1 | # HeartProgressBar
2 |
3 |
4 |
5 | I've wrote this progress bar for my girlfriend. It's sound strange, I know it :)
6 | But feel free to use it in your Android apps.
7 | *HeratProgressBar* - just progress bar looks like heart with nice animation.
8 |
9 | ## Demo
10 |
11 | It's demo app with [HeartProgressBar](https://www.dropbox.com/s/1287va7jiqs3kgh/app-debug.apk).
12 |
13 |
14 | ## How to Use it
15 |
16 | Just follow all steps below and enjoy this custom view.
17 |
18 | ### Step 1:
19 |
20 | Copy **HeartProgressBar.java** in your project.
21 |
22 | ### Step 2:
23 |
24 | Add **HeartProgressBar** in your XML layour like in example below
25 |
26 |
30 |
31 |
32 | `Note: width and height of HeartProgressBar should be equals.`
33 |
34 | ### Step 3:
35 |
36 | Find HeartProgressBar in your layout and start/dismiss it.
37 |
38 | HeartProgressBar progressBar = (HeartProgressBar) findViewById(R.id.progressBar);
39 |
40 | progressBar.start();
41 |
42 | progressBar.dismiss();
43 |
44 |
45 | ## In future...
46 |
47 | I'll make this .jar library.
48 |
49 | Add animation drawing proccess to separate thread for better performance.
