单击 FloatingActionButton 时如何显示 TextInputLayout EditText

Question

我已经浪费了好几个小时试图让它工作，但我做不到！

我在 Android Studio 中使用“导航抽屉”从头创建了一个项目

当用户单击FloatingActionButton 时，我需要显示一个如下图所示的文本框，当我再次单击FloatingActionButton 以将文本发送到我的服务时。

Java

  FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        //TextDrawable trxtDrawable = new TextDrawable("AB");
        //fab.setImageDrawable(trxtDrawable);

        textinput = (TextInputLayout) findViewById(R.id.textinput);
        busca = (EditText) findViewById(R.id.busca);

        textinput.setVisibility(View.GONE);
        busca.setVisibility(View.GONE);

        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //frameLayout.setVisibility(View.VISIBLE);
                textinput.setVisibility(View.VISIBLE);
                busca.setVisibility(View.VISIBLE);
            }
        });

为你的edittextTextInputLayout设置id

   fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                fab.setVisibility(View.Gone);
                textinput.setVisibility(View.VISIBLE);
                busca.setVisibility(View.VISIBLE);
            }
        });
