android - 将可绘制对象放入 xml imageView 时不支持的图像类型

Question

当我通过代码在 imageview 中引用图像时:

<ImageView
   android:id="@+id/imageView2"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:src="@drawable/tequila" /> 

我在错误日志中收到以下错误:

javax.imageio.IIOException: Unsupported Image Type

    at android.view.LayoutInflater.inflate(LayoutInflater.java:372)

这是否正在发生？我无法在没有任何问题的情况下在我的电脑上打开图像，但 Eclipse 不喜欢，不采样我也不在图形布局中

谢谢。

也许您的 JPG 处于 CMYK 模式。尝试从代码设置 ImageView 的 src。

BitmapFactory.Options opts = new BitmapFactory.Options();
        opts.inPreferredConfig = Bitmap.Config.ARGB_8888;
        Bitmap bmp = BitmapFactory.decodeResource(getResources(), 
                                                          R.drawable.tequila, opts);
        ImageView view = (ImageView) findViewById(R.id.imageView2);
view.setImageBitmap(bmp);
