  1. POAndroid: Text Colors not changing
    text
    copied!<p>I'm writing a quiz application which presents the user with a question and 4 choices. When the user clicks on a choice, the app should change the colour of the correct choice to green and the colour of the incorrect choice to red. It should then wait a second before displaying the next question.</p> <p>The problem is that it doesn't do the colour changes (except for the last question) and I don't understand why. I know that my <code>android.os.SystemClock.sleep(1000)</code> has something to do with it. </p> <p>I'd appreciate it if you could tell me where I've gone wrong or if I'm going about this an incorrect way. Thanks :)</p> <pre><code>public void onClick(View v) { setButtonsEnabled(false); int answer = Integer.parseInt(v.getTag().toString()); int correct = question.getCorrectAnswer(); if(answer == correct) numCorrect++; highlightAnswer(answer,correct,false); android.os.SystemClock.sleep(1000); MCQuestion next = getRandomQuestion(); if(next != null) { question = next; highlightAnswer(answer,correct,true); displayQuestion(); setButtonsEnabled(true); } else { float percentage = 100*(numCorrect/questionsList.size()); QuizTimeApplication.setScore(percentage); Intent scoreIntent = new Intent(QuestionActivity.this,ScoreActivity.class); startActivity(scoreIntent); } } private void setButtonsEnabled(boolean enable) { for(Button b: buttons) b.setEnabled(enable); } private void highlightAnswer(int answer, int correct, boolean undo) { if(undo) { for(Button button : buttons) { button.setTextColor(getResources().getColor(R.color.white)); button.setTextSize(FONT_SIZE_NORMAL); } return; } buttons[correct].setTextColor(getResources().getColor(R.color.green)); buttons[correct].setTextSize(FONT_SIZE_BIG); if(answer!=correct) { buttons[answer].setTextColor(getResources().getColor(R.color.red)); buttons[answer].setTextSize(FONT_SIZE_BIG); } } </code></pre>
