问题描述

我有一个背景服务这是不绑定到任何应用程序（或活动）的。它监控传入的消息，并在收到消息，我都显示一个对话框弹出。我试图定义一个方法，它是显示警告对话框，但它给例外，因为内螺纹无法创建处理程序，并没有所谓的活套。prepare（） 我真的没有关于如何解决这个问题的任何想法。我已经搜查了许多后像这样在这里，但没有得到如何解决这一个。帮助高AP preciated。谢谢你。

I am having a background Service which is not binded to any of the application(or Activity). It's monitoring incoming messages, and on receiving message, I have to show one dialog popup. I have tried defining one method which is for showing alert dialog, but it gives exception as "Can't create handler inside thread that has not called Looper.prepare()" I really don't have any idea regarding how to solve this problem. I have searched many post like this over here but not getting how to resolve this one. Help highly appreciated. Thanks.

推荐答案

创建一个处理程序分开是这样的。

Create a Handler seperately like this.

private Handler handler = new Handler() {
 @Override
 public void handleMessage(Message msg) {

//Call you method in This one...
 displayDialog(); or whatever method name is
 }
};

现在，您所呼叫的displayDialog（）方法或什么都命名对话框。替换以下code。

Now where you are calling the displayDialog() method or what ever named dialog. replace the following code.

handler.sendEmptyMessage(0);

2日更多钞票的解决方案是：

2nd Posible Solution is :

把你的方法调用code内的以下内容：

put your method calling code inside the following:

runOnUiThread(new Runnable(){

public void run(){

//Call the method here
}

});

希望这有助于
