在app module中的src/main/assets目录下我们准备了两个json文件：

destination.json如下：

{

"main/tabs/sofa": {

"isFragment": true,

"asStarter": false,

"needLogin": false,

"pageUrl": "main/tabs/sofa",

"className": "com.test.ppjoke.ui.notifications.NotificationsFragment",

"id": 448706824

},

"main/tabs/dash": {

"isFragment": true,

"asStarter": false,

"needLogin": false,

"pageUrl": "main/tabs/dash",

"className": "com.test.ppjoke.ui.dashboard.DashboardFragment",

"id": 938694224

},

"main/tabs/home": {

"isFragment": true,

"asStarter": true,

"needLogin": false,

"pageUrl": "main/tabs/home",

"className": "com.test.ppjoke.ui.home.HomeFragment",

"id": 509754652

},

"main/tabs/my": {

"isFragment": true,

"asStarter": false,

"needLogin": false,

"pageUrl": "main/tabs/my",

"className": "com.test.ppjoke.ui.my.MyFragment",

"id": 750793084

}

}

对应的destination的javabean文件：

public class Destination {

public String pageUrl;

public int id;

public boolean needLogin;

public boolean asStarter;

public boolean isFragment;

public String className;

}

main_tabs_config.json如下：

{

"activeColor": "#333333",

"inActiveColor": "#666666",

"selectTab": 0,

"tabs": [

{

"size": 24,

"enable": true,

"index": 0,

"pageUrl": "main/tabs/home",

"title": "首页"

},

{

"size": 24,

"enable": true,

"index": 1,

"pageUrl": "main/tabs/sofa",

"title": "沙发"

},

{

"size": 40,

"enable": true,

"index": 2,

"tintColor": "#ff678f",

"pageUrl": "main/tabs/publish",

"title": ""

},

{

"size": 24,

"enable": true,

"index": 3,

"pageUrl": "main/tabs/dash",

"title": "发现"

},

{

"size": 24,

"enable": true,

"index": 4,

"pageUrl": "main/tabs/my",

"title": "我的"

}

]

}

对应的BottomBar的JavaBean文件如下：

import java.util.List;

public class BottomBar {

/**

* activeColor : #333333

* inActiveColor : #666666

* tabs : [{"size":24,"enable":true,"index":0,"pageUrl":"main/tabs/home","title":"首页"},{"size":24,"enable":true,"index":1,"pageUrl":"main/tabs/sofa","title":"沙发"},{"size":40,"enable":true,"index":2,"tintColor":"#ff678f","pageUrl":"main/tabs/publish","title":""},{"size":24,"enable":true,"index":3,"pageUrl":"main/tabs/find","title":"发现"},{"size":24,"enable":true,"index":4,"pageUrl":"main/tabs/my","title":"我的"}]

*/

public String activeColor;

public String inActiveColor;

public List tabs;

public int selectTab;//底部导航栏默认选中项

public static class Tab {

/**

* size : 24

* enable : true

* index : 0

* pageUrl : main/tabs/home

* title : 首页

* tintColor : #ff678f

*/

public int size;

public boolean enable;

public int index;

public String pageUrl;

public String title;

public String tintColor;

}

}

sBottomBar = JSON.parseObject(content, BottomBar.class);

}

return sBottomBar;

}
