Android: how to make a GroupBox widget?

问题

It appears that Android doesn't offer such a useful widget. However, my screen design requires a view like this:

Also, the interaction design requires that such boxes are displayed and hidden, depending on other data.

Of course, I could construct such box from separate elements in my XML layout (e.g. from a shape and a textview over it), but then managing their visibility turns into hell...

So it's clear that what is needed here is a container, like a relative layout. Such container can have children in XML layout and can be shown and hidden with a simple setVisibility(...) call.

Can someone give me a tip how to do that, please?

I don't think there is one, but I hacked together soemthing manual...not the same I know, but thought I'd share "@drawable/divider" is a 2 pixel square grey image. Creates the illusiuon of a box around the controls.

回答2:

Keep this in your Drawable file name "selector_fieldset_background.xml"

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
    <solid android:color="#FFFFFF" />
    <stroke
      android:width="1dip"
      android:color="#4fa5d5" />
</shape>

And this in you layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

  <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_marginTop="13dp"
    android:background="@drawable/selector_fieldset_background"
    android:orientation="vertical" >
  </LinearLayout>

  <TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:background="@color/white"
    android:paddingLeft="20dp"
    android:paddingRight="20dp"
    android:text="Order Information"
    android:textAppearance="?android:attr/textAppearanceLarge"/>
</RelativeLayout>

This will create a Group box Component as shown in your image.
