我想展示几个ListView视图,每个视图都有对应的标题LinearLayout

我有一个LinearLayout,我膨胀一个视图以填充标题ListView并将该视图添加到LinearLayout循环中,但只出现一个标题和列表(第一个)。

我希望包含标题和列表视图的视图出现的次数与 for 循环重复的次数一样多。

让我给你看一下代码:

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

//fragment_history: a layout with a LinearLayout inside called "main"

      View fragmentHistory = inflater.inflate(R.layout.fragment_history, container, false);

//I want to show a date, and all the transactions accomplished that date. With this two arrays, I pretend to loop by day, show the date as title and show the transactions of that day in the listview.

        allExpenses = dataExpenses.getAllExpenses();
        allDatesExpenses = dataExpenses.getAllDates();

// The LinearLayout inside the fragmentHistory layout 

        LinearLayout mainLayout = (LinearLayout) fragmentHistory.findViewById(R.id.main);       
        LayoutInflater layoutInflater = (LayoutInflater) this.context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

// I made a for loop, and I have two different dates. Two transactions in the first date, and one in the second day. But only the two transactions are been shown.

        for(int x = 0, y = allDatesExpenses.size(); x < y; x++){

            View view = layoutInflater.inflate(R.layout.layout_title, null);        

            Expense expense = allDatesExpenses.get(x);

            TextView text = Font.useHandelGotic(this.context, (TextView) view.findViewById(R.id.textViewTitleDate)) ;
    text.setText(expense.getDateExpense());  

            ListView listview = (ListView) view.findViewById(android.R.id.list);

            ArrayList<Expense> expensesByDate = (ArrayList<Expense>) dataExpenses.getExpensesByDate(expense.getDateExpense());
            listview.setDivider(null);
            listview.setAdapter(new AdapterTransaction(this.context, expensesByDate));

            mainLayout.addView(view);

        }       
        return fragmentHistory;
    }

根据您提供的信息,我猜您LinearLayout已设置为水平(默认),因此您的所有标题/列表视图实际上都已添加,但您看不到它们,因为它们不在一边。通过添加来解决这个问题

android:orientation="vertical"

到您的LinearLayoutXML 标记。

如果这不是问题,请发布相关的 XML 布局。
