Listview 항목을 문자열 배열에 넣는 방법은 무엇입니까?

Question

앱을 개발 중입니다. 제목으로 listview의 항목을 문자열 배열로, 문자열 배열을 listview로, 목록보기를 문자열 배열로 바꾸는 방법에 대해 설명합니다.

저는 이것을 찾고 있었지만 문자열 배열 항목을 listview에 넣는 것으로 나타났습니다.

미리 감사드립니다.

이 스레드를 명확히하기 위해 listview 항목을 String 배열에 저장하는 방법이 문제입니다.

감사합니다. : 옆에있는 목록보기

은 첫째로 당신이 그렇게처럼 문자열 배열을 만들어에이를 배치 할 내부 항목의 정보는 D

코드

public class DailyPlanTab extends Activity implements OnItemClickListener { 

ListView dailyPlanList; 

ArrayList<DailyManager> taskList = new ArrayList<DailyManager>(); 
DatabaseDailyPlan db; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.dailyplan_layout); 

    dailyPlanList = (ListView) findViewById(R.id.lvDailyPlanList); 
    dailyPlanList.setOnItemClickListener(this); 

    ImageView add = (ImageView) findViewById(R.id.ivDailyPlanAdd); 

    add.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      // TODO Auto-generated method stub 
      Intent newDailyIntent = new Intent(getApplicationContext(), 
        NewDailyPlan.class); 
      startActivity(newDailyIntent); 

     } 
    }); 
} 

@Override 
protected void onResume() { 
    // TODO Auto-generated method stub 
    super.onResume(); 
    taskList.clear(); 

    db = new DatabaseDailyPlan(getApplicationContext()); 
    db.getWritableDatabase(); 

    ArrayList<DailyManager> tempList = db.getTask(); 

    for (int i = 0; i < tempList.size(); i++) { 

     String getTask = tempList.get(i).getDaily_name(); 
     String getDate = tempList.get(i).getDaily_date(); 
     int getId = tempList.get(i).getDaily_id(); 

     DailyManager dm = new DailyManager(); 
     dm.setDaily_name(getTask); 
     dm.setDaily_date(getDate); 
     dm.setDaily_id(getId); 

     taskList.add(dm); 
    } 

    dailyPlanList.setAdapter(new ListAdapter(this)); 
    // db.close(); 

} 

public class ListAdapter extends BaseAdapter { 

    LayoutInflater inflater; 
    ViewHolder viewHolder; 

    public ListAdapter(Context c) { 
     // TODO Auto-generated constructor stub 

     inflater = LayoutInflater.from(c); 
    } 

    @Override 
    public int getCount() { 
     // TODO Auto-generated method stub 
     return taskList.size(); 
    } 

    @Override 
    public Object getItem(int position) { 
     // TODO Auto-generated method stub 
     return position; 
    } 

    @Override 
    public long getItemId(int position) { 
     // TODO Auto-generated method stub 
     return position; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     // TODO Auto-generated method stub 

     if (convertView == null) { 
      convertView = inflater.inflate(R.layout.row_checklist_item, 
        null); 

      viewHolder = new ViewHolder(); 
      viewHolder.taskTitle = (TextView) convertView 
        .findViewById(R.id.tvCheckListItem); 
      convertView.setTag(viewHolder); 

     } else { 
      viewHolder = (ViewHolder) convertView.getTag(); 
     } 

     viewHolder.taskTitle.setText("" 
       + taskList.get(position).getDaily_name()); 

     return convertView; 
    } 
} 

public class ViewHolder { 

    TextView taskTitle, taskDate; 
} 

@Override 
public void onItemClick(AdapterView<?> arg0, View arg1, int position, 
     long arg3) { 
    // TODO Auto-generated method stub 

    int taskId = taskList.get(position).getDaily_id(); 
    String taskName = taskList.get(position).getDaily_name(); 
    String taskDate = taskList.get(position).getDaily_date(); 

    Intent newPlan = new Intent(getApplicationContext(), DailyPlan.class); 
    newPlan.putExtra("task_id", taskId); 
    newPlan.putExtra("task_name", taskName); 

    startActivity(newPlan); 
} 

입니다 활동 선언 상단 :

private String[] stringArray = new String[listView.getCount()]; 

그러면 listView.getCount()를 사용하여 목록에있는 항목의 수를 확인한 다음 목록을 반복하고 이전에 만든 배열에 모든 값을 추가 할 수 있습니다. 이렇게 할 수 있습니다 :

for(int i=0; i < listView.getCount(); i++) 
{ 
    View v = list.getChildAt(i); 
    TextView tv= (TextView) v.findViewById(R.id.item); 
    stringArray[i] = tv.getText(); 
} 

희망이 도움이 작품은! 그렇지 않으면 알려주세요.

Answer 2

먼저 당신은 당신의 열 의 길이에 의해 배열을 만들고

string[] selected_item = new string[listView.SelectedItems.Count]; 
    for (int i = 0; i < selected_item.Length; i++) 
    { 
     selected_item[i] = listView.SelectedItems[i].Text; 
    }
