在两个视图之间定位imageView并动态调整其大小？

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button 1" />

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:src="@drawable/your_image" />

    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button 2"
        android:layout_below="@id/imageView" />

</RelativeLayout>

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    final ImageView imageView = findViewById(R.id.imageView);

    final ViewTreeObserver observer = imageView.getViewTreeObserver();
    observer.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            // 在布局变化时调整imageView的大小
            int width = imageView.getWidth();
            int height = imageView.getHeight();

            // 根据需要进行大小调整的逻辑

            // 移除监听器，避免重复调用
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                imageView.getViewTreeObserver().removeOnGlobalLayoutListener(this);
            } else {
                imageView.getViewTreeObserver().removeGlobalOnLayoutListener(this);
            }
        }
    });
}
