我想将资源文件夹（可绘制）的图像路径存储到 sqlite，然后检索它。我怎样才能做到这一点？
更新： 检索图像后，我在这里有一个按钮来重新排序/排序列表视图。这就是为什么我需要将图像路径存储到 sqlite。
这是我迄今为止尝试过的：
static final int[] imgs = {
R.drawable.dinaretreat, // 0
R.drawable.cobterrace, // 1
R.drawable.ventassostreet, // 2
R.drawable.summerhillblvddrouin, // 3
R.drawable.todmanstreetdrouin, // 4
R.drawable.aqueductroad, // 5
R.drawable.northroad, // 6
R.drawable.pottsroad, // 7
R.drawable.onemcclenaghanplace, // 8
R.drawable.twomcclenaghanplace, // 9
R.drawable.threemcclenaghanplace, // 10
R.drawable.fourmcclenaghanplace, // 11
R.drawable.fivemcclenaghanplace, // 12
R.drawable.sevenmcclenaghanplace, // 13
R.drawable.elevenplacemcclenaghanplace, // 14
R.drawable.twelvemcclenaghanplace, // 15
R.drawable.fivethreetwosummerhillblvddrouin, // 16
R.drawable.seventeenajaxstreetdrouin, // 17
R.drawable.onethirtythreemountainviewblvd, // 18
R.drawable.fivethreeonesummerhillblvddrouin // 19

在这里，我已经声明了这些可绘制对象。如何将它们的路径保存到 sqlite，然后将它们显示在我的自定义列表视图上？有任何想法吗？非常感谢您的帮助。谢谢。
