我有一个应用程序，使用android-maps-utils和glide用于标记图标。
我收到了Firebase崩溃报告，但在源代码中无法跟踪gms.maps.model.Marker.setIcon是私有的，所以我需要一些帮助解决这个问题。
以下问题分为：
- 用户正在做什么
- Firebase崩溃报告了什么信息给我
- 一些项目配置
- 我尝试了/发现了什么来理解/修复它
用户正在做什么
他正在地图上缩放（使用com.google.android.gms.maps.SupportMapFragment的Fragment）

以及：
一些项目配置
- 我正在使用自定义渲染器（
SucursalRender extends DefaultClusterRenderer<Sucursal>） - 我正在使用 Glide 下载标记图标，就像我之前说的那样：
Glide.with(context).load(id).fitCenter().placeholder(R.drawable.ic_no_image).into(simpleTarget);
simpleTarget 是我处理 Glide 下载/缓存的图像的地方。 我将所有与 simpleTarget 相关的代码都发布了，因为崩溃是从那里开始的：
private class CustomSimpleTarget extends SimpleTarget<GlideDrawable> {
Sucursal sucursal;
Marker markerToChange = null;
@Override
public void onResourceReady(GlideDrawable resource, GlideAnimation<? super GlideDrawable> glideAnimation) {
mImageView.setImageDrawable(resource);
//currentSelectedItem is the current element selected in the map (Sucursal type)
//mIconGenerator is a: CustomIconGenerator extends IconGenerator
if (currentSelectedItem != null && sucursal.idalmacen.contentEquals(currentSelectedItem.idalmacen))
mIconGenerator.customIconBackground.useSelectionColor(true, ContextCompat.getColor(mContext, R.color.colorAccent));
else
mIconGenerator.customIconBackground.useSelectionColor(false, 0);
Bitmap icon = mIconGenerator.makeIcon();
if (markerToChange == null) {
for (Marker marker : mClusterManager.getMarkerCollection().getMarkers()) {
if (marker.getPosition().equals(sucursal.getPosition())) {
markerToChange = marker;
}
}
}
// if found - change icon
if (markerToChange != null) {
//GlideShortcutDrawable is a WeakReference<>(drawable)
sucursal.setGlideShortCutDrawable(resource);
markerToChange.setIcon(BitmapDescriptorFactory.fromBitmap(icon));
}
}
}
markerToChange.setIcon(BitmapDescriptorFactory.fromBitmap(icon));。我尝试在4个真实设备上重现错误，但没有成功。我在网上搜索了关于gms.maps.model.Marker.setIcon或com.google.maps.api.android.lib6的类似错误或代码。我试图理解Android Studio中给出的Marker.setIcon的混淆代码。我猜可以将代码包装在try-catch块中，以避免应用程序因崩溃而关闭，但这只是权宜之计。更新： DefaultClusterRenderer的代码。public class SucursalRender extends DefaultClusterRenderer<Sucursal> {
/**

*/
private final CustomIconGenerator mIconGenerator;

mClusterIconGenerator = new IconGenerator(mContext.getApplicationContext());
int padding = (int) mContext.getResources().getDimension(R.dimen.custom_profile_padding);
int dimension = (int) mContext.getResources().getDimension(R.dimen.custom_profile_image);
//R.layout.map_cluster_layout is a simple XML with the visual elements to use in markers and cluster
View view = ((AppCompatActivity)mContext).getLayoutInflater().inflate(R.layout.map_cluster_layout, null);
mClusterIconGenerator.setContentView(view);

mClusterImageView.setPadding(padding, padding, padding, padding);
mImageView = new ImageView(mContext.getApplicationContext());
mImageView.setLayoutParams(new ViewGroup.LayoutParams(dimension, dimension));
mImageView.setPadding(padding, padding, padding, padding);
mIconGenerator.setContentView(mImageView);
CustomIconBackground customIconBackground = new CustomIconBackground(false);
mIconGenerator.setBackground(customIconBackground);
mIconGenerator.customIconBackground = customIconBackground;
mClusterIconGenerator.setBackground(new CustomIconBackground(true));

@Override

ImageLoaderManager 只是 Glide 的一个门面。
public static void setImageFromId(SimpleTarget<GlideDrawable> simpleTarget, String id, Context context) {
if (context instanceof AppCompatActivity) {
AppCompatActivity activity = (AppCompatActivity)context;
if (activity.isDestroyed())
return;
}
Glide.with(context)
.load(id)
.fitCenter()
.placeholder(R.drawable.ic_no_image)
.into(simpleTarget);
}
CustomSimpleTarget是一个异步进程（当Glide正在下载图像时）。当图像被下载时，您不知道标记的状态，并且您可以传递到构造函数中的标记仍然可能在内存中但未显示在地图中（因为正在与地图中的新标记同步处理，请查看android-maps-utils中缩放时标记如何更新，您就会理解我在说什么）。 - MiguelHincapieCif (markerToChange == null)将有助于解决这个问题（好的，我要试一下）。 你是指更改整个“渲染”，是吗：SucursalRender？ 我是根据 google-maps-utils 的演示和一些很好的投票答案与片段来做的。像我之前说的，如果你有更好的方法，我会很乐意使用它；）。我可以在很多关于它的问题（google-maps-utils 和异步下载内容）中引用它，以帮助人们使用它。 - MiguelHincapieCClusterRenderer角色是根据地图状态（例如缩放级别）不断渲染标记（对于单个项目/聚类）。onBeforeRender回调与RecyclerView.Adapter.bindHolder.bindViewHolder()类似。请查看DefaultClusterRenderer.RenderTask代码 - 当动画时它不断删除标记并添加新标记。您的代码与CustomMarkerClusteringDemoActivity中的代码的区别在于，那里的setIcon操作是同步的，而您的则是异步的。您应该在模型中异步加载，在渲染时进行同步。 - Yoni Gross
