關於ScrollView巢狀ExpandableListView導致ExpandableListView顯示不正常的問題解決方法有很多,在這裡介紹一種小編親自測試通過的方法。
重寫ExpandableListView:
package com.jph.view; import android.content.Context; import android.util.AttributeSet; import android.widget.ExpandableListView; /** * 重寫ExpandableListView以解決ScrollView巢狀ExpandableListView *<br> 導致ExpandableListView顯示不正常的問題 * @author jph * Date:2014.10.21 */ public class CustomExpandableListView extends ExpandableListView { public CustomExpandableListView(Context context) { super(context); // TODO Auto-generated constructor stub } public CustomExpandableListView(Context context, AttributeSet attrs) { super(context, attrs); // TODO Auto-generated constructor stub } public CustomExpandableListView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); // TODO Auto-generated constructor stub } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { // TODO Auto-generated method stub int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST); super.onMeasure(widthMeasureSpec, expandSpec); } }
在XML中將ExpandableListView替換為重寫的ExpandableListView即可。
<com.jph.view.CustomExpandableListView android:id="@+id/elItems"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
