Android: ViewHolder pattern and different types of rows?
ViewH开发者_JS百科older pattern improves ListView scrolling framerate, as seen in following example: https://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List14.html
Is it possible to keep this pattern while using different kind of Views for different rows?
In other words, is it possible to do something like:
public View getView(int position, View view, ViewGroup parent) {
// calculate viewID here
if (view == null || *view is not null but was created from different XML than viewID* ) {
view = mInflater.inflate(viewId, null);
Yes, though it is far better to override getViewTypeCount()
and getItemViewType()
in your Adapter. That will teach Android's object pool to only hand you a row of the proper type back in getView()
.
