Action bar with Search View. Reverse compatibility issues
- by suresh
I am building a sample app to demonstrate SearchView with filter and other Action Bar items.
I am able to successfully run this app on 4.2(Nexus 7). But it is not running on 2.3. I googled about the issue. Came to know that i should use SherLock Action bar. I just went to http://actionbarsherlock.com/download.html, downloaded the zip file and added the library as informed in the video: http://www.youtube.com/watch?v=4GJ6yY1lNNY&feature=player_embedde by WiseManDesigns. But still I am unable to figure out the issue.
Here is my code:
SearchViewActionBar.java
public class SearchViewActionBar extends Activity implements SearchView.OnQueryTextListener
{
private SearchView mSearchView;
private TextView mStatusView;
int mSortMode = -1;
private ListView mListView;
private ArrayAdapter<String> mAdapter;
protected CharSequence[] _options = { "Wild Life", "River", "Hill Station", "Temple", "Bird Sanctuary", "Hill", "Amusement Park"};
protected boolean[] _selections = new boolean[ _options.length ];
private final String[] mStrings = Cheeses.sCheeseStrings;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
setContentView(R.layout.activity_main);
// mStatusView = (TextView) findViewById(R.id.status_text);
// mSearchView = (SearchView) findViewById(R.id.search_view);
mListView = (ListView) findViewById(R.id.list_view);
mListView.setAdapter(mAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
mStrings));
mListView.setTextFilterEnabled(true);
//setupSearchView();
}
private void setupSearchView() {
mSearchView.setIconifiedByDefault(true);
mSearchView.setOnQueryTextListener(this);
mSearchView.setSubmitButtonEnabled(false);
//mSearchView.setQueryHint(getString(R.string.cheese_hunt_hint));
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.searchview_in_menu, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
mSearchView = (SearchView) searchItem.getActionView();
//setupSearchView(searchItem);
setupSearchView();
return true;
}
@Override
public boolean onPrepareOptionsMenu(Menu menu)
{
if (mSortMode != -1)
{
Drawable icon = menu.findItem(mSortMode).getIcon();
menu.findItem(R.id.action_sort).setIcon(icon);
}
return super.onPrepareOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
String c="Category";
String s=(String) item.getTitle();
if(s.equals(c))
{
System.out.println("same");
showDialog( 0 );
}
//System.out.println(s);
Toast.makeText(this, "Selected Item: " + item.getTitle(), Toast.LENGTH_SHORT).show();
return true;
}
protected Dialog onCreateDialog( int id )
{
return
new AlertDialog.Builder( this )
.setTitle( "Category" )
.setMultiChoiceItems( _options, _selections, new DialogSelectionClickHandler() )
.setPositiveButton( "SAVE", new DialogButtonClickHandler() )
.create();
}
public class DialogSelectionClickHandler implements DialogInterface.OnMultiChoiceClickListener
{
public void onClick( DialogInterface dialog, int clicked, boolean selected )
{
Log.i( "ME", _options[ clicked ] + " selected: " + selected );
}
}
public class DialogButtonClickHandler implements DialogInterface.OnClickListener
{
public void onClick( DialogInterface dialog, int clicked )
{
switch( clicked )
{
case DialogInterface.BUTTON_POSITIVE:
printSelectedPlanets();
break;
}
}
}
protected void printSelectedPlanets()
{
for( int i = 0; i < _options.length; i++ ){
Log.i( "ME", _options[ i ] + " selected: " + _selections[i] );
}
}
public void onSort(MenuItem item)
{
mSortMode = item.getItemId();
invalidateOptionsMenu();
}
public boolean onQueryTextChange(String newText) {
if (TextUtils.isEmpty(newText)) {
mListView.clearTextFilter();
} else {
mListView.setFilterText(newText.toString());
}
return true;
}
public boolean onQueryTextSubmit(String query)
{
mStatusView.setText("Query = " + query + " : submitted");
return false;
}
public boolean onClose()
{
mStatusView.setText("Closed!");
return false;
}
protected boolean isAlwaysExpanded()
{
return false;
}
}
