我浪费时间试图让它发挥作用而我无法做到!
我在Android Studio中用“导航抽屉”
从零开始创建了一个项目当用户点击FloatingActionButton
时,我需要在下方显示一个文本框,当我再次点击FloatingActionButton
将文字发送到我的服务时。

爪哇
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);
}
});
答案 0 :(得分:0)
为您的edittext TextInputLayout
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
fab.setVisibility(View.Gone);
textinput.setVisibility(View.VISIBLE);
busca.setVisibility(View.VISIBLE);
}
});
