android FM播放時拔出耳機後,FM APP出現"拔出耳機，Fm停止"的提示框

客戶要求FM播放時拔出耳機後,FM APP出現“拔出耳機，Fm停止"的提示框，然後自動close

修改FMRadioService.java
1.添加如下import,以便能顯示toast
////AAAAA add start
import android.widget.Toast;
////AAAAA add end
public class FMRadioService extends Service implements FMRecorder.OnRecorderStateChangedListener {
 
2.在下面函數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,這樣子就可以顯示toast以及關閉Fm app了
在  switchAntennaAsync(mValueHeadSetPlug);
之後添加：
 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>
