这里写图片描述

//普通默认的广播：1.广播接收器：public class MyReceiver1 extends BroadcastReceiver {    public MyReceiver1() {    }    //接收广播信息    @Override    public void onReceive(Context context, Intent intent) {        String i = intent.getStringExtra("info");        Toast.makeText(context, i, Toast.LENGTH_SHORT).show();    }}2.activity类：public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }    public void sendNormal(View v) {        Intent intent = new Intent("com.ke.action.MY_BROADCAST");//action字符相当于广播的频率一样        intent.putExtra("info", "this is boradcast");//要发送广播的内容        this.sendBroadcast(intent);//发送广播    }}
