Android——Popwindow从底部弹出

1、设置代码

public void ShowPopWindow(View view) {
        PopupWindow pop = new PopupWindow(width, height / 4);
        pop.setOutsideTouchable(true);
        View v = getLayoutInflater().inflate(R.layout.popwin, null);
        TextView save = (TextView) v.findViewById(R.id.pop_save);
        save.setOnClickListener(this);
        pop.setBackgroundDrawable(getResources().getDrawable(R.color.white));
        pop.setAnimationStyle(R.style.popwin_anim_style);
        pop.setContentView(v);
        pop.setFocusable(true);
        pop.showAsDropDown(view);
    }

2、style设置

动画可以由自己设置，Y从100%p到0.
