Hello Folks! Welcome to Our Blog.

If you use the android Gmail application, you probably noticed that the progress bar is a bit customized. I am not talking about the pull to resfresh but the indeterminate progress bar which appears just after. This indeterminate drawable is much smoother than the usual. I will show you in this post a way to reproduce this smooth indeterminate horizontal progress bar. Here is the result: the first progress bar uses the default indeterminate drawable while the others are all custom.

There is apparently a problem with the size of the video, so you might want to click on this link to see it on Youtube. First of all, you will need to use the Horizontal progress bar style: Widget. Horizontal for pre ICS and Widget. Horizontal for post ICS devices. We just have to make a custom indeterminate drawable which dynamically draws lines instead of drawing bitmaps. Basically we have some kind of exponential function we use to compute the length of each part of the drawable.

In fact, the code is even simpler than that.

We just have to loop and draw lines bigger than the previous one. You also have to take the offset in account, as this value will let you to have an animation. I used the expm1 function which returns exp x - 1 but you can try any growing function. We could imagine a function which multiply by two the previous part each time, or some kind of fibonacci sequence.

I could stop here but I wanted to go further and give to our drawable the possibility to be fully customizable. It allows developers to radically change their animation in just one line. You can make it bounce, overshoot,… just by changing the interpolator.

I used interpolators here to change the way the animation looks like. Basically, we set a number of sections. The animation is done by an offset, incremented at each frame.

So far so good. What I want to do is to animate the progress update, so that it does not just "jump" to the value but smoothly moves to it. The problem is that the progress bar does not update its state until it finished its final value progress variable. All states in between are not displayed on the screen. Calling progressBar. Note: if from and to value are too low to produce smooth animation just multiply them by a or so.

If you do so, don't forget to multiply setMax. The simplest wayusing ObjectAnimator :. You can also change the way how values are changing by setting different interpolator with setInterpolator method. Here is an improved version of Eli Konky solution:. Currently you tell the progress bar "update to 1, update to 2, update to 3" without ever releasing the UI-thread so it actually can update. The best way to solve this problem is to use Asynctaskit has native methods that runs both on and off the UI thread:.

AsyncTask might seem complicated at first, but it is really efficient for many different tasks, or as specified in the Android API:.

Here is an improved version of a. Sometimes it's required to set constant progress and change only rotation or even both progress and rotation. It is also possible to force clockwise or counter clockwise rotation. I hope it will help. My solution with custom ProgressBar.

You can specify animation animationLength legth and "smoothness" animationSmoothness using attributes when you use it in XML layout. I just wanted to add an extra value for those who want to use Data Binding with a progress bar animation.

Right now, I have AsyncTask whic is sperated from fragments classes, and I use that AsyncTask to load data, and right now I have implement progressBar dialog, but I want to get rid of that, because I want make a better UX.

Dude, If you really just want a progress bar like the picture you posted, you can simply set the progress bar indeterminate property to true : You can eighter do on code or directly on the xml. In code: yourProgressBar. Hm, I stil get visible ProgressBar dialog, instead of showing progressBar in background as on the picture above. Did you also tried changing the visibility attribute? Every view has this attribute I use pb.

So, I didn't get your problem. Why don't you just stop using the progress dialog and start using a progress bar. You could do the same thing you're doing now.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Have you any idea how to make a circular progress bar like the one of Google Fit application? Like the image below. You can try this Circle Progress library.

In your layout include the following ProgressBar with a specific drawable note you should get the width from dimensions instead. The max value is important here:. Now create the drawable in your resources with the following shape. Play with the radius you can use innerRadius instead of innerRadiusRatio and thickness values. Next in your code use an ObjectAnimator to animate the progress field of the ProgessBar of your layout.

I'm trying to implement a smooth animation for my ProgressBarbut when I increase the time 30 secondsthe animation is no longer smooth. Because you are using ofInt you can only move at full integers. In other words, if you have a progress bar with a width of and a progress of 0 to since you are moving at an integer pace you count 1, 2, 3, 4 which translates to 10px, 20px, 30px and 40px.

Which explains the jaggedness you are seeing. To correct this you have a few options. The first is to up your integers from 0 to someBigInt This will give the animator more numbers to work with.

The other option is to use ofFloat which does the same thing as ofInt but uses floating points instead of integers. If you change progress value each time by 1 for example from 45 to 46 you won't see the animation.

You'd better change progress by points or maybe otherfor this you just need to multiply your max value by and each progress value to too. For example:.

You can not use the ofFloat because the ProgressBar's progress attribute doesn't accept float values, only integer ones. That is why your ProgressBar stopped progressing after going with that solution.

As the others have said it, the correct way to do what you want is to set android:max to some big integer. Sets the current progress to the specified value, optionally animating the visual position between the current and target values.

Animation does not affect the result of getProgresswhich will return the target value immediately after this method is called. Use the library may its help you give the time in which you want to fill the progress bar its very smooth with no lag but you little bit customize to use this.
