Android 如何制作历史测试列表？

我想让应用程序与数学问题和测试后的结果保存在共享的首选项，并将与最后十个测试的活动。 我知道如何提问，我知道如何专注于活动，我知道如何在共享偏好中保存数据，以及如何从共享偏好中获取数据，但我不知道如何列出最后十项测试，我尝试进行4项测试，我是这样做的：

                sharedL1 = getSharedPreferences("List", Context.MODE_PRIVATE);
                edit = sharedL1.edit();
                edit.putString("List","Easy Game");
                edit.apply();

  sharedL1 = getSharedPreferences("List2", Context.MODE_PRIVATE);
        edit = sharedL1.edit();
        edit.putString("List2",L1T.getText().toString());
        edit.apply();

        sharedL1 = getSharedPreferences("List3", Context.MODE_PRIVATE);
        edit = sharedL1.edit();
        edit.putString("List3",L2T.getText().toString());
        edit.apply();

        sharedL1 = getSharedPreferences("List4", Context.MODE_PRIVATE);
        edit = sharedL1.edit();
        edit.putString("List4",L3T.getText().toString());
        edit.apply();

            sharedL1 = getSharedPreferences("List", Context.MODE_PRIVATE);
        L1T.setText(sharedL1.getString("List",""));

        sharedL1 = getSharedPreferences("List2", Context.MODE_PRIVATE);
        L2T.setText(sharedL1.getString("List2",""));

        sharedL1 = getSharedPreferences("List3", Context.MODE_PRIVATE);
        L3T.setText(sharedL1.getString("List3",""));

        sharedL1 = getSharedPreferences("List4", Context.MODE_PRIVATE);
        L4T.setText(sharedL1.getString("List4",""));

首先，在测试后，我保存结果如下：

                sharedL1 = getSharedPreferences("List", Context.MODE_PRIVATE);
                edit = sharedL1.edit();
                edit.putString("List","Easy Game");
                edit.apply();

  sharedL1 = getSharedPreferences("List2", Context.MODE_PRIVATE);
        edit = sharedL1.edit();
        edit.putString("List2",L1T.getText().toString());
        edit.apply();

        sharedL1 = getSharedPreferences("List3", Context.MODE_PRIVATE);
        edit = sharedL1.edit();
        edit.putString("List3",L2T.getText().toString());
        edit.apply();

        sharedL1 = getSharedPreferences("List4", Context.MODE_PRIVATE);
        edit = sharedL1.edit();
        edit.putString("List4",L3T.getText().toString());
        edit.apply();

            sharedL1 = getSharedPreferences("List", Context.MODE_PRIVATE);
        L1T.setText(sharedL1.getString("List",""));

        sharedL1 = getSharedPreferences("List2", Context.MODE_PRIVATE);
        L2T.setText(sharedL1.getString("List2",""));

        sharedL1 = getSharedPreferences("List3", Context.MODE_PRIVATE);
        L3T.setText(sharedL1.getString("List3",""));

        sharedL1 = getSharedPreferences("List4", Context.MODE_PRIVATE);
        L4T.setText(sharedL1.getString("List4",""));

在测试活动中，在放置保存的数据之前，我从其他测试中获取数据，如下所示：

                sharedL1 = getSharedPreferences("List", Context.MODE_PRIVATE);
                edit = sharedL1.edit();
                edit.putString("List","Easy Game");
                edit.apply();

  sharedL1 = getSharedPreferences("List2", Context.MODE_PRIVATE);
        edit = sharedL1.edit();
        edit.putString("List2",L1T.getText().toString());
        edit.apply();

        sharedL1 = getSharedPreferences("List3", Context.MODE_PRIVATE);
        edit = sharedL1.edit();
        edit.putString("List3",L2T.getText().toString());
        edit.apply();

        sharedL1 = getSharedPreferences("List4", Context.MODE_PRIVATE);
        edit = sharedL1.edit();
        edit.putString("List4",L3T.getText().toString());
        edit.apply();

            sharedL1 = getSharedPreferences("List", Context.MODE_PRIVATE);
        L1T.setText(sharedL1.getString("List",""));

        sharedL1 = getSharedPreferences("List2", Context.MODE_PRIVATE);
        L2T.setText(sharedL1.getString("List2",""));

        sharedL1 = getSharedPreferences("List3", Context.MODE_PRIVATE);
        L3T.setText(sharedL1.getString("List3",""));

        sharedL1 = getSharedPreferences("List4", Context.MODE_PRIVATE);
        L4T.setText(sharedL1.getString("List4",""));

并将数据如下所示：

                sharedL1 = getSharedPreferences("List", Context.MODE_PRIVATE);
                edit = sharedL1.edit();
                edit.putString("List","Easy Game");
                edit.apply();

  sharedL1 = getSharedPreferences("List2", Context.MODE_PRIVATE);
        edit = sharedL1.edit();
        edit.putString("List2",L1T.getText().toString());
        edit.apply();

        sharedL1 = getSharedPreferences("List3", Context.MODE_PRIVATE);
        edit = sharedL1.edit();
        edit.putString("List3",L2T.getText().toString());
        edit.apply();

        sharedL1 = getSharedPreferences("List4", Context.MODE_PRIVATE);
        edit = sharedL1.edit();
        edit.putString("List4",L3T.getText().toString());
        edit.apply();

            sharedL1 = getSharedPreferences("List", Context.MODE_PRIVATE);
        L1T.setText(sharedL1.getString("List",""));

        sharedL1 = getSharedPreferences("List2", Context.MODE_PRIVATE);
        L2T.setText(sharedL1.getString("List2",""));

        sharedL1 = getSharedPreferences("List3", Context.MODE_PRIVATE);
        L3T.setText(sharedL1.getString("List3",""));

        sharedL1 = getSharedPreferences("List4", Context.MODE_PRIVATE);
        L4T.setText(sharedL1.getString("List4",""));

请帮我完成这项工作：）

提前谢谢
