SearchView in Toolbar hinzufügen

sia · 4. August 2017

Hallo zusammen,

ich würde gerne eine SearchView in Toolbar hinzufügen. Mein Problem ist, dass die SearchView nicht angezeigt wird.

Code

package com.example.de.sasitravel;


import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v4.view.MenuItemCompat;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.SearchView;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;


import java.util.ArrayList;
import java.util.Arrays;


public class SearchActivity extends AppCompatActivity {


    ArrayAdapter&lt;String&gt; adapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_search);
        ListView lv = (ListView) findViewById(R.id.lvAirports);
        ArrayList&lt;String&gt; arrayAirports = new ArrayList&lt;&gt;();
        arrayAirports.addAll(Arrays.asList(getResources().getStringArray(R.array.array_airports)));


        adapter = new ArrayAdapter&lt;String&gt;(SearchActivity.this, android.R.layout.simple_list_item_1 , arrayAirports);
        lv.setAdapter(adapter);
    }




    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.menu_search, menu);
        MenuItem searchItem = menu.findItem(R.id.menuSearch);
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);


        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener(){
            @Override
            public boolean onQueryTextSubmit(String query) {
                return false;
            }


            @Override
            public boolean onQueryTextChange(String newText) {
                adapter.getFilter().filter(newText);
                return false;
            }
        });




        return super.onCreateOptionsMenu(menu);
    }
}

Hallo
in der "activity_search.xml" bindest du eine ActionBar und eine ToolBar ein.

"android.support.design.widget.AppBarLayout..." ist die Actionbar die du nicht brauchst Ihr übergiebst du auch kein Menue.
Denn das Menue übergiebst du der TooBar "<android.support.v7.widget.Toolbar...."
Bei der Anzeige liegt die ActoinBar warscheinlich über der ToolBar.

Also lasse den Code für die AppBar mal weg.

XML

XML-Quellcode: activity_search.xml

Jetzt habe ich folgendes Probelm:
Ich habe eine String array in in dem Verzeichnis value/strings:

Code

&lt;resources&gt;
    &lt;string name="app_name"&gt;SaSiTravel&lt;/string&gt;


    &lt;string-array name="array_airports"&gt;
        &lt;item&gt;Germany Dusseldorf DUS&lt;/item&gt;
        &lt;item&gt;Germany Dusseldorf/Weeze NRN&lt;/item&gt;
        &lt;item&gt;Germany cologne/Bonn CGN&lt;/item&gt;
        &lt;item&gt;Germany Frankfurt International Airport FRN&lt;/item&gt;


    &lt;/string-array&gt;


&lt;/resources&gt;

Alles anzeigen

Momentan die Suche so funktioniert, dass nur wenn ich G oder g eingbene dann wird was angezeigt, ich möchte aber dass auch wenn ich zum Beispiel D eingebe, diese Items angezeigt werden.
<item>Germany Dusseldorf DUS</item>
<item>Germany Dusseldorf/Weeze NRN</item>Und dass man Mindestens 2 Buchstabe eingeben soll bevor ein Suchergebnis angezeigt wird.Wie kann ich meine Suchfunktion dafür erweitern??Danke
