  • 0

I’ve created a list of recipes using Listview/customcursoradapter. A custom layout includes a photo for the recipe , Now I’ve some problems with the performance of viewing and scrolling the ListView although it has only 10 records (Target is 150). Sometimes I get this error java.lang.OutOfMemoryError: bitmap size exceeds VM budget, I’ve tried to implement the AsyncTask but I failed to do it. Is there any way I can overcome this problem?

Your help is highly appreciated !!

Here is my getView method

public View getView(int position, View convertView, ViewGroup parent) {
    View row = super.getView(position, convertView, parent);
    Cursor cursbbn  = getCursor();
    if (row == null)
    {
        LayoutInflater inflater = (LayoutInflater) localContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        row = inflater.inflate(R.layout.listtype, null);
    }

    String Title = cursbbn.getString(2);
    String SandID=cursbbn.getString(1);
    String Readyin = cursbbn.getString(4);
    String Faovoites=cursbbn.getString(8);

    TextView titler=(TextView)row.findViewById(R.id.listmaintitle);
    TextView readyinr=(TextView)row.findViewById(R.id.listreadyin);

    int colorPos = position % colors.length;
    row.setBackgroundColor(colors[colorPos]);

    titler.setText(Title);
    readyinr.setText(Readyin);

    ImageView picture = (ImageView) row.findViewById(R.id.imageView1);

    Bitmap bitImg1 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0001);
    Bitmap bitImg2 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0002);
    Bitmap bitImg3 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0003);
    Bitmap bitImg4 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0004);
    Bitmap bitImg5 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0005);
    Bitmap bitImg6 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0006);
    Bitmap bitImg7 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0007);
    Bitmap bitImg8 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0008);
    Bitmap bitImg9 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0009);
    Bitmap bitImg10 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0010);

    if(SandID.contentEquals("0001"))
        picture.setImageBitmap(getRoundedCornerImage(bitImg1));

    if(SandID.contentEquals("0002"))
        picture.setImageBitmap(getRoundedCornerImage(bitImg2));

    if(SandID.contentEquals("0003"))
        picture.setImageBitmap(getRoundedCornerImage(bitImg3));

    if(SandID.contentEquals("0004"))
        picture.setImageBitmap(getRoundedCornerImage(bitImg4));

    if(SandID.contentEquals("0005"))
        picture.setImageBitmap(getRoundedCornerImage(bitImg5));

    if(SandID.contentEquals("0006"))
        picture.setImageBitmap(getRoundedCornerImage(bitImg6));
    if(SandID.contentEquals("0007"))
        picture.setImageBitmap(getRoundedCornerImage(bitImg7));
    if(SandID.contentEquals("0008"))
        picture.setImageBitmap(getRoundedCornerImage(bitImg8));
    if(SandID.contentEquals("0009"))
        picture.setImageBitmap(getRoundedCornerImage(bitImg9));

    if(SandID.contentEquals("0010"))
        picture.setImageBitmap(getRoundedCornerImage(bitImg10));

    return row;
}

And This is the error :

    First, you are not making use of convertView, you should start like,

    View view = convertView;
if (view == null) {
  // inflate
}

    here’s a blog post that talks about using convertView,

    http://android-er.blogspot.com/2010/06/using-convertview-in-getview-to-make.html

    Second, you should only decode the bitmaps for which you know you will use. so change your method like,

    if(SandID.contentEquals("0001"))
    Bitmap bitImg1 = BitmapFactory.decodeResource(localContext.getResources(), R.drawable.rec0001);
    picture.setImageBitmap(getRoundedCornerImage(bitImg1));
...

    Third, can you decode them once, and have them available outside this method? for example, decode them once in the constructor and store them as instance members in your adapter class, then just use them in getView().

    Fourth, are you recycling your bitmaps? bitmaps are allocated differently than other objects and need to have their recycle() method called on them when you are finished using them. If you can implement the third item above, you can avoid this complexity for the most part, although you should still release them when your activity is stopped, re-allocate them when it’s started.

    There’s lots of good information on SO about Bitmap.recycle() and i’d recommend you spend some time researching it. Explaining the intricacies is beyond what can be accomplished in a post here. Here’s one good SO post covering the topic,

    Bitmap, Bitmap.recycle(), WeakReferences, and Garbage Collection
