Slider on my PreferenceScreen

Development issue/problem:

I want something in my settings menu that changes the duration of the vibration.

There is no sliding tag for prefs.xml, what is the best way to proceed?

How can I solve this problem?

Solution 1:

You can create your own preference class that expands the DialogPreference and displays the SeekBar as a dialog box.

Solution 2:

I have improved the link provided by Macarse, so that the value is only saved when you click ok, and you can @string/… Values in the XML file.

Here’s the code:

/* The following code is written by Matthew Wiggins

* Improvements :
* – Save the value on a positive click, do not change the search bar
* – @string/… Values in the xml file

EDIT:

Here’s a screenshot:

EDIT: At arlomedia’s request, here are all the necessary bits of code (I’ve just created a new project, it’s working fine. I fixed some bugs in the SeekBarPreference class, so don’t forget to copy/paste it again) :

Main activities :

Package and.at.test sliderpref ;

import android.app.Activity;
import android.content.intentional;
import android.os.bundle;
import android.view.Menu;
import android.view.MenuItem ;

the MainActivity public class expands the activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

@General Boolean menu
onCreateOptionsMenu(Menu) {

getMenuInflater().inflate(R.menu.main, menu);
return true;
}

@Public check boolean
onMenuItemSelected(int featureId, item MenuItem) {

switch(item.getItemId()) {

case R.id.menu_settings : {

startActivity (new intent (this, SettingsActivity.class)) ;

pause;
}
}

return where;
}
}

SettingsActivities :

Package and.at.test sliderpref ;

Import android.content.SharedPreferences;
import android.content.SharedPreferences.OnSharedPreferenceChangeListener;
import android.os.bundle;
import android.preference.PreferenceActivity;
import android.preferenceFragment;
import android.preference.PreferenceManager;
import and.at.testsliderpref.utils.SeekBarPreference ;

the SettingsActivity public class extends the SettingsActivity preferences {

@Override
protected empty onCreate(Bundle storedInstanceState) {

// Call the super:
super.onCreate(savedInstanceState) ;

// Set the activity clip:
getFragmentManager().beginTransaction().replace(android.R.id.content, new SettingsFragment()).commit();
}

public static class settingsFragment expands PreferenceFragment Implementation of OnSharedPreferenceChangeListener {

private SeekBarPref _searchBarPref ;

@Override
public void onCreate(Bundle storedInstanceState) {

super.onCreate(savedInstanceState) ;

// Load the parameters of the XML source

// Get Widgets:
_SearchBarPref = (SearchBarPreference) this.findPreference(SEEKBAR_VALUE) ;

// Set the listener:

// Set the search bar summary:
int radius = PreferencesManager.getDefaultSharedPreferences(this.getActivity()).getInt(SEEKBAR_VALUE, 50);
_seekBarPref.setSummary(this.getString(R.string.settings_summary).replace($1, +radius)));
}

@SharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {

// Set Search List Summary:int radius = PreferencesManager.getDefaultSharedPreferences(this.getActivity()).getInt(SEEKBAR_VALUE, 50);_seekBarPref.setSummary(this.getString(R.string.settings_summary).replace($1, +radius));}}.

Don’t forget to add your SettingsActivity to the manifesto and everything should be fine.

Solution 3:

An easy way to do this is to add an empty preference to your preferences.xml file that uses a layout with the search bar.

Add your preferences.xml

add a cursor under layouts

Solution 4:

If you have already switched to androidX, you can simply use androidx.preference.SeekBarPreference. Documentation here and here

Define it in XML as follows:

Pay attention: Now in Android Studio (my current version 3.2.1), the automatic preferences do not work for androidx.preference.preferencesScreen in prefs.xml, but don’t worry about the xml swell settings with setPreferencesFromResource() works fine. All required attribute names and component references can be found here.

Solution No 5:

This is a good Slider Preferences component – Android Slider Preferences Library

https://github.com/jayschwa/AndroidSliderPreference

Solution No 6:

Another version.
All credit goes to Tim Autin.

I wanted the values loaded from XML tables to be displayed.

That’s what it looks like.

final int progressChoice = mSeekBar.getProgress();
setValueIndex(progressChoice);
}

getDialog().dismiss();
}
}

Now use in the preset file

And the paintings

10 seconds
30 seconds
1 minute
2 minutes
unlimited

10
30
60
120
0

As a bonus, if you already have ListPreferences, you don’t have to add anything to display the summary as current value. So it works very well.

@Override
public blank onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
SetSummaryForPreferenceKey(key);
}

private void SetSummaryForPreferenceKey(String key) {
Preference = findPreference(key) ;

// This works with our new SeekBarPreference
, as (privileged ListPref instance) {
ListPref listPref = (ListPreference) privilege;
listPref.setSummary(listPref.getEntry());
}
} }.

Solution No 7:

I improved the code in Tim’s answer a little. This allows the output value to be changed simply when the cursor is moved, instead of the user having to press the OK button to make changes.

This is useful for things like the music volume control, where the user should be able to hear the volume setting as it is being made.

When the user presses OK, the new value is stored. When the user presses the Cancel button, the originally set value is restored.

Thanks and the honor goes to Tim, I just added an extra onClick listener and pushed the value of the update to the onChange listener.

Solution No 8:

A small improvement over Tim’s reaction and his distractions:

protected nullity onBindDialogView(View v) {
super.onBindDialogView(v);
mSeekBar.setMax(mMax);
mSeekBar.setProgress(mValue);
String t = String.valueOf(mValue);
mValueText.setText(mSuffix == null ? t : t.concat( + mSuffix));
}

At the beginning, the current value is entered, which is otherwise empty until you actually move the cursor.

Good luck!
