Thanks all for the info. I have learned to use Bundle of extras and
GridView but I can't found the error that I am commiting. I have
modified the code:
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
GridView gridview = (GridView) findViewById(R.id.gridview);
gridview.setAdapter(new ImageAdapter(this));
/*g.setOnClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView parent, View v, int
position, long id) {
}
});*/
}
public class ImageAdapter extends BaseAdapter
{
private Context mContext;
private Integer[] mThumbIds = {
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
};
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 position;
}
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)
{
Intent intent = new Intent();
intent.setClass(Editor.this, Rotar.class);
intent.putExtra("imagen",
String.valueOf(position)); <-- I think that position has the position
of the image but I am not sure
startActivity(intent);
finish();
}
});
}
else
{
imageView = (ImageView) convertView;
}
imageView.setImageResource(mThumbIds[position]);
return imageView;
}
}
In the second activity (whose name is "Rotar") I am intenting to
recupere the position that I have selected in the gallery and I am
intenting as the following mode:
Bundle extras = getIntent().getExtras();
if(extras != null)
{
String value = extras.getString("imagen");
imagen = mThumbIds[Integer.getInteger(value)];
}
But when I click an image, the program finish with an error. The
"imagen" and "mThumbids" are declared as private variables in the
first of the class.
Thank again for your answer. A greeting.
