I am using the following code to do things with gridview(slightly
modified from
http://developer.android.com/resources/tutorials/views/hello-gridview.html).
I want to replace the onClicklistener and the onClick() method with
their "touch" equivalents i.e. touchlistener and onTouch() so that
when i touch an element in the gridview the image of the element
changes and a double touch on the same element takes it back to the
orginal state.
How do I do this? I can't get my code to do this. The clicklistener
works to some extent but the touch isn't. Please help.
public class ImageAdapter extends BaseAdapter {
private Context mContext;
public ImageAdapter(Context c) {
mContext = c;
}
public int getCount() {
return mThumbIds.length;
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
// create a new ImageView for each item referenced by the Adapter
public View getView(int position, View convertView, ViewGroup parent)
{
ImageView imageView;
if (convertView == null) { // if it's not recycled, initialize
some attributes
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(8, 8, 8, 8);
imageView.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View view)
{
if(position==0)
{
//do this
}
else
{
//do this
}
}
});
} else {
imageView = (ImageView) convertView;
}
imageView.setImageResource(mThumbIds[position]);
return imageView;
}
// references to our images
private Integer[] mThumbIds = {
R.drawable.sample_2, R.drawable.sample_3,
R.drawable.sample_4, R.drawable.sample_5,
R.drawable.sample_6, R.drawable.sample_7,
R.drawable.sample_0, R.drawable.sample_1,
R.drawable.sample_2, R.drawable.sample_3,
R.drawable.sample_4, R.drawable.sample_5,
R.drawable.sample_6, R.drawable.sample_7,
R.drawable.sample_0, R.drawable.sample_1,
R.drawable.sample_2, R.drawable.sample_3,
R.drawable.sample_4, R.drawable.sample_5,
R.drawable.sample_6, R.drawable.sample_7
};
}
