在所有元素上设置 android:focusable="false" 。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:baselineAligned="false"
    android:paddingTop="5dip" 
    android:focusable="false">

    <LinearLayout
        android:id="@+id/groupItem"
        android:layout_width="0dip"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:background="#FFF385"
        android:clickable="false" 
        android:focusable="false">

        <TextView
            android:id="@+id/item_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="#FF84"
            android:clickable="false"
            android:focusable="false"
            android:focusableInTouchMode="false"
            android:text="sample"
            android:textColor="#000000"
            android:textSize="20sp" />

    </LinearLayout>

</LinearLayout>

不要忘记启用子 Selectable 属性..

@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
    // TODO Auto-generated method stub
    return true;
}

它也对我有用......布局中的所有项目（孩子的）必须设置为focusable =“false”和clickable =“false”。但是，如果您在子布局中有按钮，这将不起作用。
