Android: clear the listview data on button click
Question
In my app I have a listview where it is loading data based on the search keyword, now I want to clear the loaded data on button click.
@Override
protected void onPreExecute() {
SearchUtils searchUtils = null;
List<Place> searchResult = null;
String searchType = null;
Log.d(TAG, "onPreExecute start=");
// show your dialog
super.onPreExecute();
Log.d(TAG, "LoadMenuSearch isOldDataToLoad : " + isOldDataToLoad);
if(!this.isOldDataToLoad){
this.dialog.setCanceledOnTouchOutside(false);
this.dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
this.dialog.setOnCancelListener(new OnCancelListener() {
@Override
public void onCancel(DialogInterface arg0) {
}
});
Button morerecords = (Button) activity.findViewById(R.id.morerecords);
morerecords.setVisibility(View.GONE);
morerecords.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Log.d(TAG, "Do Nothing........................");
}
});
//morerecords.setVisibility(View.VISIBLE);
final Button closesearch = (Button) activity.findViewById(R.id.closesearch);
closesearch.setVisibility(View.VISIBLE);
closesearch.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
ListView menuSearchListView = (ListView) activity
.findViewById(R.id.menusearchlist);
searchAdapter.clear();
searchAdapter.notifyDataSetChanged();
closesearch.setVisibility(View.GONE);
}
});
Here in the preexecute I have a button, now when I click the button loaded data should be clear and the listview should get refreshed.

Try like this way
list.clear();
adpater.notifyDataSetChanged();
/// remove item from list.
adapter.clear();
adpater.notifyDataSetChanged();
Not all Adapters have a clear() method. ArrayAdapter does, but ListAdapter or SimpleAdapter doesn't

Just notify the listview after clearing the data of adapter i guess searchAdapter is your adapter . SearchAdapter is a custom adapter where you need to clear data based on type of adapter then call notifyDataSetChanged.

This is the code for clearing listview data on button click
Button yourbutton; // init it
yourButon.setOnClickListener(new OnClickListener(){
yourList.clear(); // this list which you hava passed in Adapter for your listview
yourAdapter.notifyDataSetChanged(); // notify to listview for refresh
});
