我目前正在製作一本像教育目的的小型書籍，我正在使用頁面查看器將信息從我的Strings.xml放在每個頁面上。這是一本相當小的書，所以我這樣做。我顯示了所有頁面，您可以輕鬆瀏覽，而不會出現任何問題。當我只想顯示一定的頁面間隔時，我的問題就開始了。遊戲中有三個教訓。在第一課中有2頁（1-2），第二課有（3-9）和第三課（10-15）。共有15頁信息。如何通過頁面查看器顯示頁面的間隔
有沒有辦法讓頁面查看器只顯示一定的頁面間隔？
我讓用戶選擇一個按鈕，這發送了一個意向，並將其中的課程挑選給另一個名爲BookActivity的類。從那裏我得知想要弄清楚哪個課程被點擊了，並且想要基於那個顯示某些頁面。這是bookActivity類。
public class BookActivity extends Activity
{
private String getLessonName;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent intent = getIntent();
// getting object's properties from LoginActivity class.
getLessonName = intent.getStringExtra("nameOfLesson");
MyPageAdapter adapter = new MyPageAdapter();
ViewPager myPager = (ViewPager) findViewById(R.id.myfivepanelpager);
// Button addBasicQuestionsForFirstLesson = (Button)findViewById(R.id.addBasicQuestionsButton);
myPager.setAdapter(adapter);
if(getLessonName.equals("one"))
{
myPager.setCurrentItem(0);
if(myPager.getCurrentItem() == 1)
{
myPager.setCurrentItem(1);
}
}
else if(getLessonName.equals("two"))
{
myPager.setCurrentItem(2);
if(myPager.getCurrentItem() == 8)
{
myPager.setCurrentItem(8);
}
}
else if(getLessonName.equals("three"))
{
myPager.setCurrentItem(9);
if(myPager.getCurrentItem()==14)
{
myPager.setCurrentItem(14);
}
}
}
}
非常感謝您爲我着想。如果有人知道如何做這樣的事情，我會非常感激。我並不想爲單獨的頁面多項活動，如果這是有辦法做到這一點更好....

再次感謝您。這是我添加的代碼！
我認爲你必須根據你的要求設置適配器，假設如果用戶先選擇課程，然後適配器將只配置兩個頁面數據，並再次設置myPager.setAdapter（適配器）; ，如果用戶選擇第二課，則適配器將使用3-9頁數據進行配置，並再次設置myPager.setAdapter（適配器）;. – rajpara 2012-08-09 14:42:14
聽起來很合理。好吧，我會試試這個並報告回來。 – Tastybrownies 2012-08-09 15:16:24
好吧，我試圖做到這一點，並對使用什麼方法感到困惑。我沒有太多的頁面查看器的經驗。到目前爲止，如果我有：myPager.setCurrentItem（2）;爲什麼沒有setEndingItem？ :) – Tastybrownies 2012-08-09 15:39:17
