建议下载demo，照着开发文档看

1.首先要配置SDK，官网下载的，两个jar。

2.配置AndroidManifest.xml 的权限和两个Activity

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.iwtle.www.englishstudy">
<!--用户需要的权限--><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><!-- SDK2.1新增获取用户位置信息 --><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" /><uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.GET_TASKS" /><applicationandroid:allowBackup="true"android:icon="@mipmap/studylogo"android:label="@string/app_name"android:supportsRtl="true"android:theme="@style/AppTheme"><activity android:name=".ui.LoginActivity"><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity>
<!--需要配置的两个Activity--><activityandroid: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="Tencent101368807" /><!--这个APPid需要替换成自己的--></intent-filter></activity><activityandroid:name="com.tencent.connect.common.AssistActivity"android:configChanges="orientation|keyboardHidden"android:screenOrientation="behind"android:theme="@android:style/Theme.Translucent.NoTitleBar" /></application></manifest>

3.编写登录的代码。

3.1首先需要在onCreate初始化sdk

protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mTencent = Tencent.createInstance("101368807", this.getApplicationContext());}

3.2创建回调的函数。

IUiListener loginListener = new BaseUiListener() {@Overrideprotected void doComplete(JSONObject values) {Log.d("SDKQQAgentPref", "AuthorSwitch_SDK:" + SystemClock.elapsedRealtime());System.out.println("123456" + values.toString());}};private class BaseUiListener implements IUiListener {@Overridepublic void onComplete(Object response) {if (null == response) {return;}JSONObject jsonResponse = (JSONObject) response;if (null != jsonResponse && jsonResponse.length() == 0) {return;}doComplete((JSONObject) response);System.out.println("123456789" + response.toString());}protected void doComplete(JSONObject values) {}@Overridepublic void onError(UiError e) {System.out.println("12345678910" + e.errorDetail);}@Overridepublic void onCancel() {System.out.println("12345678910" + "onCancel");}}

3.3还需要一个回调的方法（如果要成功接收到回调）

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {Log.d("12346", "-->onActivityResult " + requestCode + " resultCode=" + resultCode);if (requestCode == Constants.REQUEST_LOGIN ||requestCode == Constants.REQUEST_APPBAR) {Tencent.onActivityResultData(requestCode, resultCode, data, loginListener);}super.onActivityResult(requestCode, resultCode, data);}

3.4最后登录的代码

    public void Login(View view) {System.out.println("我要登录了！！");if (!mTencent.isSessionValid()) {mTencent.login(this, "all", loginListener);}}

4.登录页面的整体源码

public class MainActivity extends AppCompatActivity {private Tencent mTencent;protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mTencent = Tencent.createInstance("101368807", this.getApplicationContext());}public void Login(View view) {System.out.println("我要登录了！！");if (!mTencent.isSessionValid()) {mTencent.login(this, "all", loginListener);}}protected void onActivityResult(int requestCode, int resultCode, Intent data) {Log.d("12346", "-->onActivityResult " + requestCode + " resultCode=" + resultCode);if (requestCode == Constants.REQUEST_LOGIN ||requestCode == Constants.REQUEST_APPBAR) {Tencent.onActivityResultData(requestCode, resultCode, data, loginListener);}super.onActivityResult(requestCode, resultCode, data);}IUiListener loginListener = new BaseUiListener() {@Overrideprotected void doComplete(JSONObject values) { //获取数据Log.d("SDKQQAgentPref", "AuthorSwitch_SDK:" + SystemClock.elapsedRealtime());System.out.println("123456" + values.toString());}};private class BaseUiListener implements IUiListener {@Overridepublic void onComplete(Object response) { //登录成功获取数据if (null == response) {return;}JSONObject jsonResponse = (JSONObject) response;if (null != jsonResponse && jsonResponse.length() == 0) {return;}doComplete((JSONObject) response);System.out.println("登录成功" + response.toString());Toast.makeText(MainActivity.this, "登录成功" + response.toString(), Toast.LENGTH_LONG).show();}protected void doComplete(JSONObject values) {}@Overridepublic void onError(UiError e) {//登录出错System.out.println("12345678910" + e.errorDetail);}@Overridepublic void onCancel() { //取消登录System.out.println("12345678910" + "onCancel");}}}

我发现再好的教程，如果你只是搜到，而不去敲一遍。永远都不会去好好写的。
