Android 在mapreday信息窗口
构建基于位置的应用程序 单击标记时,我会将标记添加到“地图和信息”窗口 代码:Android 在mapreday信息窗口,android,google-maps,Android,Google Maps,构建基于位置的应用程序 单击标记时,我会将标记添加到“地图和信息”窗口 代码: public void onMapReady(GoogleMap googleMap) { mMap = googleMap; UiSettings uiSettings = mMap.getUiSettings(); uiSettings.setMyLocationButtonEnabled(false); uiSettings.setMapToolbarEnabled(false)
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
UiSettings uiSettings = mMap.getUiSettings();
uiSettings.setMyLocationButtonEnabled(false);
uiSettings.setMapToolbarEnabled(false);
mMapCoastLocationService.init(mMap);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
mMap.setMyLocationEnabled(true);
// set the markers - new
mMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
@Override
public View getInfoWindow(Marker marker) {
return null;
}
@Override
public View getInfoContents(Marker marker) {
View view = LayoutInflater.from(context).inflate(R.layout.map_marker_info_contents, null, false);
//ImageView icon = (ImageView) view.findViewById(R.id.marker_info_window_icon);
//icon.setImageResource(R.drawable.info);
TextView title = (TextView) view.findViewById(R.id.marker_info_window_title);
title.setText(marker.getTitle());
return view;
}
});
mMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {
@Override
public void onInfoWindowClick(Marker marker) {
Integer coastId = mMapCoastLocationService.getCoastIdByMarker(marker);
startCoastDetailsActivity(coastId);
}
});
mFocusMyLocationButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
focusMyLocation();
}
});
}
用于标记的xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="horizontal">
<ImageView
android:id="@+id/marker_info_window_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:contentDescription="info image"
android:src="@drawable/info" />
<TextView
android:id="@+id/marker_info_window_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"`enter code here`
android:layout_marginLeft="@dimen/marker_text_margin"
android:layout_marginStart="@dimen/marker_text_margin"
android:text="example"
android:textColor="#000"/>
</LinearLayout>
问题是,当我第一次运行应用程序时,当我单击一个标记时,我只得到文本,而不是图标,而且单击不起作用
第二次一切都很好
有什么帮助吗?这是因为谷歌地图信息窗口在显示信息窗口之前(单击时)会将其渲染为位图 这意味着,如果您有来自web的图像源或大型本地资源要加载到InfoWindow内部的ImageView中,则在InfoWindow渲染完成之前可能无法完成 第二次加载图像时,信息窗口已呈现,因此它将显示 解决方案(使用Glide如下所示):
