单击FloatingActionButton时如何显示TextInputLayout EditText

问题描述

我浪费了很多时间试图使它起作用，但我做不到！

I've wasted hours trying to make it work and I can not do it!

我在Android Studio中使用导航抽屉"从头开始创建了一个项目

I created a project from scratch in Android Studio with "Navigation drawer"

当用户单击FloatingActionButton时，我需要在下图显示一个文本框，当我再次单击FloatingActionButton将文本发送到我的服务时.

When the user clicks on the FloatingActionButton, I need to show a text box as this image below and when I click on the FloatingActionButton again to send the text to my service.

此处为图片

我的app_bar_main.xml

Java

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

        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);
            }
        });

推荐答案

为您的edittext TextInputLayout

Set id for your edittextTextInputLayout

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