SearchView can be added as actionView in menu using
app:useActionClass = "android.support.v7.widget.SearchView" .
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="rohksin.com.searchviewdemo.MainActivity">
<item
android:id="@+id/searchBar"
app:showAsAction="always"
app:actionViewClass="android.support.v7.widget.SearchView"
/>
</menu>
SearchView.OnQueryTextListener has two abstract methods. So your activity skeleton would now look like this after implementing SearchView text listener.
YourActivity extends AppCompatActivity implements SearchView.OnQueryTextListener{
public boolean onQueryTextSubmit(String query)
public boolean onQueryTextChange(String newText)
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
MenuItem searchItem = menu.findItem(R.id.searchBar);
SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setQueryHint("Search People");
searchView.setOnQueryTextListener(this);
searchView.setIconified(false);
return true;
}
This is how you can implement abstract methods of the listener.
@Override
public boolean onQueryTextSubmit(String query) {
// This method can be used when a query is submitted eg. creating search history using SQLite DB
Toast.makeText(this, "Query Inserted", Toast.LENGTH_SHORT).show();
return true;
}
@Override
public boolean onQueryTextChange(String newText) {
adapter.filter(newText);
return true;
}
You can come up with your own logic based on your requirement. Here is the sample code snippet to show the list of Name which contains the text typed in the SearchView.
public void filter(String queryText)
{
list.clear();
if(queryText.isEmpty())
{
list.addAll(copyList);
}
else
{
for(String name: copyList)
{
if(name.toLowerCase().contains(queryText.toLowerCase()))
{
list.add(name);
}
}
}
notifyDataSetChanged();
}
