如何隐藏查看编程？ [英] How to hide a View programmatically?

问题描述

在我的应用程序，我有2 的LinearLayout 的上述对方的权利。通过菜单选项，我希望能够做一个底部消失，并在顶部有一个下拉消失的LinearLayout 。

In my application, I have 2 LinearLayout's right above each other. Via a menu option, I want to be able to make the bottom one disappear, and have the top one drop down over the disappeared LinearLayout.

现在的问题是，我不知道如何做到这一点的Java。

The problem is, I have no idea on how to do this in Java.

这并不一定是动画，我想隐藏布局返回上另一个活动（菜单），在 OnActivityResult 。菜单活动设置一个布尔上，我检查 OnActivityResult ，并根据它的值，我确定我是否需要隐藏或显示底部布局：

It doesn't have to be animated, I want to hide the Layout on return of another activity (the menu), in OnActivityResult. The menu activity sets a boolean on which I check in OnActivityResult, and according to it's value I determine if I need to hide or show the bottom Layout:

// Only change value if it is different from what it was.
if(mUseVolumeButtonAsPTT != resultData.getBoolean("UseVolumeButtonAsPTT")){
    mUseVolumeButtonAsPTT = resultData.getBoolean("UseVolumeButtonAsPTT");
    if(!mUseVolumeButtonAsPTT){
        // Hide lower LinearLayout.
    } else {
        // Show lower LinearLayout.
    }
}

谁能给我，我应该怎么办这个问题的提示或链接？

Can anybody give me a hint or a link on how I should do this?

推荐答案

您可以致电 view.setVisibility（View.GONE）如果您想从布局中删除或 view.setVisibility（View.INVISIBLE）如果你只想隐藏它。

You can call view.setVisibility(View.GONE) if you want to remove it from the layout, or view.setVisibility(View.INVISIBLE) if you just want to hide it.
