将xml布局转为Bitmap

1.需求

将包含图片(Imageview),文字(TextView)等xml控件转化成Bitmap.

2.实现示例

代码

view.clearFocus();
        view.setPressed(false);
        boolean willNotCache = view.willNotCacheDrawing();
        view.setWillNotCacheDrawing(false);
        int color = view.getDrawingCacheBackgroundColor();
        view.setDrawingCacheBackgroundColor(0);
        if (color != 0) {
            view.destroyDrawingCache();
        }
        view.buildDrawingCache();
        Bitmap cacheBitmap = view.getDrawingCache();
        if (cacheBitmap == null) {
            return null;
        }
        Bitmap bitmap = Bitmap.createBitmap(cacheBitmap);
        view.destroyDrawingCache();
        view.setWillNotCacheDrawing(willNotCache);
        view.setDrawingCacheBackgroundColor(color);
        return bitmap;
复制代码

效果

以上代码便可实现将布局转为Bitmap对象!
