Question

我希望显示多个ListView次观看，每次观看都在LinearLayout中显示相应的标题。

我有一个LinearLayout，我通过一个视图来填充标题并ListView并将该视图添加到循环中的LinearLayout，但只显示一个标题和列表（第一个）。

我希望包含标题和列表视图的视图与for循环重复次数一样多出现。

让我告诉你代码：

    @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，我猜您的LinearLayout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无法看到它们，因为它们离开了一边。通过添加

修复此问题

android:orientation="vertical"

到您的LinearLayout XML标记。

如果这不是问题，请发布相关的XML布局。
