示例1: canAdapterViewScroll
import android.widget.AdapterView; //導入方法依賴的package包/類
private static boolean canAdapterViewScroll(AdapterView lv) {
/* Force it to layout it's children */
if (lv.getLastVisiblePosition() == -1)
return false;
/* We can scroll if the first or last item is not visible */
boolean firstItemVisible = lv.getFirstVisiblePosition() == 0;
boolean lastItemVisible = lv.getLastVisiblePosition() == lv.getCount() - 1;
if (firstItemVisible && lastItemVisible && lv.getChildCount() > 0) {
/* Or the first item's top is above or own top */
if (lv.getChildAt(0).getTop() < lv.getPaddingTop())
return true;
/* or the last item's bottom is beyond our own bottom */
return lv.getChildAt(lv.getChildCount() - 1).getBottom() >
lv.getHeight() - lv.getPaddingBottom();
}
return true;
}
示例2: onItemClick
import android.widget.AdapterView; //導入方法依賴的package包/類
@Override
public void onItemClick(AdapterView<?> adapter, View view, int pos, long id) {
// Log.d("log:", String.format("pos:%d", pos));
