Android自定义广播接收

本文实例为大家分享了Android自定义广播接收的具体代码，供大家参考，具体内容如下

实现效果：

MainActivity.java代码：

package com.henu.broadcastsample;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
   private MyBroadcastReceiver receiver;

@Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
   }

public void send(View v) {
       //动态注册广播接收
       receiver = new MyBroadcastReceiver();
       String action = "henurjxy";
       IntentFilter intentFilter=new IntentFilter(action);
       registerReceiver(receiver,intentFilter);
       Intent intend = new Intent("henurjxy");
       sendBroadcast(intend);
   }
//在页面销毁时，注销广播接收者
   @Override
   protected void onDestroy() {
       super.onDestroy();
       unregisterReceiver(receiver);
   }
}

MyBroadcastReceiver.java代码：

package com.henu.broadcastsample;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;

public class MyBroadcastReceiver extends BroadcastReceiver {
public  MyBroadcastReceiver(){}
   @Override
   public void onReceive(Context context, Intent intent) {
       Toast.makeText(context,"是我发出的广播哦",Toast.LENGTH_SHORT).show();
   }
}
