This article mainly introduces the relevant knowledge of how to use local broadcasting in Android, the content is detailed and easy to understand, the operation is simple and fast, and it has a certain reference value. I believe you will gain something after reading this Android article on how to use local radio. Let's take a look.

MainActivity code

Package com.example.luobo.mybroadcastreceiver;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.IntentFilter;import android.support.v4.content.LocalBroadcastManager;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.widget.Button;import android.widget.Toast;public class MainActivity extends AppCompatActivity implements View.OnClickListener {private Button button; private IntentFilter intentFilter; private LocalBroadcastManager localBroadcastManager; private LocalReceiver localReciiver @ Override protected void onCreate (Bundle savedInstanceState) {super.onCreate (savedInstanceState); setContentView (R.layout.activity_main); button = (Button) findViewById (R.id.send_button); button.setOnClickListener (this); localBroadcastManager = LocalBroadcastManager.getInstance (this); / / use intentFilter = new IntentFilter (); intentFilter.addAction ("com.example.luobo.mybroadcastreceiver.LOCAL_BROADCAST"); localReciiver = new LocalReceiver (); localBroadcastManager.registerReceiver (localReciiver,intentFilter) } @ Override protected void onDestroy () {super.onDestroy (); localBroadcastManager.unregisterReceiver (localReciiver);} @ Override public void onClick (View view) {Intent intent = new Intent ("com.example.luobo.mybroadcastreceiver.LOCAL_BROADCAST"); localBroadcastManager.sendBroadcast (intent);} class LocalReceiver extends BroadcastReceiver {@ Override public void onReceive (Context context, Intent intent) {Toast.makeText (context, "received local broadcast", Toast.LENGTH_SHORT). Show ();}

First of all, the instance is obtained through the getInstance (this) method of LocalBroadcastManager (local broadcast management class). When registering the broadcast message, the registerReceiver (parameter 1, parameter 2) method of the localBroadcastManager instance is called (parameter 1 is the local broadcast receiver, parameter 2 is that the filter only selects to receive the specific broadcast message), and the sendBroadcast (Initent initent) method of the localBroadcastManager instance is called to send the broadcast message.

Package com.example.luobo.mybroadcastreceiver;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.widget.Toast;public class MyReceiver extends BroadcastReceiver {@ Override public void onReceive (Context context, Intent intent) {Toast.makeText (context, "Received in MyBroadCastReceiver", Toast.LENGTH_SHORT) .show (); abortBroadcast ();}}
