Question

我有调整图像大小的方法，我想从数组中获取参数，但它一直显示错误说

incompatible types 
found int 
required android.graphics.drawable.Drawable

这是我的方法

public Drawable ResizeImage (int imgResize){
        Display imgPost = getWindowManager().getDefaultDisplay();
        double dvcWidth = imgPost.getWidth();

        BitmapDrawable imgBD = (BitmapDrawable)this.getResources().getDrawable(imgResize);
        double imgHeight = imgBD.getBitmap().getHeight();
        double imgWidth = imgBD.getBitmap().getWidth();

        double imgRatio = dvcWidth/imgWidth;
        int newImgHeight = (int) (imgHeight*imgRatio);

        Bitmap imgBmap = BitmapFactory.decodeResource(getResources(),imgResize);
        Drawable imgDrawable = new BitmapDrawable(this.getResources(),getResizedBitmap(imgBmap,newImgHeight,(int) dvcWidth));

        return imgDrawable;
    }

我的数组

int[] imgDvc= new int[]{
            ResizeImage(R.drawable.pc),
            R.drawable.ps4,
            R.drawable.xbone
}

我通过这里调用我的数组

List<HashMap<String,String>> aList = new ArrayList<HashMap<String,String>>();
         for(int i=0;i<10;i++){
        HashMap<String, String> hm = new HashMap<String,String>();
        hm.put("Dvc", Integer.toString(imgDvc[i]) );
        aList.add(hm);
    }
String[] game= {"Dvc"};

我用它来填写列表视图，谢谢你的答案。

如果您只想放置3张图片，只需使用3张图片视图，然后按比例调整尺寸
