Note that this requires that the root view 21 implements the Checkable interface. Once the root view is checked, any children that 22 have the duplicateParentState attribute set will inherit this "checked" state. 23 --> 24 <com.example.android.customchoicelist.CheckableLinearLayout 25 xmlns:android="http://schemas.android.com/apk/res/android" 26 android:orientation="horizontal" 27 android:layout_width="match_parent" 28 android:layout_height="match_parent" 29 android:paddingLeft="8dp" 30 android:paddingRight="8dp" 31 android:minHeight="?android:listPreferredItemHeight" 32 android:gravity="center_vertical"> 33 34 <!-- 35 The duplicateParentState attribute on this TextView, along with the color state list 36 used in the textColor attribute causes its text color to change when its parent 37 is checked or unchecked. 38 --> 39 <TextView android:id="@android:id/text1" 40 android:duplicateParentState="true" 41 android:layout_width="0dp" 42 android:layout_weight="1" 43 android:layout_height="wrap_content" 44 android:textAppearance="?android:textAppearanceMedium" 45 android:textColor="@color/hideable_text_color" /> 46 47 <!-- 48 The duplicateParentState attribute on this ImageView, along with the state list 49 drawable in the src attribute causes its image to change when its parent 50 is checked or unchecked. 51 52 To use the standard radio or checkmark image, set the src to 53 ?android:listChoiceIndicatorMultiple or ?android:listChoiceIndicatorSingle. These 54 are system theme attributes that reference a state list drawable. 55 --> 56 <ImageView android:src="@drawable/ic_hideable_item" 57 android:duplicateParentState="true" 58 android:layout_width="wrap_content" 59 android:layout_height="wrap_content" 60 android:layout_marginLeft="16dp" /> 61 62 </com.example.android.customchoicelist.CheckableLinearLayout> 63
