Preference changes only happen when restarting the app

Hey there! I was coding an app I added a preferences menu, and it works, but changes happen only when I restart the application,anyone knows how to make changes happen whithout exitting the app??? Thanks in advance
My code ( from main activity):
preferencias = preferenceManager.getDefaultSharedPreferences(TimeToSpeechActivity.this);
OnSharedPreferenceChangeListener listener = new SharedPreferences.OnSharedPreferenceChangeListener() {
public void onSharedPreferenceChanged(SharedPreferences prefs, String key) {
//nothing here, do I have to put anything?
}
};
preferencias.registerOnSharedPreferenceChangeListener(listener);
getPrefs();
changefont(fuente, letra);
if (boole == true) {fontcolors();}
private void getPrefs(){
fuente = Typeface.createFromAsset(getAssets() , preferencias.getString("elegirfuente", "fonts/Default.ttf"));
letra = Integer.parseInt(preferencias.getString("fontstyle", "0"));
bol = preferencias.getBoolean("randomcolors", true);
}

Click to collapse
I have nothing put in preference activity, do i have to put anything?
Also, do I have to edit this?: (SharedPreferences prefs, String key) I ask this because i havent created prefs and key varibles
Thanks in advance!!!

It should update for you if you put getPrefs() inside the sharedpreferences listener
Sent from my Xoom using xda premium

thanks, but if I do that I get a nullpointer exception, I think its caused because the params I use to set "changefont(fuente, letra);" and "if (boole == true) {fontcolors();}" have null value....another idea ,please? I am breaking my head with this...
My updated code:
preferencias = preferenceManager.getDefaultSharedPreferences(Time ToSpeechActivity.this);
OnSharedPreferenceChangeListener listener = new SharedPreferences.OnSharedPreferenceChangeListener () {
public void onSharedPreferenceChanged(SharedPreferences prefs, String key) {
getPrefs();
}
};
preferencias.registerOnSharedPreferenceChangeListener(listener);
changefont(fuente, letra);
if (boole == true) {fontcolors();}
private void getPrefs(){
fuente = Typeface.createFromAsset(getAssets() , preferencias.getString("elegirfuente", "fonts/Default.ttf"));
letra = Integer.parseInt(preferencias.getString("fontstyle ", "0"));
bol = preferencias.getBoolean("randomcolors", true);
}

Click to collapse
i tried to put changefont and fontcolors functions inside the sharedpreference listener... but if i do, that options are not set... so I think there is a problem with the listener...why???
I will add the code of my preference class:
public class PantallaOpciones extends PreferenceActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.opciones);
}
}

One way ive always done preference updates was to use a dedicated method for updating (like you have with openPrefs()) then calling it after operations:
runOperation(){
updatePrefsMethod();
getPrefsMethod();
}
If i was near my pc i could give you a more solid example, but alas, im stuck at work lol
Also, use the stacktraces to check which line gives it null (itll say something like "at com.yourapp.identifier(offending Class - line number)
maybe if you a null check on the boolean for color that sets it false, you may not get the nullPointerException

[Q]need help to make an xposed module

I am trying to make an xposed module(private use) to implement clear all button(ImageView) in recents.
Here is my code
Code:
package com.mycompany.myapp3;
import android.graphics.*;
import android.view.*;
import android.widget.*;
import de.robv.android.xposed.*;
import de.*;
import de.robv.android.xposed.callbacks.*;
import de.robv.android.xposed.callbacks.XC_LoadPackage.*;
import static de.robv.android.xposed.XposedHelpers.findAndHookMethod;
public class MainActivity implements IXposedHookLoadPackage
{ImageView m;
String rc="com.android.systemui.recent.RecentsPanelView";
public void handleLoadPackage(final LoadPackageParam lpparam) throws Throwable
{
findAndHookMethod(rc, lpparam.classLoader, "updateClock", new XC_MethodHook() {
@Override
protected void afterHookedMethod(final MethodHookParam param) throws Throwable
{
m.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v)
{
ViewGroup mRecentsContainer = (ViewGroup) XposedHelpers.getObjectField(
param.thisObject, "mRecentsContainer");
// passing null parameter in this case is our action flag to remove all views
mRecentsContainer.removeViewInLayout(null);
}
});
}
});
}}
Now the problem is that i have already that ImageView in recent_panel.xml with no action assigned.i know its id and want to implement onclick action to that ImageView only by using its id.so what code should i add so that code recognises that ImageView and assigns it the above onclick action

It's only an idea and maybe it doesn't solve your problem: Have you tried to hook onCreate and use the this-Object to call findViewById?
And you are making a mistake: You have to look, whether the loaded package is your specific package you want to hook. You try to hook every app.

Try using an LruCache or your images. Also, you might want to take a look at this guide explaining it further.

[Guide] Listeners in Java development

You are new to java development and want to get buttons working?
Maybe you are a Pro but want a reminder?
whatever you are this Guide is to help you to make buttons/check boxes...etc working and functional
Some people are distracted between guides over internet and want the easiest way to get their project working, me too
Steps :
1-Define the button :
Code:
Button btn1;
Checkbox chkbox1;
RadioButton radio1;
2- Intialize it :
Code:
btn1 = (Button) findViewById(R.id.btn1);
chkbox1= (Checkbox ) findViewById(R.id.chkbox1);
radio1= (RadioButton) findViewById(R.id.radio1);
3-Add the listener :
Button:
Code:
btn1.setOnClickListener(new OnClickListener() {
@SuppressWarnings("deprecation")
@Override
public void onClick(View arg0) {
//Write awesome code here
}
});
CheckBox :
Code:
chkbox1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if (start.isChecked()) {
//if the checkbox checked
} else {
//if not checked
}
}
});
}
radio button:
Code:
public void onRadioButtonClicked(View view) {
boolean checked = ((RadioButton) view).isChecked();
switch(view.getId()) {
case R.id.radio1:
if (checked){
}
else{
}
break;
}
}
or use it in a radio Group :
Code:
public void onRadioButtonClicked(View view) {
// Is the button now checked?
boolean checked = ((RadioButton) view).isChecked();
// Check which radio button was clicked
switch(view.getId()) {
case R.id.radio1:
if (checked)
//Write code
break;
case R.id.radio2:
if (checked)
//Write code
break;
}
}
Also insted of this you can use a onCheckedChanged for a radio button (Thanks for GalaxyInABox)
Code:
@Override
public void onCheckedChanged(RadioGroup radioGroup, int i) {
switch (radioGroup.getCheckedRadioButtonId()) {
//Code
}
}
____________________________________________________________________
____________________________________________________________________
Also you can implement a Onclicklistener for the whole class to save resources : (thanks for @Jonny )
after defining and initializing your objects add this :
Code:
OnClickListener click_listener = new OnClickListener() {
public void onClick(View view) {
int id = view.getId();
if (id == your_id) {
//do stuff for this object
} else if (id == your_id2) {
//do other stuff for diffrent object
} else if (id == your_id3) {
//and so on
}
}
};
To do list :
-add on touch listeners
-add on drag listeners
Note : you can add a click listener to almost any thing (Textview or imageView or even EditText) just using the same method of adding listener to button
also there is some other ways to add a listener but this is the fastest and less disturbing :good:
If this guide is useful, press thanks

Yes, and now you can use
Code:
@Override
public void onCheckedChanged(RadioGroup radioGroup, int i) {
switch (radioGroup.getCheckedRadioButtonId()) {
//Code
}
}
to get the checked button. They are pretty much the same, but you can use view.getTag() easier in the first one.
And @mohamedrashad please show how to put the listener into a inner class. Many people don't know/use it, but it's that useful!

ok, i will add this

You can also add onClick property in XML and then handle it in a code.

Awesome tutorial! Thank you very much!
Please, you could share more related knowledge. It's really useful!

Also, an activity can be a listener. In this case:
MyActivity implements onClickListener {
btn1.setOnClickListener(this);
public void onClick (View v) {
//your code
}
}

For this kind of stuff, using some well known libraries from well known Android dev is a must.
https://github.com/JakeWharton/butterknife
Very powerfull, super easy to use, error prone and without any performance impact.

Mohamedrashad. Thanks a lot.
Sent from my P880 using Tapatalk

If you have multiple clickable objects then it's best to use just 1 onClickListener for all of them and use a switch on their ID's. This reduces resource usage as you only have 1 listener, not 5, 10 or however many you would have otherwise. It's not essential for this but it is a best practice if you want to streamline your code.
Mobile right now so I can't chuck up an example until tomorrow evening or so.

You dude had a great thread. Its helping me. Bravoo !!

As @Jonny already pointed out: Use your class as a listener instead of creating a new (anonymous) inner class! Say you have a ListView, instead of doing this:
Code:
class MyFragment extends Fragment {
private void someMethod() {
((ListView) getView().findViewById(R.id.someListView)).setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//Code...
}
});
}
}
you can do this:
Code:
class MyFragment extends ListFragment implements AdapterView.OnItemClickListener, View.OnClickListener {
private void someMethod() {
((ListView) getView().findViewById(R.id.someListView)).setOnItemClickListener(this);
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//Code...
}
}
This may look stupid, but when you have many listeners, you can un-clutter it. In my opinion this is the best way. You can also add "this" class as listener for as many ui elements as you want(because all of them extend view, you can use one OnClickListener), then you only need to have a switch statement to distinguish between the views. And voila, you prevented cluttering the code with boilerplate stuff.

Example using code in an app I'm making - app for my school.
Code:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// Some code here for view/layouts etc
websitebutton = (Button) view.findViewById(R.id.website_btn);
facebookbutton = (Button) view.findViewById(R.id.facebook_btn);
twitterbutton = (Button) view.findViewById(R.id.twitter_btn);
websitebutton.setOnClickListener(handler);
facebookbutton.setOnClickListener(handler);
twitterbutton.setOnClickListener(handler);
return view;
}
OnClickListener handler = new OnClickListener() {
public void onClick(View view) {
switch (view.getId()) {
case R.id.website_btn :
Uri website = Uri.parse("http://wirralgrammarboys.com/");
Intent websiteintent = new Intent(Intent.ACTION_VIEW, website);
startActivity(websiteintent);
break;
case R.id.facebook_btn :
Uri facebook = Uri.parse("https://www.facebook.com/WirralGSB");
Intent facebookintent = new Intent(Intent.ACTION_VIEW, facebook);
startActivity(facebookintent);
break;
case R.id.twitter_btn :
Uri twitter = Uri.parse("https://twitter.com/WGSB");
Intent twitterintent = new Intent(Intent.ACTION_VIEW, twitter);
startActivity(twitterintent);
break;
}
}
};

// TODO Auto-generated constructor stub
}
// Binder given to clients
/**
* Class used for the client Binder. Because we know this service always

Intent intent = new Intent("notify");

for(int i=0;i<outputPath.size();i++){a.add(outputPath.get(i).getPath());}
intent.putStringArrayListExtra("path", a);
sendBroadcast(intent);
} private void publishResults(String a) {
Intent intent = new Intent("current");
intent.putExtra("name", a);
sendBroadcast(intent);
}}

I am using it like this
Code:
final Intent intent = new Intent(getActivity(), SearchService.class);
intent.putExtra("path",fpath);
intent.putExtra("name",a);
p=new ProgressDialog(getActivity());
p.setCancelable(false);
p.setTitle("Searching Files");
p.setMessage("Please Wait");
p.getWindow().addFlags( WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON );
p.setButton("Cancel", new DialogInterface.OnClickListener(){
public void onClick(DialogInterface p1, int p2)
{
getActivity().stopService(new Intent(getActivity(),SearchService.class));
// TODO: Implement this method
}
});
p.show();
getActivity().startService(intent);
but even after pressing cancel button,broadcast is received in activity

A service to display a toast and brodcast the data it recieved looks like a design flaw
anyways you are extending the intent service i guess it does not implement stopService() rather it stops automatically when it has nothing to do[not sure with it please check documentation for IntentService never actually used one of those ]
I guess you need to extend the Service class from package android.app

Actually I am using toast just for debugging.I am learning services. so I might be wrong at places.I made this service to search for files while an indeterminate progress dialog shows in activity till the broadcast of result is received.
I used intentservice because it was supposed to do one work at a time.please suggest me exact ways to use service in my case.I also want to make sure that if activity is paused(minimized) then, when task is completed activity is also started

You can still use an IntentService to do that. To stop it just pass an Intent to it with a boolean extra indicating that you don't want to do anything. You'll need only one more if clause in the onHandleIntent of the service.

First, if you look in the Dokumentation for IntentService, it says that you should not call stopSelf because it is already implemented to do that when there are no intents left. So It really should be easier to use a Service if you want to stop it like that.
If you want to keep using the intent service, I'd instead use a boolean instance variable which is checked in the publishResults method so just let the service do its work, but before it is published in the UI thread check if the dialog was canceled or not. Otherwise because you have two threads you can't be sure when the other thread receives the boolean change.
To me it seems like you could also use an AsyncTask to handle the threading and that class is easily cancelable .

I cannot use Asynctask ,as operation could be long.checking the boolean before publish is good idea.I will try this
