Android PopupWindow 点击外面取消实现代码
private void showPopupView()
{
if (mPopupWindow == null)
{
View view = getLayoutInflater().inflate(R.layout.newest_layout, null);
mPopupWindow = new PopupWindow(view, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
mPopupWindow.setFocusable(true);//需要设置为ture,表示可以聚焦
//需要设置背景,用物理键返回的时候
mPopupWindow.setBackgroundDrawable(new BitmapDrawable(getResources()));
mPopupWindow.setOutsideTouchable(true);
view.setOnTouchListener(new OnTouchListener()// 需要设置,点击之后取消popupview,即使点击外面,也可以捕获事件
{
public boolean onTouch(View v, MotionEvent event)
{
if (mPopupWindow.isShowing())
{
Trace.Log("-------------------onTouch------------");
mPopupWindow.dismiss();
}
return false;
}
});
}
if (mPopupWindow.isShowing())
{
mPopupWindow.dismiss();
}
else
{
View parent = findViewById(R.id.newest);
mPopupWindow.showAsDropDown(parent);// 显示再指定控件的下面
}
}
