Googleマップapi v2でアラートダイアログを使用して住所を検索するにはどうすればよいですか？

Question

EditTextでAlertDialogを作成しました。ユーザーが「Buscar」（陽性のボタン）をクリックすると、に入力された住所にMarkerが表示されます。だから私はこのデータをに使うためにはEditTextのデータをMapFragmentに渡す必要があると思います。ここで

はAlertDialogと私のmainActivity.javaです：

package com.example.alex.testing_map; 

import android.content.DialogInterface; 
import android.content.Intent; 
import android.net.Uri; 
import android.os.Bundle; 
import android.support.design.widget.NavigationView; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentTransaction; 
import android.support.v4.view.GravityCompat; 
import android.support.v4.widget.DrawerLayout; 
import android.support.v7.app.ActionBarDrawerToggle; 
import android.support.v7.app.AlertDialog; 
import android.support.v7.app.AppCompatActivity; 
import android.support.v7.widget.Toolbar; 
import android.text.InputType; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.widget.EditText; 


public class MapsActivity extends AppCompatActivity 
    implements NavigationView.OnNavigationItemSelectedListener { 

private String location = ""; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_maps); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 

    DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 
    ActionBarDrawerToggle drawerToggle = new ActionBarDrawerToggle(
      this, drawerLayout, toolbar, R.string.openDrawer, R.string.closeDrawer); 

    drawerLayout.setDrawerListener(drawerToggle); 
    drawerToggle.syncState(); 

    Fragment fragment = new MapFragment(); 
    FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); 
    ft.add(R.id.frame_content, fragment); 
    ft.commit(); 

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

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

@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); 
    return true; 
} 


@Override 
public boolean onOptionsItemSelected(MenuItem item){ 

    switch (item.getItemId()){ 
     case R.id.add_item: 
      Intent intent = new Intent(this, AddMail.class); 
      this.startActivity(intent); 
      break; 
     case R.id.search: 
      AlertDialog.Builder builder = new AlertDialog.Builder(this); 
      builder.setTitle("Dirección"); 

      final EditText input = new EditText(this); 
      input.setInputType(InputType.TYPE_CLASS_TEXT); 
      builder.setView(input); 

      builder.setPositiveButton("Buscar", new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        location = input.getText().toString(); 

       } 
      }); 
      builder.setNegativeButton("Cancelar", new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        dialog.cancel(); 
       } 
      }); 

      builder.show(); 
      break; 
     default: 
      return super.onOptionsItemSelected(item); 
    } 

    return true; 

} 


@SuppressWarnings("StatementWithEmptyBody") 
@Override 
public boolean onNavigationItemSelected(MenuItem item) { 

    Fragment fragment = null; 

    switch (item.getItemId()){ 
     case R.id.mapa: 
      fragment = new MapFragment(); 
      FragmentTransaction ft1 = getSupportFragmentManager().beginTransaction(); 
      ft1.replace(R.id.frame_content, fragment); 
      ft1.commit(); 
      getSupportActionBar().setTitle(R.string.app_name); 
      break; 
     case R.id.help: 
      fragment = new Help(); 
      FragmentTransaction ft2 = getSupportFragmentManager().beginTransaction(); 
      ft2.replace(R.id.frame_content, fragment); 
      ft2.commit(); 
      getSupportActionBar().setTitle(item.getTitle()); 
      break; 
     case R.id.about: 
      fragment = new About(); 
      FragmentTransaction ft3 = getSupportFragmentManager().beginTransaction(); 
      ft3.replace(R.id.frame_content, fragment); 
      ft3.commit(); 
      getSupportActionBar().setTitle(item.getTitle()); 
      break; 
     case R.id.rate: 
      Intent face = new Intent(Intent.ACTION_VIEW); 
      face.setData(Uri.parse("fb://profile/" + "100000914715145")); 
      startActivity(face); 
      break; 
     default: 
      return true; 

    } 


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


} 

そして、私のMapFragment.java：

package com.example.alex.testing_map; 

import android.Manifest; 
import android.content.Context; 
import android.content.pm.PackageManager; 
import android.location.Criteria; 
import android.location.Location; 
import android.location.LocationManager; 
import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentManager; 
import android.support.v4.app.FragmentTransaction; 
import android.support.v4.content.ContextCompat; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 


import com.google.android.gms.maps.CameraUpdateFactory; 
import com.google.android.gms.maps.GoogleMap; 
import com.google.android.gms.maps.OnMapReadyCallback; 
import com.google.android.gms.maps.SupportMapFragment; 
import com.google.android.gms.maps.model.BitmapDescriptorFactory; 
import com.google.android.gms.maps.model.LatLng; 
import com.google.android.gms.maps.model.MarkerOptions; 



public class MapFragment extends Fragment implements OnMapReadyCallback { 


private GoogleMap mMap; 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup viewGroup, Bundle savedInstanceState) { 
    View view = inflater.inflate(R.layout.map_fragment, viewGroup, false); 
    FragmentManager manager = getFragmentManager(); 
    FragmentTransaction transaction = manager.beginTransaction(); 
    SupportMapFragment fragment = new SupportMapFragment(); 
    transaction.replace(R.id.mapView, fragment); 
    transaction.commit(); 

    fragment.getMapAsync(this); 
    return view; 
} 


@Override 
public void onMapReady(GoogleMap googleMap) { 
    mMap = googleMap; 
    if (ContextCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_FINE_LOCATION) 
      == PackageManager.PERMISSION_GRANTED) { 
     mMap.setMyLocationEnabled(true); 
    } else { 
     if (ContextCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_COARSE_LOCATION) 
       == PackageManager.PERMISSION_GRANTED) { 
      mMap.setMyLocationEnabled(true); 

     } else { 
     } 
    } 

    mMap.getUiSettings().setCompassEnabled(false); 
    mMap.getUiSettings().setIndoorLevelPickerEnabled(false); 
    mMap.getUiSettings().setMapToolbarEnabled(false); 
    mMap.getUiSettings().setRotateGesturesEnabled(false); 
    mMap.getUiSettings().setZoomControlsEnabled(false); 


    // Primer poso les coordenades i estableixo els punts (numerats amb lletres en castellà) 
    // i després afegeixo els marcadors, posant de localització 
    // el nom dels punts definits amb anterioritat 

    LocationManager locationManager = (LocationManager)getActivity().getSystemService(Context.LOCATION_SERVICE); 
    Criteria criteria = new Criteria(); 
    String provider = locationManager.getBestProvider(criteria, true); 
    Location location = locationManager.getLastKnownLocation(provider); 

    LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude()); 
    LatLng p1 = new LatLng(41.39355, 2.15473); 
    mMap.addMarker(new MarkerOptions().position(p1).icon(BitmapDescriptorFactory.fromResource(R.drawable.pointer_bici1))); 
    mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, 18)); 


} 

} 

Answer 1

私はあなたがやろうとしているのか理解として、あなたが表示されているAlertDialogがどこ検索ダイアログのようなものですあなたはアドレスクエリに入れて、Buscarボタンをクリックすると、seこれはGeocoderで使用されるMapFragmentになります。

単純に言えば、locationの値をEditTextからMapFragmentに渡すことだけです。コミュニティを中心に見て、そうのように、setArguments()を使用してHow to pass data from Activity to Fragmentにこの答えを見つけました：

Bundle bundle = new Bundle(); 
bundle.putString(key, value); // preferred key and the location string you want 
fragment.setArguments(bundle); 

そして、そのようFragmentでそれを受け取る：

@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
    Bundle savedInstanceState) { 
      String strtext=getArguments().getString("message"); // replace "message" with the key you used. 

    return inflater.inflate(R.layout.fragment, container, false); 
    } 

したい場合にも、リスナーを使用することができます。選択肢はあなたです。お役に立てれば。がんばろう。 :)
