Question

所以我的布局仍然可见，也许有人看到错误？我想在点击infoButton（imagebutton）时取消它。

<pre>
  <%= select_tag "sippeer_type", options_from_collection_for_select(@guest_server, "id", "name") %>
</pre>

我说：How to change visibility of layout programaticly

EDITED：错误的代码部分，仍然不适合我

*试试这个**

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.demo.MainActivity" >

<FrameLayout
    android:id="@+id/serviceLayout"
    android:layout_width="match_parent"
    android:layout_height="150dp"
    android:background="#000000" />

<Button
    android:id="@+id/btnHide"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:onClick="infoPressed"
    android:text="Hide" />

</RelativeLayout>

<强> MainActivity.java

public class MainActivity extends Activity
{

    FrameLayout infolayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        infolayout = (FrameLayout) findViewById(R.id.serviceLayout);
    }

    public void infoPressed(View v){ //info button is pressed by user
    //infoLayout.setVisibility(View.GONE); 

        infolayout.setVisibility(View.INVISIBLE);
    }


}

如果您的身份证明声明正确，我猜您必须更改行

infolayout.setVisibility(View.INVISIBLE);

到

infolayout.setVisibility(FrameLayout.INVISIBLE);

为什么布局不会变得不可见？
