在类定义中:

private static final String PREFERENCES = "shared_prefs";

private static final SharedPreferences sharedPreferences  = getApplicationContext().getSharedPreferences(PREFERENCES, MODE_PRIVATE);

类内部:

public static void deleteAllSharedPrefs(){
    sharedPreferences.edit().clear().commit();
}

我的解决方案:

SharedPreferences preferences = getSharedPreferences("Mypref", 0);
preferences.edit().remove("text").commit();

在类定义中:

private static final String PREFERENCES = "shared_prefs";

private static final SharedPreferences sharedPreferences  = getApplicationContext().getSharedPreferences(PREFERENCES, MODE_PRIVATE);

类内部:

public static void deleteAllSharedPrefs(){
    sharedPreferences.edit().clear().commit();
}

芬兰湾的科特林:

  var prefs2: SharedPreferences? = context!!.getSharedPreferences("loginFB", 0)
  prefs2!!.edit().remove("email").commit()

试试下面的代码:

SharedPreferences sharedPreferences = getSharedPreferences("fake", Context.MODE_PRIVATE);
SharedPreferences.Editor edit = sharedPreferences.edit();
edit.clear().commit();

要删除一个特定的值，

SharedPreferences。编辑器删除(字符串键)后跟commit()或apply()

要删除所有值， SharedPreferences。编辑器clear()后面跟着commit()或apply()
