Question

我认为我的代码中存在一个简单的问题，但我无法理解。我有一个HeaderService，显示一些特定应用程序的气泡弹出窗口。现在我想要的是当用户使用BroadCastReceiver按Home键或Back键时停止该服务。请查看我的代码并建议我一些解决方案。在此先感谢!!

这是我的Receiver类

public class PopupClosingReceiver extends BroadcastReceiver {


private boolean isMyServiceRunning(Context con) {
    ActivityManager manager = (ActivityManager) con.getSystemService(Context.ACTIVITY_SERVICE);
    for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
        if (HeaderService.class.getName().equals(service.service.getClassName())) {
            return true;
        }
    }
    return false;
}

@Override
public void onReceive(Context context, Intent intent) {

    if(isMyServiceRunning(context)){

        Intent serviceIntent = new Intent(context, HeaderService.class);
        context.stopService(serviceIntent);

    }

}

的AndroidManifest.xml

<receiver android:name=".PopupClosingReceiver">
        <intent-filter>
            <category android:name="android.intent.category.HOME"/>
        </intent-filter>
    </receiver>

Answer 1

您可以随时访问该服务，因为该服务已在系统中注册（“线程”）等待激活或随时停止。

示例：

 public class Phonecall extends BroadcastReceiver {

   @Override
   public void onReceive(Context context, Intent intent) {

    Intent song_wweather=  new Intent(context,Song_weather.class); //service class
  if(intent.getAction()=="android.intent.action.PHONE_STATE"){

TelephonyManager telephonyManager =
        (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);

PhoneStateListener callStateListener = new PhoneStateListener() {
    public void onCallStateChanged(int state, String incomingNumber)
    {
        if(state==TelephonyManager.CALL_STATE_RINGING){
            context.stopService(song_wweather);
        }


        if(state==TelephonyManager.CALL_STATE_IDLE){
            context.startService(song_wweather);
        }
    }
};
telephonyManager.listen(callStateListener,PhoneStateListener.LISTEN_CALL_STATE);



}}
}

     public void sendSMS { 

     

ActivityManager am=   (ActivityManager) context.getSystemService( Activity.ACTIVITY_SERVICE );

 List<ActivityManager.RunningServiceInfo> rs = am.getRunningServices(50);

String message = null; 

for (int i=0; i<rs.size(); i++) {
    ActivityManager.RunningServiceInfo rsi = rs.get(i);
    Log.i("Service", "Process " + rsi.process + " with component "
