示例1: setAdapterHeight
import android.widget.ListView; //导入方法依赖的package包/类
public static void setAdapterHeight(ListView listView){
android.widget.ListAdapter listAdapter = listView.getAdapter();//1、获取adapter
if (listAdapter == null) {
return;
}
int totalHeight = 0;
for (int i = 0,j =listAdapter.getCount(); i < j ; i++) { //2、算出没一个item高度总和
View listItem = listAdapter.getView(i , null, listView);
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params=listView.getLayoutParams();
params.height = totalHeight + listView.getPaddingBottom() //3、加上listview自身每行间距属性
+ listView.getPaddingTop()
+ (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);//4、重新设置高
}
示例2: canListViewScrollUp
import android.widget.ListView; //导入方法依赖的package包/类
/**
* Utility method to check whether a {@link ListView} can scroll up from it's current position.
* Handles platform version differences, providing backwards compatible functionality where
* needed.
*/

// For ICS and above we can call canScrollVertically() to determine this
return ViewCompat.canScrollVertically(listView, -1);
} else {
// Pre-ICS we need to manually check the first visible item and the child view's top
// value
return listView.getChildCount() > 0 &&
(listView.getFirstVisiblePosition() > 0
|| listView.getChildAt(0).getTop() < listView.getPaddingTop());
}
}
示例3: setListViewHeightBasedOnItems
import android.widget.ListView; //导入方法依赖的package包/类
public static boolean setListViewHeightBasedOnItems(ListView listView) {
