1.MainActivity2.java中的代码,主要是使用意图发送广播
public class MainActivity2 extends Activity{ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.receiver_demo); }; public void click(View view){ Intent intent=new Intent(); intent.setAction("com.example.brocast.nimei"); sendBroadcast(intent); }
2.在Manifest.xml过滤意图,然后设置BrocastReceiver所在的类文件
<receiver android:name="com.example.brocastreceiverdemo.BrocastReceiverDemo2" > <intent-filter> <action android:name="com.example.brocast.nimei" /> </intent-filter> </receiver>
3、receiver.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="wrap_content" android:layout_height="wrap_content" android:onClick="click" android:text="发送自定义广播" /> </LinearLayout>
4. 自定广播的代码
public class BrocastReceiverDemo2 extends BroadcastReceiver{ @Override public void onReceive(Context arg0, Intent arg1) { // TODO Auto-generated method stub Toast.makeText(arg0, "我是自定义的广播", 1).show(); } }
