PopupWindow+ListView

Posted 2020-07-22 碎冰

1. 获取打到数据

for (int i = 0; i < iocOutMakeMaterialSubmit.data.size(); i++) {
    dataListPopupWindow.add(iocOutMakeMaterialSubmit.data.get(i));
}
initPopupWindow();

2. 初始化

/**
 * 创建PopupWindow
 */
protected void initPopupWindow() {
    LayoutInflater inflater = LayoutInflater.from(getActivity());
    View contentView = inflater.inflate(R.layout.popupwindow_ioc_out_make_material_submit, null);
    ListView listView = (ListView) contentView.findViewById(R.id.list_view_submit_popwin);
    adapterPopupwindow = new AdapterPopupWindow(getActivity(), R.layout.item_list_ioc_out_make_material_submit, dataListPopupWindow);
    listView.setAdapter(adapterPopupwindow);
    //item 的点击事件
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            IOCOutMakeMaterialSubmit.Data data = dataListPopupWindow.get(i);
            dataList.add(data);
            adapterListView.notifyDataSetChanged();
            closePopupWindow();
            reset();
        }
    });
    // PopupWindow实例化
    popupWindow = new PopupWindow(contentView, LinearLayout.LayoutParams.MATCH_PARENT,
            LinearLayout.LayoutParams.MATCH_PARENT, true);
    popupWindow.setAnimationStyle(R.style.MenuAnimationFade);
    // 弹出窗口显示内容视图,默认以锚定视图的左下角为起点，这里为点击按钮
    popupWindow.showAtLocation(submitBtn, Gravity.CENTER, 0, 0);
    //获取最底层窗口的参数，背景变灰色效果
    WindowManager.LayoutParams params = getActivity().getWindow().getAttributes();
    params.alpha = 0.5f;
    getActivity().getWindow().setAttributes(params);
}

3.关闭窗口

/**
 * 关闭窗口
 */
private void closePopupWindow() {
    if (popupWindow != null && popupWindow.isShowing()) {
        popupWindow.dismiss();
        popupWindow = null;
        WindowManager.LayoutParams params = getActivity().getWindow().getAttributes();
        params.alpha = 1f;
        getActivity().getWindow().setAttributes(params);
    }
}
