1. 字符串处理

   1.字符串分割：split(); 结合正则效果极佳
   2.正则表达式
   3. 字符串截取 indexof()
   4. 字符串判断 contains()
   5. 字符串替换 replace(), replaceAll,结合正则
   6. 字符串换颜色 SpannableStringBuilder

2. 常用的布局

   1.LRecyclerView ①下拉刷新，上滑加载②设置空页面

   public abstract class ListBaseAdapter extends RecyclerView.Adapter {
   protected Context mContext;
   private LayoutInflater mInflater;
   
   protected List mDataList = new ArrayList<>();
   
   public ListBaseAdapter(Context context) {
       mContext = context;
       mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
   }
   
   @Override
   public SuperViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
       View itemView = mInflater.inflate(getLayoutId(), parent, false);
       return new SuperViewHolder(itemView);
   }
   
   @Override
   public void onBindViewHolder(SuperViewHolder holder, int position) {
       onBindItemHolder(holder, position);
   }
   
   //局部刷新关键：带payload的这个onBindViewHolder方法必须实现
   @Override
   public void onBindViewHolder(SuperViewHolder holder, int position, List
