在customView

Question

我有以下情况：

• 主要Customview（绿色和蓝色圆圈，仅用于演示）
• 一个Web视图，它显示在主自定义视图（视图组）的顶部

这是可行的，但也许这是一个hack（请参见下面的代码）

我想做什么：

单击主Customview时，无法更改Web视图的位置和大小。

代码：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    getSupportActionBar().hide();

    ConstraintLayout constraintLayout = new ConstraintLayout(this);

    MainCustomView mainCustomView = new MainCustomView(this);
    mainCustomView.setId(View.generateViewId());
    constraintLayout.addView(mainCustomView);
    mainCustomView.setLayoutParams(new ConstraintLayout.LayoutParams(ConstraintLayout.LayoutParams.MATCH_PARENT, ConstraintLayout.LayoutParams.MATCH_PARENT));

    final SubCustomView subCustomView = new SubCustomView(this);

    subCustomView.setLayoutParams(new ViewGroup.LayoutParams(BOX_WIDTH, BOX_HEIGHT));
    subCustomView.setId(View.generateViewId());

    constraintLayout.addView(subCustomView);
    ConstraintSet constraintSet = new ConstraintSet();
    constraintSet.clone(constraintLayout);
    constraintSet.connect(subCustomView.getId(), ConstraintSet.TOP, ConstraintSet.PARENT_ID, ConstraintSet.TOP, BOX_TOPMARGIN);
    constraintSet.connect(subCustomView.getId(), ConstraintSet.LEFT, ConstraintSet.PARENT_ID, ConstraintSet.LEFT, BOX_LEFTMARGIN);
    constraintLayout.setConstraintSet(constraintSet);
    subCustomView.loadData(getBeforeClickText(), "text/html", "UTF-8");

    mainCustomView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            subCustomView.loadData(getAfterClickText(), "text/html", "UTF-8");
            <<<<<<<<<<< New POSITION and SIZE of the Webview >>>>>>>>>>>
        }
    });
    setContentView(constraintLayout);
}

问题： 我怎样才能做到这一点 ？是我以正确的方式开始的方法，还是在动态显示和更改Webview以及与其交互时是否有更好的解决方案？也许使用ViewOverlay？
