Android FM播放時拔出耳機或者進入飛行模式，FM APP出現相應提示框，然後自動停止 m

正文      部分客戶要求如下： 1.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 ; 2.FM播放時進入飛行模式後,FM APP出現“進入飛行模式，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) {     LogUtils.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(sHandler11.obtainMessage(MSG_EXIT_FM, FMRadioService.this),(long) 1000); mFmServiceHandler.removeCallbacksAndMessages(null); stopFMFocusLoss(AudioManager.AUDIOFOCUS_LOSS); }  else  sHandler11.removeMessages(MSG_EXIT_FM);   4.修改onReceive 方法,這樣子就可以在進入飛行模式時顯示toast以及在關閉Fm app了         public void onReceive(Context context, Intent intent) 在 else {                 LogUtils.w(TAG, "Error: undefined action.");   } 之前添加： else if(Intent.ACTION_AIRPLANE_MODE_CHANGED.equals(action)){        boolean isAirPlaneMode = intent.getBooleanExtra("state",false);        if(isAirPlaneMode){            LogUtils.d(TAG, ">>>ACTION_AIRPLANE_MODE_CHANGED");            if (mIsPowerUp) {                   showToast(getString(R.string.toast_fm_enter_airplane_mode));                    sHandler11.sendMessageDelayed(sHandler.obtainMessage(MSG_EXIT_FM, FMRadioService.this),(long)1000);                    mFmServiceHandler.removeCallbacksAndMessages(null);                    stopFMFocusLoss(AudioManager.AUDIOFOCUS_LOSS);                    }              }   }   4.修改    public void onCreate()  在        filter.addAction(Intent.ACTION_SCREEN_OFF); 之後添加        filter.addAction(Intent.ACTION_AIRPLANE_MODE_CHANGED);   5.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> <string name="toast_fm_enter_airplane_mode">The FM will close because you have been entered the airplane mode</string>
