被翻译，缩放或旋转子视图消失 [英] Child Views that are translated, scaled or rotated disappear

问题描述

我有一个的ViewGroup 和我添加子视图，以这样的：

I have a ViewGroup and I'm adding child Views to it like this:

mViewGroup.addView(view, new LayoutParams(LayoutParams.WRAP_CONTENT,
                LayoutParams.WRAP_CONTENT));

（即 WRAP_CONTENT 是 onclicklistener 按预期方式工作很重要）。

(the WRAP_CONTENT is important for the onclicklistener to work as expected).

到目前为止好，但后来我周围的动态通过重写他们的的onDraw 方法或通过覆盖ViewGroups移动子视图：

So far so good, but later I move the child Views around dynamically by either overriding their onDraw methods or by overriding the ViewGroups:

protected boolean getChildStaticTransformation(View child, Transformation t)

的问题是，在儿童中消失，如果他们似乎当它们首先被添加到计算其原始区域的外侧移动。我打过电话 setClipChildren（假）; ，但没有奏效。

我可以通过解决问题添加儿童在 LayoutParams.FILL_PARENT 的意见，但在这种情况下， onClickListener 将任何反应，点击整体上的ViewGroup ，我希望它只是点击反应在哪里我的孩子转变查看所在的特定区域。

I could solve the problem by using LayoutParams.FILL_PARENT when adding the child views but in this case the onClickListener would react to any click on the whole ViewGroup and I want it to only react to clicks on the specific area where my transformed child View is located.

也许我仍然可以使用 LayoutParams.FILL_PARENT 如果有一种方法来定义的查看可点击区域应该的。

Maybe I could still use LayoutParams.FILL_PARENT if there is a way to define where the clickable region for the View should be.

有什么建议？

推荐答案

也许你应该与你的孩子的意见边距和补实验。否则，你可以尝试使用不同的ViewGroup布局一样可以看到每个角度的现在的位置是可以通过其边距设置的FrameLayout。

Perhaps you should experiment with margins and paddings of your child views. Otherwise you could try to use a different ViewGroup layout like a FrameLayout where the postion of each view can be set by its margins.
