问题描述

我有一个ImageView的是32×32。它是一种基本的精灵。但是，当我去高档的形象，它模糊是这样的：

I have an ImageView that is 32x32. Its a sprite basically. But when I go to upscale the image, it blurs like this:

但我想它在这样的应用程序扩展：

But I want it to scale up in the application like this:

这是code我都试过了，但它不工作。我想被上的ImageView把最终的图像。

This is the code I have tried, but it doesn't work. I want the final image to be put on an ImageView.

@Override
        public View getView(int i, View view, ViewGroup viewGroup)
        {
            View v = view;
            ImageView picture;
            TextView name;

            if(v == null)
            {
               v = inflater.inflate(R.layout.gridview_item, viewGroup, false);
               v.setTag(R.id.picture, v.findViewById(R.id.picture));
               v.setTag(R.id.text, v.findViewById(R.id.text));
            }

            picture = (ImageView)v.getTag(R.id.picture);
            name = (TextView)v.getTag(R.id.text);

            Item item = (Item)getItem(i);
            Options options = new BitmapFactory.Options();
            options.inDither = false; //I THOUGHT THAT TURNING THIS TO FALSE WOULD MAKE IT NOT BLUR, BUT IT STILL BLURRED
            options.inScaled = false;
            Bitmap source = BitmapFactory.decodeResource(getResources(), item.drawableId, options); //THIS IS THE BITMAP. THE RESOURCE IS THE ID OF THE DRAWABLE WHICH IS IN AN ARRAY IN ANOTHER PLACE IN THIS FILE
            picture.setImageBitmap(source); //THIS SETS THE IMAGEVIEW AS THE BITMAP DEFINED ABOVE
            name.setText(item.name);

            return v;
        }

        private class Item
        {
            final String name;
            final int drawableId;

            Item(String name, int drawableId)
            {
                this.name = name;
                this.drawableId = drawableId;
            }
        }
    }

推荐答案

使用<一个href=\"http://developer.android.com/reference/android/graphics/Bitmap.html#createScaledBitmap%28android.graphics.Bitmap,%20int,%20int,%20boolean%29\"相对=nofollow> 位图＃createScaledBitmap（位图SRC，诠释dstWidth，诠释dstHeight，布尔型过滤器） 。其中一个参数是过滤一个布尔值：请确保您设置为false

Use Bitmap#createScaledBitmap(Bitmap src, int dstWidth, int dstHeight, boolean filter). One of the parameters is a boolean for filtering: make sure you set that to false.
