I am getting a RuntimeException on Android 2.3.5 but I am using Theme.AppCompat (res/values/themes.xml). This is the phone: http://www.gsmarena.com/samsung_galaxy_y_s5360-4117.php

 <!-- res/values/themes.xml -->
 <?xml version="1.0" encoding="utf-8"?>

     <style name="Theme.Styled" parent="@style/Theme.AppCompat">
         <item name="actionBarStyle">@style/QueryActionBar</item>
         <item name="android:actionBarStyle">@style/QueryActionBar</item>

     <style name="QueryActionBar" parent="@style/Widget.AppCompat.ActionBar">
         <item name="background">@color/blueback</item>
         <item name="android:background">@color/blueback</item>
         <item name="backgroundSplit">@color/blueback</item>
         <item name="android:backgroundSplit">@color/blueback</item>


Here is the file for values-v11.

 <!-- res/values-v11/themes.xml -->
 <?xml version="1.0" encoding="utf-8"?>
    <style name="QueryTheme" parent="@android:style/Theme.Holo">
    <!-- Any customizations for your app running on devices with Theme.Holo here -->

Here is the error.

Sorry folks, I also do have android:theme="@style/Theme.Styled" defined in AndroidManifest.xml.

Solution 1

If you are extending ActionBarActivity in your MainActivity, you will have to change the parent theme in values-v11 also.
So the style.xml in values-v11 will be -

 <!-- res/values-v11/themes.xml -->
 <?xml version="1.0" encoding="utf-8"?>
    <style name="QueryTheme" parent="@style/Theme.AppCompat">
    <!-- Any customizations for your app running on devices with Theme.Holo here -->

EDIT: I would recommend you stop using ActionBar and start using the AppBar layout included in the Android Design Support Library

Solution 2

To simply add ActionBar Compat your activity or application should use @style/Theme.AppCompat theme in AndroidManifest.xml like this:

        android:theme="@style/Theme.AppCompat" />

This will add actionbar in activty(or all activities if you added this theme to application)

But usually you need to customize you actionbar. To do this you need to create two styles with Theme.AppCompat parent, for example, "@style/Theme.AppCompat.Light". First one will be for api 11>= (versions of android with build in android actionbar), second one for api 7-10 (no build in actionbar).

Let's look at first style. It will be located in res/values-v11/styles.xml . It will look like this:

<style name="Theme.Styled" parent="@style/Theme.AppCompat.Light">
    <!-- Setting values in the android namespace affects API levels 11+ -->
    <item name="android:actionBarStyle">@style/Widget.Styled.ActionBar</item>

<style name="Widget.Styled.ActionBar" parent="@style/Widget.AppCompat.Light.ActionBar">
    <!-- Setting values in the android namespace affects API levels 11+ -->
    <item name="android:background">@drawable/ab_custom_solid_styled</item>
    <item name="android:backgroundStacked"
    <item name="android:backgroundSplit"

And you need to have same style for api 7-10. It will be located in res/values/styles.xml, BUT because that api levels don't yet know about original android actionbar style items, we should use one, provided by support library. ActionBar Compat items are defined just like original android, but without "android:" part in the front:

<style name="Theme.Styled" parent="@style/Theme.AppCompat.Light">
    <!-- Setting values in the default namespace affects API levels 7-11 -->
    <item name="actionBarStyle">@style/Widget.Styled.ActionBar</item>

<style name="Widget.Styled.ActionBar" parent="@style/Widget.AppCompat.Light.ActionBar">
    <!-- Setting values in the default namespace affects API levels 7-11 -->
    <item name="background">@drawable/ab_custom_solid_styled</item>
    <item name="backgroundStacked">@drawable/ab_custom_stacked_solid_styled</item>
    <item name="backgroundSplit">@drawable/ab_custom_bottom_solid_styled</item>

Please mark that, even if api levels higher than 10 already have actionbar you should still use AppCompat styles. If you don't, you will have this error on launch of Acitvity on devices with android 3.0 and higher:

java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

Solution 3

Check and make sure that you do not have another values folder that references theme.styled and does not use AppCompat theme

ie values-v11 folder

Solution 4

Try this...


 <style name="Theme.AppCompat.Light.NoActionBar" parent="@style/Theme.AppCompat.Light">
    <item name="android:windowNoTitle">true</item>


            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />

Solution 5

Your Activity is extending ActionBarActivity which requires the AppCompat.theme to be applied. Change from ActionBarActivity to Activity or FragmentActivity, it will solve the problem.

Solution 6

Just do it Build -> Clean Project. I think this will solve your problem.

Solution 7

My manifest does not reference any themes... it should not have to AFAIK

Sure it does. Nothing is going to magically apply Theme.Styled to an activity. You need to declare your activities -- or your whole application -- is using Theme.Styled, e.g., :


Solution 8

I had such crash on Samsung devices even though the activity did use Theme.AppCompat. The root cause was related to weird optimizations on Samsung side:

- if one activity of your app has theme not inherited from Theme.AppCompat
- and it has also `android:launchMode="singleTask"`
- then all the activities that are launched from it will share the same Theme

My solution was just removing android:launchMode="singleTask"

Solution 9

I encountered this error when I was trying to create a DialogBox when some action is taken inside the CustomAdapter class. This was not an Activity but an Adapter class. After 36 hrs of efforts and looking up for solutions, I came up with this.

Send the Activity as a parameter while calling the CustomAdapter.

CustomAdapter ca = new CustomAdapter(MyActivity.this,getApplicationContext(),records);

Define the variables in the custom Adapter.

Activity parentActivity;
Context context;

Call the constructor like this.

public CustomAdapter(Activity parentActivity,Context context,List<Record> records){

And finally when creating the dialog box inside the adapter class, do it like this.

AlertDialog ad = new AlertDialog.Builder(parentActivity).setTitle("Your title");

and so on..

I hope this helps you

Solution 10

I just get my application move from ActionBarSherlock to ActionBarCompat. Try declare your old theme like this:

<style name="Theme.Event" parent="Theme.AppCompat">

Then set the theme in your AndroidManifest.xml:


Solution 11

in my case i made a custom view i added to custom view constructor

new RoomView(getAplicationContext());

the correct context is activity so changed it to:

new RoomView(getActivity());


new RoomView(this);

Solution 12

For my list view am using custom Adapter which extends ArrayAdapter. in listiview i have 2 buttons one of the buttons as Custom AlertDialogBox. Ex: Activity parentActivity; Constructor for Adapter `

public CustomAdapter(ArrayList<Contact> data, Activity parentActivity,Context context) {
        this.mContext   =   context;
        this.parentActivity  =   parentActivity;

` calling Adapter from MainActivty

adapter = new CustomAdapter(dataModels,MainActivity.this,this);

now write ur alertdialog inside ur button which is in the Adapter class

viewHolder.update.setOnClickListener(new View.OnClickListener() {
            public void onClick(final View view) {

                AlertDialog.Builder alertDialog =   new AlertDialog.Builder(parentActivity);

                LayoutInflater layoutInflater   = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                 @SuppressLint("InflateParams") final View view1   =   layoutInflater.inflate(R.layout.dialog,null);
                alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialogInterface, int i) {
                alertDialog.setPositiveButton("Update", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialogInterface, int i) {

                    //ur logic

para resolver o meu problema, eu apenas adicionei na minha MainActivity ("Theme = To solve my problem, I just added it in my MainActivity ("Theme =" @ style / MyTheme "") where MyTheme is the name of my theme

[Activity(Label = "Name Label", MainLauncher = true, Icon = "@drawable/icon", LaunchMode = LaunchMode.SingleTop, Theme = "@style/MyTheme")]
