copied!<p>You need to set Buttons property focusable and clickable to false. Because focus and click event is captured by button in current case, not on grid view item. Change your code to following:</p> <pre><code>public class MainActivity extends Activity { public String[] filenames ={"B1","B2","B3","B4","B5","B6"}; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); 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(getBaseContext(), "pic" + (position + 1) + " selected", Toast.LENGTH_SHORT).show(); } }); } public class ButtonAdapter extends BaseAdapter { private Context context; public ButtonAdapter(Context c){ context = c; } public int getCount() { return filenames.length; } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } public View getView(int position, View convertView, ViewGroup parent){ Button btn; if (convertView == null) { btn = new Button(context); btn.setLayoutParams(new GridView.LayoutParams(100, 100)); btn.setPadding(8, 8, 8, 8); btn.setFOcusable(false); btn.setClickable(false); }else { btn = (Button) convertView; } btn.setText(filenames[position]); btn.setTextColor(Color.WHITE); btn.setId(position); return btn; } } } </code></pre>
