帶有3個按鈕的Android小部件。 和不同的意圖

Question

我試圖創建一個Widget有一個奇怪的問題。 小部件是一個隨機問題，有3個答案選項（按鈕）。 我從互聯網加載問題，這是有效的。

我混淆了答案，所以答案並不總是在同一個地方。 此外，可以有多個正確的答案。

public RemoteViews setAnswers(JSONObject questionObj, RemoteViews views) throws JSONException {
    // Get the Answers
    String answerA = questionObj.getString("Ans1");
    String answerB = questionObj.getString("Ans2");
    String answerC = questionObj.getString("Ans3");

    // Get the Answers that is correct (1 = Correct, 0 = Wrong)
    int correctA = Integer.parseInt(questionObj.getString("correct1"));
    int correctB = Integer.parseInt(questionObj.getString("correct2"));
    int correctC = Integer.parseInt(questionObj.getString("correct3"));

    // Get help text for correct or wrong answer (HTML)
    String HTTPcor = questionObj.getString("HTTPcor")+" - Correct";
    String HTTPwro = questionObj.getString("HTTPwro")+" - Wrong";

    // Create the Intent for the answers that is correct
    Intent correctIntent = new Intent(maincontext, AdMain.class);
    correctIntent.putExtra("appWidID", appWidId);
    correctIntent.putExtra("correct", 1); // Answer is correct.
    correctIntent.putExtra("HTTP", HTTPcor); // Help text.
    PendingIntent correctIntentPending = PendingIntent.getActivity(maincontext, 0, correctIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    // Create the Intent for the answers that is wrong
    Intent wrongIntent = new Intent(maincontext, AdMain.class);
    wrongIntent.putExtra("appWidID", appWidId);
    wrongIntent.putExtra("correct", 0); // Answer is wrong.
    wrongIntent.putExtra("HTTP", HTTPwro); // Help text.
    PendingIntent wrongIntentPending = PendingIntent.getActivity(maincontext, 0, wrongIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    // Create a random number between 1 and 6 (6 different ways to mix up 3 buttons)
    Random generator = new Random();
    int mix = generator.nextInt(6) + 1;
    Log.v("JapanWidget", "AnswerMix - "+mix+" - appWidId = "+appWidId);

    // DEBUG Set mix to 1 Until i get the Intent fixed.
    mix = 1;

    // Mix the buttons.
    switch(mix) {
      case 1:
          views.setTextViewText(R.id.Answer1, answerA); // Button 1 answer A
          // If correctA = 1 THEN set correctIntentPending ELSE set wrongIntentPending
          if (correctA == 1) { views.setOnClickPendingIntent(R.id.Answer1, correctIntentPending); } else { views.setOnClickPendingIntent(R.id.Answer1, wrongIntentPending); }
          views.setTextViewText(R.id.Answer2, answerB); // Button 2 answer B
          // If correctB = 1 THEN set correctIntentPending ELSE set wrongIntentPending
          if (correctB == 1) { views.setOnClickPendingIntent(R.id.Answer2, correctIntentPending); } else { views.setOnClickPendingIntent(R.id.Answer2, wrongIntentPending); }
          views.setTextViewText(R.id.Answer3, answerC); // Button 3 answer C
          // If correctB = 1 THEN set correctIntentPending ELSE set wrongIntentPending
          if (correctC == 1) { views.setOnClickPendingIntent(R.id.Answer3, correctIntentPending); } else { views.setOnClickPendingIntent(R.id.Answer3, wrongIntentPending); }
          break;
      default:  
          views.setTextViewText(R.id.Answer1, answerA);
          if (correctA == 1) { views.setOnClickPendingIntent(R.id.Answer1, correctIntentPending); } else { views.setOnClickPendingIntent(R.id.Answer1, wrongIntentPending); }
          views.setTextViewText(R.id.Answer2, answerB);
          if (correctB == 1) { views.setOnClickPendingIntent(R.id.Answer2, correctIntentPending); } else { views.setOnClickPendingIntent(R.id.Answer2, wrongIntentPending); }
          views.setTextViewText(R.id.Answer3, answerC);
          if (correctC == 1) { views.setOnClickPendingIntent(R.id.Answer3, correctIntentPending); } else { views.setOnClickPendingIntent(R.id.Answer3, wrongIntentPending); }
          break;
    }

    return views;
}

問題是，當我從新的Activity中執行GetExtra時，它將始終是在wrongIntentPending中設置的額外內容。 這里出現問題。 但我確實看到“if（correctA == 1）{} else {}”的工作正確。 即使我將其設置為“if（correctA == 1）{} else {}”，然后我從wrongIntentPending獲取Extra。

出了什么問題？ 或者有更好的方法嗎？

我在閱讀本頁后發現了這個問題： http ： //www.bogdanirimia.ro/android-widget-click-event-multiple-instances/269

工作代碼：

// Create the Intent for the answers that is correct
Intent correctIntent = new Intent(maincontext, AdMain.class);
correctIntent.putExtra("appWidID", appWidId);
correctIntent.putExtra("correct", 1); // Answer is correct.
correctIntent.putExtra("HTTP", HTTPcor); // Help text.
PendingIntent correctIntentPending = PendingIntent.getActivity(maincontext, 0, correctIntent, PendingIntent.FLAG_UPDATE_CURRENT);

// Create the Intent for the answers that is wrong
Intent wrongIntent = new Intent(maincontext, AdMain.class);
wrongIntent.putExtra("appWidID", appWidId);
wrongIntent.putExtra("correct", 0); // Answer is wrong.
wrongIntent.putExtra("HTTP", HTTPwro); // Help text.
PendingIntent wrongIntentPending = PendingIntent.getActivity(maincontext, 1, wrongIntent, PendingIntent.FLAG_UPDATE_CURRENT);

在“PendingIntent getActivity（Context context，int requestCode，Intent intent，int flags）”中，我需要設置2個不同的requestCodes。 即便是谷歌開發者網頁說它目前還沒有使用過。

• context：PendingIntent應該啟動活動的Context。
• requestCode：發件人的私有請求代碼（當前未使用）。
• intent：要啟動的活動的意圖。
• flags：可以是FLAG_ONE_SHOT，FLAG_NO_CREATE，FLAG_CANCEL_CURRENT，FLAG_UPDATE_CURRENT或Intent.fillIn（）支持的任何標志，以控制實際發送時可以提供的意圖的哪些未指定部分。

所以我改變了這一行：

PendingIntent wrongIntentPending = PendingIntent.getActivity（maincontext， 1 ，wrongIntent，PendingIntent.FLAG_UPDATE_CURRENT）;

現在它有效。
