ViewGroup setVisibility 为GONE 子View依然占用地方,其中的子EditText会出现点击焦点占用

首先，要实现的效果图如下，点击注册按钮后，进行登录表单0~90度旋转，然后注册表单-90度旋转至0度，最终实现两者的切换，但是遇到了一点问题，记录下来，以后忘记了做个参考。



使用LinearLayout 包裹着EditText,发现很多奇怪的现象

1.LinearLayout  对象 afterView.setVisibility(View.GONE);

2.然后切换回第二块LinearLayout   布局

发现原来的1步的LinearLayout  的子View EditText控件，依然会占用地方，焦点点击软键盘可以弹出，可是输入的内容，是显示在已经隐藏了的1步

LinearLayout  中的EditText输入框中的

经过一番思考和查找资料，发现，这个问题得这么解决

---------------/**切换显示**/
afterView.setVisibility(View.VISIBLE);
for ( int i=0 ; i<afterView.getChildCount() ; i++ ) {
/**让viewgroup隐藏还不行，子view还是占用了地方，
* 点击焦点还是会选中，得一口气把所以子view
* 包括 viewgroup 都隐藏掉**/
afterView.getChildAt(i).setVisibility(View.VISIBLE);
}
currentView.setVisibility(View.GONE);
for ( int i=0 ; i<currentView.getChildCount() ; i++ ) {
/**让viewgroup隐藏还不行，子view还是占用了地方，
* 点击焦点还是会选中，得一口气把所以子view
* 包括 viewgroup 都隐藏掉**/
currentView.getChildAt(i).setVisibility(View.GONE);
}
