ListFragment를 사용하여 ListView에 대한 객체 배열 만들기

Question

간단한 ListView에 객체 목록을 구현하는 데 문제가있는 것처럼 보입니다.

다음은 각 목록 요소에 대한 내 개체 클래스입니다. package com.example.android.fragments;

package com.example.android.fragments; 

public class ListObject { 
    public String objectname; //name of schedule 
    public boolean[] Days = { 
      false, //monday 
      false, //tuesday 
      false, //and soforth 
      false, 
      false, 
      false, 
      false}; 

    public int starthour, startminute, stophour, stopminute; //times from TimePicker 
    public boolean vibrate; 

    public ListObject() 
    { 
     objectname = null; //if doesnt work, do objectname = ""; 
     vibrate = false; 
     starthour = 8; 
     startminute = 0; 
     stophour = 15; 
     stopminute = 0; 
    } 

    public ListObject(String name, boolean[] newdays, boolean vib, int a, int b, int c, int d) 
    { 
     objectname = name; 
     Days = newdays; 
     vibrate = vib; 
     starthour = a; 
     startminute = b; 
     stophour = c; 
     stopminute = d; 
    } 

    @Override 
    public String toString() 
    { 
     String startampm = "am"; 
     String stopampm = "am"; 
     if (starthour > 11) //turns into am/pm 
     { 
      startampm = "pm"; 
      starthour -= 12; 
     } 
     if (stophour > 11) //turns into am/pm 
     { 
      stopampm = "pm"; 
      stophour -= 12; 
     } 

     String daysstring = null ; //initializes string representing days activated 
     for(int i = 0; i < 7; i++) //add into string the correct days 
     { 
      if (Days[i] == true) 
      { 
       if(i == 0) 
        daysstring += "M, "; 
       else if (i == 1) 
        daysstring += "Tu, "; 
       else if (i == 2) 
        daysstring += "W, "; 
       else if (i == 3) 
        daysstring += "Th, "; 
       else if (i == 4) 
        daysstring += "F, "; 
       else if (i == 5) 
        daysstring += "Sa, "; 
       else 
        daysstring += "Su, "; 
      } 
     } 
     daysstring = daysstring.substring(0, daysstring.length() - 3); //removes the last ', ' 
     daysstring += ": "; 

     String timestring = 
       starthour + ":" + startminute + " " + startampm + " - " + 
       stophour + ":" + stopminute + " " + stopampm; 

     return objectname + "\n" + daysstring + timestring; 
    } 

}

package com.example.android.fragments; 

import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 
import android.support.v4.app.FragmentTransaction; 

public class MainActivity extends FragmentActivity 
     implements MainListFragment.OnListSelectedListener { 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.mainlayout); 

     // Check whether the activity is using the layout version with 
     // the fragment_container FrameLayout. If so, we must add the first fragment 
     if (findViewById(R.id.fragment_container) != null) { //meaning, if using phone version 

      // However, if we're being restored from a previous state, 
      // then we don't need to do anything and should return or else 
      // we could end up with overlapping fragments. 
      if (savedInstanceState != null) { 
       return; 
      } 

      // Create an instance of ExampleFragment 
      MainListFragment firstFragment = new MainListFragment(); 

      // In case this activity was started with special instructions from an Intent, 
      // pass the Intent's extras to the fragment as arguments 
      firstFragment.setArguments(getIntent().getExtras()); 



      // Add the fragment to the 'fragment_container' FrameLayout 
      getSupportFragmentManager().beginTransaction() 
        .add(R.id.fragment_container, firstFragment).commit(); 
     } 
    } 

    public void onArticleSelected(int position) { 

     // Capture the article fragment from the activity layout 
     InfoFragment articleFrag = (InfoFragment) 
       getSupportFragmentManager().findFragmentById(R.id.article_fragment); //article_fragment exists in layout-large 

     if (articleFrag != null) { 
      // If article frag is available, we're in two-pane layout... 

      // Call a method in the ArticleFragment to update its content 
      articleFrag.updateArticleView(position); 

     } else { 
      // phone layout - swap frags 

      // Create fragment and give it an argument for the selected article 
      InfoFragment newFragment = new InfoFragment(); 
      Bundle args = new Bundle(); 
      args.putInt(InfoFragment.ARG_POSITION, position); 
      newFragment.setArguments(args); 
      FragmentTransaction transaction = getSupportFragmentManager().beginTransaction(); 

      // Replace whatever is in the fragment_container view with this fragment, 
      // and add the transaction to the back stack so the user can navigate back 
      transaction.replace(R.id.fragment_container, newFragment); 
      transaction.addToBackStack(null); 

      // Commit the transaction 
      transaction.commit(); 
     } 
    } 
} 

인 mainlayout 할 수있는 레이아웃을 설정하는 문제이고, 응용 프로그램의 시작 오픈 할 예정이다 여기 내 ListFragment에, 단순히 객체의 3을 생성하고 mainlistview의 ListView에 ID를 가지고 내 listlayout.xml에 정의 된 목록보기에 넣어 수 없습니다

당신은 내가 주석 한 볼 수 있습니다 이전에 객체 클래스를 사용하여 toString()을 재정의했는데, 어디에서 잘못 되었습니까? 그리고 이것을 구현하는 가장 좋은 방법은 무엇입니까? 이 결국 문자열을 표시하기 때문에 결국 더 나은 listview 만들려면 원하는 및 각 개체에 대한 확인란을 다른 크기와 색이 지정된 텍스트를 원하는하지만 지금은이 작업을 얻으려고.

Answer 1

ArrayAdapter를 확장하는 사용자 지정 어댑터를 만들면됩니다. 여기에 예제가 있습니다. http://devtut.wordpress.com/2011/06/09/custom-arrayadapter-for-a-listview-android/
