五个页面的基类BasePager
- BasePager的布局base_pager.xml
- 标题栏： RelativeLayout
- 内容部分： FrameLayout
- BasePager的方法
initView(),用于初始化公共部分视图，并且初始化加载子视图的FrameLayout
initData()初始化数据，当孩子需要初始化数据，或者绑定数据，联网请求数据并且绑定的时候，重写该方法
五个页面的实现
HomePager,
NewsCenterPager,
SmartServicePager,
GovaffairPager
SettingPager都继承BasePager
重写initData方法 ，添加子视图，并且绑定数据
配置新闻中心的联网请求
联网请求的ip和端口,web_home为服务器资源文件
public static final String BASE_URL = "http://192.168.1.100:80/web_home";
新闻中心的网络地址
public static final String NEWSCENTER_PAGER_URL = BASE_URL+"/static/api/news/categories.json";
使用OKHttp联网请求数据
private void getDataFromNet()
{
OkHttpUtils
.get()
.url(Constants.NEWSCENTER_PAGER_URL)
.build()
.execute(new StringCallback()
{
/**
* 当请求失败的时候回调
* @param call
* @param e
* @param id
*/
@Override
public void onError(Call call, Exception e, int id)
{
Log.e(TAG, "新闻中心请求失败==" + e.getMessage());
}
/**
* 当联网成功的时候回调
* @param response 请求成功的数据
* @param id
*/
@Override
public void onResponse(String response, int id)
{
Log.e(TAG, "新闻中心请求成功==" + response);
//解析数据
processData(response);
}
});
}
在NewsApplication中初始化OkhttpUtils
private void initOkhttpClient()
{
OkHttpClient okHttpClient = new OkHttpClient.Builder()
// .addInterceptor(new LoggerInterceptor("TAG"))
.connectTimeout(10000L, TimeUnit.MILLISECONDS)
.readTimeout(10000L, TimeUnit.MILLISECONDS)
//其他配置
.build();
OkHttpUtils.initClient(okHttpClient);
}
在NewsCenterPager类的initData()方法中先得到缓存数据，若没有缓存数据则联网请求数据
//得到缓存数据
String saveJson = CacheUtils.getString(context, Constants.NEWSCENTER_PAGER_URL);//""
if (!TextUtils.isEmpty(saveJson))
{
processData(saveJson);
}
//联网请求数据
getDataFromNet();
使用使用OKHttp联网请求数据成功后，缓存数据
/**
* 当联网成功的时候回调
* @param response 请求成功的数据
* @param id
*/
@Override
public void onResponse(String response, int id)
{
Log.e(TAG, "新闻中心请求成功==" + response);
//缓存数据
CacheUtils.putString(context, Constants.NEWSCENTER_PAGER_URL, response);
//解析数据
processData(response);
}
});
CacheUtils类中缓存数据及获取缓存数据的方法
/**

* @param key
* @param value

public static void putString(Context context, String key, String value)
{

ViewPagerIndicator的使用
下载地址：
https://github.com/JakeWharton/ViewPagerIndicator
2.解压导入Android studio运行案例ViewPagerIndicator
3.开始集成-关联ViewPagerIndicator的库
4.写布局文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.viewpagerindicator.TabPageIndicator
android:id="@+id/tabPageIndicator"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
5.写代码
//ViewPager和TabPageIndicator关联
tabPageIndicator.setViewPager(viewPager);
//主页以后监听页面的变化 ，TabPageIndicator监听页面的变化
6.在适配器中重写getPagerTitle()
@Override
public CharSequence getPageTitle(int position) {
return children.get(position).getTitle();
}
7.设置样式
<activity android:name=".activity.MainActivity"
android:theme="@style/Theme.PageIndicatorDefaults"
></activity>
8.修改样式
<style name="Widget.TabPageIndicator" parent="Widget">
<item name="android:gravity">center</item>
<item name="android:background">@drawable/vpi__tab_indicator</item>
<item name="android:paddingLeft">22dip</item>
<item name="android:paddingRight">22dip</item>
<item name="android:paddingTop">12dp</item>
<item name="android:paddingBottom">12dp</item>
<item name="android:textAppearance">@style/TextAppearance.TabPageIndicator</item>
<item name="android:textSize">14sp</item>
<item name="android:textColor">@drawable/vpi__tab_textcolor_indicator</item>
<item name="android:maxLines">1</item>
</style>
9.修改背景vpi__tab_indicator.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@android:color/transparent" />

<item android:state_focused="true" android:state_selected="true" android:state_pressed="true" android:drawable="@drawable/news_tab_item_bg_select" />
</selector>
10.修改文字的颜色vpi__tab_textcolor_indicator.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Non focused states -->

<item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:color="@android:color/holo_red_light" />
<!-- Pressed -->
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:color="@android:color/black" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="true" android:color="@android:color/holo_red_light" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:color="@android:color/black" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="true" android:color="@android:color/holo_red_light" />
</selector>
