  </intent-filter>
</receiver>

MainActivity.java

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

  btn1 = (Button)findViewById(R.id.btn1);

  // 发送有序广播---静态注册
       btn1.setOnClickListener(new OnClickListener() {
    
    @Override
    public void onClick(View arg0) {
      
      Intent intent = new Intent();
      intent.setAction("xyz.lgch.onderedreceiver_Action_receiver");
      intent.putExtra("message", "发送有序广播 www.lgch.xyz");
      
      sendOrderedBroadcast(intent, "my.permission.receiver");
      
    }
  }); 
}

MyReceiver.java

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.view.Gravity;
import android.widget.Toast;

// 创建  接收广播
public class MyReceiver extends BroadcastReceiver {

  @Override
  public void onReceive(Context context, Intent arg1) {
    // TODO Auto-generated method stub
    String message = "广播信息" + arg1.getStringExtra("message");
    Toast toast = Toast.makeText(context, message, 3000);
    toast.setGravity(Gravity.TOP, 0, 0);
    toast.show();
  }
