How to calculate score using Radio buttons in Android?

问题

以下是你提供的代码的翻译部分：

这是 Activity 类：

  1. public class CoughTest extends AppCompatActivity {
  3.     int score = 0;
  4.     RadioGroup rg1, rg2, rg3, rg4, rg5;
  5.     RadioButton rb;
  7.     @Override
  8.     protected void onCreate(Bundle savedInstanceState) {
  9.         super.onCreate(savedInstanceState);
  10.         setContentView(R.layout.activity_cough_test);
  12.         rg1 = (RadioGroup) findViewById(R.id.rgroup1);
  13.         rg2 = (RadioGroup) findViewById(R.id.rgroup2);
  14.         rg3 = (RadioGroup) findViewById(R.id.rgroup3);
  15.         rg4 = (RadioGroup) findViewById(R.id.rgroup4);
  16.         rg5 = (RadioGroup) findViewById(R.id.rgroup5);
  17.     }
  19.     public void rbClicked(View view) {
  20.         int radioButtonId = rg1.getCheckedRadioButtonId();
  21.         rb = (RadioButton) findViewById(radioButtonId);
  23.         boolean checked = ((RadioButton) view).isChecked();
  25.         switch (view.getId()){
  26.             case R.id.yes1:
  27.                 score = score + 20;
  28.                 break;
  29.             case R.id.no1:
  30.                 score = 0;
  31.                 break;
  32.             case R.id.yes2:
  33.                 score = score + 20;
  34.                 break;
  35.             case R.id.no2:
  36.                 score = 0;
  37.                 break;
  38.             case R.id.yes3:
  39.                 score = score + 20;
  40.                 break;
  41.             case R.id.no3:
  42.                 score = 0;
  43.                 break;
  44.             case R.id.yes4:
  45.                 score = score + 20;
  46.                 break;
  47.             case R.id.no4:
  48.                 score = 0;
  49.                 break;
  50.             case R.id.yes5:
  51.                 score = score + 20;
  52.                 break;
  53.             case R.id.no5:
  54.                 score = 0;
  55.                 break;
  56.         }
  57.     }
  58. }

英文:

I have been developing a form which uses Radio buttons and has a list of questions.

When the user clicks on Yes radio button for every question, I want to increment the score by 20. If the user clicks the No radio button, the score should be 0.

Take a look at the code.

This is the Activity class

CoughTest.java

  1.   public class CoughTest extends AppCompatActivity {
  2. int score= 0;
  3. RadioGroup rg1,rg2,rg3,rg4,rg5;
  4. RadioButton rb;
  5. @Override
  6. protected void onCreate(Bundle savedInstanceState) {
  7. super.onCreate(savedInstanceState);
  8. setContentView(R.layout.activity_cough_test);
  9. rg1 = (RadioGroup) findViewById(R.id.rgroup1);
  10. rg2 = (RadioGroup) findViewById(R.id.rgroup2);
  11. rg3 = (RadioGroup) findViewById(R.id.rgroup3);
  12. rg4 = (RadioGroup) findViewById(R.id.rgroup4);
  13. rg5 = (RadioGroup) findViewById(R.id.rgroup5);
  14. }
  15. public void rbClicked(View view) {
  16. int radioButtonId = rg1.getCheckedRadioButtonId();
  17. rb =(RadioButton) findViewById(radioButtonId);
  18. boolean checked = ((RadioButton) view).isChecked();
  19. switch (view.getId()){
  20. case R.id.yes1:
  21. score = score + 20;
  22. break;
  23. case R.id.no1:
  24. score = 0;
  25. break;
  26. case R.id.yes2:
  27. score = score + 20;
  28. break;
  29. case R.id.no2:
  30. score = 0;
  31. break;
  32. case R.id.yes3:
  33. score = score + 20;
  34. break;
  35. case R.id.no3:
  36. score = 0;
  37. break;
  38. case R.id.yes4:
  39. score = score + 20;
  40. break;
  41. case R.id.no4:
  42. score = 0;
  43. break;
  44. case R.id.yes5:
  45. score = score + 20;
  46. break;
  47. case R.id.no5:
  48. score = 0;
  49. break;
  50. }
  51. }
  52. }

答案1

得分: 1

我将建议这种方法：

CoughTest.java：

  1. public class CoughTest extends AppCompatActivity {
  3.     private Button btnSubmit, btnReset;
  4.     private TextView finalScore;
  5.     private RadioButton cough, sourThroat, fever, tiredness, breathing;
  7.     private int score = 0;
  9.     @Override
  10.     protected void onCreate(Bundle savedInstanceState) {
  11.         super.onCreate(savedInstanceState);
  12.         setContentView(R.layout.activity_cough_test);
  14.         btnSubmit = (Button) findViewById(R.id.btnSubmit);
  15.         btnReset = (Button) findViewById(R.id.btnReset);
  16.         finalScore = (TextView) findViewById(R.id.textFinalScore);
  18.         cough = (RadioButton) findViewById(R.id.cough);
  19.         sourThroat = (RadioButton) findViewById(R.id.sour_throat);
  20.         fever = (RadioButton) findViewById(R.id.fever);
  21.         tiredness = (RadioButton) findViewById(R.id.tiredness);
  22.         breathing = (RadioButton) findViewById(R.id.breathingDifficulty);
  24.         btnSubmit.setOnClickListener(new View.OnClickListener() {
  25.             @Override
  26.             public void onClick(View v) {
  27.                 if (cough.isChecked()) {
  28.                     score = score + 20;
  29.                 } else {
  30.                     score = score + 0;
  31.                 }
  33.                 if (sourThroat.isChecked()) {
  34.                     score = score + 20;
  35.                 } else {
  36.                     score = score + 0;
  37.                 }
  39.                 if (fever.isChecked()) {
  40.                     score = score + 20;
  41.                 } else {
  42.                     score = score + 0;
  43.                 }
  45.                 if (tiredness.isChecked()) {
  46.                     score = score + 20;
  47.                 } else {
  48.                     score = score + 0;
  49.                 }
  51.                 if (breathing.isChecked()) {
  52.                     score = score + 20;
  53.                 } else {
  54.                     score = score + 0;
  55.                 }
  57.                 // 最后显示您的得分。
  58.                 Toast.makeText(getApplicationContext(), "得分是：" + score, Toast.LENGTH_SHORT).show();
  60.             }
  61.         });
  62.         // 重置所有内容
  63.         btnReset.setOnClickListener(new View.OnClickListener() {
  64.             @Override
  65.             public void onClick(View v) {
  66.                 score = 0;
  67.                 cough.setChecked(false);
  68.                 fever.setChecked(false);
  69.                 breathing.setChecked(false);
  70.                 tiredness.setChecked(false);
  71.                 sourThroat.setChecked(false);
  72.             }
  73.         });

我已删除了单选按钮组。只需提示用户在同意时单击它。这意味着如果他们的答案是“是”，请勾选单选按钮，否则保持未选中。希望这有所帮助。

顺便说一下，它的工作原理如下：如何在Android中使用单选按钮计算分数？

英文:

I will suggest this method:

CoughTest.java:

  1. public class CoughTest extends AppCompatActivity {
  2. private Button btnSubmit, btnReset;
  3. private TextView finalScore;
  4. private RadioButton cough, sourThroat, fever, tiredness, breathing;
  5. private  int score = 0;
  6. @Override
  7. protected void onCreate(Bundle savedInstanceState) {
  8. super.onCreate(savedInstanceState);
  9. setContentView(R.layout.activity_cough_test);
  10. btnSubmit = (Button) findViewById(R.id.btnSubmit);
  11. btnReset = (Button) findViewById(R.id.btnReset);
  12. finalScore = (TextView) findViewById(R.id.textFinalScore);
  13. cough = (RadioButton) findViewById(R.id.cough);
  14. sourThroat = (RadioButton) findViewById(R.id.sour_throat);
  15. fever = (RadioButton) findViewById(R.id.fever);
  16. tiredness = (RadioButton) findViewById(R.id.tiredness);
  17. breathing = (RadioButton) findViewById(R.id.breathingDifficulty);
  18. btnSubmit.setOnClickListener(new View.OnClickListener() {
  19. @Override
  20. public void onClick(View v) {
  21. if (cough.isChecked()) {
  22. score = score + 20;
  23. } else {
  24. score = score + 0;
  25. }
  26. if (sourThroat.isChecked()) {
  27. score = score + 20;
  28. } else {
  29. score = score + 0;
  30. }
  31. if (fever.isChecked()) {
  32. score = score + 20;
  33. } else {
  34. score = score + 0;
  35. }
  36. if (tiredness.isChecked()) {
  37. score = score + 20;
  38. } else {
  39. score = score + 0;
  40. }
  41. if (breathing.isChecked()) {
  42. score = score + 20;
  43. } else {
  44. score = score + 0;
  45. }
  46. //Finally show your score.
  47. Toast.makeText(getApplicationContext(), &quot;Score is: &quot; + score, Toast.LENGTH_SHORT).show();
  48. }
  49. });
  50. //Resetting everything
  51. btnReset.setOnClickListener(new View.OnClickListener() {
  52. @Override
  53. public void onClick(View v) {
  54. score = 0;
  55. cough.setChecked(false);
  56. fever.setChecked(false);
  57. breathing.setChecked(false);
  58. tiredness.setChecked(false);
  59. sourThroat.setChecked(false);
  60. }
  61. });
  62. }

}

  80. &lt;Button
  81. android:layout_width=&quot;wrap_content&quot;
  82. android:layout_height=&quot;wrap_content&quot;
  83. android:text=&quot;Reset&quot;
  84. android:layout_marginTop=&quot;5sp&quot;
  85. android:id=&quot;@+id/btnReset&quot;
  86. android:layout_marginStart=&quot;50sp&quot;/&gt;
  87. &lt;TextView
  88. android:layout_width=&quot;wrap_content&quot;
  89. android:layout_height=&quot;wrap_content&quot;
  90. android:layout_marginTop=&quot;20sp&quot;

  92. android:hint=&quot;Your Score Here&quot;
  93. android:textColor=&quot;#000000&quot;

  95. &lt;/LinearLayout&gt;
  96. &lt;/ScrollView&gt;
  97. &lt;/RelativeLayout&gt;

I have removed the radio groups. Just prompt your user to click it when they agree.
Means if their answer is YES, then please check the radio button else leave it unchecked.
Hope that helps.

By the way this is how it works:
如何在Android中使用单选按钮计算分数？

答案2

得分: 0

只需在您的switch case之后将分数设置到您的textView中：

  1. yourTextView.setText(String.valueOf(score));
英文:

just set score into your textView after your switch case :

  1. yourTextView = String.ValueOf(score);
