如何把向上或向下编程一个看法？ [英] How to put up or down a view programatically?

问题描述

我有一个XML的基本骨架是

I have a xml that the basic "skeleton" is

<RelativeLayout>
    <FrameLayout>
        <RelativeLayout>
            <TextView>
            </TextView>
            <TextView>
            </TextView>
        </RelativeLayout>
        <DrawView>
            //The view that changes 1
        </DrawVIew>
        <EditText>
            //The view that changes 2
        </EditText>
    </FrameLayout>
    <RelativeLayout>
    </RelativeLayout>
</RelativeLayout>

我要的是，使用code中的DrawView上升或下降，所以有时你可以使用DrawView而在其他时刻，你可以使用的EditText，但有史以来两个视图显示。

What I want is that using code the DrawView goes up or down, so sometimes you can use the DrawView and in other moments you can use the EditText, but ever the two views are showed.

我怎么能这样做？

推荐答案

既然你都放置一个小工具里面的FrameLayout你可以改变它的引力象下面这样：

Since you are placing both widgets inside a FrameLayout you can change its gravity like below:

FrameLayout.LayoutParams drawViewLayoutParams = drawView.getLayoutParams();
drawViewLayoutParams.gravity = Gravity.BOTTOM;

FrameLayout.LayoutParams editTextLayoutParams = editText.getLayoutParams();
editTextLayoutParams.gravity = Gravity.TOP;
