In Android Studio why is there no TextViewPreference?

Question

Ok so I wanted to create a Settings activity. I was told using the Preference layout makes it much easier. I want a TextView that when clicked does a certain action, yet there is no TextViewPreference. The closest thing is EditTextPreference that must have the attribute "selectable" set to off which turns it gray.

Also another thing, these Preferences have no ID attribute. How am I supposed to attach OnClickListeners to them if they have no ID???

what functionality you want exactly....?your question is unclear...did you got solution what @Doc has given link? — Wini, Jul 10 '20 at 08:26

try-->

Method 1

create a custom preference layout item and use it in the Preference Activity:-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minHeight="?android:attr/listPreferredItemHeight"
android:gravity="center_vertical"
android:paddingRight="?android:attr/scrollbarSize">

    <TextView android:id="@android:id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:singleLine="true"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:ellipsize="marquee"
        android:fadingEdge="horizontal" />

  </LinearLayout>

add in preference xml:

<Preference
android:title="@string/label_pref_version"
android:key="@string/pref_version"
android:layout="@layout/pref" />

then lastly:-

fire findViewById in your Activity code and attach a listener....

Method 2

For the xml:

<Preference android:title="Acts like a text"
            android:key="@string/myCooltext"
            android:summary="This is a text"/>

Then for the java in your onCreate()

Preference text = findPreference(getString(R.string.myCoolText));
text.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {
            @Override
            public boolean onPreferenceClick(Preference preference) {   
                //code for what you want it to do   
                return true;
            }
        });

Method 3

You can try it like this to get the Textview in activity:

 View name= ((LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.layouttext, null, false);

add android:id to the LinearLayout that contains the Textview in layouttext.xml, i.e. android:id="@+id/mylayout"

 LinearLayout mLayout = (LinearLayout)name.findViewById(R.id.mylayout);
  Textview login = (Textview) footerView.findViewById(R.id.Text);
  login.setOnClickListener(this);

Hi. With method 2 I can't find a findPreference() method – User104163 Jul 10 '20 at 11:00

you are extending to what ? `PreferenceFragment` or `PreferenceActivity` ?????\ – Wini Jul 10 '20 at 11:02
The second. btw what is boolean for in public boolean onPreferenceClick(Preference preference)? – User104163 Jul 10 '20 at 11:21
Called when a Preference has been clicked.....True if the click was handled..... – Wini Jul 10 '20 at 11:25
What happens if it returns false? – User104163 Jul 10 '20 at 11:35

If you do not handle the click i.e. you don't do anything when this is clicked --> returning false – Wini Jul 10 '20 at 11:43
Is there a way other than findPreference to get a reference to a preference? I mean a way inside AppCompatActivity – User104163 Jul 10 '20 at 15:10
no there is no way through AppCompactactvity...you need you extend or implement using `PreferenceFragmentCompat` or `PrefernceActivity` or `PreferneceFragment` – Wini Jul 13 '20 at 10:28
Sorry. I tried both methods. Neither worked for various reasons. If there is a complete working example of findPreference can you post it? It's inside a static class which makes working with it impossible. – User104163 Jul 13 '20 at 20:41
added 3rd method...try this tooo – Wini Jul 14 '20 at 06:31
