前言
寫了上一篇文章，講了下這個實現天氣預報的使用內容，現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。
聚合數據SDK配置
- 將juhe_sdk_v_X_X.jar以及armeabi文件夾(內包含libJuheSDK_v_X_X.so)添加到工程中libs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.
- 初始化聚合數據SDK
import android.app.Application;
public class MyApplication extends Application {@Overridepublic void onCreate() {
super.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() {
super.onCreate();JuheSDKInitializer.initialize(getApplicationContext());}
}
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;
private ArrayList<CityItem> mSearchCityList;
private CityAdapter mCityAdapter;
@Overrideprotected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.citylist);ButterKnife.bind(
this);mSupportCityList =
new ArrayList<CityItem>();mSearchCityList =
new ArrayList<CityItem>();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();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)) {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: 第一個參數 當前請求的context 第二個參數 接口id 第三二個參數 接口請求的url 第 四個參數 接口請求的方式* 第五個參數 接口請求的參數,鍵值對com.thinkland.sdk.android.Parameters類型; 第六個參數* 請求的回調方法,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 {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);mCityAdapter.notifyDataSetChanged();}}
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);
super.onPause();}
}
聚合數據針對支持的城市返回的JSON數據格式為
{
“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/區名稱/
},
{
“id”:”2”,
“province”:”北京”,
“city”:”北京”,
“district”:”海淀”
},
}
}
按照這種格式解析出JSON數據

有看不懂的內容可以留言，晚上統一回復。
介紹一個Intellij插件 —– Gson Format, 通過Json格式快速生成Java Bean類，提高開發效率
其實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的興趣，可以去多了解一下。
謝謝。
