梯度上姜饼 [英] gradient on Gingerbread

问题描述

更新结果
我有一个在Android 2.3梯度位图的一个问题。我读这大文章并德code。使用下一个选项我的位图：

Updated
I have a problem with gradient bitmaps on android 2.3. I read this great article and decode my bitmaps using next options:

BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
options.inDither = true;

而在Android 2.2一切都很好，但在Android甚至是解码后的2.3梯度文物依然存在。

And on android 2.2 everything is great, but on android 2.3 gradient artifacts remain even after that decoding.

我在2.3与我的位图运行从文章，应用程序和所有变种坏：16/32位，（不）抖动和RBG_565，ARGB_8888和ARGB_4444 - 梯度具有文物。我也试图脱code不带选项。一切正常。对不起，问题是在

I run application from article on 2.3 with my bitmaps and all variants are bad: 16/32 bit, (not) dither and RBG_565, ARGB_8888 and ARGB_4444 - gradient has artifacts. Also I tried to decode without options. Everything is ok. Sorry, problem was in

opts.inScaled=true;
opts.inDensity=100;
opts.inTargetDensity=800;

但是现在我需要做的是Android 2.3这个工作code和它仍然产生不好的梯度（在Android 2.2一切正常）：

But now I need to make working this code on android 2.3 and its still produce bad gradient (on android 2.2 everything is ok):

    ImageView imageView = (ImageView) tabView.findViewById(R.id.tabsImage);
    // decode bitmaps
    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inPreferredConfig = Bitmap.Config.ARGB_8888;
    options.inDither = true;
    Bitmap tabImageOn = BitmapFactory.decodeResource(mainActivity.getResources(), tabImageResourceOnId, options);
    Bitmap tabImageOff = BitmapFactory.decodeResource(mainActivity.getResources(), tabImageResourceOffId, options);
    // create new selector
    StateListDrawable tabImage = new StateListDrawable();
    tabImage.addState(new int[] { android.R.attr.state_selected }, new BitmapDrawable(mainActivity.getResources(), tabImageOn));
    tabImage.addState(new int[] {}, new BitmapDrawable(mainActivity.getResources(), tabImageOff));
    tabImage.setDither(true);
    // set selector to tab
    imageView.setImageDrawable(tabImage);

我试图设置窗口像素格式的onCreate /前/该方法接下来方式后：

I tried to set window pixel format in onCreate/before/after that method next way:

    WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
    lp.copyFrom(getWindow().getAttributes());
    lp.format = PixelFormat.RGBA_8888;
    getWindow().setAttributes(lp);

但什么也没有改变（这是姜饼，它使用32位窗口格式）。

But nothing has been changed (it's gingerbread, it's using 32 bit window format).

为什么如此行为出现，我怎么能解决我的问题？

Why do so behaviour appear and how can i solve my problem?

感谢。一天好！

推荐答案

与移动可绘制到华电国际文件夹解决。

solved with moving drawables to hdpi folder.
