启动和停止广播接收器 [英] Start and stop broadcast receiver

问题描述

我要开始和两个按钮停止广播接收机。
我写的code这两个按钮的监听器。

I want to start and stop a broadcast receiver from two buttons. I had written the code for this in two button listeners.

在code如下： -

The code is as follows:-

在startButton我已经写了code为如下注册接收

In startButton I have written the code for registering receiver as follows

     startCallBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            startCallBtn.setVisibility(View.INVISIBLE);
            stopCallBtn.setVisibility(View.VISIBLE);


            //register call receiver.
            registerReceiver(callReceiver, new IntentFilter(
            "android.intent.action.CALL"));
           System.out.println("Registered Call Receiver Perfectly");
        }
    });

在停止按钮我已经写了要求停止接收器

In a stop button I have written the call for stop receiver as

   stopCallBtn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            stopCallBtn.setVisibility(View.INVISIBLE);
            startCallBtn.setVisibility(View.VISIBLE);
            stopService(new Intent(MainActivity.this, SpeakOut.class));
            FileOutputStream fos;

          //Unregister sms receivers
            unregisterReceiver(callReceiver);
            System.out.println("Unregistered Call Broadcast Receiver");
        }
    });

还是在新的呼叫接收听众呼吁

still the listener is calling when new call is receiving

推荐答案

您可以试试这个code为启用和禁用 广播接收器 ..我希望这会帮助你。

You can try this code for enable and disable BroadcastReceiver..I hope this will help you..

public void enableBroadcastReceiver(View view)
{

    ComponentName receiver = new ComponentName(this, AlarmManagerBroadcastReceiver.class);
    PackageManager pm = this.getPackageManager();

    pm.setComponentEnabledSetting(receiver,
            PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
            PackageManager.DONT_KILL_APP);
    Toast.makeText(this, 'Enabled broadcast receiver', Toast.LENGTH_SHORT).show();
   }
   /**
    * This method disables the Broadcast receiver registered in the AndroidManifest file.
    * @param view
    */
   public void disableBroadcastReceiver(View view){
    ComponentName receiver = new ComponentName(this, AlarmManagerBroadcastReceiver.class);
    PackageManager pm = this.getPackageManager();
        pm.setComponentEnabledSetting(receiver,
            PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
            PackageManager.DONT_KILL_APP);
    Toast.makeText(this, 'Disabled broadcst receiver', Toast.LENGTH_SHORT).show();
   }
