共享首选项ImageView

Question

我在Android工作室工作，我有这个应用程序，显示一个imageView，并有搜索栏，允许您编辑照片的RGB值，但当我从纵向旋转到横向（或反之亦然）时，imageView不会保存并返回原始imageView而不是我选择的那个。 Seekbars保留了他们的价值观。关于如何使用共享首选项来保存图像的任何想法？感谢

公共类MainActivity扩展了AppCompatActivity {

        //Colorize ImageView
        int newColor = barAlpha.getProgress() * 0x1000000
                + barR.getProgress() * 0x10000
                + barG.getProgress() * 0x100

        SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
        SharedPreferences.Editor editor = settings.edit();
        ColorValues = newColor;

        editor.putInt(COLOR_VALUES, ColorValues);
        // Commit the edits
        editor.commit();
    }

    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {}

    @Override

};



@Override
protected void onSaveInstanceState(Bundle icicle) {
    super.onSaveInstanceState(icicle);

    icicle.putInt(COLOR_VALUES, ColorValues);
}

如果我保存了颜色值（在没有此代码的情况下已经以某种方式保存），这就是它的样子。

if (savedInstanceState != null) {
        colorvalues = savedInstanceState.getInt("COLOR_VALUES");
        image = savedInstanceState.get??????????????????????

    }

图片不是Int，那么应该放在哪里？ 还得到像RBar = savedInstanceState.getInt这样的确切RGB值，因为Rbar是一个搜索栏而不是一个int ???
