java - 列表和适配器

Question

如何从 mGames 的数组中记录用户对他们最喜欢的游戏的投票？

import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.view.ListView;

public class GameListActivity extends ListActivity {

    public String[] mGames = {
        "Age of Empires",
        "Civilization",
        "Minecraft",
        "SimCity"
    };

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

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mGames);
        setListAdapter(adapter);
    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        Log.d("List Item: ", "Clicked!");
    }


    public void sendVote(String game) {
        VoteService.recordVote(game);
    }
}

辅助方法...sendVote()，将记录用户的投票 对于他们最喜欢的游戏...我如何从列表中调用正确的游戏？

Answer 1

您需要实现项目监听器:

public class GameListActivity extends ListActivity implements OnItemClickListener

并在onCreate方法中设置监听器:

ListView list = (ListView) findViewById(R.id.your_list);
list.setListAdapter(adapter);
list.setOnClickListener(this);
