Question

我在GroupView的ExpandableListView中设置TextView的宽度时遇到问题。此ExpandableListView位于滑动菜单中。菜单第一次滑动时，GroupView如下所示：

但是当我们点击一些选项时，它看起来像这样：

这是正确的观点，我每次都喜欢这种观点，而不仅仅是当我们点击某些群体选项时。我该如何修复这个错误？

这是我的源代码：

activity_main.xml中

  <ExpandableListView
        android:fillViewport="true"
        android:padding="20dp"
        android:id="@+id/lvExp"
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:groupIndicator="@null"
        android:choiceMode = "singleChoice"
        android:dividerHeight="10dp"
        android:divider="@color/blue"
        android:childDivider="@color/blue"
        android:background="@color/blue"
        android:layout_gravity="center_horizontal|center_vertical"
        />

expandable_list_group.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:paddingLeft="10dp"
    android:id="@+id/ll"
    android:paddingRight="10dp"
    android:paddingTop="10dp"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/blue"
    android:fillViewport="true"
    android:gravity="center_horizontal|center_vertical"
    >

    <TextView
        android:fillViewport="true"
        android:background="@drawable/expandable_list_item_background"
        android:id="@+id/lblListHeader"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:textSize="17dp"
        android:textColor="@drawable/list_item_text_selector"
        android:gravity="center_horizontal|center_vertical"
        />

</LinearLayout>

expandable_list_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:paddingLeft="40dp"
    android:paddingRight="40dp"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/blue"
    android:gravity="center_horizontal|center_vertical"
    >

    <TextView
        android:background="@drawable/button_shape"
        android:id="@+id/label"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:textSize="17dp"
        android:textColor="@drawable/list_item_text_selector"
        android:gravity="center_horizontal|center_vertical"
        />

</LinearLayout>

MainLayout.java（设置幻灯片菜单宽度的方法）

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    mainLayoutWidth = MeasureSpec.getSize(widthMeasureSpec);
    menuRightMargin = mainLayoutWidth * 20 / 100;
}
