   android.widget.AdapterView.OnItemClickListener;
public class GridViewExampleActivity extends Activity {
 /** Called when the activity is first created. */

private GridviewAdapter mAdapter;
private ArrayList<String> listCountry;
private ArrayList<Integer> listFlag;

private GridView gridView;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    // prepared arraylist and passed it to the Adapter class
    mAdapter = new GridviewAdapter(this,listCountry, listFlag);

推荐答案

您可以基于位置使用意图打开活动

You can open activity using intent based on position

 gridView.setOnItemClickListener(new OnItemClickListener()
            {
                @Override
                public void onItemClick(AdapterView<?> arg0, View arg1, int position,
                                        long arg3) {
                    if(position==1) {
                        Intent intent = new Intent(GridViewExampleActivity.this, IndiaActivity.class);
                        startActivity(intent);
                    }
                    else if(position==2)
                    {
                        Intent intent = new Intent(GridViewExampleActivity.this, BrazilActivity.class);
                        startActivity(intent);

                    }
                    Toast.makeText(GridViewExampleActivity.this, mAdapter.getItem(position), Toast.LENGTH_SHORT).show();
                }
            });
