/**
* 弹框
*/
private View mPopupHeadViewy;//创建一个view
private PopupWindow mHeadPopupclly;//PopupWindow
private TextView tetle, textdz;//title,打折
private TextView textwzdl, textckxq;//我知道了,查看详情

@SuppressWarnings("deprecation")
private void popupHeadWindowcll() {
mPopupHeadViewy = View.inflate(getActivity(), R.layout.tankuang_layout, null);
tetle = (TextView) mPopupHeadViewy.findViewById(R.id.tetle);
textdz = (TextView) mPopupHeadViewy.findViewById(R.id.textdz);
textwzdl = (TextView) mPopupHeadViewy.findViewById(R.id.textwzdl);
textckxq = (TextView) mPopupHeadViewy.findViewById(R.id.textckxq);
mHeadPopupclly = new PopupWindow(mPopupHeadViewy, AbsListView.LayoutParams.MATCH_PARENT, AbsListView.LayoutParams.MATCH_PARENT, true);
// 在PopupWindow里面就加上下面代码，让键盘弹出时，不会挡住pop窗口。
mHeadPopupclly.setInputMethodMode(PopupWindow.INPUT_METHOD_NEEDED);
mHeadPopupclly.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
mHeadPopupclly.setBackgroundDrawable(new BitmapDrawable());
mHeadPopupclly.setOutsideTouchable(true);
mHeadPopupclly.showAsDropDown(textviewid, 0, 0);
textwzdl.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mHeadPopupclly.dismiss();
}
});
textckxq.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mHeadPopupclly.dismiss();
Toast.makeText(getActivity(), "查看详情", Toast.LENGTH_LONG).show();
}
});
}

1、

mHeadPopupclly = new PopupWindow(mPopupHeadViewy, AbsListView.LayoutParams.MATCH_PARENT, AbsListView.LayoutParams.MATCH_PARENT, true);

这句代码就是控制弹出框是铺满屏幕还是自适应、

2、

mHeadPopupclly.showAsDropDown(textviewid, 0, 0);

这是一个简单的自定义弹框，大神勿喷，有用的希望顶一下、、、
