我想讓這個gridview可點擊。一切正常，但最後一個單元格。當我點擊最後一個單元格，即第8個單元格時，程序崩潰。任何有關它崩潰的建議都會有幫助。GridView可點擊
public class MainView extends Activity {
\t
\t ImageView back, home, site;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
\t setContentView(R.layout.mainview);
GridView gridView = (GridView)findViewById(R.id.gridview);
gridView.setAdapter(new MyAdapter(this));
gridView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
\t
\t Intent myIntent = null;
if(position == 0){
myIntent = new Intent(v.getContext(), TheShow.class);
}
if(position == 1){
myIntent = new Intent(v.getContext(), Exhibitor.class);
}
if(position ==2){
myIntent = new Intent(v.getContext(), Visitor.class);
}
if(position ==3){
myIntent = new Intent(v.getContext(), Conference.class);
}
if(position ==4){
myIntent = new Intent(v.getContext(), ContactUs.class);
}
if(position == 5){
\t myIntent = new Intent(v.getContext(), VisitorReg.class);
}
if(position == 6){
\t myIntent = new Intent(v.getContext(), ExhibitorReg.class);
}
if(position == 7){
\t Toast.makeText(getApplicationContext(), "Pending", 4000).show();
}
startActivity(myIntent); \t
\t
}
});
}
