[android] How to convert int to Integer

private static HashMap<Integer, Bitmap> mBitmapCache;         
mBitmapCache.put(R.drawable.bg1,object);                       

R.drawable.bg1 is an int ... but i want to convert into Integer because Hashmap takes an Integer... and when draw the multiple objects in seconds , it creates a Integer Object runtime which affects the performence of the code...

As mentioned, one way is to use

new Integer(my_int_value)

But you should not call the constructor for wrapper classes directly

So, modify the code accordingly:

mBitmapCache.put(Integer.valueOf(R.drawable.bg1),object);

i it integer, int to Integer

Integer intObj = new Integer(i);

add to collection

list.add(String.valueOf(intObj));

I had a similar problem . For this you can use a Hashmap which takes "string" and "object" as shown in code below:

/** stores the image database icons */
public static int[] imageIconDatabase = { R.drawable.ball,
        R.drawable.catmouse, R.drawable.cube, R.drawable.fresh,
        R.drawable.guitar, R.drawable.orange, R.drawable.teapot,
        R.drawable.india, R.drawable.thailand, R.drawable.netherlands,
        R.drawable.srilanka, R.drawable.pakistan,

};
private void initializeImageList() {
    // TODO Auto-generated method stub
    for (int i = 0; i < imageIconDatabase.length; i++) {
        map = new HashMap<String, Object>();

        map.put("Name", imageNameDatabase[i]);
        map.put("Icon", imageIconDatabase[i]);
    }

}

int iInt = 10;
Integer iInteger = new Integer(iInt);
