嗨,我正在嘗試為
Android建立一個應用程式,為了開發它,我需要浏覽不同的頁面和問題.對于這個任務,我已經定義了一個帶有一些radiobutton的radiogroup.我想要獲得的是每個問題都回答了radiobutton,當使用者進入不同的頁面時,可以檢索到該值.我已經嘗試過這個代碼,如果有一個標明的單選按鈕,則沒有建立新的單選按鈕(radiobuttons選中false).但是,使用此代碼時,始終會有一個標明的答案,是以始終選擇相同的單選按鈕.我會感激一些幫助.
radBotA.setOnCheckedChangeListener(radioCheckChangeListener);
radBotB.setOnCheckedChangeListener(radioCheckChangeListener);
radBotC.setOnCheckedChangeListener(radioCheckChangeListener);
radBotD.setOnCheckedChangeListener(radioCheckChangeListener);
radBotA.setOnClickListener(radioClickListener);
radBotB.setOnClickListener(radioClickListener);
radBotC.setOnClickListener(radioClickListener);
radBotD.setOnClickListener(radioClickListener);
if (radBotA.isChecked()){
Answers[position]="A";
}
else if(radBotB.isChecked()){
Answers[position]="B"; }
else if(radBotB.isChecked()){
Answers[position]="C"; }
else if(radBotC.isChecked()){
Answers[position]="D"; }
else if(radBotD.isChecked()){
Answers[position]="D"; }
else {
radBotA.setChecked(false);
radBotA.setChecked(false);
radBotA.setChecked(false);
radBotA.setChecked(false);
}
bPrevious.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
position = position -1;
questions.Previous();
currentQuestion();
}
});
bNext.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
position = position +1;
questions.Next();
currentQuestion();
}
});
private void currentQuestion() {
if (position==0){
bPrevious.setVisibility(View.GONE);
}else{
bPrevious.setVisibility(View.VISIBLE);
}
if (position==nPreguntas-1){
bNext.setVisibility(View.GONE);
}else{
bNext.setVisibility(View.VISIBLE);
}
questions.currentQuestion(this, category);
enunciado.setImageResource(Enunciado[position]);
pregunta.setText(questions.getPregunta());
final RadioButton radBotA = new RadioButton(this);
final RadioButton radBotB = new RadioButton(this);
final RadioButton radBotC = new RadioButton(this);
final RadioButton radBotD = new RadioButton(this);
radBotA.setText("A. " + questions.getRespuestaA());
radBotB.setText("B. " + questions.getRespuestaB());
radBotC.setText("C. " + questions.getRespuestaC());
radBotD.setText("D. " + questions.getRespuestaD());
String nprueba = "Item " + questions.getId() + " de "+ nPreguntas;
NombrePrueba.setText(nprueba);
if (radBotA.isChecked()){
Answers[position]="A";
}
else if(radBotB.isChecked()){
Answers[position]="B"; }
else if(radBotB.isChecked()){
Answers[position]="C"; }
else if(radBotC.isChecked()){
Answers[position]="D"; }
else if(radBotD.isChecked()){
Answers[position]="D"; }
else {
radBotA.setChecked(false);
radBotA.setChecked(false);
radBotA.setChecked(false);
radBotA.setChecked(false);
}
}
謝謝大家的時間
編輯：
public void save(){
SharedPreferences settings = getSharedPreferences("Answers", 0);
SharedPreferences.Editor e = settings.edit();
e.putBoolean("A0",radBotA.isChecked());
e.putBoolean("B0",radBotB.isChecked());
e.putBoolean("C0",radBotC.isChecked());
e.putBoolean("D0",radBotD.isChecked());
e.putBoolean("A1",radBotA.isChecked());
e.putBoolean("B1",radBotB.isChecked());
e.putBoolean("C1",radBotC.isChecked());
e.putBoolean("D1",radBotD.isChecked());
e.putBoolean("A2",radBotA.isChecked());
e.putBoolean("B2",radBotB.isChecked());
e.putBoolean("C2",radBotC.isChecked());
e.putBoolean("D2",radBotD.isChecked());
e.putBoolean("A3",radBotA.isChecked());
e.putBoolean("B3",radBotB.isChecked());
e.putBoolean("C3",radBotC.isChecked());
e.putBoolean("D3",radBotD.isChecked());
public void load(){
SharedPreferences settings = getSharedPreferences("Answers", 0);
boolean answerA0 = settings.getBoolean("A0", false);
boolean answerB0 = settings.getBoolean("B0", false);
boolean answerC0 = settings.getBoolean("C0", false);
boolean answerD0 = settings.getBoolean("D0", false);
boolean answerA1 = settings.getBoolean("A1", false);
boolean answerB1 = settings.getBoolean("B1", false);
boolean answerC1 = settings.getBoolean("C1", false);
boolean answerD1 = settings.getBoolean("D1", false);
boolean answerA2 = settings.getBoolean("A2", false);
boolean answerB2 = settings.getBoolean("B2", false);
boolean answerC2 = settings.getBoolean("C2", false);
boolean answerD2 = settings.getBoolean("D2", false);
boolean answerA3 = settings.getBoolean("A3", false);
boolean answerB3 = settings.getBoolean("B3", false);
boolean answerC3 = settings.getBoolean("C3", false);
boolean answerD3 = settings.getBoolean("D3", false);
但是我不知道如何繼續.我v’考慮以下代碼,但它給了我錯誤,其中posicion是“頁碼”：
public void Test(){
switch(posicion){
case(0):
if(answerA0==true){
e.putBoolean("A0",radBotA.isChecked());
}
}
}
}
