【Android项目实战 | 从零开始写app(14)】实现用户中心模块清除token退出登录 & 信息修改等功能
本文共 35134 字，大约阅读时间需要 117 分钟。
五一后，被ji金伤了，哇呜呜，还是得苦逼老老实实打工写代码，看下面吧
本篇实现效果：
实现登录用户名展示到用户中心页面上，并且页面有个人信息，订单列表，修改密码，意见反馈发送到服务端，前面登录后，通过SharedPreferences把token值保存到本地，退出登录时，用editor.clear()直接清除保存的koten，跳转到登录界面。本篇用的技术同样是gson+okhttp，老生常谈了，写过那么多遍，因该都懂了，哈哈~，我就当这样默认了。

在前面的基础上，继续完善项目，没有的请看前面系列文章
UserFragment：
在UserFragment中加入下面代码：

用户中心页面布局，一些文本text，color等资源应该放到style目录下，方便后期维护修改，比较统一，但我没有这样做，就直接这样写了，你们可以自己实现，不清楚的看我前面文章：
AdviseActivity：

- json : application/json
- xml : application/xml
- png : image/png
- jpg : image/jpeg

这里用Handler 处理异步消息处理，它的主要作用：消息处理者，主要用于发送跟处理消息，发送消息:SendMessage()，处理消息: HandleMessage()
子线程中更新主线程的UI。 Handler是android线程之间的消息机制，主要的作用是将一个任务切换到指定的线程中去执行，（准确的说是切换到构成handler的looper所在的线程中去出处理）android系统中的一个例子就是主线程中的所有操作都是通过主线程中的handler去处理的。
上面的msg.what=1中的what是自定义的一个Message的识别码，以便于在Handler的handleMessage方法中根据what识别出不同的Message，以便我们做出不同的处理操作。通过给obj赋值Object类型传递向Message传入请求到的数据。

公共实体类
在bean目录下新家LoginBean.class 实体类，gson解析json数据会用到
LoginBean：
public class LoginBean { /** * msg : 操作成功 * code : 200 * token : eyJhbGciOiJIUzUxMiJ9.eyJsb2dpbl91c2VyX2tleSI6ImMyYjE1YTNkLTlkNWQtNGFmZi04MGU3LTNlNWMxYTdkYzcyNSJ9.sZxcMsSvH7F50jCpTdtrv296mgq5IOI8OAo8rAXDQ4mw7KssvPsdwFcFdxHyGodfYmrsDxv0wyyEgDdl7JDxoQ */ private String msg; private String code; private String token; public String getMsg() { return msg; } public void setMsg(String msg) { this.msg = msg; } public String getCode() { return code; } public void setCode(String code) { this.code = code; } public String getToken() { return token; } public void setToken(String token) { this.token = token; } public LoginBean(String msg, String code, String token) { this.msg = msg; this.code = code; this.token = token; } @Override public String toString() { return "UserLogin{" + "msg='" + msg + '\'' + ", code=" + code + ", token='" + token + '\'' + '}'; }} 个人订单
OrderActivity：
个人订单跟解析新闻数据差不多，不过个人订单属于个人隐私的数据，在请求服务端数据时，需要在okhttp中的addHeader("Authorization",token)请求头带上Authorization 标识的token值来验证请求。
public class OrderActivity extends AppCompatActivity { private Toolbar toolbar; private ListView order_listView; private OrderBean orderBean;/* private Handler handler = new Handler(){ @Override public void handleMessage(@NonNull Message msg) { super.handleMessage(msg); if (msg.what==1) { String result = msg.obj.toString(); Gson gson = new Gson(); orderBean = gson.fromJson(result,OrderBean.class); OrderAdapter orderAdapter = new OrderAdapter(); order_listView.setAdapter(orderAdapter); order_listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView adapterView, View view, int i, long l) { Toast.makeText(getApplication(),"你点击了："+i,Toast.LENGTH_LONG).show(); } }); } } };*/ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_order); toolbar = findViewById(R.id.toolbar); order_listView = findViewById(R.id.order_listView); getHttp(); } private void getHttp() { // 请求参数 int pageNum = 1; int pageSize = 10; int userId = 1; 实例化 OkHttpClient 对象 OkHttpClient client = new OkHttpClient(); // 读取本地保存的token 值 SharedPreferences sp = getSharedPreferences("token_data",MODE_PRIVATE); String token =sp.getString("token",""); // 创建JSONObject 对象 JSONObject object = new JSONObject(); try { // 带上请求体参数 object.put("pageNum",1); object.put("pageSize",10); object.put("userId",1); } catch (JSONException e) { e.printStackTrace(); } // 设置 MediaType参数 MediaType mediaType = MediaType.parse("application/json;charset=utf-8"); // 请求体 RequestBody requestBody = RequestBody.create(mediaType,object.toString()); String url = APIConfig.BASE_URL+"/userinfo/orders/list"+"?"+pageNum+"&"+pageSize+"&"+userId; Request request = new Request.Builder() .url(url) .addHeader("Authorization",token) .build(); // 请求回调 Call call = client.newCall(request); // 重写异步请求 call.enqueue(new Callback() { @Override public void onFailure(Call call, IOException e) { Log.i("onFailure",e.getMessage()); } // 请求响应成功 @Override public void onResponse(Call call, Response response) throws IOException { if (response.isSuccessful()) { String result = response.body().string(); Log.i("请求成功",result); runOnUiThread(new Runnable() { @Override public void run() { // gson解析请求到的数据 Gson gson = new Gson(); orderBean = gson.fromJson(result,OrderBean.class); OrderAdapter orderAdapter = new OrderAdapter(); order_listView.setAdapter(orderAdapter); order_listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView adapterView, View view, int i, long l) { Toast.makeText(getApplication(),"你点击了"+i,Toast.LENGTH_LONG).show(); } }); } }); } } }); } @Override protected void onStart() { super.onStart(); // 顶部标题栏 toolbar.setTitle("订单列表"); setSupportActionBar(toolbar); // 设置标题栏图标 toolbar.setNavigationIcon(R.mipmap.top_bar_left_back); toolbar.setTitleMarginEnd(200); // 点击事件 toolbar.setNavigationOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { finish(); } }); } public class OrderAdapter extends BaseAdapter { // item 数据 @Override public int getCount() { return orderBean.getData().size(); } @Override public Object getItem(int i) { return orderBean.getData().get(i); } @Override public long getItemId(int i) { return i; } // 每项item布局 @Override public View getView(int i, View view, ViewGroup viewGroup) { HolderView holderView; if (view==null) { view = View.inflate(getApplicationContext(),R.layout.order_item,null); holderView = new HolderView(); holderView.tv_ordernum = view.findViewById(R.id.tv_ordernum); holderView.order_date = view.findViewById(R.id.order_date); holderView.order_type = view.findViewById(R.id.order_type); view.setTag(holderView); } else { holderView = (HolderView) view.getTag(); } holderView.order_date.setText(orderBean.getData().get(i).getCreateTime()); holderView.tv_ordernum.setText(orderBean.getData().get(i).getOrderNum()); holderView.order_type.setText("地铁"); return view; } // 优化ListView class HolderView{ TextView tv_ordernum; TextView order_date; TextView order_type; } }} 基本都注释了，我们都知道在Android中不能在主线程进行网络请求等耗时操作，而且Ui控件的更新不能在工作线程中操作，所以通过 runOnUiThread这个方法来更新UI界面。当然跟新Ui还有其他方式例如：使用AsyncTask、Handler等，这里不做深究。如果在fragment中，记得通过getActivity获取当前
