ListView的显示包含在另一个ListView中

Question

我有一个问题，我无法解决它。我想创建投票应用程序。我创建了2个类： - 包含用户名，问题以及Choice的一个ArrayList的投票 - 选项包含选项及其ID。

我想在主页上显示不同选择的问题列表（ArrayList）。我设法显示这个列表，但是我对类Poll的ArrayList有问题，因为只有第一项显示，但我想显示所有选择列表。

POLL CLASS

public class Poll{ 
    String question; 
    String forename; 
    ArrayList<Choice> list_choices; 


    public String getQuestion() { 
     return question; 
    } 
    public void setQuestion(String question) { 
     this.question = question; 
    } 
    public String getForename() { 
     return forename; 
    } 
    public void setForename(String forename) { 
     this.forename = forename; 
    } 

    public ArrayList<Choice> getListChoice() { 
     return list_choices; 
    } 
    public void setListChoice(ArrayList<Choice> list_choices) { 
     this.list_choices = list_choices; 
    } 
} 

CHOICE CLASS

public class Choice { 
    int id; 
    String choice; 

    public int getId() { 
     return id; 
    } 
    public void setId(int id) { 
     this.id = id; 
    } 
    public String getChoice() { 
     return choice; 
    } 
    public void setChoice(String choice) { 
     this.choice = choice; 
    } 

}

    ArrayList<Poll> listPolls; 
    LayoutInflater layoutInflater;

    public CustomListAdapter(Context context,ArrayList<Poll> listPolls) { 
     this.listPolls = listPolls;

       //tagguer notre objet pour pouvoir le récupérer à la prochaine mise à jour graphique. 
      arg1.setTag(holder); 
     } 
     else

活动，其显示的ArrayList

    ListView lv; 

    @Override

     super.onCreate(savedInstanceState); 

     setContentView(R.layout.debugg); 
     //Récuperation de ListView crée 

     lv = (ListView) findViewById(R.id.listView1); 


     ArrayList<Choice> list_choice = new ArrayList<Choice>(); 
     Choice choix = new Choice(); 
     choix.setChoice("choix 1"); 
     list_choice.add(choix); 
     choix = new Choice(); 
     choix.setChoice("choix 2"); 
     list_choice.add(choix); 


     ArrayList<Poll> resultats = new ArrayList<Poll>(); 
     Poll newsData = new Poll(); 
     newsData.setListChoice(list_choice); 
     newsData.setForename("Paul"); 
     newsData.setQuestion("Question 1"); 
     resultats.add(newsData); 
     newsData = new Poll(); 
     newsData.setListChoice(list_choice); 
     newsData.setForename("Laetitia"); 
     newsData.setQuestion("Question 2"); 
     resultats.add(newsData); 
     lv.setAdapter(new CustomListAdapter(this, resultats)); 
    }

Answer 1

人，一个和ORI杜松子酒的解决方案是：

设置你的父母ListView项目WRAP_CONTENT身高。接下来，设置您包含的ListView项目的固定高度。然后在getView()方法中设置你包含的高度ListView的高度等于parent_array_list.size() * child_list_view_item_height。这可能对你有所帮助。

代码示例：

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, (int) (listPolls.size() * TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, child_list_view_item_height, displayMetrics))); 
holder.ChoiceView.setLayoutParams(params);
