Save Edittext and Datepicker in Shared Preferences

Question

I’m trying to save an edittext and a datepicker but they save both with a dice of the two. The date Picker when clicking Editext2 it opens the calendar where you click and it selects the date for edittext2.

I just need to know how to save them both by clicking the Activity button.

basically i want to save the oil mileage in edittext1, and the date that was made in edittext2. the boot will save for me!

Try The Next:

//SALVA OS DADOS:
    //TAG: é o ID para resgatar o valor
    //VALUE: o valor a ser armazenado
    private void makeTag(final String tag, final String value){
        SharedPreferences.Editor preferencesEditor = savednotes.edit();
        /// passamos a TAG, a qual vamos usar para resgatar
        preferencesEditor.putString(tag, value);
        preferencesEditor.commit();
    }
//RESGATA OS DADOS
    //TAG: é o ID para resgatar o valor
    private void getTag(final String tag){
        String value = savednotes.getString(tag, null);
        return value;
    }

To make it easier, I suggest you create cosntantes with the name of the tags:

public final String edittext1TAG = "TAG1";
public final String edittext2TAG = "TAG2";

When you save :

makeTag(edittext1TAG, editTextOleo.getText().toString());
