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();
