Preference settings in Android studio how to connect the value in EditTextPreference to a TextView

Question

I don't know how to find the value from the EditTextPreference. Like when i write a number in Edittextpreference I want the number shows up in my Textview "numTxt" in my fragment firstlayout xml :(.

Blockquote The base for the settings menu is the "Settings Activity" where you get in Android studio, new>Activity>Settings Activity.so in the xml pref_general.xml is where the EditTextPreference is.

Please look at the imgur photos where the textfield is going to be edited. Image-imgur

This is the preference xml file.

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">

    <SwitchPreference
        android:defaultValue="true"
        android:key="example_switch"
        android:summary="@string/pref_description_social_recommendations"
        android:title="@string/pref_title_social_recommendations" />

    <!-- NOTE: EditTextPreference accepts EditText attributes. -->
    <!-- NOTE: EditTextPreference's summary should be set to its value by the activity code. -->




    <EditTextPreference
        android:capitalize="words"
        android:defaultValue="@string/pref_default_display_name"
        android:inputType="textCapWords"
        android:key="example_text"
        android:id="@+id/textnrisettings"
        android:maxLines="1"
        android:selectAllOnFocus="true"
        android:singleLine="true"
        android:title="@string/pref_title_display_name" />

    <!-- NOTE: Hide buttons to simplify the UI. Users can touch outside the dialog to
         dismiss it. -->
    <!-- NOTE: ListPreference's summary should be set to its value by the activity code. -->
    <ListPreference
        android:defaultValue="-1"
        android:entries="@array/pref_example_list_titles"
        android:entryValues="@array/pref_example_list_values"
        android:key="example_list"
        android:negativeButtonText="@null"
        android:positiveButtonText="@null"
        android:title="@string/pref_title_add_friends_to_messages" />

</PreferenceScreen>

And here is the java file of the first layout xml

public class FirstFragment extends Fragment {



    private View view;

    public FirstFragment(){


    }
    Button sendSMS;
    Button sendSMSaon;
    Button sendSMSaoff;
    Button sendSMSrela1;
    Button sendSMSrela2;
    EditText msgTxt;
    EditText aonTxt;
    EditText aoffTxt;
    EditText rela1txt;
    EditText rela2txt;
    Button taframnummer;

//Down below in Textview numTxt is where the value from the Edittextpreference will be shown

    TextView numTxt;
    



    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.first_layout, container, false);

    }


}

Really hope som1 can link a tutorial or something. This is almost the last part of my app! The project has been on and off for four months... Just because of the setting menu. Thing is i only need 1 option where the user can "save" a number to the textfield in the settings menu... :( — Tim, Sep 13 '16 at 19:00
Which specific value/variable in your code you want to save and write to textField? Also check: http://stackoverflow.com/questions/5821051/how-to-display-the-value-of-a-variable-on-the-screen http://stackoverflow.com/questions/23024831/android-shared-preferences-example — Fr333du, Sep 14 '16 at 06:44
Hi thanks for your answer. This is going to be an SMS app so the value is going to be numbers (phone number). And i can write the number in the edit text preference but i just want it to be shown to a textfield in the "normal layout" the mainscreen/fragment. — Tim, Sep 14 '16 at 10:34
I do not see any text field in your code, if you want to copy the value to the other activity (screen) you have to save the number using `SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE).edit(); editor.putString("numTxt", numTxt.getText()); editor.commit();` and retrieve the number in other activity using `SharedPreferences prefs = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE); String restoredText = prefs.getString("numTxt", null); TextView textView = (TextView) findViewById(R.id.textViewName); //your textField? textView.setText(restoredText);` — Fr333du, Sep 14 '16 at 10:44
I will try the code! Sorry! for now the textfield is actually, " EditText numTxt; " . but i will change it to textview. — Tim, Sep 14 '16 at 15:55
Try it and please write in comments if you have any problems. Added my comment as a potential answer. — Fr333du, Sep 15 '16 at 06:30

SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE).edit(); 
editor.putString("numTxt", numTxt.getText()); 
editor.commit();

and retrieve the number in other activity using

SharedPreferences prefs = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE); String restoredText = prefs.getString("numTxt", null); 
TextView textView = (TextView) findViewById(R.id.textViewName); //your textField?
textView.setText(restoredText);    
//or with EditText 
//EditText editText = (EditText) findViewById(R.id.editTextName);
//editText.setText(restoredText);
