android - 如何恢复和存储两个字符串值？

Question

我有两个值，如何存储和恢复它。

public void SetCaseInfo(String PatientType, String Teethsselected) { // All objects are from android.context.Context
    SharedPreferences settings = getSharedPreferences(DEALSPOTR_PREFS, 0);
    SharedPreferences.Editor editor = settings.edit();
    editor.putString(PatientType, Teethsselected);
    editor.commit();
}

public String getCaseInfo() {
    SharedPreferences settings = getSharedPreferences(DEALSPOTR_PREFS, 0);
    String value = settings.getString(PatientType, Teethsselected);
    return value;
}

正确吗？

Answer 1

在您的代码中，PatientType 不得更改，以便您能够检索 Teethsselected

您没有保存 2 个字符串

public void SetCaseInfo(String PatientType, String Teethsselected) { // All objects are from android.context.Context
    SharedPreferences settings = getSharedPreferences(DEALSPOTR_PREFS, 0);
    SharedPreferences.Editor editor = settings.edit();
    editor.putString("teeth", Teethsselected);
    editor.putString("patient", PatientType);
    editor.commit();
}

public String getTeethsselected() {
    SharedPreferences settings = getSharedPreferences(DEALSPOTR_PREFS, 0);
    String value = settings.getString("teeth", "default");
    return value;
}

public String getPatientType() {
    SharedPreferences settings = getSharedPreferences(DEALSPOTR_PREFS, 0);
    String value = settings.getString("patient", "default");
    return value;
}
