QQ第三方登录的详细教程

3 。 创建工程，将之前下载的SDK包解压放入libs文件夹下并添加入书库，以下是工程代码

 
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <Button  android:layout_width="match_parent" android:layout_height="wrap_content" android:text="点击登录" android:onClick="buttonLogin" android:layout_centerInParent="true" android:textSize="16sp" android:textColor="#f4736e"/>  
   RelativeLayout> 

package android.com.myapplication; import android.content.Intent; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.util.Log; import android.view.View; import android.widget.Toast; import com.tencent.connect.UserInfo; import com.tencent.connect.auth.Token; import com.tencent.connect.common.Constants; import com.tencent.tauth.IUiListener; import com.tencent.tauth.Tencent; import com.tencent.tauth.UiError; import org.json.JSONException; import org.json.JSONObject; public class MainActivity extends AppCompatActivity { 
    private static final String TAG = "MainActivity"; private static final String APP_ID = "";//官方获取的APPID private Tencent mTencent; private BaseUiListener mIUiListener; private UserInfo mUserInfo; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //传入参数APPID和全局Context上下文 mTencent = Tencent.createInstance(APP_ID,MainActivity.this.getApplicationContext()); } public void buttonLogin(View v){ /通过这句代码，SDK实现了的登录，这个方法有三个参数，第一个参数是context上下文，第二个参数SCOPO 是一个String类型的字符串，表示一些权限 官方文档中的说明：应用需要获得哪些API的权限，由“，”分隔。例如：SCOPE = “get_user_info,add_t”；所有权限用“all” 第三个参数，是一个事件监听器，IUiListener接口的实例，这里用的是该接口的实现类 */ mIUiListener = new BaseUiListener(); //all表示获取所有权限 mTencent.login(MainActivity.this,"all", mIUiListener); } / * 自定义监听器实现IUiListener接口后，需要实现的3个方法 * onComplete完成 onError错误 onCancel取消 */ private class BaseUiListener implements IUiListener{ 
    @Override public void onComplete(Object response) { Toast.makeText(MainActivity.this, "授权成功", Toast.LENGTH_SHORT).show(); Log.e(TAG, "response:" + response); JSONObject obj = (JSONObject) response; try { String openID = obj.getString("openid"); String accessToken = obj.getString("access_token"); String expires = obj.getString("expires_in"); mTencent.setOpenId(openID); mTencent.setAccessToken(accessToken,expires); Token Token = mTencent.getToken(); mUserInfo = new UserInfo(getApplicationContext(),Token); mUserInfo.getUserInfo(new IUiListener() { @Override public void onComplete(Object response) { Log.e(TAG,"登录成功"+response.toString()); } @Override public void onError(UiError uiError) { Log.e(TAG,"登录失败"+uiError.toString()); } @Override public void onCancel() { Log.e(TAG,"登录取消"); } }); } catch (JSONException e) { e.printStackTrace(); } } @Override public void onError(UiError uiError) { Toast.makeText(MainActivity.this, "授权失败", Toast.LENGTH_SHORT).show(); } @Override public void onCancel() { Toast.makeText(MainActivity.this, "授权取消", Toast.LENGTH_SHORT).show(); } } / * 在调用Login的Activity或者Fragment中重写onActivityResult方法 * @param requestCode * @param resultCode * @param data */ @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if(requestCode == Constants.REQUEST_LOGIN){ Tencent.onActivityResultData(requestCode,resultCode,data,mIUiListener); } super.onActivityResult(requestCode, resultCode, data); } } 

 
    <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="android.com.myapplication">  
    <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <application  android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" />  
   intent-filter>  
   activity>  
    <activity  android:name="com.tencent.tauth.AuthActivity" android:launchMode="singleTask" android:noHistory="true" > <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:scheme="tencent" />

   activity> <activity android:name="com.tencent.connect.common.AssistActivity" android:theme="@android:style/Theme.Translucent.NoTitleBar" android:screenOrientation="portrait"/>  
   application>  
   manifest> 

然后安装到手机就可以了，这个APP ID每次我得到都不一样，我没想太多，反正都能用，客观也可以使用我的APP ID试一下。（也许APP ID有限期吧）

下次再见
