android使用片段和显示地图

Question

我有以下片段来显示谷歌地图中的位置。 1）好像我用

mwebView.loadUrl（ “https://www.google.com”）;

谷歌页面包含在我的片段中。注意汉堡包菜单

2）但如果我使用goole地图位置ex：

mwebView.loadUrl（ “https://www.google.com/maps/place/Pentecostals+of+Alexandria/@31.3069108,-92.4769955,17z/data=!4m5!3m4!1s0x0:0x2ced09e8ff5c3dbf!8m2!3d31.3069105!4d-92.4748012”）;

我的应用程序菜单（汉堡包丢失）谷歌地图汉堡包在那里，但我的应用程序菜单已经消失。

下面是代码：我想拥有应用程序汉堡包菜单，所以我可以回到菜单项.....帮助

public class find_us extends Fragment {

public find_us()
{
}

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

    commonfunc.myprint("#####_____find_us_onCreateView ");

    View rootView = inflater.inflate(life.poa.webcastman.poa1.R.layout.fragment_whats_hot, container, false);


    WebView mwebView = (WebView) rootView.findViewById(R.id.myWebView);
    WebSettings webSettings = mwebView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    //improve webView performance
    mwebView.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
    mwebView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
    mwebView.getSettings().setAppCacheEnabled(true);
    mwebView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
    webSettings.setDomStorageEnabled(true);
    webSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS);
    webSettings.setUseWideViewPort(true);
    webSettings.setSavePassword(true);
    webSettings.setSaveFormData(true);
    webSettings.setEnableSmoothTransition(true);

    mwebView.getSettings().setJavaScriptEnabled(true);

    //mwebView.loadUrl("https://www.google.com");
    mwebView.loadUrl("https://www.google.com/maps/place/Pentecostals+of+Alexandria/@31.3069108,-92.4769955,17z/data=!4m5!3m4!1s0x0:0x2ced09e8ff5c3dbf!8m2!3d31.3069105!4d-92.4748012");

    //force links open in webview only --- This was commented in archive ???
    //mwebView.setWebViewClient(new MyWebviewClient());
    commonfunc.myprint("webview0");
    return rootView;

嗯，对我来说，在网页浏览中使用谷歌地图不是最好的主意（除非是你的应用的要求）

如果您使用Google地图API，效果会更好。我要向您展示的代码是在片段中使用它。实际上我正在使用当前正在开发的应用程序中工作（并且工作正常：D）我希望，这对你来说很有帮助，如果出现问题，请告诉我

<强> fragment_map_layout.xml

'_'

现在位于 MapFragment

中

import re

df.toDF(*(re.sub(r'[\.\s]+', '_', c) for c in df.columns))

不要忘记在<fragment xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/map" android:name="com.google.android.gms.maps.SupportMapFragment" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_above="@+id/linearLayout" /> 应用

中设置public class MapFragment extends Fragment implements OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener { private GoogleMap mGoogleMap; private GoogleApiClient mGoogleApiClient; private static final int MY_LOCATION_PERMISSION = 100; @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_map, container, false); createGoogleClient(); return view; } @Override public void onStart() { super.onStart(); mGoogleApiClient.connect(); } @Override public void onStop() { super.onStop(); try { mGoogleApiClient.disconnect(); }catch (Exception e){ Log.wtf("onStop: ", "error " + e.getMessage() ); } } @Override public void onResume() { super.onResume(); setupUI(); } // remember since Android 6 we have to ask for permissions to the user: this is the callback @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { super.onRequestPermissionsResult(requestCode, permissions, grantResults); if (requestCode == MY_LOCATION_PERMISSION) if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){ // TODO: your code here } } // Here I setup the map and call getMapAsync(); method private void setupUI(){ SupportMapFragment mapFragment = (SupportMapFragment) this.getChildFragmentManager() .findFragmentById(R.id.map); mapFragment.getMapAsync(this); } // here I init the GoogleApiClient that help me to get the current location and set the callback private void createGoogleClient(){ if (mGoogleApiClient == null){ mGoogleApiClient = new GoogleApiClient.Builder(getActivity()) .addConnectionCallbacks(this) .addOnConnectionFailedListener(this) .addApi(LocationServices.API) .build(); mGoogleApiClient.connect(); } } // this method is used to ask for permissions in run time, the validations here is only to know the current device Android version if is > Android 6 ask for permissions @TargetApi(Build.VERSION_CODES.M) private boolean findLocation() { if ((Build.VERSION.SDK_INT < Build.VERSION_CODES.M) || getActivity().checkSelfPermission(ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) { mGoogleMap.setMyLocationEnabled(true); mGoogleMap.clear(); Location location = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient); setCurrentLocation(location); } else if (shouldShowRequestPermissionRationale(ACCESS_FINE_LOCATION)) { Toast.makeText(getActivity(), "message for the user", Toast.LENGTH_LONG).show(); } else { requestPermissions(new String[]{ACCESS_FINE_LOCATION}, MY_LOCATION_PERMISSION); } return false; } // set the current location in the google map private void setCurrentLocation(Location location) { if (location != null) { LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude()); CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(latLng, 17); mGoogleMap.animateCamera(cameraUpdate); }else mGoogleApiClient.reconnect(); } private boolean isGpsEnabled() { LocationManager lm = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);; boolean isEnabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER); if (!isEnabled) { android.app.AlertDialog.Builder dialog = new android.app.AlertDialog.Builder(getActivity()) .setMessage("Please, turn up your GPS") .setPositiveButton("Open settings", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface paramDialogInterface, int paramInt) { Intent myIntent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); startActivity(myIntent); } }) .setNegativeButton("Cancelar", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface paramDialogInterface, int paramInt) { //finish(); Toast.makeText(getActivity().getApplicationContext(), "Es necesario que habilites tu GPS", Toast.LENGTH_SHORT).show(); } }); dialog.show(); } return isEnabled; } @Override public void onMapReady(GoogleMap googleMap) { mGoogleMap = googleMap; mGoogleMap.moveCamera(CameraUpdateFactory.newLatLng(new LatLng(19.42499, -99.18644))); } @Override public void onConnected(@Nullable Bundle bundle) { if (isGpsEnabled()) findLocation(); } @Override public void onConnectionSuspended(int i) { // TODO: your code here } @Override public void onConnectionFailed(@NonNull ConnectionResult connectionResult) { // TODO: your code here } }
