我有一個Java類和兩個XML文件,它們基本上只是一個並排的listView,它有一些值。我想在每個列表視圖上方放置一個標題或一個文本視圖(它們應該保持並排),但是每次嘗試添加textView時,整個項目都會變得混亂,並且下面的聯機指令無法實現標題。在2列表視圖上添加標題/ TextView
public class Leaderboard extends AppCompatActivity {
private ListView UsernameList;
private ListView ScoreList;
LocalDatabase localDatabase;
/** Called when the activity is first created */
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_leaderboard);
ArrayAdapter<String> listAdapter;
ArrayAdapter<Integer> list2Adapter;
//Find the ListView resources
UsernameList = (ListView) findViewById(R.id.UsernameList);
ScoreList = (ListView) findViewById(R.id.ScoreList);
//Create and populate the list of usernames.
//This is where the information from the Database would need to be entered. and the String[] removed
String[] usernames = new String[]{"Andy", "Marie", "George"};
ArrayList<String> usernameList = new ArrayList<String>();
usernameList.addAll(Arrays.asList(usernames));
//Create and populate the list of scores
//This is where the information from the Database would need to be entered. and the Integer[] removed
Integer[] scores = new Integer[]{7, 4, 1};
ArrayList<Integer> scoreList = new ArrayList<Integer>();
scoreList.addAll(Arrays.asList(scores));
//adds the users details to the leaderboard
localDatabase = new LocalDatabase(this);
Contact contact = localDatabase.getLoggedInUser();
//Set a string to have the value of the users name.
String s = contact.name;
//Create Array Adapter using the username list
listAdapter = new ArrayAdapter<String>(this, R.layout.activity_row, usernameList);
//Add more users
listAdapter.add(s);
//Set the Array Adapter as the ListView's adapter
UsernameList.setAdapter(listAdapter);
//Create Array Adapter using the username list
list2Adapter = new ArrayAdapter<Integer>(this, R.layout.activity_row, scoreList);
//Add more users
list2Adapter.add(0);
//Set the Array Adapter as the ListView's adapter
ScoreList.setAdapter(list2Adapter);
}
}
然後兩個XML文件
