试试这个
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
aint
值，这会导致您的问题问题就在这里startWeight.setText（sweighint1）
，这里是startWeight.setText（cWeightInt1）和这里的startWeight.setText（gWeightInt1）使用这个startWeight.setText（String.valueOf（sweighint1））
和startWeight.setText（String.valueOf（cWeightInt1））
和startWeight.setText（String.valueOf（gWeightInt1））您正在使用的EditText.setText方法需要一个资源id。因此，例如，您可以执行myText.setText（R.string.app_name）。要解决您的问题，请对要设置int值的所有编辑文本执行以下操作：startWeight.setText（Integer.toString（sweighint1））；希望有帮助！谢谢大家的帮助！我失去了我的java图书租赁，因为学期结束了，我瞎了眼，再次感谢你！谢谢你这么多，因为这工作！
