在ConstraintLayout中以编程方式删除/添加约束

我没有完成您的代码,但以下说明了如何使用中断和约束ConstraintSet.

    ConstraintSet set = new ConstraintSet();
    ConstraintLayout layout;

    layout = (ConstraintLayout) findViewById(R.id.layout);
    set.clone(layout);
    // The following breaks the connection.
    set.clear(R.id.bottomText, ConstraintSet.TOP);
    // Comment out line above and uncomment line below to make the connection.
    // set.connect(R.id.bottomText, ConstraintSet.TOP, R.id.imageView, ConstraintSet.BOTTOM, 0);
    set.applyTo(layout);
