android-viewpager

问题 I'm writing my first fragment-based app and running into some heavy problems which i couldn't solve with the API or Stackoverflow. I am using a viewPager to swipe between two lists.

The problem is: FragmentList A returns the debug message for FragmentList B FragmentList B returns no debug message ... // The main class public class

问题 I'm using Glide to load image into a ViewPager using an PagerAdapter . When I load the images using the following method: Glide.with(mContext).load(mImage).placeholder(R.drawable.placeholder).into(mImageView); Everything works fine, but now I need to get the bitmap from glide and store it in a map when it loads for future edit, so I switched this method to the following one: Glide.with(mContext).load(mImage).asBitmap().placeholder(R.drawable.placeholder).into(new SimpleTarget<Bitmap>() {

问题 I would like to use fragments (not support fragments) with a view pager, I understand the v13 library has support for fragments but I don't want to import the whole library for my project.

It can be found in the android-support-v4 and android-support-v13 libraries. android-support-v13 is a superset of android-support-v4 , adding in some

问题 I am using a viewpager "tabs + swipe" and I would like to set different titles in the actionBar for each fragment so that when I switch, title changes. I tried several things without success, only the last title displays... and does not change anymore when I switch... 回答1: First, make your activity implement an OnPageChangeListener. Then, when you create your ViewPager , you can use mViewPager.setOnPageChangeListener(this) so that your activity will receive callbacks when the page changes.
