Question

I have an XML layout for a view representing one item as displayed by a ExpandableListAdapter. (The XML that is duplicated once for each list item, not the main activity layout). I initially tried a LinearLayout but this hid the final of the three widgets (a image button). I understand why that doesn’t work but I then tried a RelativeLayout but the text view does not show.

I’ll display the relative layout first along with a screenshot and also append my initial layout and screenshot at the bottom FWIW. Thanks for any help.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="55dip"
    android:orientation="horizontal" >
    <CheckBox
        android:id="@+id/chkParent"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:checked="false"/>
    <EditText
        android:id="@+id/edtParent"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_toLeftOf="@id/chkParent"
        android:textSize="17dip"
        android:inputType="text"
        android:hint="@string/strItem"/>
     <ImageButton
        android:id="@+id/btnExpand"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_toLeftOf="@id/edtParent"
        android:src="@drawable/dark_expand"
        android:clickable="true"
        android:hint="@string/strViewSubItems"
        android:contentDescription="@string/strViewSubItems"
        android:background="@null"/>  
 </RelativeLayout>

Original linear layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="55dip"
    android:orientation="horizontal" >
    <CheckBox
        android:id="@+id/chkParent"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:checked="false"/>
    <EditText
        android:id="@+id/edtParent"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textSize="17dip"
        android:inputType="text"
        android:hint="@string/strItem"/>
    <ImageButton
        android:id="@+id/btnExpand"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:src="@drawable/dark_expand"
        android:clickable="true"
        android:hint="@string/strViewSubItems"
        android:contentDescription="@string/strViewSubItems"
        android:background="@null"/>  
 </LinearLayout>

Answer 1

Pretty sure your toLeftOf attributes should be toRightOf attributes. Give that a shot and see what happens.

Actually, your EditText should be set toRightOf="@id/chkParent" and toLeftOf="@id/btnExpand. Your ImageButton doesn’t even need the toRightOf modifier, the alignParentRight attribute should cover it.
