Question

我在google map android中使用了5个标记，并且每5秒标记位置也会随着动画而变化。在这种情况下，我想根据缩放级别动态调整图标的大小。

Answer 1

只需尝试下面的代码片段，它就会被我使用。此方法将返回适合您的缩放级别，预期的高度和宽度的图像。

public T Do<T>(Func<X, T> something)
{
    try
    {
        var manager = CoreInfrastructure.GetManager(Prefix, Config.Param1, Config.Param2); //******
        if (manager != null) return something(manager);
        LoggingHandler.LogWarning(LogTitle, $"manager ({this}) is null.");
    }
    catch (MyException exp)
    {
        ExceptionHandler.HandleRecoverableException(exp, LogTitle,
            $"query on manager ({this}) failed.");
    }

    var msg = $"failed to query using manager ({this})!";
    LoggingHandler.LogCritical(LogTitle, msg);
    throw new MyException(msg);
}


public T Do<T>(Func<Y, T> something)
{
    try
    {
        var manager = CoreInfrastructure.GetManager(Prefix, Config.Param3); //******
        if (manager != null) return something(manager);
        LoggingHandler.LogWarning(LogTitle, $"manager ({this}) is null.");
    }
    catch (MyException exp)
    {
        ExceptionHandler.HandleRecoverableException(exp, LogTitle,
            $"query on manager ({this}) failed.");
    }

    var msg = $"failed to query using manager ({this})!";
    LoggingHandler.LogCritical(LogTitle, msg);
    throw new MyException(msg);
}

您可以通过创建具有自定义高度的位图来实现

Configuration.assertionMode = AssertionMode.SOFT;

然后将此位图添加到地图上。

int height = 100;// resize according to your zooming level
int width = 100;// resize according to your zooming level
BitmapDrawable bitmapdraw = (BitmapDrawable)getResources().getDrawable(R.mipmap.marker);
Bitmap b=bitmapdraw.getBitmap();
Bitmap finalMarker= Bitmap.createScaledBitmap(b, width, height, false);

希望这行得通！
