附加到父 (RelativeLayout) 布局时动画不起作用？

Question

我尝试将按钮从顶部动画化到屏幕上的固定位置，当在按钮上添加 clicklistener 时它起作用了，但在附加到 relativelayout 时它不起作用。这样包含相对布局的按钮就会动画化。我认为问题是在嵌套视图组中附加布局时，请帮我解决问题。提前致谢。

 b = (Button) findViewById(R.id.simpleButton);
    relativeLayout = (RelativeLayout) findViewById(R.id.wrapper);
    b.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            b.startAnimation(animations());
        }
    });
    relativeLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            relativeLayout.setAnimation(animations());
        }
    });
}


private TranslateAnimation animations() {
    TranslateAnimation translateAnimation = new TranslateAnimation(0f, 0f, 0, -40);
    translateAnimation.setDuration(1000);
    translateAnimation.setInterpolator(new AccelerateInterpolator());
    return translateAnimation;
}

这里是 XML;

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
     <RelativeLayout
android:id="@+id/wrapper"
android:layout_width="match_parent"
android:background="#cbcbbc"
android:layout_height="60dp">
    <Button
        android:id="@+id/simpleButton"
        android:layout_width="wrap_content"
        android:layout_height="40dp"
        android:text="Go next page" />
   </RelativeLayout>

   </LinearLayout>

Answer 1

将此添加到 RelativeLayout：

android:clickable="true"

而不是：

relativeLayout.setAnimation(animations());

这样做：

relativeLayout.startAnimation(animations());

Animation doesn't work when attached to the parent (RelativeLayout)layout?
