发送一般广播:

public class MainActivity extends Activity {

private Button btn1,btn2;

 

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

btn2=(Button)this.findViewById(R.id.button2);

btn1.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// 多个广播接收者发送广播

Intent intent=new Intent();

intent.putExtra("name", "李华");

intent.setAction("com.yqq.mutilBrocast");

sendBroadcast(intent);

}

});

配置文家:

 <receiver 

            android:name="com.example.android_brocast_order.BroadCast1"

            >

            <!-- 设置优先权整数越大优先权越大 -->

            <intent-filter android:priority="1">

              <intent-filter android:priority="9">
