启动和停止广播接收器

我想通过两个按钮启动和停止广播接收器。 我已经在两个按钮侦听器中为此编写了代码。

代码如下：-

在startButton中我编写了注册接收器的代码如下

     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");
        }
    });

在停止按钮中，我已将停止接收器的调用编写为

   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");
        }
    });

当收到新呼叫时，侦听器仍在呼叫

您可以尝试此代码enable and disable BroadcastReceiver..我希望这能帮到您..

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();
   }
