Question

got a few problem here and hoping that you could help me out.

Let me first clarify the situation:

I have a static array of Integer in which inside was a R.drawable.images. Codes are as follows

private   Integer[] imageIDs = {
            //R.drawable.medal_my_first_perxtamp,
            R.drawable.medal..._gray,
            R.drawable.medal_y...te_me_gray,
            R.drawable.medal_t...ring_gray,
            R.drawable.medal_gi...ray,
            R.drawable.medal_a..._gray,
            R.drawable.medal_se..gray,
            R.drawable.medal_p...._gray,
            R.drawable.medal_m..._gray,
            R.drawable.medal_lo.._gray,
            R.drawable.m..._gray,
            R.drawable.med..,
            R.drawable.med..on_gray
          };

Now what I am trying to do is change the value of imageIDs based on a condition so now ive added this code on getview

       sqlAdapter = new SQLiteAdapter(mContext);
        sqlAdapter.openToRead();
        List<Integer> imageIDList = Arrays.asList(imageIDs);
        String query2="Select achievementID  from achievementdata_tb where memberID = 101";
        Cursor cursor2 =sqlAdapter.read(query2);
        if (cursor2 != null && cursor2.moveToFirst()) {
            while(cursor2.moveToNext()){

                val =cursor2.getString(0);
                int val2 = Integer.parseInt(val);
                String returnDrawable = getDrawables(val);
                int intReturnDrawable = Integer.parseInt(returnDrawable);
                imageIDList.set(val2, intReturnDrawable);
            }
        }

Note that I am getting values from database(achievement_ID) and the values is (6,2,3)

So what I did is get the cursor’s item one by one and check it on a public void getDrawables consist of

        public String getDrawables(String str){
        if (str.equals("3")){
            str= "R.drawable.med...g";
        }
        else if (str.equals("2")){
            str= "R.drawable.med..._me";
        }
        else if (str.equals("6")){
            str= "R.drawable.me...._up";
        }
        return str; 
    }

See that I want to change the value of array imageIDs (which is a drawable) to another drawable image.

I dont have any error so I use debugger and found out that I am getting an error on this part int intReturnDrawable = Integer.parseInt(returnDrawable);

I am new to andriod but i know some basic functionalities..
Could you help me solve this out?

Answer 1

You can’t because, the return type of getDrawable() is String. And the String like "R.drawable.med...g" can’t parse to Integer.

So change the implementation of getDrawable() return proper int value ..

Instead do something like,

public int getDrawables(String str){
        int value = 0;
        if (str.equals("3")){
            value = R.drawable.med...g;
        }
        else if (str.equals("2")){
            value = R.drawable.med..._me;
        }
        else if (str.equals("6")){
           value = R.drawable.me...._up;
        }
        return value; 
    }
