闭Fm app了
在  switchAntennaAsync(mValueHeadSetPlug);
之后添加：
 if(mValueHeadSetPlug == 1 && mIsPowerUp )
{
   showToast(getString(R.string.toast_plugin_headphone_before_FM));
   sHandler11.sendMessageDelayed(sHandler.obtainMessage(MSG_EXIT_FM, FMRadioService.this),(long)

1000);

mFmServiceHandler.removeCallbacksAndMessages(null);
stopFMFocusLoss(AudioManager.AUDIOFOCUS_LOSS);
}
 else
 sHandler11.removeMessages(MSG_EXIT_FM);

 

4.在alps\mediatek\packages\apps\FMRadio\res\values\ strings.xml中添加
<string name="toast_plugin_headphone_before_FM">The FM will close because you have been plug out

the headphone</string>
