重写ListView：
package com.example.test;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.ListView;
public class NoScrollListView extends ListView{
public NoScrollListView(Context context, AttributeSet attrs){
super(context, attrs);
}
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
int mExpandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, mExpandSpec);
}
}
public class Utility {
public static void setListViewHeightBasedOnChildren(ListView listView) {
//获取ListView对应的Adapter
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
// pre-condition 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.getDividerHeight()获取子项间分隔符占用的高度
//params.height最后得到整个ListView完整显示需要的高度 listView.setLayoutParams(params);
}
}
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_MOVE) {
scrollView.requestDisallowInterceptTouchEvent(true);
}
return false;
}
});
