Android SharedPreferences工具类

融合了工具类和枚举，话不多说，直接上代码：

public enum SPCode {

    USERNAME("username","未登录","用户名"),
    IS_LOGIN("isLogin",false,"是否登陆");

    SPCode(String key, String defaultValue, String description) {
        this.KEY = key;
        this.DEF_String = defaultValue;
        this.DES = description;
    }
    SPCode(String key, int defaultValue, String description) {
        this.KEY = key;
        this.DEF_int = defaultValue;
        this.DES = description;
    }
    SPCode(String key, float defaultValue, String description) {
        this.KEY = key;
        this.DEF_float = defaultValue;
        this.DES = description;
    }
    SPCode(String key, long defaultValue, String description) {
        this.KEY = key;
        this.DEF_long = defaultValue;
        this.DES = description;
    }
    SPCode(String key, boolean defaultValue, String description) {
        this.KEY = key;
        this.DEF_boolean = defaultValue;
        this.DES = description;
    }

    private String KEY;
    private String DEF_String;
    private int DEF_int;
    private float DEF_float;
    private long DEF_long;
    private boolean DEF_boolean;
    private String DES;

    public String GET_String(){
        return SPUtils.get(KEY,DEF_String);
    }
    public int GET_Int(){
        return SPUtils.get(KEY,DEF_int);
    }
    public float GET_Float(){
        return SPUtils.get(KEY,DEF_float);
    }
    public long GET_Long(){
        return SPUtils.get(KEY,DEF_long);
    }
    public boolean GET_Boolean(){
        return SPUtils.get(KEY,DEF_boolean);
    }

    public void SAVE(String value){
        SPUtils.put(KEY,value);
    }
    public void SAVE(int value){
        SPUtils.put(KEY,value);
    }
    public void SAVE(float value){
        SPUtils.put(KEY,value);
    }
    public void SAVE(long value){
        SPUtils.put(KEY,value);
    }
    public void SAVE(boolean value){
        SPUtils.put(KEY,value);
    }

    public String KEY(){
        return KEY;
    }

    public String DES(){
        return DES;
    }

}

储存值得时候：

  SPCode.USERNAME.SAVE(username);
  SPCode.IS_LOGIN.SAVE(true);

取值的时候：

    SPCode.USERNAME.GET_String();
    SPCode.IS_LOGIN.GET_Boolean()
    

 

 

还能继续简化，看自己需要了；
