pager.setOnPageChangeListener(new MyPageChangeListener()); 
private int indexOfImage = 0; 
private class MyPageChangeListener extends ViewPager.SimpleOnPageChangeListener { 
    @Override 
    public void onPageSelected(int position) { 
     indexOfImage = position; 
    } 
}

设置为墙纸

int id=ListOfID[indexOfImage]; 
WallpaperManager myWallpaperManager 
    = WallpaperManager.getInstance(getApplicationContext()); 
myWallpaperManager.setResource(id);

我改变app.class（第一消息），但ID不会改变（总是相同的图片）问题出在哪里？ –
