當(dāng)我點(diǎn)擊一個(gè)項(xiàng)目時(shí)，我需要更新我的 gridView。我嘗試了很多東西，但沒(méi)有任何效果。我的活動(dòng)有以下代碼：public class GameActivity extends AppCompatActivity implements IGameView{public GridGame _gridGame = new GridGame();public GamePresenter _presenter = new GamePresenter(this, _gridGame);public ImageAdapter _imageAdapter = new ImageAdapter(this, _gridGame);@Overridepublic boolean onCreateOptionsMenu(Menu menu) {    // Inflate the menu; this adds items to the action bar if it is present.    getMenuInflater().inflate(R.menu.main, menu);    return true;}@Overridepublic boolean onOptionsItemSelected(MenuItem item) {    // Handle action bar item clicks here. The action bar will    // automatically handle clicks on the Home/Up button, so long    // as you specify a parent activity in AndroidManifest.xml.    int id = item.getItemId();    //noinspection SimplifiableIfStatement    if (id == R.id.action_help) {        Intent intent = new Intent(this, HelpActivity.class);        startActivity(intent);        return true;    }    return super.onOptionsItemSelected(item);}@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_game);    final Context context = this;    final GridView gridview = (GridView) findViewById(R.id.gridview);    gridview.setAdapter(_imageAdapter);    gridview.setOnItemClickListener(new AdapterView.OnItemClickListener() {        public void onItemClick(AdapterView<?> parent, View v,                                int position, long id) {            _presenter.addPawn(position);            _imageAdapter.update(position, _presenter.actualPlayer);            Toast.makeText(context, "" + position,Toast.LENGTH_SHORT).show();        }    });}當(dāng)我單擊一個(gè)正方形（gridview 上的項(xiàng)目）時(shí)，我希望視圖更新顯示其他圖像而不是正方形。當(dāng)我在 ImageAdapter 上調(diào)用 update 方法但視圖不更新時(shí)，更新完成。
