我正在为我的地图（Api v2）上的所有标记使用 InfoWindowAdapter。所有标记都清晰可见..
问题是我的自定义信息窗口的大小约为 500 像素 * 300 像素。当我触摸地图上的任何点时，它被设置为屏幕中心，因此信息窗口被从顶部裁剪。我的要求是根据信息窗口大小自动调整。
请看一下快照。

覆盖 的默认行为OnMarkerClickListener。
- 称呼
marker.showInfoWindow() - 计算应该在哪个屏幕上居中
Projection的位置，使用标记的位置和动画相机到该位置 - 返回
true
这个答案应该可以帮助您解决第二点：https ://stackoverflow.com/a/16764140/2183804

我有同样的问题，我尝试了以下完美的解决方案
mMap.setOnMarkerClickListener(new OnMarkerClickListener()
{
@Override
public boolean onMarkerClick(Marker marker)
{
int yMatrix = 200, xMatrix =40;
DisplayMetrics metrics1 = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics1);
switch(metrics1.densityDpi)
{
case DisplayMetrics.DENSITY_LOW:
yMatrix = 80;
xMatrix = 20;
break;
case DisplayMetrics.DENSITY_MEDIUM:
yMatrix = 100;
xMatrix = 25;
break;
case DisplayMetrics.DENSITY_HIGH:
yMatrix = 150;
xMatrix = 30;
break;
case DisplayMetrics.DENSITY_XHIGH:
yMatrix = 200;
xMatrix = 40;
break;
case DisplayMetrics.DENSITY_XXHIGH:
yMatrix = 200;
xMatrix = 50;
break;
}
Projection projection = mMap.getProjection();
LatLng latLng = marker.getPosition();
Point point = projection.toScreenLocation(latLng);
Point point2 = new Point(point.x+xMatrix,point.y-yMatrix);
LatLng point3 = projection.fromScreenLocation(point2);
CameraUpdate zoom1 = CameraUpdateFactory.newLatLng(point3);
mMap.animateCamera(zoom1);
marker.showInfoWindow();
return true;
}
});

检查下面的代码：我使用了简单的 alertDialog 你可以使用自定义或任何你想要的。
public class testclassmaps extends AbstractMapActivity {
private GoogleMap map;
private TextView text;
@Override
protected void onCreate(Bundle arg0) {
// TODO Auto-generated method stub
super.onCreate(arg0);
if (readyToGo()) {
setContentView(R.layout.showmaps);
text = (TextView) findViewById(R.id.editText1);
getSupportActionBar().setHomeButtonEnabled(true);
SupportMapFragment mapFrag = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
map = mapFrag.getMap();
// map.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
addMarker(map, 23.0333, 72.6167, "Ahmedabad", "");
addMarker(map, 22.3000, 73.1900, "Baroda", "");
map.setOnMapClickListener(new OnMapClickListener() {
@Override
public void onMapClick(LatLng point) {
// TODO Auto-generated method stub
map.addMarker(new MarkerOptions().position(point).title(
point.toString()));
Log.e("TAP MAP---->", "" + point);
text.setText("" + point);
}
});
}
map.setOnMarkerClickListener(new OnMarkerClickListener() {
@Override
public boolean onMarkerClick(Marker arg0) {
// TODO Auto-generated method stub
if (arg0.getTitle().equalsIgnoreCase("Ahmedabad")) {
new AlertDialog.Builder(testclassmaps.this)
.setTitle("Ahmedabad")
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
@Override
public void onClick(
DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
}
}).show();
}
if (arg0.getTitle().equalsIgnoreCase("Baroda")) {
new AlertDialog.Builder(testclassmaps.this)
.setTitle("Baroda")
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
@Override
public void onClick(
DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
}
}).show();
}
return false;
}
});
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
if (item.getItemId() == android.R.id.home) {
finish();
}
return super.onOptionsItemSelected(item);
}
private void addMarker(GoogleMap map, double lat, double lon,
String string, String string2) {
map.addMarker(new MarkerOptions().position(new LatLng(lat, lon))
.title(string).snippet(string2));
}
}
隐藏信息窗口使用marker.hideInfoWindow();内部标记单击
如果你不想使用 alertDialog 那么你可以使用自定义布局信息窗口如下方式：
map.setInfoWindowAdapter(new InfoWindowAdapter() {
@Override
public View getInfoWindow(Marker arg0) {
/*ContextThemeWrapper cw = new ContextThemeWrapper(
getApplicationContext(), R.style.Transparent);*/
// AlertDialog.Builder b = new AlertDialog.Builder(cw);
LayoutInflater inflater = (LayoutInflater) getApplicationContext()
.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater
.inflate(R.layout.custom_infowindow, null);
return layout;
}
@Override
public View getInfoContents(Marker arg0) {
return null;
}
});

我也遇到了同样的问题，经过很长时间我得到了有效的解决方案，可能它也适用于
公共布尔 onMarkerClick（标记标记）{
//Please use fix height popup
float container_height = getResources().getDimension(R.dimen.DIP_300);
Projection projection = mGoogleMap.getProjection();
Point markerScreenPosition = projection.toScreenLocation(marker.getPosition());
Point pointHalfScreenAbove = new Point(markerScreenPosition.x,(int) (markerScreenPosition.y - (container_height / 2)));
LatLng aboveMarkerLatLng = projection.fromScreenLocation(pointHalfScreenAbove);
marker.showInfoWindow();
CameraUpdate center = CameraUpdateFactory.newLatLng(aboveMarkerLatLng);
mGoogleMap.moveCamera(center);
mGoogleMap.animateCamera(center);
marker.showInfoWindow();
return true;
}
