MainActivity3.java 发送广播意图的Activity
public class MainActivity3 extends Activity{ @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.activity_main3); } //发送无序广播--新闻联播 public void click(View view){ Intent intent=new Intent(); intent.setAction("com.example.bro"); sendBroadcast(intent); } //发送有序广播--中央文件 public void click2(View view){ Intent intent=new Intent(); intent.setAction("com.example.bro"); sendOrderedBroadcast(intent, null, null, null, 0, "给农民兄弟的10000元", null); } }
在Manifest.xml文件中注册广播:
<receiver android:name="com.example.brocastreceiverdemo.Level1Broadcast"> <intent-filter android:priority="1000"> <action android:name="com.example.bro"/> </intent-filter> </receiver> <receiver android:name="com.example.brocastreceiverdemo.Level1Broadcast"> <intent-filter android:priority="1000"> <action android:name="com.example.bro"/> </intent-filter> </receiver> <receiver android:name="com.example.brocastreceiverdemo.Level2Broadcast"> <intent-filter android:priority="500"> <action android:name="com.example.bro"/> </intent-filter> </receiver> <receiver android:name="com.example.brocastreceiverdemo.Level3Broadcast"> <intent-filter android:priority="100"> <action android:name="com.example.bro"/> </intent-filter> </receiver> <receiver android:name="com.example.brocastreceiverdemo.Level4Broadcast"> <intent-filter android:priority="-1000"> <action android:name="com.example.bro"/> </intent-filter> </receiver>
3.xml布局文件:
<?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:text="发送无序广播" android:onClick="click" /> <Button android:layout_width="match_parent" android:layout_height="wrap_content" android:text="发送序广有播" android:onClick="click2" /> </LinearLayout>
4. 四个具体的brocastreceiver 类:
public class Level1Broadcast extends BroadcastReceiver { @Override public void onReceive(Context arg0, Intent arg1) { // TODO Auto-generated method stub // abortBroadcast();//发无序广播,此api不生效 System.out.println("中央发给农民兄弟的10000元钱"); } }
public class Level2Broadcast extends BroadcastReceiver { @Override public void onReceive(Context arg0, Intent arg1) { // TODO Auto-generated method stub System.out.println("省政府发给农民兄弟的5000元钱"); abortBroadcast();//发无序广播,此api不生效 } }
public class Level3Broadcast extends BroadcastReceiver { @Override public void onReceive(Context arg0, Intent arg1) { // TODO Auto-generated method stub System.out.println("县政府发给农民兄弟的2500元钱"); } }
public class Level4Broadcast extends BroadcastReceiver { @Override public void onReceive(Context arg0, Intent arg1) { // TODO Auto-generated method stub System.out.println("乡政府发给农民兄弟的1000元钱"); } }
