ImageView.setImageResource(image[1]);
I hope I explained well...
我希望我解释得很好...

To do that, you don't want an array of Drawable's, just an array of resource identifiers, because 'setImageResource' takes those identifiers. How about this:
要做到这一点，您不需要 Drawable 数组，只需要资源标识符数组，因为 'setImageResource' 需要这些标识符。这个怎么样：
int[] myImageList = new int[]{R.drawable.thingOne, R.drawable.thingTwo};
// later...
myImageView.setImageResource(myImageList[i]);
Or for a resizable version:
或者对于可调整大小的版本：
ArrayList<Integer> myImageList = new ArrayList<>();
myImageList.add(R.drawable.thingOne);
// later...
myImageView.setImageResource(myImageList.get(i));

First of all you have to get all drawable IDs of your pictures with the following method:
首先，您必须使用以下方法获取图片的所有可绘制 ID：
int android.content.res.Resources.getIdentifier(String name, String defType, String defPackage)
For example, you could read all drawable IDs in a loop:
例如，您可以循环读取所有可绘制 ID：
int drawableId = resources.getIdentifier("picture01", "drawable", "pkg.of.your.java.files");
picture02...
picture03...
..and then save them into an Array of Bitmaps:
..然后将它们保存到位图数组中：
private Bitmap[] images;
images[i] = BitmapFactory.decodeResource(resources, drawableId);
Now you are able to use your images as array.
现在您可以将图像用作数组。

with respect of @Bevor, you can use getResources()method instead of android.content.res.Resourceslike this:
关于@Bevor，您可以使用getResources()方法而不是android.content.res.Resources这样：
ArrayList<Integer> imgArr = new ArrayList<Integer>();
for(int i=0;i<5;i++){
imgArr.add(getResources().getIdentifier("picture"+i, "drawable", "pkg.of.your.java.files"));
}
Usage:
用法：
imageView.setImageResource((int)imgArr.get(3));

String[] arrDrawerItems = getResources().getStringArray(R.array.arrDrawerItems); // Your string title array
// You use below array to create your custom model like
TypedArray arrDrawerIcons = getResources().obtainTypedArray(R.array.arrDrawerIcons);
for(int i = 0; i < arrDrawerItems.length; i++) {
drawerItemDataList.add(new DrawerItemModel(arrDrawerItems[i], arrDrawerIcons.getResourceId(i, -1), i == 0 ? true : false));
}
drawerItemAdapter = new DrawerItemAdapter(this, drawerItemDataList);
mDrawerList.setAdapter(drawerItemAdapter);
