简单的底部菜单 类似微信订阅号里面的底部菜单

初次写博客，多多指点。

为以后用的时候准备一点

textview+popupwindow简单实现底部菜单

布局底部有三个TextView   点击后出现在上部popUpwindows

显示popUpwindows的代码

   DisplayMetrics metric = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(metric);
    int width = metric.widthPixels;
// TODO Auto-generated method stub
LayoutInflater inflater = (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
      View layout = inflater.inflate(R.layout.menu_hf, null);
PopupWindow pop = new PopupWindow(layout, LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT, true);
pop.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
pop.setFocusable(true);
pop.setOutsideTouchable(true);
pop.update();
pop.setBackgroundDrawable(new BitmapDrawable());
pop.showAtLocation(this.tv_hf, Gravity.BOTTOM|Gravity.CENTER_HORIZONTAL,-width/3,100); //设置layout在PopupWindow中显示的位置

弹出的popUpwindows是一个布局文件
