各种数据类型的put和get都已经实现,且实现了缓存的clear和remove方法。
直接上码:
public class SharePreferenceUtil {
private static final String TAG = SharePreferenceUtil.class.getSimpleName();
private static final String DEFAULT_SHARE_NAME = "biliparser";
private static SharedPreferences sharedPreferences;
public static void init(Context context){
sharedPreferences = context.getSharedPreferences(DEFAULT_SHARE_NAME,Context.MODE_PRIVATE);
}
public static void put(String key,String value){
sharedPreferences.edit().putString(key,value).apply();
}
public static String get(String key){
return sharedPreferences.getString(key,"");
}
public static String getString(String key,String defaultValue){
return sharedPreferences.getString(key,defaultValue);
}
public static void put(String key,int value){
sharedPreferences.edit().putInt(key,value).apply();
}
public static int getInt(String key){
return sharedPreferences.getInt(key,0);
}
public static int getInt(String key,int defaultValue){
return sharedPreferences.getInt(key,defaultValue);
}
public static void put(String key,Long value){
sharedPreferences.edit().putLong(key,value).apply();
}
public static Long getLong(String key){
return sharedPreferences.getLong(key,0);
}
public static Long getLong(String key,Long defaultValue){
return sharedPreferences.getLong(key,defaultValue);
}
public static void put(String key,boolean value){
sharedPreferences.edit().putBoolean(key,value).apply();
}
public static boolean getBoolean(String key){
return sharedPreferences.getBoolean(key,false);
}
public static boolean getBoolean(String key,boolean defaultValue){
return sharedPreferences.getBoolean(key,defaultValue);
}
public static void put(String key,float value){
sharedPreferences.edit().putFloat(key,value).apply();
}
public static float getFloat(String key){
return sharedPreferences.getFloat(key,0);
}
public static float getFloat(String key,float defaultValue){
return sharedPreferences.getFloat(key,defaultValue);
}
public static boolean contains(String key){
return sharedPreferences.contains(key);
}
public static void remove(String key){
sharedPreferences.edit().remove(key).apply();
}
public static void clear(){
sharedPreferences.edit().clear().apply();
}
}
移植到项目中导入相关包即可使用,缓存名字可以自己改,我这里用的是biliparser。
使用前先调用init方法,建议在Application类中调用。
