In Stripe Android CardWidget How to change hint text size and hint text?

I m using Stripe library stripe-android:6.1.2.
I have integrated Stripe provide Card widget for android.
It's very clumsy. Card number overlaps MM/YYYY etc. Also textSize is large. Want to make it Small.
Need help in customising these attributes.

As per the Stripe doc: https://stripe.com/docs/mobile/android
You can try:
<style name="CardWidgetStyle" parent="#android:style/Theme.DeviceDefault">
<item name="android:background">#0000FF</item>
<item name="editTextStyle">#style/EditTextOverride</item>
<item name="android:editTextStyle">#style/EditTextOverride</item>
</style>
<style name="EditTextOverride" parent="#android:style/Widget.EditText">
<item name="android:textColor">#FF0000</item>
<item name="android:textColorHint">#00FF00</item>
<item name="android:textSize">12sp</item>
</style>
Then in your layout file, apply the style to the CardInputWidget to change its text, text hint, and background colors.
<com.stripe.android.view.CardInputWidget
android:id="#+id/card_input_widget"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/CardWidgetStyle"
/>

For hint text If you implemented stripe version above 10.4.0 you may use setCardHint() works for both CardMultilineWidget and CardInputWidget, otherwise for CardInputWidget you can add one of the following attributes in your resource file
stripe:cardHintText="xxxx xxxx xxxx xxxx"
app:cardHintText="xxxx xxxx xxxx xxxx"

Stripe CardInputWidget documentation says here:
https://stripe.dev/stripe-android/
The individual EditText views of this widget can be styled by defining a style Stripe.CardInputWidget.EditText that extends Stripe.Base.CardInputWidget.EditText.
I created a style:
<style name="Stripe.CardInputWidget.EditText" parent="Stripe.Base.CardInputWidget.EditText">
<item name="android:textColorHint">#808080</item>
<item name="android:textSize">12sp</item>
<item name="android:textColor">#color/text_color</item>
</style>
and applied it to the widget
<com.stripe.android.view.CardInputWidget
android:id="#+id/cardInputWidget"
style="#style/Stripe.CardInputWidget.EditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/bg_box_blue_line"
android:padding="5dp">
</com.stripe.android.view.CardInputWidget>

for CardMultilineWidget if you want to change the hintTextSize
Go to your base theme and add
<item name="android:textSize">14sp</item> //use your preferred hint size

This worked for me:
style.xml
<style name="CardTheme">
<item name="colorPrimary">#color/white</item>
<item name="colorPrimaryDark">#color/dark</item>
<item name="android:textColorHint">#color/grey</item>
<item name="colorAccent">#color/white</item>
<item name="colorControlNormal">#color/white</item>
<item name="colorControlActivated">#color/white</item>
<item name="android:editTextColor">#color/white</item>
</style>
activity_card.xml
<com.stripe.android.view.CardMultilineWidget
android:id="#+id/card_widget"
android:theme="#style/CardTheme"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true" />

How to give the user the possibility to switch between different colors skin in your App

I want to give the user the opportunity to select wich color skin will have the app. For example, i whould implement a black skin with black colours with different tonalities and also a white skin with withe tonalities.
Which whould be the best approach to achieve this?
For example i know that there is a colors.xml file in Android that should contain the colours of your app. Whould be a way to have two colors files or something and to use one or other depending of user selection? Maybe a styles.xml file?
Please tell me your opinion about which whould be the best approach to achieve this
Thank you

Regarding to #Joaquim Ley's answer we can change Theme before super.onCreate() .
In my app(at work) my styles.xml :
This is my default theme
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="android:colorAccent">#color/colorPrimary</item>
<item name="android:statusBarColor">#color/colorPrimaryDark</item>
<item name="android:colorFocusedHighlight">#color/colorPrimary</item>
<item name="android:colorControlNormal">#color/amber_300</item>
<item name="android:colorControlActivated">#color/amber_300</item>
<item name="android:colorControlHighlight">#color/colorControlHighlight</item>
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
<item name="android:windowTranslucentStatus">false</item>
<item name="actionBarItemBackground">?attr/selectableItemBackground</item>
<item name="colorControlHighlight">#color/colorControlHighlight</item>
<item name="android:windowContentTransitions">true</item>
<!-- Customize your theme here. -->
</style>
And this is my Green Theme :
<style name="AppTheme.Green" parent="AppTheme">
<item name="colorPrimary">#color/green_500</item>
<item name="colorPrimaryDark">#color/green_700</item>
<item name="android:colorAccent">#color/green_300</item>
<item name="android:statusBarColor">#color/green_700</item>
<item name="android:colorFocusedHighlight">#color/green_500</item>
<item name="android:colorControlNormal">#color/green_300</item>
<item name="android:colorControlActivated">#color/green_300</item>
</style>
When changing theme :
#Override
protected void onCreate(Bundle savedInstanceState) {
mPrefs=getSharedPreferences(getResources().getString(R.string.preference_name),MODE_PRIVATE);
mEditor=mPrefs.edit();
mEditor.apply();
defaultColor=mPrefs.getInt(getResources().getString(R.string.default_color),0);
//you can do some switch case or if else of defaultColor and change theme
setTheme(R.style.AppTheme_Green);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add_voice_record);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
This is my first app in work, but in my personal app i created a BaseActivity and created a method handleColor(int color,int darkcolor). But this won't change entire theme just Toolbar, StatusBar, NavigationBar and EditText marker and underline colors:
public class BaseActivity extends AppCompatActivity {
public void handleColor(int color,int darkcolor){
//changing toolbar color
if(getSupportActionBar()!=null){
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(color));
}
//if bigger than Api 21 change status bar color
if(isLolipop()){
Window window = getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(darkcolor);
}
}
public boolean isLolipop(){
return Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP;
}
}
When changing color i am using Material Dialogs Color Picker. Sample apk : sample.apk and Github: material-dialogs. If you want to see how it looks like i can give you a video of my app.
Colors from : Material Color Palette
Anyways i know 2 different approach , if you like one of them i can explain more.
#Edit : Good news for you, I found this Github repo : app-theme-engine and its working good. You can try sample apk. If you can't import it via gradle try this : compile 'com.github.naman14:app-theme-engine:0.5.1#aar'

This should be done in the styles/AppTheme.xml
It’s only possible to change the theme of an Activity in the onCreate() method and that to only before super() has been called. Changing the theme is fairly straight forward, something like below should do it:
setTheme(someBooleanFlag ? R.style.AppThemeOne : R.style.AppThemeTwo);

Support Action Bar not applying my style?

I've been spending hours trying to fix the changing action bar title size according to this stack overflow post:
Android Toolbar: small title text in landscape mode
Unfortunately, it seems that no matter what I do, anything regarding the actionbar style won't actually apply.
My styles v14 file:
<!-- Main theme -->
<style name="MyTheme" parent="Theme.AppCompat">
<item name="android:actionBarItemBackground">#drawable/selectable_background</item>
<item name="android:popupMenuStyle">#style/PopupMenu</item>
<item name="android:dropDownListViewStyle">#style/DropDownListView.MyTheme</item>
<item name="android:actionBarTabStyle">#style/ActionBarTabStyle.MyTheme</item>
<item name="android:actionDropDownStyle">#style/DropDownNav.MyTheme</item>
<item name="android:spinnerItemStyle">#style/Widget.MyTheme.TextView.SpinnerItem</item>
<item name="android:spinnerDropDownItemStyle">#style/Widget.MyTheme.DropDownItem</item>
</style>
My ActionBar styles:
<style name="Widget.MyTheme.ActionBar" parent="#style/Widget.AppCompat.ActionBar.Solid">
<item name="android:background">#drawable/ab_solid</item>
<item name="android:titleTextStyle">#style/my_title_style</item>
</style>
<style name="my_title_style" parent="#style/TextAppearance.AppCompat.Widget.ActionBar.Title">
<item name="textSize">20sp</item>
</style>
And, of course, "MyTheme" is applied in the manifest as well - I've even tried adding it to all the individual activities as well, to no avail.
It seems that no matter what I do, stuff just won't apply. I've tried removing the android: namespace, I've tried using titleTextAppearance instead of titleTextStyle, I've basically emulated exactly how the parent themes do it, but it won't change anything. Anybody have a clue as to what's going on? I just recently updated to AppCompat so I'm not totally familiar with how everything works.

You need to use
<item name="background">#drawable/ab_solid</item>
<item name="titleTextStyle">#style/my_title_style</item>
for support library compatibility into your style.
Read Styling the Action Bar, section "For Android 2.1 and higher". Where it is given that you need to use two entries like
<style name="CustomActionBarTheme"
parent="#style/Theme.AppCompat.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/MyActionBar</item>
<!-- Support library compatibility -->
<item name="actionBarStyle">#style/MyActionBar</item>
</style>
So your complete style would be
<style name="Widget.MyTheme.ActionBar" parent="#style/Widget.AppCompat.ActionBar.Solid">
<item name="android:background">#drawable/ab_solid</item>
<item name="android:titleTextStyle">#style/my_title_style</item>
<item name="background">#drawable/ab_solid</item>
<item name="titleTextStyle">#style/my_title_style</item>
</style>

I don´t know if it's all that ou have made, but you have to add this code in the manifest(in the activity you want to apply this style):
<activity
android:name=".MyActivity"
android:label="#string/appName"
android:theme="#style/my_little_style" >
</activity>

Try in this way:
Create a layout for your Toolbar and put a TextView:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
android:id="#+id/toolbar"
android:background="#b2b2b2">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/toolbar_title"
android:textSize="20sp"
android:textColor="#ff282828"/>
</android.support.v7.widget.Toolbar>
Include the layout in your .xml:
<include layout="#layout/toolbar_activities"
android:id="#+id/toolbar_layout"/>
Finally set a title in your java class:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar_layout);
TextView mTitle = (TextView) toolbar.findViewById(R.id.toolbar_title);
mTitle.setText("Your Title");
setSupportActionBar(toolbar)

Custom preference layout widget not visible

edit:
for anyone coming across this, the way I got it to work is to either:
Set the layout directly for each preference item, as in:
<CheckboxPreference
android:layout="#layout/checkbox_preference_item"/>
OR set the style via a theme as I was doing before, but define a widgetlayout and set it instead of an actual layout, like so, where preferenceStyle is set to #style/Preference and checkBoxPreferenceStyle is set to #style/Preference.Checkbox:
<Style name="Preference">
<item name="android:layout">#layout/checkbox_preference_item</item>
</Style>
<Style name="Preference.Checkbox">
<item name="android:widgetLayout">#layout/your_custom_widget</item>
</Style>
I'm trying to customize the layout of a Checkbox Preference item and the checkbox itself is not showing up. I'm modeling after android code and not sure where I'm going wrong. The text views are working fine as well as the rest of the layout but the checkbox is not showing up. Would appreciate any help with this.
Relevant code:
theme.xml:
<style name="Theme.Settings" parent="android:Theme.Holo.Light">
<item name="android:actionBarStyle">#style/SettingsActionBarStyle</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:preferenceCategoryStyle">#style/PreferenceCategory</item>
<item name="android:preferenceStyle">#style/Preference</item>
<item name="android:checkBoxPreferenceStyle">#style/Checkbox</item>
</style>
style.xml
<style name="Checkbox">
<item name="android:layout">#layout/checkbox_preference_item</item>
</style>
<style name="Preference.Text">
<item name="android:layout_height">wrap_content</item>
<item name="android:layout_width">wrap_content</item>
<item name="android:fontFamily">sans-serif-light</item>
<item name="android:textSize">#dimen/preferences_item_font</item>
<item name="android:textColor">#color/preference_text</item>
</style>
<style name="Preference.Text.Extra" parent="Preference.Text">
<item name="android:textSize">#dimen/preferences_header_font</item>
</style>
checkbox_preference_item.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="#dimen/preferences_item_height"
android:background="#color/white"
android:paddingLeft="#dimen/preferences_item_left">
<LinearLayout android:layout_width="wrap_content"
android:orientation="vertical"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:gravity="center_vertical">
<TextView android:id="#android:id/title"
style="#style/Preference.Text"/>
<TextView android:id="#android:id/summary"
style="#style/Preference.Text.Extra"/>
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical"
android:visibility="visible"
android:id="#android:id/widget_frame"
android:layout_alignParentRight="true"/>
</RelativeLayout>

I am not seeing a CheckBox in the layout xml. Am I missing something? You need to specify something like:
<CheckBox android:id="..." ... />
Then you may need to specify something like
<CheckBoxPreference android:key="..." ... />
in the preference xml file. Setting should be android:widgetLayout to the custom CheckBox.
See this post may help you more customizing checkbox preference

No style ViewPagerIndicator in combination with SherlockActionBar

I'm trying to implement the ViewPagerIndicator with SherlockActionBar. It works: I can slide the fragments, but the style doesn't work!
It looks like this:
related topic: https://github.com/JakeWharton/Android-ViewPagerIndicator/issues/66
I know what's going wrong:
In the sample of VPI, the style of a page is set in AndroidManifest.xml by (for example)
<activity
android:name=".SampleTabsDefault"
android:theme="#style/Theme.PageIndicatorDefaults">
</activity>
But when I add that android:theme element to my own Manifest.xml I get the following exception:
03-16 11:06:24.400: E/AndroidRuntime(483): Caused by: java.lang.IllegalStateException: You must use Theme.Sherlock, Theme.Sherlock.Light, Theme.Sherlock.Light.DarkActionBar, or a derivative.
I've also tried to copy all the style-information to styles.xml, but that also doesn't work.
Can you tell me how to set a style to the VPI?
Thank you!
EDIT:
Now I've added
<activity
android:name=".SampleTabsDefault"
android:theme="#style/StyledIndicators">
</activity>
to my Manifest.xml
and the following style in styles.xml
<style name="Theme.BataApp" parent="Theme.Sherlock.Light.DarkActionBar">
<item name="actionBarStyle">#style/Widget.Styled.ActionBar</item>
<item name="android:actionBarStyle">#style/Widget.Styled.ActionBar</item>
</style>
<style name="StyledIndicators" parent="Theme.BataApp">
<item name="vpiTitlePageIndicatorStyle">#style/Widget.TitlePageIndicator</item>
<item name="vpiTabPageIndicatorStyle">#style/Widget.TabPageIndicator</item>
<item name="vpiTabTextStyle">#style/Widget.TabPageIndicator.Text</item>
</style>
Result: I don't get any Exception, see the style, but I now I can't see any fragments :(
The code of the activity can be found here: http://pastebin.com/hsNgxFDZ
Screenshot of current page with style:

In order to see the Fragments, you'll have to somehow extend an Android base-theme. In order to see the ViewPagerIndicator, you'll have to somehow include those style-definitions. The answer is to create your own theme that extends the ActionBarSherlock-theme (which extends the Android base-themes), and implements the ViewPagerIndicator-styles.
Example:
<style name="myTheme" parent="#style/Theme.Sherlock">
<!-- If you want to use the default ViewPagerIndicator-styles, use the following: -->
<item name="vpiTitlePageIndicatorStyle">#style/Widget.TitlePageIndicator</item>
<item name="vpiTabPageIndicatorStyle">#style/Widget.TabPageIndicator</item>
<item name="vpiTabTextStyle">#style/Widget.TabPageIndicator.Text</item>
<!-- If you want to implement your custom style of CirclePageIndicator, do it like so: -->
<item name="vpiCirclePageIndicatorStyle">#style/myCirclePageIndicator</item>
<!-- Put whatever other styles you want to define in your custom theme -->
</style>
<style name="myCirclePageIndicator" parent="Widget.CirclePageIndicator">
<item name="fillColor">#color/my_custom_circle_indicator_fill_color</item>
</style>
Then in your Manifest, set android:theme="#style/myTheme" to the <application> or to your <activity>s.
Note that you don't have to include all 4 "vpi..."-styles; you only have to include those that you use. E.g. if you're only using the CirclePageIndicator, you only have to include <item name="vpiCirclePageIndicatorStyle">...</item> and can leave out the other 3 item declarations.

I accidentally removed android:layout_weight="1" when adding styles.
So for other who want to implement VPI with ABS:
layout.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.viewpagerindicator.TabPageIndicator
android:id="#+id/indicator"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
style="#style/StyledIndicators" />
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
/>
</LinearLayout>
styles.xml:
<style name="Theme.BataApp" parent="Theme.Sherlock.Light.DarkActionBar">
etc.
</style>
<style name="StyledIndicators" parent="Theme.BataApp">
<item name="vpiTitlePageIndicatorStyle">#style/Widget.TitlePageIndicator</item>
<item name="vpiTabPageIndicatorStyle">#style/Widget.TabPageIndicator</item>
<item name="vpiTabTextStyle">#style/Widget.TabPageIndicator.Text</item>
</style>
Thank you #Reinier! :D
