如何在Android GITKIT中使用UIManager

Question

首先，请原谅我糟糕的英语，我正在寻找一些关于如何在Android GITKIT中使用UIManager来为用户身份验证生成自定义UI的示例代码或教程，但我没有找到任何东西。请给我指引谢谢

首先，这不是你的错，gitkit的文档也很少。至于实现本身，首先您需要将代码复制粘贴到此处(从the docs)：

public class MyLoginActivity extends Activity {

 private GitkitClient client;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     // If there is no signed in user, create a GitkitClient to start sign in flow.
     SignInCallbacks callbacks = new SignInCallbacks() {
         // Implement the onSignIn method of GitkitClient.SignInCallbacks interface.
         @Override
         public void onSignIn(IdToken idToken, GitkitUser gitkitUser) {
             // Send the idToken to the server. The server should issue a session cookie/token
             // for the app if the idToken is verified.
             authenticate(idToken.getTokenString());
             ...
         }

         // Implement the onSignInFailed method of GitkitClient.SignInCallbacks interface.
         @Override
         public void onSignInFailed() {
             // Handle the sign in failure.
             ...
         }
     }
     // The example suppose all necessary configurations are set in the AndroidManifest.xml.
     // You can also set or overwrite them by calling the corresponding setters on the
     // GitkitClientBuilder.
     client = GitkitClient.newBuilder(this, callbacks).setUiManager(new MyUiManger()).build();
     // Start sign in flow.
     client.startSignIn();
 }

 @Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
     if (client.handleActivityResult(requestCode, resultCode, data)) {
         // result is handled by GitkitClient.
         return;
     }
     // Otherwise, the result is not returned to GitkitClient and should be handled by the
     // activity.
     ...
 }

 @Override
 protected void onNewIntent(Intent intent) {
     if (client.handleIntent(intent)) {
         // intent is handled by the GitkitClient.
         return;
     }
     // Otherwise, the intent is not for GitkitClient and should be handled by the activity.
     ...
 }

}

然后你应该实现一个MyUIManger，并注意这个方法：

            @Override
        public void setRequestHandler(RequestHandler requestHandler) {
            //store requestHandler somewhere accessible. 
        }

因为这是您应该将所有UI输入发送到的对象。

关于MyUIManager的其余部分，按照here描述的接口，您应该在调用这些函数时更改屏幕，并将用户输入与相应的请求一起发送到requestHandler。

例如，当调用client.startSignIn()时，GitKitClient将调用MyUIManager.ShowStartSignIn方法，因此在该方法中，您应该显示相关的屏幕，并将输入发送到前面的RequestHandler。某物类似于：

//in MyUIManager:
        @Override
        public void showStartSignIn(GitkitUser.UserProfile userProfile) {
            //Show start login fragment
        }
//some where in the login fragment:
        @Override
        public void onClick(View view) {
            StartSignInRequest request = new StartSignInRequest();
            request.setEmail(email);
            request.setIdProvider(idProvider);
            mRequestHandler.handle(request);
        }
