Android ListView Item Background Color

I am trying to allow the user to select more than one item. I want to "hig开发者_开发百科hlight" each list item selected so you can tell which item(s) have been selected.

I have tried: view.setBackgroundResource(); view.setBackgroundColor(); view.setBackgroundDrawable();

I havent had any success.

Thannks for the help!

You need to use a custom array adapter , if you are using a listview with only one element you MAY be able to get away with some implemented listview method, but you will have much more flexibility and less headache if you make a custom array adapter instead. You can access all elements in it, each element can have its own onClickListener and everything

If you are passing a String array to the adapter,you can create custom adapter like this and can change background color of a selected item as below:

set the adapter to listview like:

String[] options={"abc","def","ghi","jkl"};

CustomAdapter ca=new CustomAdapter(this,options);    
listView.setAdapter(ca);

and here is the custom adapter class:

public class CustomAdapter extends BaseAdapter
    {
        String items[];
        LayoutInflater mInflater;
        Context context;

    public CustomAdapter(Context context,String[] items)
    {
        this.items=items;
        this.context=context;
        mInflater = LayoutInflater.from(context);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        ViewHolder holder;

        if(convertView==null)
        {
             convertView = mInflater.inflate(R.layout.cutsom_listitem, null);
             holder = new ViewHolder();

             holder.itemName=(TextView)convertView.findViewById(R.id.itemName);

             convertView.setTag(holder);
        }
        else
            holder=(ViewHolder)convertView.getTag();


        String option=items[position];
        holder.itemName.setText(option);

        holder.itemName.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                holder.itemName.setBackgroundColor(Color.parseColor("#FF0000"));  // making selected item red colored
            }
        });

        return convertView;
    }

    @Override
    public int getCount() {
        return items.length;
    }

    @Override
    public Object getItem(int position) {
        return items[position];
    }

    @Override
    public long getItemId(int position) {
        return position;
    }
}

public static class ViewHolder
{
    TextView itemName;
}

u can overwrite setOnTouchListener in your adapter:

view.setOnTouchListener(new OnTouchListener() {

        public boolean onTouch(View v, MotionEvent event) {

            switch(event.getAction()) {

            case MotionEvent.ACTION_DOWN:

                //the bacground when u select item
                v.setBackgroundResource(android.R.color.holo_blue_light);
                break;

            case MotionEvent.ACTION_UP:

                //设置背景为未选中正常状态
            v.setBackgroundResource(android.R.color.background_light);
                break;

            default:
                v.setBackgroundResource(R.drawable.mm_listitem_simple);
                break;

            }
            return false;
        }

you can set diffrence background when your action hanppend.
