创建位图时，宽度和高度必须大于0

我正在开发一个android应用程序。 Google地图和标记群集在我的应用程序中被强制执行。应用程序在4.4和棒棒糖设备上运行良好。我使用以下代码和recieving以下错误 java.lang.IllegalArgumentException异常创建自定义标记：宽度和高度必须> 0创建位图时，宽度和高度必须大于0

我使用此代码为创建自定义位图作为标记

private Bitmap getMarkerBitmapFromView(@DrawableRes int resId,String typeProfile) { 

    View customMarkerView = ((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.custom_marker_view, null); 
    RelativeLayout _markerType = (RelativeLayout) customMarkerView.findViewById(R.id.markertype); 
    ImageView markerImageView = (ImageView) customMarkerView.findViewById(R.id.image); 
    //ImageView markerStatus = (ImageView) customMarkerView.findViewById(R.id.onlieStatus); 

    if(typeProfile.equals("blue")) { 
     _markerType.setBackgroundResource(R.drawable.markr_general); 


    } else if(typeProfile.equals("green")){ 
     _markerType.setBackgroundResource(R.drawable.markr_interest); 


    } else if(typeProfile.equals("red")) { 
     _markerType.setBackgroundResource(R.drawable.markr_profession); 


    } 

    markerImageView.setImageResource(resId); 
    customMarkerView.measure(View.MeasureSpec.EXACTLY, View.MeasureSpec.EXACTLY); 
    customMarkerView.layout(0, 0, customMarkerView.getMeasuredWidth(), customMarkerView.getMeasuredHeight()); 
    customMarkerView.buildDrawingCache(); 
    Bitmap returnedBitmap = Bitmap.createBitmap(customMarkerView.getMeasuredWidth(), customMarkerView.getMeasuredHeight(), 
      Bitmap.Config.ARGB_8888); 
    Canvas canvas = new Canvas(returnedBitmap); 
    canvas.drawColor(Color.WHITE, PorterDuff.Mode.SRC_IN); 
    Drawable drawable = customMarkerView.getBackground(); 
    if (drawable != null) 
     drawable.draw(canvas); 
    customMarkerView.draw(canvas); 
    return returnedBitmap; 

}

这里是我的代码标记rendring类

private class PersonRenderer extends DefaultClusterRenderer<Person> { 
    private final IconGenerator mIconGenerator = new IconGenerator(getApplicationContext()); 
    private final IconGenerator mClusterIconGenerator = new IconGenerator(getApplicationContext()); 
    private final CircleImageView mImageView; 
    private final CircleImageView mClusterImageView; 
    private final int mDimension; 


    public PersonRenderer() { 
     super(getApplicationContext(), mMap, mClusterManager); 

     View multiProfile = getLayoutInflater().inflate(R.layout.custom_marker_view, null); 
     mClusterIconGenerator.setContentView(multiProfile); 
     mClusterImageView = (CircleImageView) multiProfile.findViewById(R.id.image); 

     mImageView = new CircleImageView(getApplicationContext()); 
     mDimension = (int) getResources().getDimension(R.dimen.custom_profile_image); 
     mImageView.setLayoutParams(new ViewGroup.LayoutParams(mDimension, mDimension)); 
     int padding = (int) getResources().getDimension(R.dimen.custom_profile_padding); 
     mImageView.setPadding(padding, padding, padding, padding); 
     mIconGenerator.setContentView(mImageView); 

    } 

    @Override 
    protected void onBeforeClusterItemRendered(Person item, MarkerOptions markerOptions) { 
     mImageView.setImageResource(item.profilePhoto); 


     markerOptions.icon(BitmapDescriptorFactory.fromBitmap(getMarkerBitmapFromView(item.profilePhoto,item.profileType))).title("asfas"); 
     //Bitmap icon = mIconGenerator.makeIcon(); 
     // markerOptions.icon(getMarkerBitmapFromView(item.profilePhoto)).title(item.name); 
    } 

    @Override 
    protected void onBeforeClusterRendered(Cluster<Person> cluster, MarkerOptions markerOptions) { 
     /* List<Drawable> profilePhotos = new ArrayList<Drawable>(Math.min(4, cluster.getSize())); 
     int width = mDimension; 
     int height = mDimension; 


     MultiDrawable multiDrawable = new MultiDrawable(profilePhotos); 
     multiDrawable.setBounds(0, 0, width, height); 

     mClusterImageView.setImageDrawable(multiDrawable); 
     Bitmap icon = mClusterIconGenerator.makeIcon(String.valueOf(cluster.getSize()));*/ 




     if(cluster.getSize() == 2) { 

      markerOptions.icon(BitmapDescriptorFactory.fromBitmap(getClusteredMarkerBitmapFromView(R.drawable.for_two,2,cluster))); 

     } else if(cluster.getSize() == 3) { 

      markerOptions.icon(BitmapDescriptorFactory.fromBitmap(getClusteredMarkerBitmapFromView(R.drawable.for_three,3,cluster))); 

     } else if(cluster.getSize() == 4) { 

      markerOptions.icon(BitmapDescriptorFactory.fromBitmap(getClusteredMarkerBitmapFromView(R.drawable.images_for,4,cluster))); 

     } else if(cluster.getSize() > 4) { 

      markerOptions.icon(BitmapDescriptorFactory.fromBitmap(getClusteredMarkerBitmapFromView(R.drawable.images_for,cluster.getSize(),cluster))); 

     } 


    } 

    @Override 
    protected boolean shouldRenderAsCluster(Cluster cluster) { 
     // Always render clusters. 
     return cluster.getSize() > 1; 
    } 
}

我认为如果你真的在控制台上打印宽度和高度的值，那么你会更好地理解你的程序是否真的能够获取一些实际值。当没有值尚未分配给它们时，您可能会调用宽度和高度。检查此[SO线程]（http://stackoverflow.com/questions/17605662/illegalargumentexception-width-and-height-must-be-0-while-loading-bitmap-from）以获取更多信息。 – noogui

谢谢，它有助于 –

这个问题解决了吗？ – noogui

我认为这将帮助，如果你实际打印在控制台上的宽度和高度的数值，以便竟被你d更好地理解你的程序是否真的能够获取一些实际值。当没有值尚未分配给它们时，您可能会调用宽度和高度。检查此SO线程以获取更多信息。
