Question

我们在谷歌地图中有一个我的位置图标，例如
我想用我想要的图标更改这个图标按钮有没有办法在谷歌地图中替换这个图标。我如何在 Android 中做到这一点。

由于问题不清楚，所以我添加了附加信息。在https://support.google.com/maps/answer/3093609?hl=en 中，您可以在 根据您的位置获取路线 部分中的第 2 点看到该图标已显示

修复您的位置->了解位置符号中的下面部分也解释了这些图标。

如您所见，它不是标记，而是我写的位置按钮所以我的问题是如何将该图标（位置按钮）更改为我想要的图标。

看到这个图标按钮也显示在谷歌地图图标图片中

Answer 1

是的，你可以，

我通过使用下面的代码将我的位置按钮重新定位到视图的右下角解决了我的地图片段中的这个问题，这是我的 MapsActivity.java :-

import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.RelativeLayout;

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.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;
    View mapView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.fragment_map);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapView = mapFragment.getView();
        mapFragment.getMapAsync(this);
            }

    /**
     * Manipulates the map once available.
     * This callback is triggered when the map is ready to be used.
     * This is where we can add markers or lines, add listeners or move the camera. In this case,
     * we just add a marker near Sydney, Australia.
     * If Google Play services is not installed on the device, the user will be prompted to install
     * it inside the SupportMapFragment. This method will only be triggered once the user has
     * installed Google Play services and returned to the app.
     */
    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;
        mMap.setMyLocationEnabled(true);

        // Add a marker in Sydney and move the camera
        LatLng sydney = new LatLng(-34, 151);
        mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));

        if (mapView != null &&
                mapView.findViewById(Integer.parseInt("1")) != null) {
            // Get the button view
            View locationButton = ((View) mapView.findViewById(Integer.parseInt("1")).getParent()).findViewById(Integer.parseInt("2"));
            // and next place it, on bottom right (as Google Maps app)
            RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams)
                    locationButton.getLayoutParams();
            // position on right bottom
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, 0);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
            layoutParams.setMargins(0, 0, 30, 30);
        }

    }
}

这是片段的布局：-

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.infogird.www.location_button_reposition.MapFragment">

    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:map="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />
</FrameLayout>

希望这能解决您的问题。谢谢。

我正在使用的东西

    ImageView btnMyLocation = (ImageView) ((View) mapFragment.getView().findViewById(Integer.parseInt("1")).getParent()).findViewById(Integer.parseInt("2"));
    btnMyLocation.setImageResource(R.drawable.ic_current_location);

    RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams)
            btnMyLocation.getLayoutParams();

    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE);
    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
    layoutParams.setMargins(0, 0, 30, 30);
    btnMyLocation.setLayoutParams(layoutParams);

希望对您有所帮助...

我知道这是一个迟到的回复，但这段代码对我有用..

     ImageView btnMyLocation = (ImageView) ((View) mapFragment.getView().findViewById(1).getParent()).findViewById(2);
        btnMyLocation.setImageResource(R.mipmap.ic_location_circle);

        RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams)
                btnMyLocation.getLayoutParams();
        // position on right bottom
        layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, 0);
        layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
        layoutParams.setMargins(0, 0, 30, 30);

编码愉快..！
