我想用 viewpager 在问题之间滑动
1) 我可以通过以下代码使用自定义页面，例如 ("text1", "text2", "text3, "text4")：在 pageadapter 中：
protected static final String[] CONTENT = new String[] { "text1", "text2", "text3, "text4", };
1）但我无法将数据从数据库获取到字符串，例如：
new String[] { "myquestion1", "myquestion2", ....... "my lastquestion", }
在我的测验活动中：
/**
*
*/
public void initView() {
this.manageView(true);
}
/**
* updates the user interface
*
* @param start whether this is the start of the quiz
*/
@SuppressWarnings("boxing")
public void manageView(final boolean start) {
if (QuizActivity.ll.getChildCount() > 0) {
QuizActivity.ll.removeAllViews();
QuizActivity.ll.addView(QuizActivity.questionText);
}
QuizActivity.warning.setVisibility(View.INVISIBLE);
QuizActivity.warningIcon.setVisibility(View.INVISIBLE);
if (this.q.isReviewing()) {
QuizActivity.warning.setVisibility(View.VISIBLE);
QuizActivity.warningIcon.setVisibility(View.VISIBLE);
if (this.q.getCurrentQuestion().isAnsweredCorrect()) {
QuizActivity.warning.setText(R.string.correct);
QuizActivity.warning.setTextColor(Statics.goodColor);

QuizActivity.warning.setText(R.string.wrong);
QuizActivity.warning.setTextColor(Statics.badColor);
QuizActivity.warningIcon.setImageResource(R.drawable.wrong);
}
}
QuizActivity.back.setEnabled((!start || this.q.isBackAllowed())
&& (!this.q.isFirstQuestion()));
if (this.q.isLastQuestion()) {
QuizActivity.next.setText(R.string.finish);
QuizActivity.next.setCompoundDrawablesWithIntrinsicBounds(null, null,

QuizActivity.next.setOnClickListener(this);

那么如何将我的问题列表应用于“ new String[] {...,...,... } ”
