Android 传输捆绑包并在列表视图中放置对象

Question

我想创建一个列表视图，其中填充了我通过捆绑转移到此活动的项目。我对此完全陌生，所以我不知道如何。这是我到目前为止的位置：

    public class Viewer extends ListActivity { 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    super.onCreate(savedInstanceState);
    Bundle b = getIntent().getExtras();
    final String name = b.getString("name");
    Bundle a = getIntent().getExtras();
    final String number = a.getString("number");

    setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, DETAILS)); 
    ListView lv = getListView(); 
    lv.setTextFilterEnabled(true); 
    lv.setOnItemClickListener(new OnItemClickListener() { 
      public void onItemClick(AdapterView<?> parent, View view, 
          int position, long id) { 
        // When clicked, show a toast with the TextView text 
        Toast.makeText(getApplicationContext(), ((TextView) view).getText(), 
            Toast.LENGTH_SHORT).show(); 
      } 
    }); 
} 
static final String[] DETAILS = new String[] { 
    name, number
  }; 
} 

我想让字符串“name”和“number”出现在列表中，但是当我将它们放在

时出现错误“无法解析为变量”

    static final String[] DETAILS = new String[] { 
    name, number
  }; 
}

Answer 1

在加载类时创建static final String[] DETAILS。但是 final String name = b.getString("name"); 将在稍后调用 onCreate() 时执行。

这应该可行：

static String[] DETAILS;

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    super.onCreate(savedInstanceState);
    Bundle b = getIntent().getExtras();
    final String name = b.getString("name");
    Bundle a = getIntent().getExtras();
    final String number = a.getString("number");


    DETAILS = new String[] {name, number};

    setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, DETAILS)); 
    ListView lv = getListView(); 
    lv.setTextFilterEnabled(true); 
    lv.setOnItemClickListener(new OnItemClickListener() { 
      public void onItemClick(AdapterView<?> parent, View view, 
          int position, long id) { 
        // When clicked, show a toast with the TextView text 
        Toast.makeText(getApplicationContext(), ((TextView) view).getText(), 
            Toast.LENGTH_SHORT).show(); 
      } 
    }); 
}
