我在使用Integer数据类型实现双向绑定时遇到了一些问题.

public class User {

    private String firstName;
    private String lastName;
    private int age;

    public User() {}

    public void setFirstName(String firstName) {
       this.firstName = firstName;
    }

    public String getFirstName() {
       return this.firstName;
    }

    public void setLastName(String lastName) {
       this.lastName = lastName;
    }

    public String getLastName() {
       return this.lastName;
    }

    public void setAge(int age) {
       this.age = age;
    }

    public int getAge() {
       return this.age;
    }

}

XML:

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">

    <data class="UserDataBinding">
        <variable
            name="user"

我正在构建一个使用语音命令执行某些功能的应用程序.我从这里得到了一些代码

private static final int SPEECH_REQUEST_CODE = 0;

// Create an intent that can start the Speech Recognizer activity
private void displaySpeechRecognizer() {
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
// Start the activity, the intent will be populated with the speech text
    startActivityForResult(intent, SPEECH_REQUEST_CODE);
}

// This callback is invoked when the Speech Recognizer returns.
// This is where you process the intent and extract the speech text from the intent.
@Override
protected void onActivityResult(int requestCode, int …

I've been trying to get my Spring web application to work with Keycloak without any luck for days now. I followed the instructions mentioned in their documentation here.

I have setup a Keycloak server running in Wildfly 9. For my web application, I'm using JBoss AS 7 with Spring Framework 4.1.7. I have configured the adapter for my JBoss AS 7 following the steps here. Then for my Spring web application I followed the steps mentioned here. …

我正在创建一个使用服务器存储数据的移动应用程序.我也在创建Web应用程序,它将作为我的移动应用程序的restful数据库服务.

我计划使用Keycloak进行移动设备的用户管理和身份验证(Oauth2).我知道Keycloak有一个用户注册的端点,但它要求移动应用程序重定向到keycloak服务器URL.如果可能的话,我想避免这种情况,并在移动应用程序中完成所有过程.此外,我不知道其他端点,如密码重置和忘记密码.有人知道吗？

我使用 Spring-Boot 和 Spring Security OAuth2 开发了一个简单的 web 应用程序，我想只允许从客户端应用程序访问所有资源。有些资源需要客户端进行身份验证，而有些则不需要。

我有以下配置：

@Configuration
@EnableResourceServer
protected static class ResourceServerConfig extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.requestMatchers()
            .and()
            .authorizeRequests()
            .antMatchers("/account/**").permitAll()
            .antMatchers("/user/**").access("#oauth2.hasScope('read')")
            .antMatchers("/transaction/**").access("#oauth2.hasScope('read')");
    }

}

@Configuration
@EnableAuthorizationServer
protected static class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        endpoints.authenticationManager(authenticationManager);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
            .withClient("my-trusted-client")
            .authorizedGrantTypes("authorization_code", "password", "refresh_token")
            .authorities("ROLE_CLIENT", "ROLE_TRUSTED_CLIENT")
            .scopes("read", "write", "trust")
            .accessTokenValiditySeconds(3600);
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer …

我正在尝试在单个片段中创建Master/Detail事务.我想过使用LinearLayout作为我的头文件编辑文本的容器.然后是RecyclerView以获取详细信息.

如何实现LinearLayout的折叠/扩展,类似于CollapsingToolbar效果？

这是我正在尝试做的截图.

到目前为止我的xml代码.

如何在PreferenceFragment中添加进度条？我有一些异步任务正在运行,它将在完成时显示我的偏好中的一些值.因此,在进行后台处理时,我计划在中心只显示一个进度条.任务完成后,我计划显示我的所有偏好.

这是我到目前为止所拥有的.

PreferenceFragment

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.pref_account);
    }

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    new AsyncTask<Void,Void,Void>() {

        String firstName, lastName, email;
        @Override
        protected void doInBackground() {
            // Doing something here to fetch values
        }

        @Override
        protected void onPostExecute() {
            findPreference("first_name").setSummary(firstName);
            findPreference("last_name").setSummary(lastName);
            findPreference("email").setSummary(email);
        }
    }
}

pref_account.xml

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">

    <Preference android:key="first_name"
        android:title="@string/prompt_first_name"
        android:summary="" />

    <Preference android:key="last_name"
        android:title="@string/prompt_last_name"
        android:summary="" />

    <Preference android:key="email"
        android:title="@string/prompt_email"
        android:summary=""
        android:inputType="textEmailAddress" />

    <Preference android:key="sign_out"
        android:title="@string/action_sign_out" />

</PreferenceScreen>

我的问题是,因为这是一个PreferenceFragment并且我没有覆盖onCreateView的方法,我应该在哪里以及如何添加进度条？
