Android Gridview y el botón OnItemclick

Aquí está mi clase buttonAdapter que creo que es precisa:

package com.example.test; import android.content.Context; import android.graphics.Color; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.Button; import android.widget.GridView; public class ButtonAdapter extends BaseAdapter { private Context mContext; public String [] fName = { "File 1", "File 2", "Roflcopters"}; // Gets the context so it can be used later public ButtonAdapter(Context c) { mContext = c; } // Total number of things contained within the adapter public int getCount () { return 8; } // Require for structure, not really used in my code. public Object getItem (int position) { return null; } // Require for structure, not really used in my code. Can be used to get the id of an item in the adapter for manual control. public long getItemId (int position) { return position; } public View getView (int position, View convertView, ViewGroup parent){ Button btn; if (convertView == null) { // if it's not recycled, initialize some attributes btn = new Button (mContext); btn.setLayoutParams (new GridView.LayoutParams (190, 190)); btn.setPadding (1, 1, 1, 1); } else { btn = (Button) convertView; } // btn.setText(filesnames[position]); // filenames is an array of strings //btn.setTextColor (Color.WHITE); //btn.setBackgroundResource (R.drawable.sample_2); //btn.setBackgroundColor (Color.BLACK); btn.setHighlightColor(Color.GREEN); btn.setId (position); return btn; } } 

Aquí está mi clase en casa. No puedo conseguir que el onItemClick funcione. Qué estoy haciendo mal aquí:

• Haga clic en largo Haga clic en span no disparar hasta que se haga clic
• SetOnItemClickListener VS setOnItemSelectedListener en ListView.
• OnItemClickListener no se activa en Android GridView
• Cuando agrego una vista a un elemento ListView, este elemento reacciona ya no correctamente
• El elemento ListView no se puede hacer clic en Android

 package com.example.test; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.Menu; import android.view.View; import android.view.View.OnClickListener; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.GridView; import android.widget.Toast; public class home extends Activity implements OnItemClickListener { public final static String EXTRA_MESSAGE1 = "com.example.text.MESSAGE"; public void onCreate (Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView (R.layout.activity_home); GridView gridview = (GridView) findViewById (R.id.gridview); gridview.setAdapter (new ButtonAdapter (this)); /*gridview.setOnItemClickListener (new OnItemClickListener () { public void onItemClick (AdapterView <?> parent, View v, int position, long id) { Toast.makeText (home.this, "" + position, Toast.LENGTH_LONG).show (); Intent intent = new Intent (this, alarm.class); String message = "Position:" + position; intent.putExtra(EXTRA_MESSAGE1, message); startActivity (intent); } }); * */ } @Override public void onItemClick (AdapterView <?> parent, View v, int position, long id) { Intent intent = new Intent (this, alarm.class); String message = "Position:" + position; intent.putExtra(EXTRA_MESSAGE1, message); startActivity (intent); } } 

El onItemClick no funciona y tampoco lo hace el comentado 'setOnItemClickListener' cuando no se comenta y 'onItemClick' se comenta. ¿Qué estoy haciendo mal?

 public View getView(int position, View convertView, ViewGroup parent) { Button btn; if (convertView == null) { // if it's not recycled, initialize some // attributes btn = new Button (mContext); btn.setLayoutParams(new GridView.LayoutParams(190, 190)); btn.setPadding(1, 1, 1, 1); } else { btn = (Button) convertView; } // btn.setText(filesnames[position]); // filenames is an array of // strings //btn.setTextColor (Color.WHITE); // btn.setBackgroundResource (R.drawable.sample_2); // btn.setBackgroundColor (Color.BLACK); btn.setHighlightColor(Color.GREEN); btn.setId(position); btn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Handle the click here } }); return btn; }
