PopupWindow 用法 PopupWindow不消失 解决方法

PopupWindow创建

popupWindow = new PopupWindow(getLayoutInflater().inflate(R.layout.newpopupwindow, null),300,300);
		popupWindow.setFocusable(true);
		popupWindow.setBackgroundDrawable(Test.this.getResources().getDrawable(R.drawable.ic_launcher));
		popupWindow.setOutsideTouchable(true);
		popupWindow.showAsDropDown(v, 0,0);

其中

</pre><pre name="code" class="html">popupWindow = new PopupWindow(getLayoutInflater().inflate(R.layout.newpopupwindow, null),300,300);
<pre name="code" class="html">popupWindow = new PopupWindow(getLayoutInflater().inflate(R.layout.newpopupwindow, null),300,300,true);
<pre name="code" class="html">popupWindow = new PopupWindow(getLayoutInflater().inflate(R.layout.newpopupwindow, null),300,300，false);

这三者没区别

API解释为 <span style="font-family: Arial, Helvetica, sans-serif;">A popup window that can be used to display an arbitrary view. The popup window is a floating container that appears on top of the current activity.</span>

其中new PopupWindow 中的第一个参数为自定义的view 后面两个分别为PopupWindow宽和高

.setFocusable() 设置PopupWindow 是不是能接受焦点

.setoutsideTouchable PopupWindow外面能不能点击 点击之后会使PopupWindow 消失 dismiss()

showASDropDown 显示的方式

假如设置了 setBackgroundDrawable 就算没有设置 .setoutsideTouchable 也可以点击popupwindow之外的地方使popupwindow消失

只设置了 setfocusable 而没设置 setbackgroundDrawable 点击Popupwindow 之外的地方 popupwindow不消失

PopupWindow 无法消失的情况 解决方法：

1.只设置了 setfocusable 而没设置 setbackgroundDrawable 点击Popupwindow 之外的地方 popupwindow不消失

2.showAsDropDown 在PopWindow设置完setbackgrounddrawable之前就已经执行了
