有许多图像，绘制foder所以不是手动创建的所有图像资源ID的数组，我要动态绘制文件夹中得到阵列中的所有图像。 目前I M采用这种code：

there are many images in drawable foder so instead manually creating array of all image resource ids , i want to get all images dynamically of drawable folder in array. currently i m using this code:

for(int i=1;i<=9;i++)
    {
            int imageKey = getResources().getIdentifier("img"+i, "drawable", getPackageName());
            ImageView image = new ImageView(this);  
            image.setId(imgId);
            image.setImageResource(imageKey);    
            image.setScaleType(ImageView.ScaleType.FIT_XY);
            viewFlipper.addView(image, new LayoutParams(LayoutParams.FILL_PARENT,              LayoutParams.FILL_PARENT));
            imgId++;
        }

但在codeI需要手动编辑图像名称获取资源ID，但我想所有的图像与任何名称。

but in that code i need to manually edit the image name to get the resource id but i want to get all image with any name..

推荐答案

您可以使用反射来实现这一目标。

you can Use Reflection to achieve this.

导入字段类

进口java.lang.reflect.Field中;

，然后在code写这个

and then write this in your code

Field[] ID_Fields = R.drawable.class.getFields();
int[] resArray = new int[ID_Fields.length];
for(int i = 0; i < ID_Fields.length; i++) {
    try {
        resArray[i] = ID_Fields[i].getInt(null);
    } catch (IllegalArgumentException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

resArray [] 现在持有在应用程序中引用的所有可绘制。

resArray[] now holds references to all the drawables in your application.
