Question

I’m not sure if the title is ok but i’ll try to explain it better.

I want to show a grid in my layout. To do that, i’m using a custom ArrayAdapter.
I don’t how to set the onClickListener to each item…

The layout contains a label, to display a name, and a gridview.

This is my Activity:

public class Sala extends Activity{
GridView gridView;
TextView label_name;

ArrayList<String> lista_opciones = new ArrayList<String>();  

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.layout_sala);
    //Refresh the name in the label
    Bundle bundle=getIntent().getExtras();
    String name= bundle.getString("name");
    label_name= (TextView) findViewById(R.id.label_name);
    label_name.setText(name);

    //Loading array
    lista_op.add("Op 1");  
    lista_op.add("Op 2");  
    lista_op.add("Op 3");  
    lista_op.add("Op 4"); 

    //AdaptadorOpciones
    ArrayAdapterOpciones mAdapter = new ArrayAdapterOptions(this,lista_op);  

    //Set the customAdapter to the grid
    gridView = (GridView) findViewById(R.id.grid); 
    gridView.setAdapter(mAdapter);  
}

}

Witch methods should I override to implement the onClickListener in each item?

Answer 1

impllement setOnItemClickListener for gridview item click:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.layout_sala);
    //Refresh the name in the label
    Bundle bundle=getIntent().getExtras();
    String name= bundle.getString("name");
    label_name= (TextView) findViewById(R.id.label_name);
    label_name.setText(name);

    //Loading array
    lista_op.add("Op 1");  
    lista_op.add("Op 2");  
    lista_op.add("Op 3");  
    lista_op.add("Op 4"); 

    //AdaptadorOpciones
    ArrayAdapterOpciones mAdapter = new ArrayAdapterOptions(this,lista_op);  

    //Set the customAdapter to the grid
    gridView = (GridView) findViewById(R.id.grid); 
    gridView.setAdapter(mAdapter);  
    gridView.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View v, int position, long id) {

                //Do stuff here
            }
        });
}
