我想建立与单独显示和问题的调查问卷类型的应用程序，当用户提交一个答案，点击数据被存储在上面一个TextView的按钮和问题要问在哪里这个问题的答案存储在一个问题一个新的TextView。我有困难得到改变下一个问题的问题。

I want to build a questionnaire type app with questions that show up individually and when a user submits an answer and clicks the button the data is stored in a textView above and the question goes to the next question where that answer is stored in a new textView. I am having difficulty getting the question to change to the next question.

myTexts[0]=findViewById(R.id.question1);
myTexts[1]=findViewById(R.id.question2);

 myTexts[questionNumber].setText(mEdit.getText().toString());
 questionNumber++;

推荐答案

要改变你应该有字符串或字符串列表的数组，可以容纳所有的问题，只要点击按钮，答案存储在问题TextView中要加载从字符串数组或列表持有该问题，下一个问题。

To change question you should have array of String or List of String that can hold all the question and as soon as button is clicked and the answer is stored in the TextView you will load the next question from that array or List of String that is holding the questions.

 String [] questions;
 int numberOfQuestions = 2;

，然后在onCreate（）方法

and then in onCreate() method

 questions=new String[numberOfQuestions];//numberOfQuestion refers to integer that holds total number of questions
 questions[0]="This is first question?";
 questions[1]="This is second question?";

和现在你view.onClickListener

and now in your view.onClickListener

mButton.setOnClickListener(
new View.OnClickListener()
   {
        public void onClick(View view)
        {

            myTexts[questionNumber].setText(mEdit.getText().toString());
            questionNumber++;   
            //here you will have to load the next question 
            if(questionNumber < numberOfQuestions)
                questionTextViewHolder.setText(questions[questionNumber]);
            else
                Toast.makeText(menu.this,"No more questions!",Toast.LENGTHLONG).show();

            //Note one thing that your questionNumber variable should not increase myTexts length or questions length because if it does you will get  exception
        }
    });

questionTextViewHolder是TextView的您在其中显示的问题就是要回答，你将与你的TextView您在其中显示的问题，以取代questionTextViewHolder！
类名菜单首字母应该大写，如果你遵循的编码约定。

questionTextViewHolder is the TextView in which you are displaying the question that is to be answered, you will have to replace "questionTextViewHolder " with your textview in which you are displaying the questions ! Class name menu starting letter should be capital if you follow the coding conventions.
