Dialog Builder in PreferenceFragment

seems to work fine So I decided that I would just implement an extended ListPreference which deals with creating the confirmation dialog and voila, It now works perfectly.
public class ThemeListPreference extends ListPreference {

    private int mClickedDialogEntryIndex;

    private Context mContext;

    public ThemeListPreference(Context ctxt) {
        this(ctxt, null);

    public ThemeListPreference(Context ctxt, AttributeSet attrs) {
        super(ctxt, attrs);

        mContext = ctxt;


    protected void onPrepareDialogBuilder(Builder builder) {
        if (getEntries() == null || getEntries() == null) {
            throw new IllegalStateException(
                    "ListPreference requires an entries array and an entryValues array.");

        mClickedDialogEntryIndex = findIndexOfValue(getValue());
        builder.setSingleChoiceItems(getEntries(), mClickedDialogEntryIndex,
                new DialogInterface.OnClickListener() {
                    public void onClick(final DialogInterface dialog, final int which) {
                        // Save preference and close dialog
                        mClickedDialogEntryIndex = which;

                        ThemeListPreference.this.onClick(dialog, DialogInterface.BUTTON_POSITIVE);

                        new AlertDialog.Builder(mContext)
                                .setPositiveButton(R.string.yes, new DialogInterface.OnClickListener() {

                                    public void onClick(DialogInterface dialog, int which) {
                                        Utils.changeTheme((Activity) mContext);

                                .setNegativeButton(R.string.no, new DialogInterface.OnClickListener() {

                                    public void onClick(DialogInterface dialog, int which) {


        builder.setPositiveButton(null, null);

    protected void onDialogClosed(boolean positiveResult) {

        CharSequence[] mEntryValues = getEntryValues();

        if (positiveResult && mClickedDialogEntryIndex >= 0 && mEntryValues != null) {
            String value = mEntryValues[mClickedDialogEntryIndex].toString();
            if (callChangeListener(value)) {

Android app : show PreferenceFragment as a dialog?

Tag : android , By : negonicrac
Date : March 29 2020, 07:55 AM
hope this fix your issue To do an old fashioned, single page settings screen without PreferenceHeaders, do as follows:
In your activity that invokes the settings screen (example is in onMenuItemSelected):
case R.id.menuSettings:
        Intent settingsIntent = new Intent(this, SettingsActivity.class);
        startActivityForResult(settingsIntent, GC.SETTINGS_ACTIVITY_ID);
package com.mycompany.project1;

import android.os.Bundle;
import android.preference.PreferenceActivity;
import android.preference.PreferenceFragment;

public class SettingsActivity extends PreferenceActivity {

    private final static String TAG = "SettingsAcitivity";

    public SettingsActivity() {}

    protected void onCreate(Bundle savedInstanceState) {
        MyLog.d(TAG, "onCreate");
                .replace(android.R.id.content, new LocationFragment()).commit();

    public static class LocationFragment extends PreferenceFragment {

        private String TAG = "LocationFragment";

        public void onCreate(Bundle savedInstanceState) {
            MyLog.d(TAG, "onCreate");

How can I display a Dialog from a PreferenceFragment?

Tag : android , By : cmhudson

this will help Building on Steve's answer, I also need to set up the DialogFragment to import from android.app.DialogFragment (instead of android.support.v4.app.DialogFragment). The show() function in that library asks for an android.app.FragmentManager, which I can provide via a call to getFragmentManager() as I did within the code I posted in the question.

File picker dialog in PreferenceFragment

it should still fix some issue I don't think Andorid have a native file chooser, so you'll have to implement one yourself, or find a library.
You could then use the android:onClick property in PreferenceFragment.xml:
    android:title="Database file"
public void startFileChooser(MenuItem i){
     // Start the file chooser here

With these it helps This is known issue the team is going to fix soon. It was reported here and here. To unblock yourself you can just re-compile the library using the latest version of BotBuilder, that will make the trick.

Android changing Dialog content of a PreferenceFragment

Tag : android , By : Robert M

should help you out You should implement Preference.OnPreferenceChangeListener for PreferenceFragment class. Then override onPreferenceChange method and if newValue is correct return true otherwise return false. If you return false then preference value will not change.
public class SettingsFragment extends PreferenceFragmentCompat implements
    Preference.OnPreferenceChangeListener {

       public boolean onPreferenceChange(Preference preference, Object newValue) {

             int number = 0;
                   number = Integer.parseInt(newValue.toString());
              }catch(Exception e){


              if (number > 0 && number < 10){    //It's an example
                     return true;                // Preference will change

              return false;          // newValue rejected and preference not change

public void onCreatePreferences(Bundle bundle, String s) {


    PreferenceScreen prefScreen = getPreferenceScreen();
    Preference editTextPrefernce = prefScreen.findPreference(getString(R.string.pref_key));

    if (editTextPrefernce != null && editTextPrefernce instanceof EditTextPreference) {
