在 Android 按钮和 textview 上显示数组

Question

我目前正在做 Android 多项测验游戏，但我对如何在 TextView 上显示所有六个问题和在按钮上显示四个答案有点困惑？另外，我不确定如何在 Android 中匹配正确/错误的答案（因为它涉及 Android 语法）。

PS：当玩家按下按钮时，错误玩家的正确是否会移动到下一个新问题+答案，如果我想将问题和答案存储在txt文件中，是否可以？

这是我到目前为止所做的......

public class play extends Activity 实现 OnClickListener {

private int correctanswers;
private TextView questionstextview;
private TextView questionnumber;
private TextView playerfeedback;
private int totalanswer;
private int score;
private List<Question> QuestionList;

Button answer1,answer2,answer3,answer4;
Button AnswerButtons [] = {answer1,answer2,answer3,answer4};


 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.play);

        QuestionList = new ArrayList<Question>();
        ArrayList <String> answer = new ArrayList<String>();

        answer.add("8");
        answer.add("9");
        answer.add("3");
        answer.add("1");
        QuestionList.add(new Question("what is 4+4", answer, 0));
        answer.add("17");
        answer.add("20");
        answer.add("15");
        answer.add("14");
        QuestionList.add(new Question("what is 7+8?", answer, 3));
        answer.add("20");
        answer.add("30");
        answer.add("19");
        answer.add("34");
        QuestionList.add(new Question("what is 10+10?", answer, 0));
        answer.add("12");
        answer.add("11");
        answer.add("13");
        answer.add("14");
        QuestionList.add(new Question("what is 6+6?", answer, 0));
        answer.add("6");
        answer.add("5");
        answer.add("4");
        answer.add("7");
        QuestionList.add(new Question("what is 4+3?", answer, 3));
        answer.add("7");
        answer.add("9");
        answer.add("10");
        answer.add("11");
        QuestionList.add(new Question("what is 3+7?", answer, 2));


        questionstextview = (TextView) findViewById (R.id.questionstextview);

        questionnumber = (TextView) findViewById (R.id.questionnumber);


        View AnswerButton1 = findViewById(R.id.answerbutton1);
        AnswerButton1.setOnClickListener(this);
        View AnswerButton2 = findViewById(R.id.answerbutton2);
        AnswerButton2.setOnClickListener(this);
        View AnswerButton3 = findViewById(R.id.answerbutton3);
        AnswerButton3.setOnClickListener(this);
        View AnswerButton4 = findViewById(R.id.answerbutton4);
        AnswerButton4.setOnClickListener(this);

    }


private void ButtonPress (Button answerButton){



}

public play() {

}


@Override
public void onClick(View v) {


}

Answer 1

使用单选按钮选择正确答案，然后使用按钮继续下一个问题。！

优势

1. 从一个活动到另一个活动将更加真实（就像翻页一样）
2. 给人一种升一级的感觉！！ ;)
3. 最重要的是更容易实现（我觉得那样更容易）

活动布局的xml代码：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.stackoverflow.MainActivity" >

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world" />
<RadioGroup
android:id="@+id/rad_btn_group1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="onRadioButtonClicked" >
<RadioButton
    android:id="@+id/radioButton4"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="16dp"
    android:text="@string/radio_button1" />

<RadioButton
    android:id="@+id/radioButton1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="21dp"
    android:text="@string/radio_button2" />

<RadioButton
    android:id="@+id/radioButton2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="21dp"
    android:text="@string/radio_button3" />

<RadioButton
    android:id="@+id/radioButton3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/radio_button4"
    android:layout_marginTop="21dp" />

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="21dp"
    android:text="@string/btn_submit" />

</RadioGroup>

</RelativeLayout>

游戏逻辑的java代码如下：

public class MainActivity extends Activity implements OnClickListener{


Button btn ;
RadioGroup selectionGroup;
public static int score = 0;//to access it in other class as well to ++ or --
boolean answerAttempt = false; //to penalize player changing the answer      ;)

@Override
protected void onCreate(Bundle savedInstanceState)  {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    btn = (Button) findViewById(R.id.button1);
    btn.setOnClickListener(this);
    selectionGroup = (RadioGroup) findViewById(R.id.rad_btn_group1);
    selectionGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            // TODO Auto-generated method stub
            //because we know radiobutton3 is contains the right answer :)
            if(answerAttempt)
            {
                score -= 2;
            }
            else if (R.id.radioButton3 == checkedId && !answerAttempt)
            {
                ++score;
                answerAttempt = true; //meaning first attempt is made by the player
            }
            else
            {
                --score;
                answerAttempt = true; //meaning first attempt is made by the player
            }

        }
    });
}



@Override
public void onClick(View v) {
    // TODO Auto-generated method stub


switch(v.getId())//this is the id of the button clicked (in our case submit button)
    {
    case R.id.button1://this is the id of the submit button in xml
        //start another activity from here for next question on another activity :)

        break;
    }

}
}
