[android-developers] Re: Image Edition
Thank for you respond.
I am already using intent for moving from one activity to another and
I have declared it in the androidmanifest. The code that I am using is
the following:
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Gallery g = (Gallery) findViewById(R.id.Gallery);
g.setAdapter(new ImageAdapter(this));
g.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView parent, View v, int
position, long id)
{
//Toast.makeText(Editor.this, + position,
Toast.LENGTH_SHORT).show();
}
});
ImageButton abrir = (ImageButton)
findViewById(R.id.ImageButton01);
abrir.setOnClickListener(abrirImagen);
ImageButton cerrar = (ImageButton)
findViewById(R.id.ImageButton01);
cerrar.setOnClickListener(cerrarPrograma);
}
/*private OnClickListener abrirImagen = new OnClickListener()
{
public void onClick(View v)
{
Intent intent = new Intent();
intent.setClass(Editor.this, Rotar.class);
startActivity(intent);
finish();
}
};*/
private OnItemClickListener seleccionImagen = new
OnItemClickListener()
{
public void onItemClick(AdapterView parent, View v, int
position, long id)
{
Intent intent = new Intent();
intent.setClass(Editor.this, Rotar.class);
startActivity(intent);
finish();
}
};
The commented function is where I use the botton and the non-commented
funcion is where I want to go to another activity. If someone wants I
can put the complete code but I think that there isn't neccesary. As
you can see I use intents for open the other activity but I don't know
how I can pass the selected image.
Greetings.

You might use Bundle of extras to pass information from one activity to
another activity.

[android-developers] Re: Image Edition
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.
