Android问卷调查 - 将用户提交的内容保存到内存中

Question

我想知道是否有人知道这个问题的解决方案：我正在使用单选按钮在Android中创建调查问卷，我想知道是否有Android解决方案可以记住单击了哪些单选按钮。例如，我有一个注册和登录，而不是每个用户必须每次点击调查问卷，我怎样才能让Android记住以前提交的按钮。如果我能让Android记住每个用户提交内容，那将是理想的...任何帮助都将受到赞赏，因为我甚至不知道从哪里开始。

以下是我的调查问卷代码：

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_system);
        /*
         * The random generator which generates the data inside each individual
         * string randomly
         */
        randomGenerator = new Random();
        /*
         * The data within each string
         */
        resultsIf1 = new String[] {
                "100% good job",
                "well done" };
        resultsIf2 = new String[] {
                "unlucky",
                        "try again" };

        /*
         * Holding the data for the radio buttons from the xml file
         */
        RadioGroup gender = (RadioGroup) findViewById(R.id.question1);
        gender.setOnCheckedChangeListener(new OnCheckedChangeListener() {
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                // TODO Auto-generated method stub
                switch (checkedId) {
                case R.id.answer1A:
                    ans1 = 1;
                    break;
                case R.id.answer1B:
                    ans1 = 2;
                    break;
                }

            }

        });
        RadioGroup nutrition = (RadioGroup) findViewById(R.id.question2);
        nutrition.setOnCheckedChangeListener(new OnCheckedChangeListener() {
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                // TODO Auto-generated method stub
                switch (checkedId) {
                case R.id.answer2A:
                    ans2 = 1;
                    break;
                case R.id.answer2B:
                    ans2 = 2;
                    break;
                }
            }
        });


        btnSubmitQuiz = (Button) findViewById(R.id.submit);
        btnSubmitQuiz.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                // result answer 1
                if (ans1 == 1 && ans2 == 1) {

                    displayResult(getRandomResult());

                }
                // result answer 2
                else  {

                    displayResult(getRandomResult2());
                }
            }

            /*
             * displays the results once the submit button is pressed
             */

            private void displayResult(String result) {
                Intent i = new Intent("com.example.system.SHOWRESULT");
                i.putExtra("unique_constant", result);
                startActivity(i);
            }


            public String getRandomResult() {
                return resultsIf1[randomGenerator.nextInt(resultsIf1.length)];
            }

            public String getRandomResult2() {
                return resultsIf2[randomGenerator.nextInt(resultsIf2.length)];
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.system, menu);
        return true;
    }
}

您可以使用共享的Shared Preferences或Sqlite DB来存储数据以供日后使用。
