简单实现PopupWindow弹出框

[blackberry]代码库

//在任何一个点击监听里写
public void showPopupWindow(String name){
        //找到popupWindow自定义的布局
        View popView = View.inflate(MainActivity.this, R.layout.pop_window, null);

        TextView pop_tv = (TextView) popView.findViewById(R.id.pop_tv);
        TextView nage_tv = (TextView) popView.findViewById(R.id.nage_tv);
        TextView posi_tv = (TextView) popView.findViewById(R.id.posi_tv);
        //给控件赋值
        pop_tv.setText(name);
        //new一个popupWindow,并且设置背景、点击外部是否dismiss、设置焦点、show进行展示
        final PopupWindow popupWindow = new PopupWindow(popView, 300, 300);
        popupWindow.setBackgroundDrawable(new ColorDrawable(Color.WHITE));
        popupWindow.setOutsideTouchable(false);//点击其他地方可以disimis
        popupWindow.setFocusable(true);//设置焦点可获取焦点
        popupWindow.showAtLocation(popView, Gravity.CENTER,0,0);//showAsDropDown(view);
        //控件监听进行dismiss
        posi_tv.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                popupWindow.dismiss();
            }
        });
    }
