缺少字符串资源ID

时间：2018-12-19 08:31:52

标签： java android

大家好，我希望有人能指出为什么我有一个特定的错误。我的程序告诉我，我缺少一个字符串资源ID，但是，至少在我所知的范围内，我没有删除任何字符串，也不需要添加任何字符串。我仍然是一个初学者程序员，我还不太清楚哪里出了问题。在我添加了sharedpreferences类以保存和加载来自editTexts的数据之前，我所能说的一切都已适当放置并开始了活动。 （这还不是我们要做的事情，但我正在尝试将数据保存并加载到editText中。）

我需要一个用户能够减轻重量并在打开activity时重新加载该数据。谢谢高级的人！

我的错误：

尝试

int sWeightInt1 = prefs.getInt("sWeightInt", 0);
    startWeight.setText(String.valueOf(WeightInt1));

    int cWeightInt1 = prefs.getInt("cWeightInt", 0);
    startWeight.setText(String.valueOf(cWeightInt1));

    int gWeightInt1 = prefs.getInt("gWeightInt", 0);
    startWeight.setText(String.valueOf(gWeightInt1));

您不能setText一个int的值，这会导致您的问题
