## Usage
### Layout for loadmore listview
``` xml
```
### Activity to LoadMoreListView
``` java
// set a listener to be invoked when the list reaches the end
((LoadMoreListView) getListView())
.setOnLoadMoreListener(new OnLoadMoreListener() {
public void onLoadMore() {
// Do the work to load more items at the end of list here
new LoadDataTask().execute();
}
});
private class LoadDataTask extends AsyncTask {
@Override
protected Void doInBackground(Void... params) {
if (isCancelled()) {
return null;
}
// Simulates a background task
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
}
for (int i = 0; i < mNames.length; i++)
mListItems.add(mNames[i]);
return null;
}
@Override
protected void onPostExecute(Void result) {
mListItems.add("Added after load more");
// We need notify the adapter that the data have been changed
((BaseAdapter) getListAdapter()).notifyDataSetChanged();
// Call onLoadMoreComplete when the LoadMore task, has finished
((LoadMoreListView) getListView()).onLoadMoreComplete();
super.onPostExecute(result);
}
@Override
protected void onCancelled() {
// Notify the loading more operation has finished
((LoadMoreListView) getListView()).onLoadMoreComplete();
}
}
```
### Layout for pullandload listview
``` xml
```
### Activity to PullAndLoadListView
Here we have to pass two listeners one to pull operation and the other to load operation
``` java
// Set a listener to be invoked when the list should be refreshed.
((PullAndLoadListView) getListView())
.setOnRefreshListener(new OnRefreshListener() {
public void onRefresh() {
// Do work to refresh the list here.
new PullToRefreshDataTask().execute();
}
});
// set a listener to be invoked when the list reaches the end
((PullAndLoadListView) getListView())
.setOnLoadMoreListener(new OnLoadMoreListener() {
public void onLoadMore() {
// Do the work to load more items at the end of list
// here
new LoadMoreDataTask().execute();
}
});
private class LoadMoreDataTask extends AsyncTask {
@Override
protected Void doInBackground(Void... params) {
if (isCancelled()) {
return null;
}
// Simulates a background task
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
}
for (int i = 0; i < mNames.length; i++)
mListItems.add(mNames[i]);
return null;
}
@Override
protected void onPostExecute(Void result) {
mListItems.add("Added after load more");
// We need notify the adapter that the data have been changed
((BaseAdapter) getListAdapter()).notifyDataSetChanged();
// Call onLoadMoreComplete when the LoadMore task, has finished
((PullAndLoadListView) getListView()).onLoadMoreComplete();
super.onPostExecute(result);
}
@Override
protected void onCancelled() {
// Notify the loading more operation has finished
((PullAndLoadListView) getListView()).onLoadMoreComplete();
}
}
private class PullToRefreshDataTask extends AsyncTask {
@Override
protected Void doInBackground(Void... params) {
if (isCancelled()) {
return null;
}
// Simulates a background task
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
}
for (int i = 0; i < mAnimals.length; i++)
mListItems.addFirst(mAnimals[i]);
return null;
}
@Override
protected void onPostExecute(Void result) {
mListItems.addFirst("Added after pull to refresh");
// We need notify the adapter that the data have been changed
((BaseAdapter) getListAdapter()).notifyDataSetChanged();
// Call onLoadMoreComplete when the LoadMore task, has finished
((PullAndLoadListView) getListView()).onRefreshComplete();
super.onPostExecute(result);
}
@Override
protected void onCancelled() {
// Notify the loading more operation has finished
((PullAndLoadListView) getListView()).onLoadMoreComplete();
}
}
