Implémenter Searchview avec le tiroir de navigation et le fragment à l'intérieur

Question

Je veux implémenter SearchView sur la barre d'outils dans Navigation-Drawer et il y a Fragment Activity comme dans l'image. J'ai essayé SearchView sur Activity et j'ai réussi, mais quand je l'implémente à Fragment Activity, pourquoi son code ne peut pas fonctionner.

Ceci est mon Main Activity.java

public class MainActivity extends AppCompatActivity 
    implements NavigationView.OnNavigationItemSelectedListener { 

public static final String MAKAN = "makanan"; 
public static String WHERE = "makanan"; 
public static int WHERE2; 

String mQuery; 
ArrayList<Makanan> mlist = new ArrayList<>(); 
ArrayList<Makanan> mlistAll = new ArrayList<>(); 
public String mQuery2; 
boolean isFiltered; 
MakananAdapter mAdapter; 
ArrayList<Integer> mListMapFilter = new ArrayList<>(); 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
      this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); 
    drawer.setDrawerListener(toggle); 
    toggle.syncState(); 

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); 
    navigationView.setNavigationItemSelectedListener(this); 

    View header = ((NavigationView)findViewById(R.id.nav_view)).getHeaderView(0); 
    ImageButton ib = (ImageButton)header.findViewById(R.id.imageButton); 
    ib.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      Intent intent = new Intent(MainActivity.this, MapsActivity.class); 
      startActivity(intent); 
     } 
    }); 

setTitle("Beranda"); 
    Hal1 fragment = new Hal1(); 
    FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction(); 
    fragmentTransaction.replace(R.id.frame, fragment, "fragment1"); 
    //WHERE = "11"; 
    fragmentTransaction.commit(); 
} 

@Override 
public void onBackPressed() { 
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    if (drawer.isDrawerOpen(GravityCompat.START)) { 
     drawer.closeDrawer(GravityCompat.START); 
    } else { 
     super.onBackPressed(); 
    } 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // Handle action bar item clicks here. The action bar will 
    // automatically handle clicks on the Home/Up button, so long 
    // as you specify a parent activity in AndroidManifest.xml. 
    int id = item.getItemId(); 

    //noinspection SimplifiableIfStatement 
    if (id == R.id.action_settings) { 
     setTitle("About"); 
     Hal2 fragments = new Hal2(); 
     FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction(); 
     fragmentTransaction.replace(R.id.frame, fragments, "fragment1"); 
     fragmentTransaction.commit(); 
    } 

    return super.onOptionsItemSelected(item); 
} 

@SuppressWarnings("StatementWithEmptyBody") 
@Override 
public boolean onNavigationItemSelected(MenuItem item) { 
    // Handle navigation view item clicks here. 
    int id = item.getItemId(); 

    if (id == R.id.frag_all) { 
     setTitle("Rekomendasi"); 
     SecondFragment fragment = new SecondFragment(); 
     FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction(); 
     fragmentTransaction.replace(R.id.frame, fragment, "fragment1"); 
     WHERE = "11"; 
     fragmentTransaction.commit(); 
    } ... 

DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    drawer.closeDrawer(GravityCompat.START); 
    return true; 
}} 

Et Mon SecondFragment.java

public class SecondFragment extends Fragment implements MakananAdapter.IMakananAdapter, SearchView.OnQueryTextListener { 


public static final String MAKAN = "makanan"; 
    private AppCompatActivity compat; 
private RecyclerView recyclerView; 
private MakananAdapter adapter; 

public SecondFragment() {

//MakananAdapter mAdapter; 

String mQuery; 
ArrayList<Makanan> mlist = new ArrayList<>(); 
ArrayList<Makanan> mlistAll = new ArrayList<>(); 
boolean isFiltered; 

MakananAdapter mAdapter; 
ArrayList<Integer> mListMapFilter = new ArrayList<>(); 

private SearchView searchView = null; 
private SearchView.OnQueryTextListener queryTextListener; 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 

    View rootview = inflater.inflate(R.layout.activity_calling, container, false); 
    recyclerView = (RecyclerView) rootview.findViewById(R.id.recyclerView); 

    GridLayoutManager gridLayoutManager = new GridLayoutManager(getContext(), 2); 
    recyclerView .setHasFixedSize(true); 
    recyclerView .setItemAnimator(new DefaultItemAnimator()); 
    recyclerView .setLayoutManager(gridLayoutManager); 

    recyclerView.setLayoutManager(gridLayoutManager); 

    adapter = new MakananAdapter(mList); 
    recyclerView.setAdapter(adapter); 

    return rootview; 
} 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setHasOptionsMenu(true); 

    fillData1(); 

//if i use this call method, the function is work 
//[enter image description here][1]doFilter("roker"); 


} 


private void fillData1() { 
    Resources resources = getResources(); 
    String[] arJudul = resources.getStringArray(R.array.recommend); 
    String[] arDeskripsi = resources.getStringArray(R.array.recommend_desc); 
    String[] arHarga = resources.getStringArray(R.array.recommend_price); 
    String[] arDetail = resources.getStringArray(R.array.recommend_details); 
    String[] arLokasi = resources.getStringArray(R.array.recommend_locations); 
    String[] arLat = resources.getStringArray(R.array.recommend_lat); 
    String[] arLng = resources.getStringArray(R.array.recommend_longi); 
    TypedArray a = resources.obtainTypedArray(R.array.recommend_pict); 
    String[] arFoto = new String[a.length()]; 
    for (int i = 0; i < arFoto.length; i++) { 
     int id = a.getResourceId(i, 0); 

     arFoto[i] = ContentResolver.SCHEME_ANDROID_RESOURCE + "://" 
       + resources.getResourcePackageName(id) + '/' 
       + resources.getResourceTypeName(id) + '/' 
       + resources.getResourceEntryName(id) + '/'; 
    } 
    a.recycle(); 

    for (int i = 0; i < arJudul.length; i++) { 
     mList.add(new Makanan(arJudul[i], arDeskripsi[i], arFoto[i], arHarga[i], arDetail[i], arLokasi[i], arLat[i], arLng[i])); 
    } 

} 



@Override 
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { 
    inflater.inflate(R.menu.main, menu); 
    MenuItem searchItem = menu.findItem(R.id.action_search); 
    SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem); 
    searchView.setQueryHint("Cari"); 

    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() { 
     @Override 
     public boolean onQueryTextSubmit(String query) { 
      //Log.i("onQueryTextSubmit", query); 
      //mQuery = query.toLowerCase(); 
      //doFilter(mQuery); 
      return false; 
     } 

     @Override 
     public boolean onQueryTextChange(String newText) { 
      Log.i("onQueryTextChange", newText); 
      mQuery = newText.toLowerCase(); 
      doFilter(mQuery); 
      return true; 
     } 
    }); 
    return; 
} 

//My filter function goes here 
public boolean doFilter(String query) { 
    if (!isFiltered) { 
     mlistAll.clear(); 
     mlistAll.addAll(mList); 
     isFiltered = true; 
    } 

    mList.clear();

        makanan.deskripsi.toLowerCase().contains(query)) {

} 

@Override 
public boolean onQueryTextSubmit(String query) {

@Override 
public void doClick(int pos) { 
    Intent intent = new Intent(getContext(), DetailActivity.class); 
    intent.putExtra(MAKAN, mList.get(pos)); 
    startActivity(intent); 
}} 

Alors, ma question est de savoir comment exécuter la fonction doFilter avec requête en entrée utilisateur? Est-ce possible ? merci à l'avance

Answer 1

En supposant que vous avez ajouté searchable.xml dans res/xml/ répertoire du projet et dans votre AndroidManifest.xml, vous avez déclaré MainActivity comme searchable activité.

1. Ajouter menu.xml dans res/menu dossier contenant élément de menu qui utilise SearchView en utilisant app:actionViewClass="android.support.v7.widget.SearchView"

<item 
    android:id="@+id/action_search" 
    android:icon="@drawable/ic_action_search" 
    android:title="@string/search_hint" 
    app:showAsAction="collapseActionView|ifRoom" 
    app:actionViewClass="android.support.v7.widget.SearchView" /> 

2. Configuration SearchView et ajoutez à votre SearchView.setOnQueryTextListenerMainActivity.

3. Ony ajoute une fonction statique Filter dans votre classe Fragment. Par exemple:

public static void doFilter(String searchQuery) { 
     ........... 
     .................... 
    } 

Mettez à jour votre MainActivity comme ci-dessous:

public class MainActivity extends AppCompatActivity { 

    Context mContext; 

    // Default active navigation menu 
    int mActiveMenu; 

    // TAGS 
    public static final int MENU_FIRST = 0; 
    public static final int MENU_SECOND = 1; 

    // Action bar search widget 
    SearchView searchView; 
    String searchQuery = ""; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     mContext = this; 

     ................ 
     ........................... 

     // FirstFragment will show when app launch 
     mActiveMenu = MENU_FIRST; 
     displayViewWithFragment(mActiveMenu); 

     // NavigationView 
     mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() { 

      @Override 
      public boolean onNavigationItemSelected(MenuItem menuItem) { 

       //Check to see which item was being clicked and perform appropriate action 
       switch (menuItem.getItemId()) 
       { 
        case R.id.navigation_item_first: 
        { 
         // First 
         displayViewWithFragment(MENU_FIRST); 

         return true; 
        } 
        case R.id.navigation_item_second: 
        { 
         // Second 
         displayViewWithFragment(MENU_SECOND); 

         return true; 
        } 
        default: 
         return true; 
       } 
      } 
     }); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.main, menu); 

     // Getting search action from action bar and setting up search view 
     MenuItem searchItem = menu.findItem(R.id.action_search); 
     searchView = (SearchView)searchItem.getActionView(); 

     // Setup searchView 
     setupSearchView(searchItem); 

     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) 
    { 
     // Handle action bar actions click 
     switch (item.getItemId()) 
     { 
      case R.id.action_search: 
       return true; 

      default: 
       return super.onOptionsItemSelected(item); 
     } 
    } 

    // Search widget 
    private void setupSearchView(MenuItem searchItem) 
    { 
     SearchManager searchManager = (SearchManager) this.getSystemService(Context.SEARCH_SERVICE); 
     if (searchManager != null) 
     { 
      SearchableInfo info = searchManager.getSearchableInfo(getComponentName()); 
      searchView.setSearchableInfo(info); 
     } 

     searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() { 
      @Override 
      public boolean onQueryTextChange(String newText) 
      { 
       searchQuery = newText; 

       // Load search data on respective fragment 
       if(mActiveMenu == MENU_FIRST) // First 
       { 
        FirstFragment.doFilter(newText); 
       } 
       else if(mActiveMenu == MENU_SECOND) // Second 
       { 
        SecondFragment.doFilter(newText); 
       } 
       return true; 
      } 

      @Override 
      public boolean onQueryTextSubmit(String query) { 
       //searchView.clearFocus(); 
       return false; 
      } 
     }); 

     // Handling focus change of search view 
     searchView.setOnQueryTextFocusChangeListener(new OnFocusChangeListener() { 

      @Override 
      public void onFocusChange(View v, boolean hasFocus) { 

       // Focus changed after pressing back key or pressing done in keyboard 
       if (!hasFocus) { 
        searchQuery = ""; 
       } 
      } 
     }); 
    } 

    /** 
    * Displaying fragment view for selected nav drawer list item 
    * */ 
    private void displayViewWithFragment(final int position) { 

     // Active menu 
     mActiveMenu = position; 

     Fragment fragment = null; 
     switch (position) 
     { 
      case MENU_FIRST: 
      { 
       // First 
       fragment = new FirstFragment(); 
      } 
      break; 

      case MENU_SECOND: 
      { 
       // Second 
       fragment = new SecondFragment(); 
      } 
      break; 

      default: 
       break; 
     } 

     if (fragment != null) 
     { 
      mFragmentTransition = getSupportFragmentManager().beginTransaction(); 
      mFragmentTransition.replace(R.id.frame_container, fragment); 
      mFragmentTransition.commit(); 
     } 
    } 
} 

Ajouter la fonction filter-FirstFragment:

public static void doFilter(String searchQuery) 
{ 
    // Filter codes here 
    ................... 
    ............................. 

    // Update RecyclerView 
    adapter.notifyDataSetChanged(); 
} 

Espérons que cela aidera ~
