How This API Document Is Organized

65 |
This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.
66 |
67 |
68 |
    69 |
  • 70 |

    Package

    71 |

    Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain six categories:

    72 |
      73 |
    • Interfaces (italic)
      • 74 |
    • Classes
      • 75 |
    • Enums
      • 76 |
    • Exceptions
      • 77 |
    • Errors
      • 78 |
    • Annotation Types
      • 79 |
    80 |
    • 81 |
  • 82 |

    Class/Interface

    83 |

    Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:

    84 |
      85 |
    • Class inheritance diagram
      • 86 |
    • Direct Subclasses
      • 87 |
    • All Known Subinterfaces
      • 88 |
    • All Known Implementing Classes
      • 89 |
    • Class/interface declaration
      • 90 |
    • Class/interface description
      • 91 |
    92 |
      93 |
    • Nested Class Summary
      • 94 |
    • Field Summary
      • 95 |
    • Constructor Summary
      • 96 |
    • Method Summary
      • 97 |
    98 |
      99 |
    • Field Detail
      • 100 |
    • Constructor Detail
      • 101 |
    • Method Detail
      • 102 |
    103 |

    Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.

    104 |
    • 105 |
  • 106 |

    Annotation Type

    107 |

    Each annotation type has its own separate page with the following sections:

    108 |
      109 |
    • Annotation Type declaration
      • 110 |
    • Annotation Type description
      • 111 |
    • Required Element Summary
      • 112 |
    • Optional Element Summary
      • 113 |
    • Element Detail
      • 114 |
    115 |
    • 116 |
  • 117 |

    Enum

    118 |

    Each enum has its own separate page with the following sections:

    119 |
      120 |
    • Enum declaration
      • 121 |
    • Enum description
      • 122 |
    • Enum Constant Summary
      • 123 |
    • Enum Constant Detail
      • 124 |
    125 |
    • 126 |
  • 127 |

    Tree (Class Hierarchy)

    128 |

    There is a Class Hierarchy page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with java.lang.Object. The interfaces do not inherit from java.lang.Object.

    129 |
      130 |
    • When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.
      • 131 |
    • When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.
      • 132 |
    133 |
    • 134 |
  • 135 |

    Deprecated API

    136 |

    The Deprecated API page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.

    137 |
    • 138 |
  • 139 |

    Index

    140 |

    The Index contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.

    141 |
    • 142 |
  • 143 |

    Prev/Next

    144 |

    These links take you to the next or previous class, interface, package, or related page.

    145 |
    • 146 |
  • 147 |

    Frames/No Frames

    148 |

    These links show and hide the HTML frames. All pages are available with or without frames.

    149 |
    • 150 |
  • 151 |

    All Classes

    152 |

    The All Classes link shows all classes and interfaces except non-static nested types.

    153 |
    • 154 |
  • 155 |

    Serialized Form

    156 |

    Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.

    157 |
    • 158 |
  • 159 |

    Constant Field Values

    160 |

    The Constant Field Values page lists the static final fields and their values.

You can see a video of the example working here: 13 | 14 | [![a video of the example working here](https://img.youtube.com/vi/moWaruuaEP0/0.jpg)](https://www.youtube.com/watch?v=moWaruuaEP0) 15 | 16 | 17 | 18 | ## Adding the Library to gradle file 19 | ```gradle 20 | dependencies { 21 | compile 'com.diegodobelo.expandingview:expanding-view:0.9.4' 22 | } 23 | ``` 24 | 25 | ## Using the Library 26 | ### Layouts 27 | First of all include the ExpandingList in your Activity (or Fragment) layout. This will be the list of items (ExpandItem): 28 | 29 | ```xml 30 | 34 | ``` 35 | 36 | Now create a new layout (xml) file to represent the item (such as `res/layout/expanding_item.xml`). This will be the Item (header) that can be expanded to show sub items: 37 | 38 | ```xml 39 | 43 | 50 | 51 | ``` 52 | 53 | Create another layout file to represent the sub items (such as `/res/expanding_sub_item.xml`). This will be the sub items that will be shown when the Item is expanded: 54 | 55 | ```xml 56 | 60 | 68 | 69 | ``` 70 | 71 | Now create a layout file (such as `/res/expanding_layout.xml`) to represent the whole item, including both item layout and sub item layout. We will explain each custom attribute later: 72 | 73 | ```xml 74 | 88 | ``` 89 | 90 | Note that we included `expanding_item` and `expanding_sub_item` layouts created before. 91 | 92 | ### Java code 93 | 94 | Now that you have all the required layouts you are able to use them in Java code. Let's start inflating the ExpandingList: 95 | 96 | ```java 97 | ExpandingList expandingList = (ExpandingList) findViewById(R.id.expanding_list_main); 98 | ``` 99 | 100 | Create a new ExpandingItem in the ExpandingList. This method receives the `expanding_layout` created before. Yes! We can have different layouts for different items in the same list. The items will be created based on `expanding_item` layout and the sub items will be created based on `expanding_sub_item` layout: 101 | 102 | ```java 103 | ExpandingItem item = expandingList.createNewItem(R.layout.expanding_layout); 104 | 105 | /*ExpandingItem extends from View, so you can call 106 | findViewById to get any View inside the layout*/ 107 | (TextView) item.findViewById(R.id.title)).setText("It Works!!"); 108 | ``` 109 | 110 | Let's create the sub items. There is a method to create items in batch: 111 | 112 | ```java 113 | //This will create 5 items 114 | item.createSubItems(5); 115 | 116 | //get a sub item View 117 | View subItemZero = item.getSubItemView(0); 118 | ((TextView) subItemZero.findViewById(R.id.sub_title)).setText("Cool"); 119 | 120 | View subItemOne = item.getSubItemView(1); 121 | ((TextView) subItemOne.findViewById(R.id.sub_title)).setText("Awesome"); 122 | 123 | ... 124 | 125 | ``` 126 | 127 | For each item you can set the indicator color and the indicator icon: 128 | 129 | ```java 130 | item.setIndicatorColorRes(R.color.blue); 131 | item.setIndicatorIconRes(R.drawable.ic_icon); 132 | 133 | ``` 134 | ### ExpandingItem layout attributes 135 | 136 | Attribute Name | Type | Default Value | Meaning | Mandatory 137 | ---------------------- | ------------ | ------------- | --------------------------------------------------------------------| -------- 138 | item_layout | reference | | The layout for the Item (header). | Yes 139 | sub_item_layout | reference | | The layout for the sub items. | Yes 140 | separator_layout | reference | | A layout to separate items. | No 141 | indicator_size | dimension | 0dp | The indicator size in dp. | No 142 | indicator_margin_left | dimension | 0dp | The margin between the indicator and its left. | No 143 | indicator_margin_right | dimension | 0dp | The margin between the indicator and its right. | No 144 | show_indicator | boolean | true | true if you want to show the indicator. false otherwise. | No 145 | show_animation | boolean | true | true if you want to show animations. false otherwise. | No 146 | start_collapsed | boolean | true | true if you want the sub views to start collapsed. false otherwise. | No 147 | animation_duration | integer | 300ms | The animations duration in milliseconds. | No 148 | 149 | ## ExpandingList public methods 150 | 151 | ##### `public void createNewItem(int layoutId)` 152 | 153 | Method to create and add a new item. 154 | 155 | * **Parameters:** `layoutId` — The item Layout 156 | 157 | ##### `public void removeItem(ExpandingItem item)` 158 | 159 | Method to remove an item. 160 | 161 | * **Parameters:** `item` — The item to be removed, of type {@link ExpandingItem} 162 | 163 | ##### `public void removeAllViews()` 164 | 165 | Method to remove all items. 166 | 167 | ##### `ExpandingItem getItemByIndex(int index)` 168 | 169 | Method to get an Item from the ExpandingList by its index. 170 | 171 | * **Parameters:** `index` — The index of the item. 172 | * **Returns:** An {@link ExpandingItem} in the list. 173 | 174 | ##### `public int getItemsCount()` 175 | 176 | Return how many items exists in the list. 177 | 178 | * **Returns:** Items count. 179 | 180 | ## ExpandingItem public methods 181 | 182 | ##### `public void setStateChangedListener(OnItemStateChanged listener)` 183 | 184 | Set a listener to listen item stage changed. 185 | 186 | * **Parameters:** `listener` — The listener of type {@link OnItemStateChanged} 187 | 188 | ##### `public boolean isExpanded()` 189 | 190 | Tells if the item is expanded. 191 | 192 | * **Returns:** true if expanded. false otherwise. 193 | 194 | ##### `public int getSubItemsCount()` 195 | 196 | Returns the count of sub items. 197 | 198 | * **Returns:** The count of sub items. 199 | 200 | ##### `public void collapse()` 201 | 202 | Collapses the sub items. 203 | 204 | ##### `public void toggleExpanded()` 205 | 206 | Expand or collapse the sub items. 207 | 208 | ##### `public void setIndicatorColorRes(int colorRes)` 209 | 210 | Set the indicator color by resource. 211 | 212 | * **Parameters:** `colorRes` — The color resource. 213 | 214 | ##### `public void setIndicatorColor(int color)` 215 | 216 | Set the indicator color by color value. 217 | 218 | * **Parameters:** `color` — The color value. 219 | 220 | ##### `public void setIndicatorIconRes(int iconRes)` 221 | 222 | Set the indicator icon by resource. 223 | 224 | * **Parameters:** `iconRes` — The icon resource. 225 | 226 | ##### `public void setIndicatorIcon(Drawable icon)` 227 | 228 | Set the indicator icon. 229 | 230 | * **Parameters:** `icon` — Drawable of the indicator icon. 231 | 232 | ##### `@Nullable public View createSubItem()` 233 | 234 | Creates a sub item based on sub_item_layout Layout, set as ExpandingItem layout attribute. 235 | 236 | * **Returns:** The inflated sub item view. 237 | 238 | ##### `@Nullable public View createSubItem(int position)` 239 | 240 | Creates a sub item based on sub_item_layout Layout, set as ExpandingItem layout attribute.
