Question

我正在使用此代码创建文本位图，以便在Google地图中显示多边形的网格数。

我多次调用 txtToBitmap 方法，比如在谷歌地图中，项目中可能有350个网格，当我点击项目时，我调用此方法350次，点击项目后10次或更多次，堆空间增加，它让我误以下...我正在搜索这个6天，任何人都可以帮忙。

码

public void txtToBitmap(String text,double middlelatitude, double middlelongitude){
        //String text = GridsXY.get(forMarker-1);//"Hello world!";
        Bitmap b= Bitmap.createBitmap(60, 60, Bitmap.Config.ARGB_8888);
        Canvas c = new Canvas(b);
        c.drawBitmap(b, 0, 0, null);
        TextPaint textPaint = new TextPaint();
        textPaint.setAntiAlias(true);
        textPaint.setTextSize(16.0F);
        textPaint.setColor(Color.RED);
        StaticLayout sl= new StaticLayout(text, textPaint, b.getWidth()-8, Alignment.ALIGN_CENTER, 0.0f, 0.0f, false);
        c.translate(6, 40);
        sl.draw(c);
        GridMarker=mMap.addMarker(new MarkerOptions().position(new LatLng(middlelatitude, middlelongitude))
                .icon(BitmapDescriptorFactory.fromBitmap(b)));
        b.recycle();
        b=null;
}

logcat的

为什么用oom错误强制关闭，我看到堆空间不断增加

Answer 1

我无法解决这个问题，但尝试了解决方法。我创建了60 * 60缩小其质量的位图，并通过杀死应用程序在低内存（）上处理，它现在可以工作，但是等待更好的解决方法。

Android内存不足错误：位图超出了vm预算
