QQ登录是一个非常简单的一个第三方应用，现在，我们就来实现一个QQ登录

首先下载两个jar包   这里上传不了jar包，所以可以到我的github中下载工程中libs中的两个jar包

打代码前，先把这些东西写上：

private static final String TAG = "MainActivity";

private static final String APP_ID = "1105602574";//官方获取的APPID

private Tencent mTencent;

private BaseUiListener mIUiListener;

private UserInfo mUserInfo;

在AndroidManifest.xml中加入权限

android:name="com.tencent.tauth.AuthActivity"

android:launchMode="singleTask"

android:noHistory="true" >

android:theme="@android:style/Theme.Translucent.NoTitleBar"

android:screenOrientation="portrait"/>

Xml布局中的

xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:app="http://schemas.android.com/apk/res-auto"

android:orientation="vertical"

xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"

android:layout_height="match_parent" tools:context="com.bwei.czx.czx0914qq.MainActivity">

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="登录"

android:id="@+id/login"/>

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:id="@+id/name"/>

android:layout_width="100dp"

android:layout_height="80dp"

android:id="@+id/img"/>

下面开始MainActivity中的代码

package com.bwei.czx.czx0914qq;

import android.content.Intent;

import android.os.Bundle;

import android.support.v7.app.AppCompatActivity;

import android.util.Log;

import android.view.View;

import android.widget.Button;

import android.widget.ImageView;

import android.widget.TextView;

import android.widget.Toast;

import com.nostra13.universalimageloader.core.ImageLoader;

import com.nostra13.universalimageloader.core.ImageLoaderConfiguration;

import com.tencent.connect.UserInfo;

import com.tencent.connect.auth.QQToken;

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 = "1105602574";//官方获取的APPID

private Tencent mTencent;

private BaseUiListener mIUiListener;

private UserInfo mUserInfo;

private Button login;

private TextView name;

private ImageView img;

@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());

initView();

login.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

mIUiListener = new BaseUiListener();

//all表示获取所有权限

mTencent.login(MainActivity.this,"all", mIUiListener);

mUserInfo = new UserInfo(MainActivity.this, mTencent.getQQToken()); //获取用户信息

mUserInfo.getUserInfo(mIUiListener);

}

});

}

private void initView() {

login = (Button) findViewById(R.id.login);

name = (TextView) findViewById(R.id.name);

img = (ImageView) findViewById(R.id.img);

}

/**

* 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);

QQToken qqToken = mTencent.getQQToken();

mUserInfo = new UserInfo(getApplicationContext(),qqToken);

mUserInfo.getUserInfo(new IUiListener() {

@Override

public void onComplete(Object response) {

Log.e(TAG,"登录成功"+response.toString());

if(response == null){

return;

}

try {

JSONObject jo = (JSONObject) response;

Toast.makeText(MainActivity.this, "登录成功",

Toast.LENGTH_LONG).show();

String nickName = jo.getString("nickname");

String figureurl_1= jo.getString("figureurl_1");

name.setText(nickName);

ImageLoaderConfiguration configuration = new ImageLoaderConfiguration.Builder(MainActivity.this).build();

ImageLoader.getInstance().init(configuration);

ImageLoader.getInstance().displayImage(figureurl_1,img);

} catch (Exception e) {

// TODO: handle exception

}

}

@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();

}

}

@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);

}

}

下面为显示效果

qq登录完成！
