Question

我正在尝试使用姓名和数字填充两行列表。

我已完成此部分，但我想在点击特定项目时拨打这些数字。

我知道单行列表的这种方法，但我发现两行很难。

import android.widget.ListView;
import android.widget.SimpleAdapter;
import java.util.ArrayList;
import java.util.HashMap;


public class MainActivity extends ListActivity {
    private SimpleAdapter sa;
    ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();
    ListView lv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.list1);
        lv= (ListView) findViewById(R.id.listView);
        HashMap<String, String> item;


        for (int
                     i = 0; i < nameandmubers.length; i++) {
            item = new
                    HashMap<String, String>();
            item.put("line1",
                    nameandmubers[i][0]);
            item.put("line2",
                    nameandmubers[i][1]);
            list.add(item);
        }
        sa = new SimpleAdapter(this, list, R.layout.list1,
                new String[]{"line1", "line2"},
                new int[]{R.id.text1, R.id.text2});

        setListAdapter(sa);
       

    }

    private String[][] nameandmubers = {{"mehadi", "0123565"},
            {"sagor", "01615"}, {"ovi", "2356565"}, {"hamidul", "25341"},

试试这个！

  lv.setOnItemClickListener(new OnItemClickListener()
  {
  @Override 
  public void onItemClick(AdapterView<?> arg0, View arg1,int position, long arg3)
 { 
    String mynumber= //use something like a mutlidimensional array eg. String with value as 'position'
Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse(mynumber));
startActivity(intent);
}

这可能会有所帮助！
