  1. POAndroid: Change Button background in ListView Row with onClick
    text
    copied!<p>My rows contain a button that has its own click listener set in my adapter's getView. I'm able to distinguish between my button clicks and the actual row item clicks using android:descendantFocusability="blocksDescendants" in the row's parent.</p> <p>When I click on a button it sets the button background properly, my problem is as I scroll through the list its setting it for different rows as well. I assume theirs an issue somewhere with views recycling. </p> <p>Here's my code:</p> <pre><code>@Override public View getView(int position, View convertView, ViewGroup parent){ if(convertView == null){ holder = new ViewHolder(); convertView = inflater.inflate(R.layout.todays_sales_favorite_row, null); holder.favCatBtn = (Button)convertView.findViewById(R.id.favCatBtn); convertView.setTag(holder); } else { holder = (ViewHolder)convertView.getTag(); } holder.favCatBtn.setTag(position); holder.favCatBtn.setOnClickListener(this); return convertView; } @Override public void onClick(View v) { int pos = (Integer) v.getTag(); Log.d(TAG, "Button row pos click: " + pos); RelativeLayout rl = (RelativeLayout)v.getParent(); holder.favCatBtn = (Button)rl.getChildAt(0); holder.favCatBtn.setBackgroundResource(R.drawable.icon_yellow_star_large); } </code></pre> <p>So if i click on the button at row position 1 the button background changes as it should. But then as i scroll down the list random other buttons are getting set as well. Then sometimes when I scroll back up to position 1 the button background reverts back to the original again.</p> <p>What am I missing here? I know I'm right there its just something minor I'm not doing. </p>
