popupWindow.dismiss();// 关闭
}
}
}
/** 返回网格布局的适配器 */

List<HashMap<String, Object>> data = new ArrayList<HashMap<String, Object>>();
for (int i = 0; i < names.length; i++) {
HashMap<String, Object> item = new HashMap<String, Object>();
item.put("name", names[i]);
data.add(item);
}
SimpleAdapter simpleAdapter = new SimpleAdapter(this, data,
R.layout.menu_item, new String[] { "name" },
new int[] { R.id.textView });
return simpleAdapter;
}
public void openPopWindow(View v) {
/** 设置PopupWindow弹出后的位置 */
//popupWindow.showAtLocation(parent, Gravity.BOTTOM, 0, 0);
int[] location = new int[2];
v.getLocationOnScreen(location);
Log.v("li","按钮的位置："+location[0]+","+location[1]);
//popupWindow.showAsDropDown(v);
int w = location[0]-10;
//popupWindow.getHeight()
int h = location[1]+70;
Log.v("li","popupwindow的位置："+w+","+h);
popupWindow.showAtLocation(v, Gravity.NO_GRAVITY, location[0] + 25, location[1] + 67);
}
}
