Default ActionBar with Settings button

Although I am new in android developing, lately, I have been trying to add a settings button in the default ActionBar that Android Studio provides (as shown in the picture below). However, all the tutorials I have stamped on start with changing the app Theme to: android:theme="#style/Theme.APpCompat.Light.NoActionBar"
Is there any way I can avoid changing Theme and just add that setting about in the default ActionBar?

You can do this by inflating your menu to the toolbar.
Override this method in your java class.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.your_custom_menu,menu);
return true;
}
You custom menu should look something like this:
<?xml version="1.0" encoding="utf-8"?>
>
<item
android:id="#+id/night_mode"
android:title="?attr/theme_text"
app:showAsAction="never"
android:icon="?attr/theme_icon"/>
<item
android:id="#+id/action_about"
android:title="#string/about_text"
app:showAsAction="never"
android:icon="?attr/about_icon"/>
<item
android:id="#+id/action_logout"
android:title="#string/action_logout_text"
app:showAsAction="never"
android:icon="?attr/logout_icon"/>

Style applied to an AlertDialog not working correctly

I've been asked to match the look of an Alert Dialog in our app to the one used by the app's theme.
I managed to apply a style to all Alert Dialogs in the app using it as part of the app's theme, but there are situations where the style is not applying correctly.
It happens for example when the Alert Dialog contains a 'Single Choice List' as its' message.
The title looks fine, so is the background and the button bar, but the list itself is problematic.
At first, the radio buttons as well as their textual description were black colored, as if android is using the default color.
I somehow managed to color the radio buttons as I wish, by using these attributes:
<item name="android:colorControlNormal">#color/text_secondary</item>
<item name="android:colorControlActivated">#color/text_secondary</item>
But the text color still remains black, and I've tried EVERY possible text color attribute exposed by android.
It looks like this:
Now this is the full style defined for the Alert Dialogs:
<style name="GenericAlertDialog.Alter" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowAnimationStyle">#android:style/Animation.Dialog</item>
<item name="android:windowMinWidthMajor">#android:dimen/dialog_min_width_major</item>
<item name="android:windowMinWidthMinor">#android:dimen/dialog_min_width_minor</item>
<item name="android:windowTitleStyle">#style/DialogTitle</item>
<item name="android:textColor">#color/text_secondary</item>
<item name="android:textColorPrimary">#color/primary</item>
<item name="android:background">#color/window_background</item>
<item name="android:colorAccent">#color/accent</item>
<item name="android:textColorAlertDialogListItem">#color/text_secondary</item>
<!--<item name="android:textColorSecondary">#color/text_secondary</item>-->
<item name="android:colorControlNormal">#color/text_secondary</item>
<item name="android:colorControlActivated">#color/text_secondary</item>
</style>
This is my Theme definition:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:windowBackground">#color/window_background</item>
<item name="android:colorPrimary">#color/primary</item>
<item name="android:colorAccent">#color/accent</item>
<item name="android:textColorPrimary">#color/text_primary</item>
<item name="android:textColorSecondary">#color/text_secondary</item>
<item name="android:textColorHint">#color/text_hint</item>
<item name="android:buttonStyle">#style/GenericButton</item>
<item name="android:checkboxStyle">#style/GenericCheckBox</item>
<item name="android:alertDialogTheme">#style/GenericAlertDialog</item>
<item name="alertDialogTheme">#style/GenericAlertDialog</item>
</style>
This is the code I'm using to create a custom Alert Dialog:
AlertDialog.Builder dialogBuilder = null;
try
{
dialogBuilder = new AlertDialog.Builder(i_OwnerActivity, R.style.GenericAlertDialog_Alter);
LayoutInflater layoutInflater = i_OwnerActivity.getLayoutInflater();
// Inflate the dialog's custom title view and set it's text to the matching one to this class
View customTitleView = layoutInflater.inflate(R.layout.dialog_title, null);
TextView customTitleTextView = (TextView) customTitleView.findViewById(R.id.DialogTitleText);
// Set text of customTitleView
dialogBuilder.setCustomTitle(customTitleView);
// Create an event handler for clicking on the negative button
dialogBuilder.setNegativeButton(R.string.action_dialog_negative_cancel, new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface i_Dialog, int i_Which)
{
// Do Something
}
});
} catch (Exception e)
{
LogUtils.logException(AlterDialogUtils.class, e);
}
return dialogBuilder;
And finally, here's the code I'm using to create an Alert Dialog with a 'Single Choice List':
dialogBuilder.setSingleChoiceItems(R.array.squelch_modes, m_InitialState, new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialog, int which)
{
// Do Something
}
});
What am I doing wrong? How can I change the color of the text?
It is also worth saying that I'm using AppCompat's AlertDialog.

Just found this old post with Google, but since there is no answer I will add what did the trick in my case:
remove the android: prefix from the textColorAlertDialogListItem in your alertdialog style
<item name="textColorAlertDialogListItem">#color/text_secondary</item>
I guess that's because of the parent being an AppCompat theme, but I am not sure about this. I still added both (with and without prefix) in my style...

I know it's probably late... but here's your answer: android.support.v7.app.AlertDialog in AppCompat support library use this layout by default (unless you provide your own adapter) for singleChoiceDialog:
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/listPreferredItemHeightSmall"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="?attr/textColorAlertDialogListItem"
android:gravity="center_vertical"
android:paddingLeft="#dimen/abc_select_dialog_padding_start_material"
android:paddingRight="?attr/dialogPreferredPadding"
android:paddingStart="#dimen/abc_select_dialog_padding_start_material"
android:paddingEnd="?attr/dialogPreferredPadding"
android:drawableLeft="?android:attr/listChoiceIndicatorSingle"
android:drawableStart="?android:attr/listChoiceIndicatorSingle"
android:drawablePadding="20dp"
android:ellipsize="marquee" />
The attribute used to set this up in the theme is singleChoiceItemLayout so you can override it with your own layout to get whatever UI you want.
If you just want to change the text color just define the attribute textColorAlertDialogListItem as you can see from the layout it's the one used for android:textColor.
In general when I need something like this i go and look at the source code since it is available. The support libraries source code can be found here, while most of the framework source code can be find here.

How to change the selected item's background color in android navigation drawer?

I am using Navigation Drawer (using Navigation Drawer Activity) in android studio and its working fine.
But I want to change the Background Color of selected item in Drawer's item List. I want to change default Color to my custom Color.
Any idea ???

Create another xml layout under res ⇒ drawable named list_item_bg_pressed.xml with following content.
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"><gradient
android:startColor="#color/list_background_pressed"
android:endColor="#color/list_background_pressed"
android:angle="90" />
Create Selector
<item android:drawable="#drawable/list_item_bg_normal" android:state_activated="false"/>
<item android:drawable="#drawable/list_item_bg_pressed" android:state_pressed="true"/>
<item android:drawable="#drawable/list_item_bg_pressed" android:state_activated="true"/>

Changing theme of Android Application via CheckBox onClick

I am a new android developer and I am working on a project where I want to have custom color themes as an option in the settings in one of my apps. I have four check boxes, call them checkBox1, checkBox2, checkBox3, checkBox4. I also have four custom styles in my styles.xml file, call them theme1, theme2, theme3, theme4. Here is my .java file coding regarding handling the onClick of these CheckBoxes:
checkBoxListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
if(blueCheckBox.isChecked()){
//Change theme to blue
}
if(redCheckBox.isChecked()){
//Change theme to red
}
if(greenCheckBox.isChecked()){
//Change theme to green
}
if(bwCheckBox.isChecked()){
//Change theme to Black & White
}
}
};
blueCheckBox.setOnClickListener(checkBoxListener);
redCheckBox.setOnClickListener(checkBoxListener);
greenCheckBox.setOnClickListener(checkBoxListener);
bwCheckBox.setOnClickListener(checkBoxListener);
}
How can I set the style of my entire application to the corresponding custom declared styles I have in the body's of these if statements? Thank you for your time, I appreciate any help you can offer.

for this you have to create some themes under /style/
For Example :
<resources>
<style name="LightTheme" parent="#android:style/Theme.Light">
</style>
<style name="BlackTheme" parent="#android:style/Theme.Black">
</style>
</resources>
and at java side you can use it like...
if (lightThemeCheckBox.isChecked()) {
getApplication().setTheme(R.style.LightTheme);
} else {
getApplication().setTheme(R.style.BlackTheme);
}
i hope this will help you.

Hi You are able to supply the button for Checkbox by set the Background for the CheckBox as Follows :
Below the Code is for backgound xml file for Checkbox: Name as checkbox_selection.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/check_active_320" android:state_checked="true" android:state_focused="true"/>
<item android:drawable="#drawable/check_inactive_320" android:state_checked="false" android:state_focused="true"/>
<item android:drawable="#drawable/check_inactive_320" android:state_checked="false"/>
<item android:drawable="#drawable/check_active_320" android:state_checked="true"/>
Here You found that there was having the drawable resource such as check_active_320 when User checked on CheckBox and check_inactive_320 for Checkbox which is not checked.
the code to set the above xml to CheckBox as Follows:
<CheckBox
android:id="#+id/radioread"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/textread"
android:layout_alignBottom="#+id/textread"
android:layout_alignParentRight="true"
android:layout_marginRight="15dp"
android:button="#drawable/checkbox_selection"
android:focusable="false" />
Here You can find the android:button as the value of our style.

Getting Rid of (Hiding) Android TabWidget's "Focused State"

Okay, so here's the idea; I want to create a set of icons that persists on the bottom of the screen across all the activities I have on my app. The first thing that came to my mind was the TabWidget.
After I spent some time with it, I realized that I can't get the "focused state" off the tabs, I know tabs are supposed to work out that way but the idea is to making those tabs looks like icons - it shouldn't looked like they were focused all the time.
I tried using tabHost.setBackgroundColor(color) but unfortunately it did not work as I expected.
Here's some visualization to ease off the problem.. http://i.stack.imgur.com/uF7fu.png
p.s., sorry about the link. As a new user I weren't allowed to post images directly on the post.

One way to do this would be to use a custom Selector for the tab states that is identical regardless of whether or not the tab has focus. This might look something like this:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="#drawable/tab_unselected" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="#drawable/tab_unselected" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="#drawable/tab_unselected" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="#drawable/tab_unselected" />
<!-- Pressed -->
<item android:state_pressed="true" android:drawable="#drawable/tab_press" />
</selector>
You'd add that to your drawable directory, and then configure your tabwidget to use that in your activity (like so):
TabWidget tabWidget = getTabWidget();
for(int i = 0; i < tabWidget.getChildCount(); i++) {
RelativeLayout tabLayout = (RelativeLayout) tabWidget.getChildAt(i);
tabLayout.setBackgroundDrawable(res.getDrawable(R.drawable.tab_indicator));
}
A much more detailed guide is here. See if that works for you.

In general you should have a 'focused state' to indicate what is active for those devices without a touch screen (i.e. Google TV) or to assist the accessibility tools for the visually impaired. If you still want to go down the route of hiding the 'focused state' see Femi's answer regarding custom selector.

Modifying the selected style like Femi shows is the way to do this..
