启动和停止广播接收器

我想从两个按钮启动和停止广播接收器。我已经在两个按钮监听器中编写了代码。启动和停止广播接收器

的代码如下： -

在startButton我已经写的代码如下

 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"); 
     } 
    });

在我已经写呼吁停止接收机

停止按钮注册接收机

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"); 
     } 
    });

收听新电话时仍有收听者打电话

你把这个接收器还的Manifest.xml？ –

在清单

<receiver android:name="your receiver name">

主要活动

BroadcastReceiver br = new BroadcastReceiver() { 

     @Override 
     public void onReceive(Context context, Intent intent) { 
      Log.w("Check", "Inside On Receiver"); 
      Toast.makeText(getApplicationContext(), "received", Toast.LENGTH_SHORT).show(); 
     } 
    }; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     IntentFilter filter = new IntentFilter(); 
     filter.addAction(BROADCAST_ACTION); 
     filter.addCategory(Intent.CATEGORY_DEFAULT); 
     registerReceiver(br, filter); 

    } 

    @Override 
    protected void onPause() { 
     super.onPause(); 
     unregisterReceiver(br); 
    } 
}

你可以试试这个代码enable和disableBroadcastReceiver ..我希望这将帮助你..

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(); 
    }

制作确定你打电话给unregisterReceiver()我receiver您称为registerReceiver()的对象。如果您在释放它之前为同一个接收器创建新对象，那么已注册的旧接收器对象不能再注销，因为您已为其分配新的内存块。

例如，做到这一点：

MyBroadcastReceiver receiver = new MyBroadCastReceiver(); 
registerReceiver(receiver); 
unregisterReceiver(receiver); 

receiver = new MyBraodCastReceiver();
