删除所有首选项:

SharedPreferences settings = context.getSharedPreferences("PreferencesName", Context.MODE_PRIVATE);
settings.edit().clear().commit();

去除单一偏好:

SharedPreferences settings = context.getSharedPreferences("PreferencesName", Context.MODE_PRIVATE);
settings.edit().remove("KeyName").commit();

清除它们:

PreferenceManager.getDefaultSharedPreferences(context).edit().clear().apply()

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()

删除所有首选项:

SharedPreferences settings = context.getSharedPreferences("PreferencesName", Context.MODE_PRIVATE);
settings.edit().clear().commit();

去除单一偏好:

SharedPreferences settings = context.getSharedPreferences("PreferencesName", Context.MODE_PRIVATE);
settings.edit().remove("KeyName").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();
}
