java-在Retrofit调用后更改折叠的工具栏标题

我正在尝试基于Retrofit2响应来修改工具栏标题,但是没有变化.

getSupportActionbar().setTitle("here work");final Call<Process> getProcess = WiimAPI.getService(serverAddress).getProcess(ID);getProcess.enqueue(new Callback<Process>() {    @OverrIDe    public voID onResponse(Call<Process> call, Response<Process> response) {        mProcess = response.body();        getSupportActionbar().setTitle(mProcess.getname()); // this not work    }    @OverrIDe    public voID onFailure(Call<Process> call, Throwable t) {        // ...     }});

mProcess.getname()是JsON文件中的字符串.我也用硬编码的字符串进行了测试(防止mProcess.getname()错误的值),但是没有效果.
通话之前就像魅力一样.

收到回调后,有什么方法可以更新工具栏标题？

更新资料

谢谢您的帮助.现在,我发现了真正的问题：折叠工具栏.
我做了一个空白的应用程序来复制错误,并且代码可以正常工作,但是当我使用折叠工具栏运行相同的代码时……Bingo！完整的代码如下：

MainActivity.java：

package com.example.retrofitTitle;import androID.os.Bundle;import androID.support.v7.app.AppCompatActivity;import androID.support.v7.Widget.Toolbar;import androID.vIEw.Menu;import androID.vIEw.MenuItem;import androID.Widget.TextVIEw;import retrofit2.Call;import retrofit2.Callback;import retrofit2.Response;public class MainActivity extends AppCompatActivity {    @OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.activity_main);        Toolbar toolbar = (Toolbar) findVIEwByID(R.ID.toolbar);        setSupportActionbar(toolbar);        getData();    }    @OverrIDe    public boolean onCreateOptionsMenu(Menu menu) {        getMenuInflater().inflate(R.menu.menu_main, menu);        return true;    }    @OverrIDe    public boolean onoptionsItemSelected(MenuItem item) {        int ID = item.getItemID();        if (ID == R.ID.action_settings) {            return true;        }        return super.onoptionsItemSelected(item);    }    public voID getData() {        getSupportActionbar().setTitle("Here work ...");        // https://raw.githubusercontent.com/LearnWebCode/Json-example/master/        final Call<Pet> getPet = MyAPI.getService("https://raw.githubusercontent.com/LearnWebCode/Json-example/master/").getPet();        getPet.enqueue(new Callback<Pet>() {            @OverrIDe            public voID onResponse(Call<Pet> call, Response<Pet> response) {                Pet pet = response.body();                getSupportActionbar().setTitle(pet.getname()); // Here not work                TextVIEw text = findVIEwByID(R.ID.log);                text.setText("Done");            }            @OverrIDe            public voID onFailure(Call<Pet> call, Throwable t) {                getSupportActionbar().setTitle("Failure Title");            }        });    }}

MyAPI.java

package com.example.retrofitTitle;import retrofit2.Call;import retrofit2.converter.gson.GsonConverterFactory;import retrofit2.http.GET;public class MyAPI {    public interface APIService {        @GET("pet-of-the-day.Json")        Call<Pet> getPet();    }    public static APIService getService(String url) {        retrofit2.Retrofit retrofit = new retrofit2.Retrofit.Builder()                .baseUrl(url)                .addConverterFactory(GsonConverterFactory.create())                .build();        return retrofit.create(APIService.class);    }}

package com.example.retrofitTitle;public class Pet {    private String name;    private String specIEs;    private Integer age;    private String photo;    public String getname() {        return name;    }    public voID setname(String name) {        this.name = name;    }    public String getSpecIEs() {        return specIEs;    }    public voID setSpecIEs(String specIEs) {        this.specIEs = specIEs;    }    public Integer getAge() {        return age;    }    public voID setAge(Integer age) {        this.age = age;    }    public String getPhoto() {        return photo;    }    public voID setPhoto(String photo) {        this.photo = photo;    }}

解

发现真正的问题后,我在这里搜索并找到了解决方案：
https://github.com/henrytao-me/smooth-app-bar-layout/issues/32

设置CollapsingToolbarLayout小部件ID(collapsing_toolbar)和活动代码：

CollapsingToolbarLayout mCollapsingToolbarLayout = findVIEwByID(R.ID.collapsing_toolbar);mCollapsingToolbarLayout.setTitle(pet.getname());

现在名称已更改：D

解决方法:

我已经尝试过getSupportActionbar().setTitle(“ hello”);内部翻新回调它对我来说很好.

您的问题是每次调用onFailure时都要进行改造.因此,不会调用getSupportActionbar().setTitle(“ hello”).

也可以在onFailure中尝试getSupportActionbar().setTitle(“ hello”).
