Android实现QQ登录功能

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

网址：https://github.com/chengzexiang/qqlogin

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  

 Xml布局中的

下面开始MainActivity中的代码

  initView();

   @Override

      } 
      try {

 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); 
 } 
}
