android-support-v4-preferencefragment's Issues

Not work with RingtonePreference

It not works with RingtonePreference, not save the new value

findPreference return null in api 10

public class SettingsFragment extends PreferenceFragment implements OnPreferenceClickListener {
@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.preferences);
        Preference prefAbout = (Preference) findPreference(PREFERENCE_ABOUT_KEY);

findPreference(PREFERENCE_ABOUT_KEY) return null only in api 10
in api 16+ working good

        prefAbout.setOnPreferenceClickListener(new OnPreferenceClickListener() {
            @Override
            public boolean onPreferenceClick(Preference preference) {
                AboutDialogFragment af = new AboutDialogFragment();
                af.show(getFragmentManager(), TAG_DIALOG_ABOUT);
                return true;
            }
        });
        .......
    }
        .......
}

blank fragment

Hello...

I am getting no error messages but the fragment is empty code snips below.

What am i doing wrong ?

import android.os.Bundle;
import android.support.v4.preference.PreferenceFragment;

public class FragmentQuickPrefs extends PreferenceFragment {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Load the preferences from an XML resource
        addPreferencesFromResource(R.xml.preferences);
    }
}

xml/preferences.xml

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

    <PreferenceCategory
        android:key="first_category"
        android:title="First Category" >
        <CheckBoxPreference

            android:summary="Define how often updates will be performed"
            android:title="Updates interval" />
    </PreferenceCategory>

</PreferenceScreen>

Sample app code?

Can you please put a sample of how to use the library?

I know it's very easy to make it, but I think that every library should offer a sample.

Push lib to Maven Central/jCenter

Now it's pain to include the library.

Plugin is too old

After the update to android studio 1.1 and setting of Gradle plugin version 1.1.0. I am getting this error. Please advise, Thanks.

Error:(12, 0)
Plugin is too old, please update to a more recent version,
or set ANDROID_DAILY_OVERRIDE environment variable to

Context menu items are the wrong color when using a app theme besides Theme.AppCompat

Hello, when using your library if the app theme is set to anything other than Theme.AppCompat and the preference screen contains an EditTextPreference when highlighting text the action bar context menu items are invisible because they are the same color as the action bar:

If you change the theme to Theme.AppCompat everything works fine:

I wrote a sample application to reproduce this issue:
https://github.com/wseemann/PreferenceTest

This Handler class should be static or leaks might occur: Handler

I'm getting this warning in Android Studio 1.1 for the code in PreferenceFragment.java

private Handler mHandler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        switch (msg.what) {

            case MSG_BIND_PREFERENCES:
                bindPreferences();
                break;
        }
    }
};

More info how it can be fixed.

NoClassDefFoundError R$layout

I am sure I am doing something wrong, but after struggling with this for a couple of days, I am hoping opening an issue will provide a resolution. I included the android-support-v4-preferencefragment in my Maven project as a dependency. When I attempt to run my application, it throws a NoClassDefFoundError for android.support.v4.preferencefragment.R$layout. Looking at the .aar file included in the downloaded zip, there is no R.class file, or an R$layout.class file (for the inner static class). I attempted to build it myself and while a BuildConfig.class is included, no R.class. Being more familiar with Maven than Gradle, I created a pom.xml and built the project, and again, no R.class. So suspecting that it was not the build tool, but an Android tool behavior that was the problem, I went on the android-dev IRC channel. A gentleman named pfn informed me that the .aar spec does not allow for R.class(s) to be in an .aar. So it is filtering out the R.class. But if that is the case, then obviously I am using this library incorrectly. Could someone please let me know why this might be happening? Below is the stack trace:

Listeners are not working?

I can't seem to get any listeners working with this library. Is there a fix for this? Or a certain workaround? Maybe anybody else has a solution?

I created a test-project at: https://github.com/agrajaghh/PreferenceFragment-Test following the guidlines at https://developer.android.com/guide/topics/ui/settings.html#PreferenceHeaders

The PreferenceActivity looks like this:

package org.testing.preferencefragment_test;

import android.os.Bundle;
import android.preference.PreferenceActivity;
// Not working:
import android.support.v4.preference.PreferenceFragment;
// working:
//import android.preference.PreferenceFragment;

import java.util.List;

public class ApplicationPreferencesActivity extends PreferenceActivity {
  @Override
  public void onBuildHeaders(List<Header> target) {
    loadHeadersFromResource(R.xml.preference_headers, target);
  }

  @Override
  protected boolean isValidFragment (String fragmentName)
  {
    return (SettingsFragmentTest.class.getName().equals(fragmentName));
  }

  public static class SettingsFragmentTest extends PreferenceFragment {
    @Override
    public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      addPreferencesFromResource(R.xml.settings_test);
    }
  }
}

with preference_headers.xml:

<?xml version="1.0" encoding="utf-8"?>

<preference-headers xmlns:android="http://schemas.android.com/apk/res/android">
    <header android:fragment="org.testing.preferencefragment_test.ApplicationPreferencesActivity$SettingsFragmentTest"
            android:title="TEST" />
</preference-headers>

and settings_test.xml:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <CheckBoxPreference
        android:key="pref_test1"
        android:title="Test1_Title"
        android:defaultValue="true" />
</PreferenceScreen>

When I replace import android.support.v4.preference.PreferenceFragment; with import android.preference.PreferenceFragment; its working. Could I do anything about it, or is it a bug/missing feature of this library?

Can you add a license statement in your readme.md?

Put it on Maven Central

This would make usage easier, as you'd just have to add something similar to compile 'com.android.support:appcompat-v7:19.1.+' to your build.gradle file.

Don't pay attention to the Toolbar.

Can fix ?

Memory leak when using soft keyboard

I was using android-support-v4-preferencefragment along with ActionBarSherlock and jfeinstein10/SlidingMenu。If my application popped up a dialog, or an activity int dialog style, to have something input, memory leak happened upon the soft keyboard, to cause ANR and finally crash. If I remove PreferenceFragment, and just popped up the same thing from within SlidingMenu, it work fine. So I think it should be an issue of PreferenceFragment.

The following are the logs captured in a simulator of Android 2.3.3 and a device in Android 4.1.2. Not happened in all the devices.

Any help would be appreciated.
