Android how to create popup window(Android如何创建弹出窗口)

问题描述

我需要创建一个带有按钮的弹出窗口和一个关闭弹出窗口的按钮.我找到了一些教程，但我不知道如何实现.

I need to create a popup window with buttons and a button that will close the popup. I found some tutorials but I couldn't find out how to do the implementation.

我想要做什么:单击一个操作按钮并显示弹出窗口，当我单击关闭按钮时，弹出窗口必须关闭.

What I want to do: Click an action button and the popup shows and when I click the the close button the popup window must close.

教程中有一个onCreate方法，我不明白它是怎么调用的.

There were an onCreate method in the tuorials and I didn't understand how is it called.

    chartContainer1.addView(mChart);
    btn_closepopup.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub

}
