我正在尝试基于Stack Overflow的答案之一创建一个交互式infoWindow。
但是，我在代码中使用getMapAsync()时遇到了错误。尽管我尝试使用public class MainActivity extends AppCompatActivity {
private ViewGroup infoWindow;
private TextView infoTitle;
private TextView infoSnippet;
private Button infoButton1, infoButton2;
private OnInfoWindowElemTouchListener infoButtonListener;
static final LatLng latlng1 = new LatLng(28.5355, 77.3910);
static final LatLng latlng2 = new LatLng(28.6208768, 77.3726377);
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final SupportMapFragment mapFragment = (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map);
final MapWrapperLayout mapWrapperLayout = (MapWrapperLayout)findViewById(R.id.map_relative_layout);
final GoogleMap googleMap = mapFragment.getMap();
// MapWrapperLayout initialization
// 39 - default marker height
// 20 - offset between the default InfoWindow bottom edge and it's content bottom edge
mapWrapperLayout.init(googleMap, getPixelsFromDp(this, 39 + 20));
// We want to reuse the info window for all the markers,
// so let's create only one class member instance
this.infoWindow = (ViewGroup)getLayoutInflater().inflate(R.layout.custom_infowindow, null);
this.infoTitle = (TextView)infoWindow.findViewById(R.id.nameTxt);
this.infoSnippet = (TextView)infoWindow.findViewById(R.id.addressTxt);
this.infoButton1 = (Button)infoWindow.findViewById(R.id.btnOne);
this.infoButton2 = (Button)infoWindow.findViewById(R.id.btnTwo);
// Setting custom OnTouchListener which deals with the pressed state
// so it shows up
this.infoButtonListener = new OnInfoWindowElemTouchListener(infoButton1, getResources().getDrawable(R.drawable.btn_bg), getResources().getDrawable(R.drawable.btn_bg)){
@Override
protected void onClickConfirmed(View v, Marker marker) {
// Here we can perform some action triggered after clicking the button
Toast.makeText(MainActivity.this, "click on button 1", Toast.LENGTH_SHORT).show();
}
};
this.infoButton1.setOnTouchListener(infoButtonListener);
infoButtonListener = new OnInfoWindowElemTouchListener(infoButton2, getResources().getDrawable(R.drawable.btn_bg),getResources().getDrawable(R.drawable.btn_bg)){
@Override
protected void onClickConfirmed(View v, Marker marker) {
Toast.makeText(getApplicationContext(), "click on button 2", Toast.LENGTH_LONG).show();
}
};
infoButton2.setOnTouchListener(infoButtonListener);
/*infoWindow.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), "click on infowindow", Toast.LENGTH_LONG).show();
}
});*/
googleMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
@Override
public View getInfoWindow(Marker marker) {
return null;
}
@Override
public View getInfoContents(Marker marker) {
// Setting up the infoWindow with current's marker info
infoSnippet.setText(marker.getTitle());
infoTitle.setText(marker.getSnippet());
infoButtonListener.setMarker(marker);
// We must call this to set the current marker and infoWindow references
// to the MapWrapperLayout
mapWrapperLayout.setMarkerWithInfoWindow(marker, infoWindow);
return infoWindow;
}
});
// Let's add a couple of markers
googleMap.addMarker(new MarkerOptions()
.position(latlng1)
.title("Source")
.snippet("Comapny Name")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_GREEN)));
googleMap.addMarker(new MarkerOptions()
.position(latlng2)
.title("Destination")
.snippet("AmisunXXXXXX")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_ORANGE)));
//googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latlng, 15));
googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latlng1, 10));
}
public static int getPixelsFromDp(Context context, float dp) {
final float scale = context.getResources().getDisplayMetrics().density;
return (int)(dp * scale + 0.5f);
}
}
，但无法解决问题。请帮我。如果带有按钮的交互式信息窗口有新代码可用，请共享代码。
getMap()由于Google已删除了=IF(AND(B3<>0, B3<>A3), E3*D3*B3, E3*D3*A3)
，因此出现了错误，但是我不知道该方法的替代解决方案。
答案 0 :(得分：0)
更新
在您的主活动中定义private GoogleMap gMap并实现OnMapReadyCallback并实现onMapReady方法
在onMapReady中，您应该写此行
gMap = googleMap，然后您就可以在onMapReady
现在是时候在您的OnCreate方法中使用这些行了
SupportMapFragment supportMapFragment = (SupportMapFragment)
getSupportFragmentManager().findFragmentById(R.id.map);
supportMapFragment.getMapAsync(this);
它应该可以解决您的问题，希望对您有帮助
