这可能有点长，但我会在解释时非常清楚。

我正在开发一个应用程序，它基本上由一个布局组成，有两个相对布局。当您单击两个布局中的任何一个时，第二个布局会根据其实际可见性进行扩展或缩小。

这是布局：

在此处输入图像描述

这是侦听任何单击“main”或“child”以展开/收缩的代码：

    public void toggleAmagar(View v){
        View parent = (View) v.getParent();
        View child = parent.findViewById(R.id.child);
        Log.d("debugging","toggle amagar. Child visibility is :"+child.getVisibility()+". Clickable? Child: "+child.isClickable()+". Parent: "+v.isClickable());
        ExpandAnimation expandAni = new ExpandAnimation(child, 500);
        child.startAnimation(expandAni);
    }

这是动画类：

public class ExpandAnimation extends Animation {
private View mAnimatedView;
private LayoutParams mViewLayoutParams;
private int mMarginStart, mMarginEnd;
private boolean mIsVisibleAfter = false;
private boolean mWasEndedAlready = false;

public ExpandAnimation(View view, int duration) {
    setDuration(duration);
    mAnimatedView = view;
    mViewLayoutParams = (LayoutParams) view.getLayoutParams();
    // decide to show or hide the view
    mIsVisibleAfter = (view.getVisibility() == View.VISIBLE);

    mMarginStart = mViewLayoutParams.bottomMargin;
    mMarginEnd = (mMarginStart == 0 ? (0- view.getHeight()) : 0);
    view.setVisibility(View.VISIBLE);
}

@Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
    super.applyTransformation(interpolatedTime, t);
    Log.d("debugging","aplicant. Visible = "+this.mAnimatedView.getVisibility());
    mAnimatedView.setClickable(false);
    if (this.hasEnded()){
        mAnimatedView.setClickable(true);
        View pare = (View) mAnimatedView.getParent();
        View germa = (View) pare.findViewById(R.id.main);
        germa.setClickable(true);
    } else {
        mAnimatedView.setClickable(false);
        View pare = (View) mAnimatedView.getParent();
        View germa = (View) pare.findViewById(R.id.main);
        germa.setClickable(false);
    }
    if (interpolatedTime < 1.0f) {

        // Calculating the new bottom margin, and setting it
        mViewLayoutParams.bottomMargin = mMarginStart
                + (int) ((mMarginEnd - mMarginStart) * interpolatedTime);

        // Invalidating the layout, making us seeing the changes we made
        mAnimatedView.requestLayout();

    // Making sure we didn't run the ending before (it happens!)
    } else if (!mWasEndedAlready) {
        mViewLayoutParams.bottomMargin = mMarginEnd;
        mAnimatedView.requestLayout();

        if (mIsVisibleAfter) {
            mAnimatedView.setVisibility(View.GONE);

        }
        mWasEndedAlready = true;
    }
}

这是在 Android 2.3 中发生的情况： 在此处输入图像描述

这些是生成的日志：

03-17 13:57:45.439: D/debugging(403): toggle amagar. Child visibility is :8. Clickable? Child: true. Parent: true

现在我也在做同样的事情，但在 4.2 中（4.0.4 真实设备的工作方式相同）： 在此处输入图像描述

如您所见，唯一的区别是第二次点击没有在 2.3 设备上应用动画。

我已经在具有 2.3 和其他 4.0.4 的真实设备上对其进行了测试，并且它也在发生。这些是虚拟化的。

如果您需要更多信息，请询问我。

哦，顺便说一下，Animation 类中的 setClickable() 技巧是为了防止用户双击动画和布局，以防万一你想知道它。

谢谢你。

编辑 尝试了几个 SDK：

  • 2.2 -> 错误
  • 2.3 -> 错误
  • 4.2 -> 好的
  • 4.0 -> 好的

编辑 19/03

更新：仍在发生，我不知道为什么。如果没有人找到答案，明天我将继续调试......谢谢。
