寫代碼前要先加上權限和依賴：
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.INTERNET" />依賴：
compile 'com.android.support:design:26.+' compile 'com.google.code.gson:gson:2.8.2' compile 'com.xhb:xbanner:1.2.9' compile 'com.github.bumptech.glide:glide:3.6.0' compile 'com.squareup.okhttp3:okhttp:3.6.0' compile 'com.squareup.okio:okio:1.11.0' compile 'com.android.support:recyclerview-v7:26.+'
各種工具類：
可能用到的接口：
//創建訂單 public static final String CHUANGJIAN_API = "https://www.zhaoapi.cn/product/createOrder"; //訂單列表 public static final String DINGDAN_API = "https://www.zhaoapi.cn/product/getOrders?uid=2845"; //修改訂單 public static final String UpDateDingDan_API = "https://www.zhaoapi.cn/product/updateOrder?uid=2845";一個比較實用的工具類 ： CommonUtils
/** * 一些操作的工具類 */ public class CommonUtils { private static SharedPreferences sharedPreferences; /** * DashApplication.getAppContext()可以使用,但是會使用系統默認的主題樣式，如果你自定義了某些樣式可能不會被使用 * @param layoutId * @return */ public static View inflate(int layoutId) { View view = View.inflate(MyApplication.getAppContext(), layoutId, null); return view; } /** * 自己寫的運行在主線程的方法 * 如果是主線程,執行任務,否則使用handler發送到主線程中去執行 * * * @param runable */ public static void runOnUIThread(Runnable runable) { //先判斷當前屬於子線程還是主線程 if (android.os.Process.myTid() == MyApplication.getMainThreadId()) { runable.run(); } else { //子線程 MyApplication.getAppHanler().post(runable); } } }MyApplicaion:
/** * Created by Administrator */ public class MyApplication extends Application { private static Context context; private static Handler handler; private static int mainId; public static boolean isLoginSuccess;//是否已經登錄的狀態 @Override public void onCreate() { super.onCreate(); //關於context----http://blog.csdn.net/lmj623565791/article/details/40481055 context = getApplicationContext(); //初始化handler handler = new Handler(); //主線程的id mainId = Process.myTid(); } /** * 一下三個訂單用 */ /** * 對外提供了context * @return */ public static Context getAppContext() { return context; } /** * 得到全局的handler * @return */ public static Handler getAppHanler() { return handler; } /** * 獲取主線程id * @return */ public static int getMainThreadId() { return mainId; } }寫完之後別忘了再清單列表中配置：
訂單的Activity：
先佈局

主頁面
public class DingDanActivity extends AppCompatActivity implements View.OnClickListener { private PopupWindow popupMenu; private ImageView imageView; private List<String> list; private Button daifukuan; private Button yiwancheng; private Button yiquxiao; private FrameLayout frameLayout; private DingDanFragment fragment; private String[] strings; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_ding_dan); findView(); list = new ArrayList<>(); list.add("待付款"); list.add("已完成"); list.add("已取消"); strings = new String[]{"待付款","已完成","已取消"}; //圖片的點擊事件 imageView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { showPopWindow(); } }); fragment = new DingDanFragment(); getSupportFragmentManager().beginTransaction().replace(R.id.frameLayout,fragment).commit(); } private void findView() { imageView = findViewById(R.id.image); daifukuan = findViewById(R.id.btn_daifukuan); yiwancheng = findViewById(R.id.btn_yiwancheng); yiquxiao = findViewById(R.id.btn_yiquxiao); frameLayout = findViewById(R.id.frameLayout); } //popwindow顯示 private void showPopWindow() { //設置contentView View contentView = LayoutInflater.from(DingDanActivity.this).inflate(R.layout.popwindow_item, null); popupMenu = new PopupWindow(contentView); popupMenu.setWidth(ViewGroup.LayoutParams.WRAP_CONTENT); popupMenu.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT); //設置各個控件的點擊響應 TextView tv1 = contentView.findViewById(R.id.pop_dai); TextView tv2 = contentView.findViewById(R.id.pop_wancheng); TextView tv3 = contentView.findViewById(R.id.pop_quxiao); tv1.setOnClickListener(this); tv2.setOnClickListener(this); tv3.setOnClickListener(this); popupMenu.showAsDropDown(imageView); } /** * 點擊popwindow裏的內容 * @param v */ @Override public void onClick(View v) { switch (v.getId()){ case R.id.btn_daifukuan: getSupportFragmentManager().beginTransaction().replace(R.id.frameLayout,fragment).commit(); break; case R.id.btn_yiwancheng: getSupportFragmentManager().beginTransaction().replace(R.id.frameLayout,fragment).commit(); break; case R.id.btn_yiquxiao: getSupportFragmentManager().beginTransaction().replace(R.id.frameLayout,fragment).commit(); break; case R.id.pop_dai: popupMenu.dismiss(); break; case R.id.pop_wancheng: popupMenu.dismiss(); break; case R.id.pop_quxiao: popupMenu.dismiss(); break; default: break; } } }
因爲訂單裏把數據放在放入framlayout中替換，所有就把數據寫到fragment中，
fragment佈局
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:orientation="horizontal" android:layout_height="match_parent"> <ListView android:id="@+id/listView" android:layout_width="match_parent" android:layout_height="wrap_content"></ListView> </LinearLayout>
放訂單數據的fragment
public class DingDanFragment extends Fragment { private View view; private List<DingDanBean.DataBean> dingdanList; private ListView listView; private DingDanBean dingDanBean; private DingDanAdapter adapter; Handler handler = new Handler() { @Override public void handleMessage(Message msg) { if (msg.what == 1) { if (dingdanList.size() > 0) { setAdapter(); add(); } else { Toast.makeText(getActivity(), "沒有此類型的商品訂單哦", Toast.LENGTH_SHORT).show(); } } else if (msg.what == 2) { add(); setAdapter(); } } }; @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { view = View.inflate(getActivity(), R.layout.dingdan_layout, null); listView = view.findViewById(R.id.listView); return view; } @Override public void onActivityCreated(@Nullable Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); //拿到傳過來的值 add(); } private void add() { OkHttp3Util.doGet(Api.DINGDAN_API, new Callback() { @Override public void onFailure(Call call, IOException e) { } @Override public void onResponse(Call call, Response response) throws IOException { if (response.isSuccessful()) { final String string = response.body().string(); CommonUtils.runOnUIThread(new Runnable() { @Override public void run() { dingDanBean = new Gson().fromJson(string, DingDanBean.class); dingdanList = dingDanBean.getData(); dingdanList.addAll(dingDanBean.getData()); Log.i("------dal", dingdanList.toString()); handler.sendEmptyMessage(1); } }); } } }); } //設置適配器 private void setAdapter() { if (adapter == null) { adapter = new DingDanAdapter(getActivity(), dingdanList, handler); listView.setAdapter(adapter); } else { adapter.notifyDataSetChanged(); } } }適配器的佈局：
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <LinearLayout android:paddingLeft="35dp" android:orientation="vertical" android:layout_width="0dp" android:layout_weight="3" android:layout_height="wrap_content"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="2dp" android:textColor="#000" android:id="@+id/dingtitile" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="3dp" android:id="@+id/dingprice" android:textColor="#f00" android:textSize="20dp" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="3dp" android:id="@+id/dingtime" /> </LinearLayout> <LinearLayout android:orientation="vertical" android:layout_width="0dp" android:layout_weight="1" android:layout_height="wrap_content"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/zhuangtai" android:layout_marginLeft="10dp" android:text="yi" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="訂單" android:id="@+id/dan" /> </LinearLayout> </LinearLayout>
訂單適配器：
