Calculates the vertical scroll amount necessary to make the given view fully visible inside the RecyclerView.

When scrolling towards a child view, this method defines whether we should align the left or the right edge of the child with the parent RecyclerView. When scrolling towards a child view, this method defines whether we should align the top or the bottom edge of the child with the parent RecyclerView.

Is there a way to adjust the scrolling on android, Nexus 7 OG to be specific.

Its just not smooth. Hard to explain, but im used to the iphone 5 scrolling which is smooth as butter. Anyone that goes back and forth between ios and android should know what im talking about.

Jul 22, 3, 9 AustinInDallas said:. NikolaeVarius Lifer.In its early days, Android was a slow and buggy mobile platform. Even the most powerful smartphones that were released each year would experience stuttering and stammering while performing the simplest of tasks, like scrolling or opening apps. And if your Android flagship phone was actually doing some heavy lifting like playing a resource-intensive game, it was a total mess.

Modern Android flagship phones — and even some mid-range Android phones — are much smoother than they were even as recently as a few years ago. Top flagships are still powerhouses, and now the Android operating system no longer holds them back. Optimizations made by Google within Android are partially to thank, but manufacturers have fine-tuned their own software as well. Why is the iPhone so darn smooth? There are a few main reasons.

The transition animations that take place as you open, close, and switch apps in iOS are faster and smoother than their counterparts in Android.

Stop for a moment and think about what you actually do when you use your phone. Every time you do any of that, a transition animation is displayed, and the speed of that animation indeed has a big impact on your perception of smoothness and speed.

On Apple devices, those animations are lightning-fast and very smooth. Of course, Android is far more flexible than iOS in so many ways, and the ability to adjust the speed of those animations is among them. This is an awesome, important feature that has a profound impact on the overall user experience, and we want as many people as possible to be aware of it. Do you want to try it out? To speed up your transition animations, tap Developer options and scroll down until you see the following items note that you may need to open the Advanced settings depending on which phone you have :.

Some stickier scroll wheels take all the strength you have to get down a notch or two, while others can be too loose and will have you hugging the bottom of the page with a light flick.

You can do this by either clicking on the scale and tapping left or right on your arrow keys, or holding the indicator down and dragging it to the number you want. Once the mouse dialog pops up, you should see a window that looks something like this. Every time you scroll a notch, the wheel will skip an entire page of content at once, rather than going through it line by line. Which scroll speed is right for you will be based on your mouse and your own personal preference.

Keep in mind that your mouse may also have its own additional sensitivity settings, either on the mouse itself or in the software that came with it.

Of all the great advantages RecyclerView has over ListView, one feature that I miss a lot is fast scrolling where you could drag a thumb drawable and scroll around the list.

In ListView you could do the following :. But with RecyclerView, there is no easy way to have a thumb drawable like so :. So we would rely on libraries like this and this.

It works fine without reflection and is very flexible. Also there is no need for making custom ViewPager and putting it into android.

Here is an example:. As you can see in ViewPager sources, duration of fling controlled by mScroller object. In documantation we may read:. The duration of the scroll can be passed in the constructor and specifies the maximum time that the scrolling animation should take. It calculates the duration based on a few things. See anything we can control? OnPageChangeListener in our adapter. The following is Kotlin impl of this part of the adapter which turns the duration into If you have to support settling after a drag, then you need to do a bit more in your calculation.

One downside is that this depends on that hardcoded base duration value in ViewPager. If that changes, then your durations change with this approach.

I wanted to solve the same issue as all of you and this is my solution for the same problem, but I think this way the solution is more flexible as you can change the duration however you like and also change the interpolation of the values as desired to achieve different visual effects.

I think this is the most flexible solution for performing this task.
