qq授权登录实现步骤

第一步，下载qq授权登录的sdk

第二步：在清单文件中添加腾讯官方的activity ，具体代码在下方

Activity实现：

public class MainActivity extends Activity {

private static final String TAG = MainActivity.class.getName();

public static String mAppid;

private Button mNewLoginButton;

private TextView mUserInfo;

private ImageView mUserLogo;

public static QQAuth mQQAuth;

private UserInfo mInfo;

private Tencent mTencent;

private final String APP_ID = "222222";// 测试时使用，真正发布的时候要换成自己的APP_ID

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

Log.d(TAG, "-->onCreate");

// 固定竖屏

setContentView(R.layout.activity_main);

initViews();

}

@Override

protected void onStart() {

Log.d(TAG, "-->onStart");

final Context context = MainActivity.this;

final Context ctxContext = context.getApplicationContext();

mAppid = APP_ID;

mQQAuth = QQAuth.createInstance(mAppid, ctxContext);//初始化QQ权限组件

mTencent = Tencent.createInstance(mAppid, MainActivity.this);//初始化腾讯登录组件

super.onStart();

}

@Override

protected void onResume() {

Log.d(TAG, "-->onResume");

super.onResume();

}

@Override

protected void onPause() {

Log.d(TAG, "-->onPause");

super.onPause();

}

@Override

protected void onStop() {

Log.d(TAG, "-->onStop");

super.onStop();

}

@Override

protected void onDestroy() {

Log.d(TAG, "-->onDestroy");

super.onDestroy();

}

private void initViews() {

mNewLoginButton = (Button) findViewById(R.id.new_login_btn);

//这一步看着像是多余的直接mNewLoginButton.setOnClickListener(listener);是一样的效果

//你所需要的： 1->findviewbyid找到这个按钮，然后绑定点击事件
