Broadcast创建静态广播

首先创造接收类继承BroadcastReceiver

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

public class MyR1eceive extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String message = intent.getStringExtra("MESSAGE");
        Log.i("godv", "MyR1eceive--接收广播" + message);
    }

    public MyR1eceive() {
        Log.i("godv", "MyR1eceive--创建");
    }
}

在AndroidManifest.xml中进行注册

<receiver
    android:name=".MyR1eceive"
    android:enabled="true"
    android:exported="true">
    <intent-filter>
        <action android:name="godv" />
    </intent-filter>
</receiver>

具体位置：

这面接收端就完成了

现在开始发送端

发送端-xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:onClick="sendNormalBC"
        android:text="发送一般广播" />

    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</LinearLayout>

发送端-java代码

public class MainActivity extends AppCompatActivity {

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

    public void sendNormalBC(View v) {
        Log.i("godv", "发送广播");
        //隐式意图 跟接收器的action对应
        Intent intent = new Intent("godv");
        intent.putExtra("MESSAGE", "godv");
        intent.setPackage("com.example.broadcastr");
       //intent.setClassName("com.example.broadcastr","com.example.broadcastr.MyR1eceive");
        sendBroadcast(intent);
        Toast.makeText(this, "发送一般广播", Toast.LENGTH_SHORT).show();
    }

}
