Android 實現QQ第三方登錄

Android 實現QQ第三方登錄

Android 實現QQ第三方登錄

首先肯定是去下載SDK和DEMO

http://wiki.open.qq.com/wiki/mobile/SDK下載

本文是我自己整合後的簡單DEMO。

先看下效果圖吧

原理：我們要使用QQ登錄我們的應用，不是不用註冊，是我們在後臺爲用戶註冊了，但是用戶不知道，註冊需要唯一標識，上圖的那串字母與數字的組合就是我們要獲得的唯一標識：OpenID.<喎�"http://www.2cto.com/kf/ware/vc/" target="_blank" class="keylink">vcD4KPHA+uPrXxbT6wuvAtMu1sMmhozwvcD4KPHA+ytfPyKOsztLDx9KqvNPU2G9wZW5fc2RrLmphcrrNbXRhLXNkay0xLjAwLmphctXiwb249rzcsPzLs7Hjv7TPws7S19y5stPDtb21xMDgPC9wPgo8cD48aW1nIHNyYz0="http://www.2cto.com/uploadfile/Collfiles/20140910/201409100906079.jpg" alt="\">

其中，AppConstant中是用來放置APPID的，由於考慮到還可能引入其他第三方登錄，爲方便管理，故創建此類。Util是根據路徑從網上獲取圖片的處理類

好了進入主題

首先在AndroidManifest.xml中進行兩個定義如果不定義是不行的

?

1 2 3 4 5 6 7 8 9 10 11 12

<intent-filter>                                     <category android:name="android.intent.category.DEFAULT">                 <category android:name="android.intent.category.BROWSABLE">                   <data android:scheme="tencent222222"><!--—注意在這裏用你的appid替換222222 ---->             </data></category></category></action></intent-filter>         </activity>           </activity>

然後是兩個權限

?

1 2 3

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

接下來是佈局文件，activity_main.xml登錄按鈕，獲取頭像、暱稱、openid的textview

?

1 2 3 4 5 6 7 8

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical">     <button android:id="@+id/login" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="登錄">     <imageview android:id="@+id/user_logo" android:layout_width="wrap_content" android:layout_height="wrap_content">     <textview android:id="@+id/user_nickname" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textcolor="#80505050" android:textsize="18sp">     <textview android:id="@+id/user_openid" android:layout_width="wrap_content" android:layout_height="wrap_content">        </textview></textview></imageview></button></linearlayout>

然後是MainActivity

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81

public class MainActivity extends Activity implements OnClickListener {     TextView openidTextView;     TextView nicknameTextView;     Button loginButton;     ImageView userlogo;     private Tencent mTencent;     public static QQAuth mQQAuth;       public static String mAppid;       public static String openidString;       public static String nicknameString;       public static String TAG="MainActivity";       Bitmap bitmap = null;     @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);         //用來登錄的Button         loginButton=(Button)findViewById(R.id.login);         loginButton.setOnClickListener(this);         //用來顯示OpenID的textView         openidTextView=(TextView)findViewById(R.id.user_openid);         //用來顯示暱稱的textview         nicknameTextView=(TextView)findViewById(R.id.user_nickname);        //用來顯示頭像的Imageview         userlogo=(ImageView)findViewById(R.id.user_logo);               }     public void onClick(View v) {         // TODO Auto-generated method stub         switch (v.getId()) {         case R.id.login:             LoginQQ();             break;           default:             break;         }     }     //這裏是調用QQ登錄的關鍵代碼     public void LoginQQ() {         //這裏的APP_ID請換成你應用申請的APP_ID，我這裏使用的是DEMO中官方提供的測試APP_ID 222222         mAppid = AppConstant.APP_ID;         //第一個參數就是上面所說的申請的APPID，第二個是全局的Context上下文，這句話實現了調用QQ登錄         mTencent = Tencent.createInstance(mAppid,getApplicationContext());         /**通過這句代碼，SDK實現了QQ的登錄，這個方法有三個參數，第一個參數是context上下文，第二個參數SCOPO 是一個String類型的字符串，表示一些權限         官方文檔中的說明：應用需要獲得哪些API的權限，由“，”分隔。例如：SCOPE = “get_user_info,add_t”；所有權限用“all”          第三個參數，是一個事件監聽器，IUiListener接口的實例，這裏用的是該接口的實現類 */         mTencent.login(MainActivity.this,"all", new BaseUiListener());                   }     /**當自定義的監聽器實現IUiListener接口後，必須要實現接口的三個方法，      * onComplete  onCancel onError      *分別表示第三方登錄成功，取消 ，錯誤。*/     private class BaseUiListener implements IUiListener {           public void onCancel() {             // TODO Auto-generated method stub                       }         public void onComplete(Object response) {             // TODO Auto-generated method stub             Toast.makeText(getApplicationContext(), "登錄成功", 0).show();             try {                 //獲得的數據是JSON格式的，獲得你想獲得的內容                 //如果你不知道你能獲得什麼，看一下下面的LOG                 Log.e(TAG, "-------------"+response.toString());                 openidString = ((JSONObject) response).getString("openid");                 openidTextView.setText(openidString);                 Log.e(TAG, "-------------"+openidString);                 //access_token= ((JSONObject) response).getString("access_token");              //expires_in = ((JSONObject) response).getString("expires_in");             } catch (JSONException e) {                 // TODO Auto-generated catch block                 e.printStackTrace();             }             /**到此已經獲得OpneID以及其他你想獲得的內容了             QQ登錄成功了，我們還想獲取一些QQ的基本信息，比如暱稱，頭像什麼的，這個時候怎麼辦？             sdk給我們提供了一個類UserInfo，這個類中封裝了QQ用戶的一些信息，我麼可以通過這個類拿到這些信息             如何得到這個UserInfo類呢？  */             QQToken qqToken = mTencent.getQQToken();             UserInfo info = new UserInfo(getApplicationContext(), qqToken);             //這樣我們就拿到這個類了，之後的操作就跟上面的一樣了，同樣是解析JSON

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80

info.getUserInfo(new IUiListener() {                   public void onComplete(final Object response) {                     // TODO Auto-generated method stub                     Log.e(TAG, "---------------111111");                     Message msg = new Message();                     msg.obj = response;                     msg.what = 0;                     mHandler.sendMessage(msg);                     Log.e(TAG, "-----111---"+response.toString());                     /**由於圖片需要下載所以這裏使用了線程，如果是想獲得其他文字信息直接                      * 在mHandler裏進行操作                      *                      */                     new Thread(){                           @Override                         public void run() {                             // TODO Auto-generated method stub                             JSONObject json = (JSONObject)response;                             try {                                 bitmap = Util.getbitmap(json.getString("figureurl_qq_2"));                             } catch (JSONException e) {                                 // TODO Auto-generated catch block                                 e.printStackTrace();                             }                             Message msg = new Message();                             msg.obj = bitmap;                             msg.what = 1;                             mHandler.sendMessage(msg);                         }                                           }.start();                 }                               public void onCancel() {                     Log.e(TAG, "--------------111112");                     // TODO Auto-generated method stub                                  }                 public void onError(UiError arg0) {                     // TODO Auto-generated method stub                     Log.e(TAG, "-111113"+":"+arg0);                 }                               });                       }           public void onError(UiError arg0) {             // TODO Auto-generated method stub                       }                         }     Handler mHandler = new Handler() {           @Override         public void handleMessage(Message msg) {             if (msg.what == 0) {                 JSONObject response = (JSONObject) msg.obj;                 if (response.has("nickname")) {                     try {                         nicknameString=response.getString("nickname");                                                   nicknameTextView.setText(nicknameString);                         Log.e(TAG, "--"+nicknameString);                     } catch (JSONException e) {                         // TODO Auto-generated catch block                         e.printStackTrace();                     }                 }             }else if(msg.what == 1){                 Bitmap bitmap = (Bitmap)msg.obj;                 userlogo.setImageBitmap(bitmap);                               }         }       };         }

上圖是登錄Q的返回LOG

上圖是我們獲得騰訊提供的UserInfo返回的LOG

然後是AppConstant.java

?

1 2 3

public class AppConstant {     public static String APP_ID="222222"; }

然後是Util.java

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

public class Util {     public static String TAG="UTIL";     public static Bitmap getbitmap(String imageUri) {         Log.v(TAG, "getbitmap:" + imageUri);         // 顯示網絡上的圖片         Bitmap bitmap = null;         try {             URL myFileUrl = new URL(imageUri);             HttpURLConnection conn = (HttpURLConnection) myFileUrl                     .openConnection();             conn.setDoInput(true);             conn.connect();             InputStream is = conn.getInputStream();             bitmap = BitmapFactory.decodeStream(is);             is.close();               Log.v(TAG, "image download finished." + imageUri);         } catch (IOException e) {             e.printStackTrace();             Log.v(TAG, "getbitmap bmp fail---");             return null;         }         return bitmap;     } }

至此全部代碼就在這裏了，我們獲得了OpenID這個唯一標識最關鍵的東西，然後看項目中
