目标

每 X 秒需要更新作业和可能的答案。

试图

可能的答案已使用ll.addView(radioGroupPossibleAnswers(params3));.

这个想法是，在更新线程中调用radioGroupPossibleAnswers(params3);将更新无线电组中的可能答案，就像这样通过调用textView2.setText("" + assignment.getAssignment() + "");.

更新线程

assignment.setRandomIntegerOneAndTwo(10);

assignmentTextView.setText("" + assignment.getAssignment() + "");

RelativeLayout relativeLayout = new RelativeLayout(this);

relativeLayout.addView(assignmentTextView);
relativeLayout.addView(radioGroupPossibleAnswers(radioGroupLayoutParams));

setContentView(relativeLayout);

Thread t = new Thread() {
    @Override
    public void run() {
        try {
            while (!isInterrupted()) {
                Thread.sleep(10000);
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        tenSecondCountDown(countDownTextView);
                        assignment.setRandomIntegerOneAndTwo(10);

                        assignmentTextView.setText(""
                                + assignment.getAssignment() + "");

                        RelativeLayout.LayoutParams params3 = new RelativeLayout.LayoutParams(
                                LayoutParams.WRAP_CONTENT,
                                LayoutParams.WRAP_CONTENT);

                        radioGroupPossibleAnswers(params3);
                    }
                });
            }
        } catch (InterruptedException e) {
        }
    }
};
t.start();

无线电集团

private RadioGroup radioGroupPossibleAnswers(
        android.widget.RelativeLayout.LayoutParams p) {
    RadioGroup rg = new RadioGroup(this);
    rg.setOrientation(RadioGroup.VERTICAL);
    rg.setLayoutParams(p);
    ArrayList<Integer> a = assignment.getPossibleAnswers();
    final RadioButton[] rb = new RadioButton[5];
    for (int i = 0; i < assignment.getPossibleAnswers().size(); i++) {
        int possibleAnswer = a.get(i);

        System.out.println("Possible answer: " + a.get(i));

        rb[i] = new RadioButton(this);
        rb[i].setText(a + " " + assignment.getPossibleAnswers().size()
                + " " + i + " " + possibleAnswer);
        rb[i].setId(i);
        rb[i].setTextSize(30);

        rg.addView(rb[i]);
    }
    return rg;
}

结果

尽管分配更新并且radioGroupPossibleAnswers每 10 秒调用一次（图 1）并且可能的答案会更新（图 2），但可能的答案保持不变。

图1

图 1：每radioGroupPossibleAnswers十秒调用一次

图 2

图 2：可能的答案每十秒更新一次
