Android自定义Notification布局的实现方法

1、自定义一个带按钮的Notification布局：layout_notification；

2、创建Notification

RemoteViews views = new RemoteViews(getPackageName(),R.layout.layout_nitification);　　//自定义的布局视图

//按钮点击事件：

PendingIntent homeIntent = PengdingIntent.getBroadcast(this,1,new Intent("action"),PengdingIntent.FLAG_UPDATE_CURRENT);

views.setOnClickPendingIntent(R.id.btn,homeIntent);　　　　//点击的id，点击事件

//创建通知：

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext);

mBuilder.setContent(views)　　　　//设置布局

　　　　　.setOngoing(true)　　　　//设置是否常驻,true为常驻

　　　　　.setSmallIcon(R.mipmap.ic_laucher)　　　　//设置小图标

　　　　　.setTicker("通知来了")　　　　　　　　//设置提示

　　　　　.setPriority(Notification.PRIORITY_MAX)　　//设置优先级

　　　　　.setWhen(System.currentTimeMillis())　　　　//设置展示时间

　　　　　.setContentIntent(PendingIntent.getBroadcast(this,2,new Intent("action.view"),PengingIntent.FLAG_UPDATE_CURRENT);　　　　//设置视图点击事件

NotificationManager mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);

mNotificationManager.notify(100,mBuilder.build())　　　　//显示通知： 当前notificationid，当前notification

3、创建NotificationBroadcast接收通知

public class NotificationBroadcast extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();　　　　//动作
        collapseStatusBar(context);　　　　　　　　//收起通知栏
        Intent i = new Intent(context,MainActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);　　　　//必须添加，避免重复打开
        if (action.equals("com.xczl.smart.notification.home")){
            i.putExtra("flag","home");　　　　//传值
            context.startActivity(i);
        }
    }　

    public void collapseStatusBar(Context context) {
        try {
            Object statusBarManager = context.getSystemService("statusbar");
            Method collapse;
            if (Build.VERSION.SDK_INT <= 16) {
                collapse = statusBarManager.getClass().getMethod("collapse");
            } else {
                collapse = statusBarManager.getClass().getMethod("collapsePanels");
            }
            collapse.invoke(statusBarManager);
        } catch (Exception localException) {
            localException.printStackTrace();
        }
    }

4、配置清单

MainActivity：设置LanchMode为singleTask
注册Broadcast：
<receiver
    android:name="com.xczl.smart.broadcast.NotificationBroadcast"
    android:enabled="true">
    <intent-filter>
        <action android:name="action"/>
        <action android:name="action.view"/>
    </intent-filter>
</receiver>
配置通知栏伸缩权限：　　
<uses-permission android:name="android.permission.EXPAND_STATUS_BAR"/>

5、MainActivity接收消息

//覆写 onNewIntent()
@Override
protected void onNewIntent(Intent intent) {
   String extra = intent.getStringExtra("flag");
   if (!TextUtils.isEmpty(extra)){
      if (extra.equals("home")){
         //接收到值的具体操作
      }
   }
}

代码示例：

a、类GlobalDeclare

public class GlobalDeclare {

    //notification点击广播
    public final static String ACTION_NOTIFICATION_CLICK = "com.ACTION_NOTIFICATION_CLICK";

}

b、类NotifyClickReceiver

/**
 * 全局广播
 * Created by xl on 2018/5/9.
 */
public class NotifyClickReceiver extends BroadcastReceiver {

    private final static String TAG = NotifyClickReceiver.class.getSimpleName();

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if(GlobalDeclare.ACTION_NOTIFICATION_CLICK.equals(action)){
            MyLogger.i(TAG, "broadcast");
        }
    }
}

c、清单文件声明

<receiver android:name=".NotifyClickReceiver">
    <intent-filter>
        <action android:name="com.ACTION_NOTIFICATION_CLICK" />
    </intent-filter>
</receiver>

d、showNotification函数

public void showNotification(Context context, String title, String msg) {
    NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
    builder.setAutoCancel(true);//点击后消失
    builder.setSmallIcon(R.mipmap.ic_launcher);//设置通知栏消息标题的头像
    builder.setDefaults(NotificationCompat.DEFAULT_ALL);//设置通知铃声，震动，闪光灯
    builder.setTicker(context.getText(R.string.app_name));
    builder.setContentTitle(title);
    builder.setContentText(msg);
    //Intent intent = new Intent();//只显示通知，无页面跳转
    Intent intent = new Intent(GlobalDeclare.ACTION_NOTIFICATION_CLICK);//将要跳转的界面
    //intent.setAction(GlobalDeclare.ACTION_NOTIFICATION_CLICK);
    //Intent intent = new Intent(context, NotifyClickReceiver.class);//将要跳转的界面
    //利用PendingIntent来包装我们的intent对象,使其延迟跳转
    int id = (int) (System.currentTimeMillis() / 1000);
    PendingIntent intentPend = PendingIntent.getBroadcast(context, id, intent, PendingIntent.FLAG_CANCEL_CURRENT);
    builder.setContentIntent(intentPend);
    NotificationManager manager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
    manager.notify(0, builder.build());
}

完！！！
