上一篇获取微信qq等三方通知（http://www.jianshu.com/p/eba0a679cd31），说了如何使用NotificationListenerService，以及操作过程中的几个大坑，现在利用NotificationListenerService实现短信、来电、微信、QQ消息监听。
1.还是先来一个类继承NotificationListenerService.
如下代码中，含一个参数的onNotificationPosted和onNotificationRemoved两个方法，每次来通知发现无响应，而含两个参数的onNotificationPosted和onNotificationRemoved就有响应。post是通知来时调用，removed是通知删除时调用。
public class NotifyService extends NotificationListenerService {
public static final String SEND_WX_BROADCAST="SEND_WX_BROADCAST";
@Override
public void onNotificationPosted(StatusBarNotification sbn) {
}
@Override
public void onNotificationRemoved(StatusBarNotification sbn) {
}
@Override
public void onNotificationPosted(StatusBarNotification sbn, RankingMap rankingMap) {
Log.e("AAA", "=2==onNotificationPosted ID :"
+ sbn.getId() + "\t"
+ sbn.getNotification().tickerText + "\t"
+ sbn.getPackageName());
String packageName=sbn.getPackageName();
Intent intent=new Intent();
intent.setAction(SEND_WX_BROADCAST);
Bundle bundle=new Bundle();
bundle.putString("packageName",packageName);
intent.putExtras(bundle);
this.sendBroadcast(intent);
}
@Override
public void onNotificationRemoved(StatusBarNotification sbn, RankingMap rankingMap) {
Log.e("AAA", "=4==onNotificationRemoved ID :"
+ sbn.getId() + "\t"
+ sbn.getNotification().tickerText
+ "\t" + sbn.getPackageName());
}
}
2.当然要在清单文件中注册这个服务
<service android:name=".NotifyService"
android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
<intent-filter>
<action android:name="android.service.notification.NotificationListenerService" />
</intent-filter>
<uses-permission android:name="android.permission.BIND_ACCESSIBILITY_SERVICE" />
</service>
3.使用广播把监听的包名传到需要的地方
因为NotificationListenerService这个服务提供了一个系统的对象，我们new出来的对象无法使用，所以我放弃使用接口回调，采用广播的方式传递包名。代码如上。
4.一个接口，在接收广播的地方，进行回调。
public interface MyMessage {
/**
* 电话来了
*/
public void comePhone();
/**
* 短信来了
*/
void comeShortMessage();
/**
* 微信消息
*/
void comeWxMessage();
/**
* qq消息
*/
void comeQQmessage();
}
5.一个类用于接收广播以及判断是否打开设置
public class ComeWxMessage {
private static final String ENABLED_NOTIFICATION_LISTENERS = "enabled_notification_listeners";
public static final String SEND_WX_BROADCAST="SEND_WX_BROADCAST";
public static final String QQ="com.tencent.mobileqq";
public static final String WX="com.tencent.mm";
public static final String MMS="com.android.mms";
public static final String CALL="com.android.incallui";
private MyMessage myMessage;
private Context context;
public ComeWxMessage(MyMessage myMessage, Context context) {
this.myMessage = myMessage;
this.context = context;
registBroadCast();
}
private BroadcastReceiver b=new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
Bundle bundle=intent.getExtras();
String pachageName=bundle.getString("packageName");
switch (pachageName){
case WX:
myMessage.comeWxMessage();
break;
case QQ:
myMessage.comeQQmessage();
break;
case MMS:
myMessage.comeShortMessage();
break;
case CALL:
myMessage.comePhone();
break;
}
}
};
private void registBroadCast() {
IntentFilter filter=new IntentFilter(SEND_WX_BROADCAST);
context.registerReceiver(b,filter);
}
public void unRegistBroadcast(){
context.unregisterReceiver(b);
}
public void openSetting(){
if (!isEnabled()) {
Intent intent = new Intent("android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS");
context.startActivity(intent);
} else {
Toast.makeText(context, "已开启服务权限", Toast.LENGTH_LONG).show();
}
}
private boolean isEnabled() {
String pkgName = context.getPackageName();
final String flat = Settings.Secure.getString(context.getContentResolver(),
ENABLED_NOTIFICATION_LISTENERS);
if (!TextUtils.isEmpty(flat)) {
final String[] names = flat.split(":");
for (int i = 0; i < names.length; i++) {
final ComponentName cn = ComponentName.unflattenFromString(names[i]);
if (cn != null) {
if (TextUtils.equals(pkgName, cn.getPackageName())) {
return true;
}
}
}
}
return false;
}
public void toggleNotificationListenerService() {
PackageManager pm = context.getPackageManager();
pm.setComponentEnabledSetting(
new ComponentName(context,com.mytestnotify.NotifyService.class),
PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
pm.setComponentEnabledSetting(
new ComponentName(context, com.mytestnotify.NotifyService.class),
PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
}
}
6.在MainActivity里面调用。当然不需要上面这个类，可以直接在MainActivity里面接收广播，但感觉太乱了。
public class MainActivity extends AppCompatActivity implements MyMessage{
private ComeWxMessage comeWxMessage;
private MyMessage myMessage;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myMessage=new MainActivity();
comeWxMessage=new ComeWxMessage(myMessage,this);
comeWxMessage.toggleNotificationListenerService();
comeWxMessage.openSetting();
}
@Override
public void comePhone() {
Log.e("AAA","====回调中，收到来电===");
}
@Override
public void comeShortMessage() {
Log.e("AAA","====回调中，收到短信消息===");
}
@Override
public void comeWxMessage() {
Log.e("AAA","====回调中，收到微信消息===");
}
@Override
public void comeQQmessage() {
Log.e("AAA","====回调中，收到QQ消息===");
}
@Override
protected void onDestroy() {
super.onDestroy();
comeWxMessage.unRegistBroadcast();
}
}
至此，就可以实现了。
本来对于短信和来电，我用另外的方法进行监听，但在监听微信的时候，幸得别人提醒使用NotificationListenerService。在进行测试的时候，发现来电、短信都可以通过通知栏
