从本地数据库获取数据,然后使用游标进行映射。自定义适配器显示类似于ListView的数据。当从数据库中添加/删除项目时,适配器应该刷新。下面尝试的解决方案在启动时崩溃了。有什么建议吗?
提前感谢, -D
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
ViewGroup p = parent;
if (v == null) {
LayoutInflater vi = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.items_row, p);
}
int size = mAdapter.getCount();
Log.d(TAG, "position " + position + " Size " + size);
if(size != 0){
if(position < size) return mAdapter.getView(position, v, p);
Log.d(TAG, "-position " + position + " Size " + size);
}
return null;
}
异常:
