（Android版）布局不会setVisibility（view.GONE）后重绘？ [英] (Android) Layout won't redraw after setVisibility(view.GONE)?

问题描述

在应用程序我有：
的LinearLayout linearLayout2 =（的LinearLayout）findViewById（R.id.cvLinearLayout2）;

In app I have: LinearLayout linearLayout2 = (LinearLayout) findViewById(R.id.cvLinearLayout2);

和之后：
linearLayout2.setVisibility（View.GONE）;

我不能找到一个办法让linearLayout2回??

Tryed一切：

                  linearLayout2.setVisibility(View.VISIBLE);
          linearLayout2.bringToFront();
          linearLayout2.getParent().requestLayout();
          linearLayout2.forceLayout();
          linearLayout2.requestLayout();
          linearLayout2.invalidate();

但没有结果。
linearLayout2有一个parrent linearLayout1，所以我也tryed：

but with no results. linearLayout2 have one parrent linearLayout1, so I tryed also:

                 linearLayout1.requestLayout();
          linearLayout1.invalidate();

仍然为零的结果，linearLayout2 stayes GONE？
我需要在我的应用程序移动的LinearLayout走，然后，过了一段时间再重新绘制。请帮助。

still with zero results, linearLayout2 stayes GONE ?? I need in my app to move linearLayout away, and then, after a while to redraw it again . Please help.

推荐答案

视图的可见性设置为GONE应该不会影响它的通过使用方法setVisibility（View.VISIBLE）回来的能力。

Setting a View's visibility to GONE should not affect it's ability to "come back" by using the method setVisibility(View.VISIBLE)

例如我有这样的code在我的应用程序之一：

For example I have this code in one of my apps:

public void onCheckedChanged(CompoundButton checkBox, boolean isChecked{
    if(checkBox == usesLocationCheckBox)
    {
        View view = findViewById(R.id.eventLocationOptions);
        if(isChecked)
        {
            view.setVisibility(View.VISIBLE);
            usesTimeCheckBox.setEnabled(false);
        }
        if(!isChecked)
        {
            view.setVisibility(View.GONE);
            usesTimeCheckBox.setEnabled(true);
        }
    }}

和它完美的罚款。其他一些code你的程序执行必须负责。编辑您的帖子相关code和我们或许可以给你一个更好的答案。

And it works perfectly fine. Some other code your program is executing must be responsible. Edit your post with the relevant code, and we may be able to give you a better answer.
