前言

寫了上一篇文章，講了下這個實(shí)現(xiàn)天氣預(yù)報(bào)的使用內(nèi)容，現(xiàn)在又到了看代碼的時候，主要還是貼代碼，然后添加足夠的注釋。

聚合數(shù)據(jù)SDK配置

• 將juhe_sdk_v_X_X.jar以及armeabi文件夾(內(nèi)包含libJuheSDK_v_X_X.so)添加到工程中l(wèi)ibs文件夾下
• 打開Moudle setting -> app -> Dependencies,添加juhe_sdk_v_X_X.jar,
• 在AndroidManifest.xml中,加入所需權(quán)限:

<uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

• 添加所申請的openid(這個是在Juhe官網(wǎng)上申請的).在繼承Application類之后, 在AndroidManifest.xml中,加入android:name屬性,值為繼承Application的類的路徑.
• 初始化聚合數(shù)據(jù)SDK

import android.app.Application;public class MyApplication extends Application {@Overridepublic void onCreate() {// TODO Auto-generated method stubsuper.onCreate();JuheSDKInitializer.initialize(getApplicationContext());} }

工程代碼

MyApplication.java

package com.onlyloveyd.weather; import android.app.Application; import com.thinkland.sdk.android.JuheSDKInitializer; public class MyApplication extends Application {@Overridepublic void onCreate() {// TODO Auto-generated method stubsuper.onCreate();JuheSDKInitializer.initialize(getApplicationContext());//初始化Juhe數(shù)據(jù)SDK} }

城市選擇界面
ChooseCityActivity.java

package com.onlyloveyd.weather; import ......;public class ChooseCityActivity extends Activity {public static final String TAG = "ChooseCityActivity";@Bind(R.id.tv_choose_city_title)TextView tvChooseCityTitle;@Bind(R.id.et_search_city)EditText etSearchCity;@Bind(R.id.tv_hotcity)TextView tvHotcity;@Bind(R.id.gv_hotcity)GridView gvHotcity;private ArrayList<CityItem> mSupportCityList;//所有城市Listprivate ArrayList<CityItem> mSearchCityList;//城市查詢結(jié)果Listprivate CityAdapter mCityAdapter;//城市GridView的Adapter@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.citylist);//城市選擇界面ButterKnife.bind(this);//依賴注入mSupportCityList = new ArrayList<CityItem>();mSearchCityList = new ArrayList<CityItem>();//設(shè)置帶shape模式的編輯框的背景顏色//GradientDrawable myGrad = (GradientDrawable)mSearchEditView.getBackground();//myGrad.setColor(getResources().getColor(R.color.choosecitysearchbackground));//給城市名編譯框添加文本變化的觀察者etSearchCity.addTextChangedListener(new TextWatcher() {@Overridepublic void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) { }@Overridepublic void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {mSearchCityList.clear();//城市查詢結(jié)果list清空String searchkey = charSequence.toString();Log.e(TAG, " city size " + mSupportCityList.size());for (int j = 0; j < mSupportCityList.size(); j++) {CityItem item = mSupportCityList.get(j);if (searchkey.contains(item.getDistrict()) || item.getDistrict().contains(searchkey)) {//遍歷查詢mSearchCityList.add(item);}}mCityAdapter.setCityList(mSearchCityList);mCityAdapter.notifyDataSetChanged();}@Overridepublic void afterTextChanged(Editable editable) {}});mCityAdapter = new CityAdapter(this, mSupportCityList);gvHotcity.setAdapter(mCityAdapter);getSupportCity(this);}private void getSupportCity(Context context) {/**Juhe SDK 封裝的方法* 請求的方法 參數(shù): 第一個參數(shù) 當(dāng)前請求的context 第二個參數(shù) 接口id 第三二個參數(shù) 接口請求的url 第 四個參數(shù) 接口請求的方式* 第五個參數(shù) 接口請求的參數(shù),鍵值對com.thinkland.sdk.android.Parameters類型; 第六個參數(shù)* 請求的回調(diào)方法,com.thinkland.sdk.android.DataCallBack;* */JuheData.executeWithAPI(context, 39, "http://v.juhe.cn/weather/citys", JuheData.GET, null, new DataCallBack() {@Overridepublic void onSuccess(int statusCode, String responseString) {try {//解析JSON數(shù)據(jù)JSONObject jsonObject = new JSONObject(responseString);JSONArray result = jsonObject.getJSONArray("result");for (int i = 0; i < result.length(); i++) {JSONObject object = (JSONObject) result.get(i);CityItem item = new CityItem(object.getString("id"), object.getString("province"), object.getString("city"), object.getString("district"));mSupportCityList.add(item);//查詢結(jié)果添加mCityAdapter.notifyDataSetChanged();//notify數(shù)據(jù)變化}} catch (JSONException e) {e.printStackTrace();}}@Overridepublic void onFinish() {}@Overridepublic void onFailure(int statusCode, String responseString, Throwable throwable) {Log.e(TAG, responseString);}});}@Overrideprotected void onResume() {super.onResume();}@Overrideprotected void onPause() {etSearchCity.setText(null);//避免onBackPress的時候編輯框中還有數(shù)據(jù)super.onPause();} }

聚合數(shù)據(jù)針對支持的城市返回的JSON數(shù)據(jù)格式為
{
“resultcode”:”200”,
“reason”:”successed”,
“result”:[
{
“id”:”1”, /城市ID/
“province”:”北京”,/省份名稱/
“city”:”北京”, /城市/
“district”:”北京” /城市/區(qū)名稱/
},
{
“id”:”2”,
“province”:”北京”,
“city”:”北京”,
“district”:”海淀”
},
}
}
按照這種格式解析出JSON數(shù)據(jù)

具體的內(nèi)容請查閱源代碼：

有看不懂的內(nèi)容可以留言，晚上統(tǒng)一回復(fù)。
介紹一個Intellij插件 —– Gson Format, 通過Json格式快速生成Java Bean類，提高開發(fā)效率
其實(shí)有很多很好用的插件可供選擇，不僅可以提高效率，還可以增加自己對開發(fā)的興趣，可以去多了解一下。

謝謝。
