和风天气SDK

和风天气官方

集成过程

原理

• 集成和风天气
• 添加依赖
• 添加权限
• 在主线程进行动态权限申请
• 定义getWeather()方法

方法

    //获取天气
    public void getWeather() {
        HeWeather.getWeatherNow(getActivity(), Lang.CHINESE_SIMPLIFIED, Unit.METRIC, new HeWeather.OnResultWeatherNowBeanListener() {

每日诗词推荐

Okhttp

Gson

ListView

原理

• 通过Okhttp从后台获取gson数据
• 执行主线程
• 在主线程中初始化ListView
  listView.setAdapter(myAdapter);

主线程执行

getActivity().runOnUiThread(new Runnable() {
      @Override
      public void run() {
            action();
      }
});

诗词点击跳转

Click

Intent

点击事件

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override      
      public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
      Intent intent = new Intent(getActivity(), PoemDetail.class);
      intent.putExtra("poem", rec.get(position));
      startActivity(intent);
      }
});

动态权限申请

Android权限

权限申请

//定义boolean类型的权限申请结果变量
private boolean permission;
private PackageManager pm;

//在主线程中进行权限申请
pm = getActivity().getPackageManager();
permission = (
      PackageManager.PERMISSION_GRANTED ==pm.checkPermission("android.permission.ACCESS_FINE_LOCATION", 
      "com.example.a15632.poetrydemo"));

//权限申请回调
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
      super.onRequestPermissionsResult(requestCode, permissions, grantResults);
      if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            Toast.makeText(getActivity(), "Permission GET", Toast.LENGTH_SHORT).show();
            Log.e("permission1",permission+"");
            getWeather();
      } else {
//Permission Denied
            Toast.makeText(getActivity(), "Permission Denied", Toast.LENGTH_SHORT).show();
            Log.e("permission1",permission+"");
      }
}

查找功能实现

Okhttp

Gson

ListView

UI键盘搜索

android:imeOptions属性:

• actionGo 开始
• actionSend 发送
• actionSearch 搜索
• actionDone 完成

<EditText
    android:id="@+id/et_home_input"
    android:hint="搜索诗句、诗名、关键词"
    android:imeOptions="actionSearch"
    android:inputType="text"
    android:background="@null"
    android:layout_width="0dp"
    android:layout_height="40dp"
    android:layout_weight="5"/>

        //关于EditView的操作,相应虚拟键盘上的"搜索"按钮
        input.setOnEditorActionListener(new TextView.OnEditorActionListener() {
            @Override
            public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                search(v);
                return true;
            }
        });

短信验证码服务SMSSDK

MobTech

集成过程

原理

• 集成SMSDK
• 用户同意
• 从短信自动获取
• 注册一个事件回调监听，用于处理SMSSDK接口请求的结果
• 自定义EventHandler，并通过Handler返回主线程
• 使用SMSSDK获取验证码
• 注销EventHandler

集成、使用代码

1. 集成

// 在MobSDK的扩展中注册SMSSDK的相关信息
MobSDK {
    appKey "2d0f808219f71"
    appSecret "3fbace76120dd6d8b1027a591ef49002"
    SMSSDK { "autoSMS true" }

}

保持登录状态

SharedPreferences

原理

• 使用SharedPreferences记录用户的信息
• SharedPreferences通过键值对的形式存储
• 当用户访问自身信息，自动查找SharedPreferences生成的程序内部文件中的信息
