Android webview实现QQ一键登录授权

Android webview实现QQ一键登录授权

最近公司要求的新需求，要实现webview中的的QQ登录，大脑没经过就习惯的百度，奈何找了两天的资料也没发现个完整的demo，只能自己写，好吧，还要去学JS，醉了。

public class MainActivity extends Activity {
    private static final String LOG_TAG = "WebViewDemo";
    private String url = "https://graph.qq.com/user/get_user_info";
    private String SCOPE = "https://graph.qq.com/user/get_user_info,get_user_profile,add_share,add_topic,list_album,upload_pic,add_album";//授权范围
    private WebView mWebView;

    private Handler mHandler = new Handler();
    private Activity thisActivity;
    /**
    *qq登录
    */ 

    private Tencent mTencent;
    public static QQAuth mQQAuth;
    public static String mAppid;
    //测试用的ID，可改成你的ID
    private String APP_ID = "222222";
    /**
     * 返回授权信息
     */
    private String code;
    private String openid;
    private String access_token;

    @SuppressLint("SetJavaScriptEnabled")
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.activity_main);

    // 启用一个新线程用于回调登录信息用
    final Context context = MainActivity.this;
    final Context ctxContext = context.getApplicationContext();
    mAppid = APP_ID; // 绑定ID
    mQQAuth = QQAuth.createInstance(mAppid, ctxContext);
    mTencent = Tencent.createInstance(mAppid, MainActivity.this);

        mWebView = (WebView) findViewById(R.id.webview);
        WebViewClient wvClient = new WebViewClient();
        mWebView.setWebViewClient(wvClient);
        mWebView.setWebChromeClient(new WebChromeClient() {
            public boolean onJsAlert(WebView view, String url, String message,
                    JsResult result) {
                return super.onJsAlert(view, url, message, result);
            }
        });

        WebSettings webSettings = mWebView.getSettings();
        webSettings.setSaveFormData(false);
        webSettings.setJavaScriptEnabled(true);
        webSettings.setDefaultTextEncodingName("utf-8");

        @JavascriptInterface
        public String getInterface(){
            return "android_js_interface";
        }
    }

最后要记得添加权限

<uses-permission android:name="android.permission.INTERNET" />

JS的代码：

function init() 

            {} 

        function wave(jsobjStr) { 

            document.getElementById("output").innerHTML="返回值："+jsobjStr; 

            alert("像服务器传入数据"); 

        } 

        function OnClick() 

        { 

            window.android_js_interface.Login(); 

        } 

    <input type="submit" value="QQ登录" onclick="window.android_js_interface.Login();"/>
