我需要与 IOS 开发人员合作。他不知道 Android 在布局系统中是如何工作的。他设计了一个非常动态的 UI。请看我的链接。

备注：橙色矩形表示图像按钮。
在此布局中，存在两个主要视图。对于视图 1，它是一个列表视图。单击一个项目时，视图 2 将动画化。视图 2 从右向左移动。此外，它稍微覆盖了 View 1。翻译完成后，橙色 Rect 也会动画。它们从底部移动到相对位置。
我跟他们说话。如果我做那个设计，布局就不能重复使用。其次，我不想为播放动画和 UI 设计硬编码。
他们认为一切皆有可能，而且很容易做到 = =|||。
如果你是我，你会怎么设计？
这是我的解决方案，但视图 2 无法覆盖视图 1。
public class EducationSystemActivity extends Activity
{
ImageButton mButton1 = null;
ImageButton mButton2 = null;
ImageButton mButton3 = null;
ImageButton mButton4 = null;
ImageButton mButton5 = null;
OnClickListener mImageButtonClickListner = new OnClickListener()
{
@Override
public void onClick(View v)
{
switch(v.getId()){
case R.id.imageButton1:{
Fragment fragment = new TestFragment2();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.animator.fragment_slide_left_enter,
R.animator.fragment_slide_left_exit,
R.animator.fragment_slide_right_enter,
R.animator.fragment_slide_right_exit);
ft.replace(R.id.fragment_content, fragment);
ft.addToBackStack(null);
ft.commit();
Toast.makeText(EducationSystemActivity.this, "Button1", Toast.LENGTH_SHORT).show();
break;
}
case R.id.imageButton2:{
Toast.makeText(EducationSystemActivity.this, "Button2", Toast.LENGTH_SHORT).show();
