android - FloatingActionButton OnClickListener 不工作

Question

从来没有错误。但是，您可以在动画中看到它被点击了。从父 Activity 为 MyMainActivity 的子 Activity 调用 Java 代码。

我还将包括该项目的 github，以防有人想尝试它。

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fav_button);

    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Log.v("CLICKED","");
        }
    });

以编程方式将 FAB 置于最前面也应该可行:

FloatingActionButton fab = (FloatingActionButton) 
findViewById(R.id.fab);
fab.bringToFront();
fab.setOnClickListener... //etc
