查了查大部分有两个方法

方法1：

protected void showPopupWindow() {//Context mContext = HahItemActivity.this;LayoutInflater mLayoutInflater = (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);//保存转发等视图View xuanz_popunwindwow = mLayoutInflater.inflate(R.layout.popwindow_image, null);//转化为popunwindowmPopupWindow= new PopupWindow(xuanz_popunwindwow,LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);mPopupWindow.setBackgroundDrawable(new BitmapDrawable());   mPopupWindow.setFocusable(true);mPopupWindow.setOutsideTouchable(true);mPopupWindow.update();//设置显示mPopupWindow.showAtLocation(findViewById(R.id.hahaimage_pop_layout), Gravity.CENTER, 0,0);

//设置显示mPopupWindow.showAtLocation(findViewById(R.id.hahaimage_pop_layout), Gravity.CENTER, 0,0);

mPopupWindow.setBackgroundDrawable(new BitmapDrawable());   //!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!mPopupWindow.setFocusable(true);//!获取焦点!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1mPopupWindow.setOutsideTouchable(true);mPopupWindow.update();//!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

上面这三个语句就可以控制啦点击别的地方消失啦，要写在ShowAtLocation之前.()设置popupWindow.setFocusable(true); 这样才能让popupWindow里面的布局控件获得点击的事件否则就被它的父亲view给拦截了。

方法2 ：（这种方法可以处理popupwindows dimiss的时候一些其他的操作，比如让其他控件的隐藏，消失等）:
代码如下popupWindow.setFocusable(false);//focusable要为false(不设置默认的就是False)；
//这是Activity 的OnTouchEvent。OnTouchEvent代表的是Activity 获得事件（即为PopupWindow之外）
@Override
public boolean onTouchEvent(MotionEvent event) {
// TODO Auto-generated method stub
if (popupWindow != null && popupWindow.isShowing()) {
popupWindow.dismiss();
popupWindow = null;
}
return super.onTouchEvent(event);
}

注：亲测1可行
