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:key="example_list"
android:negativeButtonText="@null"
android:positiveButtonText="@null"
android:title="@string/pref_title_add_friends_to_messages" />

}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);
//or with EditText
//EditText editText = (EditText) findViewById(R.id.editTextName);
//editText.setText(restoredText);
