138 | 6. Trademarks. This License does not grant permission to use the trade

162 | other commercial damages or losses), even if such Contributor
163 | has been advised of the possibility of such damages.

168 | or other liability obligations and/or rights consistent with this
169 | License. However, in accepting such obligations, You may act only
170 | on Your own behalf and on Your sole responsibility, not on behalf
171 | of any other Contributor, and only if You agree to indemnify,
172 | defend, and hold each Contributor harmless for any liability
173 | incurred by, or claims asserted against, such Contributor by reason
174 | of your accepting any such warranty or additional liability.

1 | # ExpandableCardView
2 |
3 | [  ](https://bintray.com/alespero/ExpandableCardView/ExpandableCardView/0.8/link)
4 |
5 | 
6 |
7 | An Android library that lets you create in a simple, fast and hassle-free way a CardView in which you can insert your custom layout and just expand and collapse without even writing a single Java/Kotlin line of code.
8 |
9 | This component follows the [Material Design Guidelines](https://material.io/guidelines/).
10 |
11 | ## Demo
12 |
13 | Get it on the [Google Play Store](https://play.google.com/store/apps/details?id=com.alessandrosperotti.expandablecardviewexample).
14 |
15 | # Setup
16 |
17 | First of all, include the dependency in your app build.gradle:
18 |
19 | ```gradle
20 | compile 'com.alespero:expandable-cardview:0.8'
21 | ```
22 |
23 | Or get the aar in the [Releases](https://github.com/AleSpero/ExpandableCardView/releases) section.
24 |
25 | ## Declaring the view
26 |
27 | After you have the Library correctly setup, just declare the ExpandableCardView in your xml:
28 |
29 | ```xml
30 |
40 | ```
41 | The only required attributes are `inner_view` and `title`. The other attributes are optional.
42 |
43 | You can specify a custom title and icon on the header on the card by setting the attribute ```app:title``` and ```app:icon``` respectively.
44 |
45 | After you created the base xml, just create your custom layout and place it inside your ```layout``` folder.
46 |
47 | Now just pass your newly created layout resource to the ```app:inner_view``` attribute. By setting the attribute ```app:expandOnClick="true"``` the card will have a default behaviour (expand/collapse on click); By setting the `animationDuration` attribute you can set a custom animation time, and by setting the `startExpanded` attribute the card will be automatically expanded when inflated.
48 |
49 | Done! Now your ExpandableCardView is ready to roll.
50 |
51 | ## Usage
52 |
53 | If you want some basic Expandable Card without any custom behaviour, setting the view in the XML is enough. Otherwise just declare your ExpandableCardView in your Activity/Fragment and you're ready to use its methods.
54 |
55 | ### Java
56 | ```java
57 | ExpandableCardView card = findViewById(R.id.profile);
58 |
59 | //Do stuff here
60 | ```
61 | ### Kotlin
62 |
63 | ```kotlin
64 | val card : ExpandableCardView = findViewById(R.id.profile)
65 |
66 | //Do stuff here
67 | ```
68 |
69 | You can use ```expand()``` and ```collapse()``` to respectively expand and collapse the card, and use ```isExpanded()``` to check if the card is expanded or not.
70 | You can change the title and icon of the card dynamically by using ```setTitle()``` and ```setIcon()``` methods.
71 |
72 | You can also set an OnExpandedListener to the card:
73 |
74 | ### Java
75 | ```java
76 | card.setOnExpandedListener(new OnExpandedListener() {
77 | @Override
78 | public void onExpandChanged(View v, boolean isExpanded) {
79 | Toast.makeText(applicationContext, isExpanded ? "Expanded!" : "Collapsed!", Toast.LENGTH_SHORT).show();
80 | }
81 | });
82 | ```
83 | ### Kotlin
84 |
85 | ```kotlin
86 | card.setOnExpandedListener { view, isExpanded ->
87 | Toast.makeText(applicationContext, if(isExpanded) "Expanded!" else "Collapsed!", Toast.LENGTH_SHORT).show()
88 | }
89 | ```
90 | ## Contribute

92 | This library is still in its early stages, so feel free to contribute. I will review any Pull Request in 24-48 hours.
