我有一个动态显示数据的自定义 GridView。数据已加载,但滚动似乎不起作用。当我向下滚动gridview时,滚动条向上移动而不保留滚动位置。
以下是我的自定义 GridView 代码,
public class CustomAdapter extends BaseAdapter {
private Context context;
private List<PropertiesList> myList;
public CustomAdapter(List<PropertiesList> paramList, Context paramContext)
{
this.myList = paramList;
this.context = paramContext;
}
public int getCount()
{
return this.myList.size();
}
public Object getItem(int paramInt)
{
return Integer.valueOf(paramInt);
}
public long getItemId(int paramInt)
{
return paramInt;
}
public View getView(final int paramInt, View paramView, ViewGroup paramViewGroup)
{
View localView = View.inflate(this.context, R.layout.grid_content, null);
localView.setMinimumHeight((int)(0.3D * ((WindowManager)this.context.getSystemService("window")).getDefaultDisplay().getWidth()));
((TextView)localView.findViewById(R.prop_type)).setText(((PropertiesList)this.myList.get(paramInt)).PropertyAddress);
localView.findViewById(R.id.prop_type).setBackgroundResource(color.darker_gray);
((TextView)localView.findViewById(R.id.prop_price)).setText(((PropertiesList)this.myList.get(paramInt)).PropertyPrice);
localView.setId(paramInt);
((TextView)localView.findViewById(R.id.prop_type)).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(context, "PropertyID: "+myList.get(paramInt).PropertyID, Toast.LENGTH_SHORT).show();
}
});
return localView;
}
}
xml,
<GridView
android:id="@+id/camera_grid"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top|center"
android:columnWidth="110.0dip"
android:gravity="center"
android:horizontalSpacing="5.0dip"
android:numColumns="auto_fit"
android:orientation="vertical"
android:scrollingCache="false"
android:stretchMode="columnWidth"
android:verticalSpacing="5.0dip"
android:scrollbars="vertical" />
我的代码中有任何错误的实现吗?请帮我解决这个问题。
提前致谢!!
