Converting an ArrayAdapter to CursorAdapter for use in a SearchView
android, android-actionbar, android-cursoradapter, autocompletetextview, simplecursoradapter
Solution
That's strange `SearchView.setSuggestionsAdapter` accepts CursorAdapter only.
You could create MatrixCursor and fill it with data from String array. I hope you have small data collection.
Then pass the cursor to CursorAdapter.
String[] columnNames = {"_id","text"}
MatrixCursor cursor = new MatrixCursor(columnNames);
String[] array = getResources().getStringArray(R.array.allStrings); //if strings are in resources
String[] temp = new String[2];
int id = 0;
for(String item : array){
temp[0] = Integer.toString(id++);
temp[1] = item;
cursor.addRow(temp);
}
String[] from = {"text"};
int[] to = {R.id.name_entry};
busStopCursorAdapter = new SimpleCursorAdapter(context, R.layout.listentry, cursor, from, to);
Problem
How can I convert an `ArrayAdapter<String>` of static data into a `CursorAdapter` for using Suggestion Listener in `SearchView`? I have constructed the `ArrayAdapter<String>` from static data (`allString`) ``` ArrayAdapter<String> searchAdapter = new ArrayAdapter<String>(context, R.layout.listitem, allString); ``` and I use it for an `MultiAutoCompleteTextView` which works fine in devices with API level less than 11 ``` MultiAutoCompleteTextView findTextView.setAdapter(searchAdapter); ``` However my target API is level is 11 and for API>10 I use an `ActionBar` within which I would like to have a SearchView instead. Here's what I have tried: It does show the `ActionBar` with the embedded `SearchView` but does not give any suggestions as it would in the `MultiAutoCompleteTextView`. ``` @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); if (android.os.Build.VERSION.SDK_INT > 10){ inflater.inflate(R.menu.menu11, menu); searchView = (SearchView) menu.findItem(R.id.MENU_SEARCH).getActionView(); int[] to = {0}; CursorAdapter cursorAdapter = new SimpleCursorAdapter(context, R.layout.listitem, null, allBusStopString, to); searchView.setSuggestionsAdapter(cursorAdapter); searchView.setOnSuggestionListener(new OnSuggestionListener() { @Override public boolean onSuggestionClick(int position) { String selectedItem = (String)cursorAdapter.getItem(position); Log.v("search view", selectedItem); return false; } @Override public boolean onSuggestionSelect(int position) { return false; } }); }else{ inflater.inflate(R.menu.menu, menu); } return true; } ```
