Android OnClick主布局不工作，是因为MotionLayout吗？

Question

我希望能够在名为“rl”的根相对论上执行onClickListner。不，它不起作用，我怀疑这可能是因为我还是个孩子的时候。如何解决这个问题？

这是我迄今为止所做的，我的代码。

ShowNoteActivity.java

(...)

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {

        (...)

        RelativeLayout rl = findViewById(R.id.rl);
        rl.setOnClickListener(view -> {
            Toast.makeText(this, "abc", Toast.LENGTH_SHORT).show();
        });
}

Answer 1

如果你想点击父项，你应该禁用motionlayout转换，用一个按钮或。。。禁用运动布局：

motionLayout.getTransition(R.id.yourTransition).setEnable(false)

如果必须在项目中使用onSwipe，则可以在折叠motionlayout后禁用转换，并以编程方式将布局返回顶部，然后在展开时启用motionlayout转换。
