解决ScrollView嵌到listView冲突问题

时间:2021-11-12 05:05:25

方法一:

把下面的方法放在绑定适配器操作的下面就行。

/**
* 重新计算ListView的高度,解决ScrollView和ListView两个View都有滚动的效果,在嵌套使用时起冲突的问题
* @param listView
*/
public void setListViewHeight(ListView listView) {

// 获取ListView对应的Adapter

ListAdapter listAdapter = listView.getAdapter();

if (listAdapter == null) {
return;
}
int totalHeight = 0;
for (int i = 0, len = listAdapter.getCount(); i < len; i++) { // listAdapter.getCount()返回数据项的数目
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(0, 0); // 计算子项View 的宽高
totalHeight += listItem.getMeasuredHeight(); // 统计所有子项的总高度
}

ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));

listView.setLayoutParams(params);
}

方法二:

重写listview

public class MyListView extends ListView {

    public MyListView(Context context) {
// TODO Auto-generated method stub
super(context);
} public MyListView(Context context, AttributeSet attrs) {
// TODO Auto-generated method stub
super(context, attrs);
} public MyListView(Context context, AttributeSet attrs, int defStyle) {
// TODO Auto-generated method stub
super(context, attrs, defStyle);
} @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);
}
}

注:

mYoujiLinearLayout = (LinearLayout) mFragmentView.findViewById(R.id.home_jinghuayouji_show_layout);

ListView外要套一个linearLayout布局mListView = (ListView) mYoujiLinearLayout.findViewById(R.id.home_jinghuayouji_show_layout_listview);

要不会开在自定义适配器getCount()这个方法不往下执行
