Android Custom Switch

I'm trying to make a custom switch like this:
with these properites:
text on both sides always shown.
different colors for on and off.
and these are two problems I faced since the switch only shows the text on the chosen side , and I can't seem to find a place where I can specify two different colors?
can I achieve this using the regular switch in android studio or must I use some library?
Thank you.

After researching I found a way that gives me exactly what I needed, this is what I got:
in case of anyone looking for a way to do it, this is how:
based on this post answer , which worked great for me.
this is what I did, I created two drawables one for On and another for Off :
switch_on.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:state_checked="true" android:drawable="#color/colorGray"/>
<item android:drawable="#color/colorPrimary" android:state_checked="true" />
<item android:drawable="#color/colorPrimaryDark" android:state_pressed="true" />
<item android:drawable="#color/transparent" />
</selector>
switch_off.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:state_checked="true" android:drawable="#color/colorGray"/>
<item android:drawable="#color/gray_light" android:state_checked="true" />
<item android:drawable="#color/black_overlay" android:state_pressed="true" />
<item android:drawable="#color/transparent" />
</selector>
Next , created a drawable for the outline of the switch.
outline.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="2dp" />
<solid android:color="#80ffffff" />
<stroke
android:width="1dp"
android:color="#color/gray_light" />
</shape>
one thing that I added is a drawable for the text color, because the color of the text changes depending on whether it's checked or not, this is it :
switch_text.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#color/colorWhite"/>
<item android:state_checked="true" android:color="#color/colorWhite"/>
<item android:color="#color/gray_light"/>
</selector>
and finally, created RadioGroup in my layout this way:
<RadioGroup
android:id="#+id/toggle"
android:layout_width="wrap_content"
android:layout_height="50dp"
android:background="#drawable/outline"
android:checkedButton="#+id/off"
android:orientation="horizontal">
<RadioButton
android:id="#+id/off"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginBottom="1dp"
android:layout_marginStart="1dp"
android:layout_marginTop="1dp"
android:layout_weight="1"
android:background="#drawable/switch_off"
android:button="#null"
android:gravity="center"
android:padding="#dimen/fab_margin"
android:text="#string/off"
android:textColor="#drawable/switch_text" />
<RadioButton
android:id="#+id/on"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginBottom="1dp"
android:layout_marginEnd="1dp"
android:layout_marginTop="1dp"
android:layout_weight="1"
android:background="#drawable/switch_on"
android:button="#null"
android:gravity="center"
android:padding="#dimen/fab_margin"
android:text="#string/on"
android:textColor="#drawable/switch_text" />
</RadioGroup>
Notice the usage of each drawable in the right place:
android:background="#drawable/outline" for the RadioGroup
android:background="#drawable/switch_off" for the first RadioButton
android:background="#drawable/switch_on" for the second RadioButton
android:textColor="#drawable/switch_text" for both Radio Buttons
And that's all.

Use ToggleButton(change height/width as per image ratio) & selector, here's the code
<ToggleButton
android:id="#+id/toggle_"
android:layout_width="60dp"
android:layout_height="30dp"
android:layout_alignParentStart="true"
android:background="#drawable/on_off"
android:textOff=""
android:textOn=""/>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true"
android:drawable="#drawable/ic_on" />
<item android:state_checked="false"
android:drawable="#drawable/ic_off" />
</selector>

To create ON and OFF labels for the switch you can use the attributes android:textOn and android:textOff with the switch declaration.
To ensure, that the text lebals are always displayed, especially for API Level bigger API21, also use this attribute: android:showText="true".
Then your switch should look like this:
<Switch
android:id="#+id/switcher"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOff="OFF"
android:textOn="ON"
android:showText="true"
/>
In order to change the default color, you have to specify a seperate design for it like that:
1. In file values\styles.xml define a style like that:
<style name="CustomSwitchTheme" parent="Theme.AppCompat.Light">
<item name="android:colorControlActivated">#FF0000</item>
</style>
It is important, that you also reference the correct parent theme.
2. After defining the new switch style, you can link your custom style to the switch with the attribute
android:theme="#style/CustomSwitchTheme"
Finally your Switch should look like that:
<Switch
android:id="#+id/switcher"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOff="OFF"
android:textOn="ON"
android:showText="true"
android:theme="#style/CustomSwitchTheme"
/>

Android: how to use selector?

I have a problem of using selector that it does not work as what I expect. I wanna click on it then it gives me reaction and I select it(By long click but I probably do it through programmatic way) then it gives me another reaction. However, it reacts nothing in result....
reaction part:
<TableRow
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="10"
android:padding="5dp"
android:background="#drawable/border_bottom"
>
<LinearLayout
android:layout_weight="9"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#drawable/selector_row">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#color/grey"
android:text="#string/tel"/>
<TextView
android:id="#+id/telText"
android:layout_width="wrap_content"
android:textSize="18sp"
android:layout_height="wrap_content"
android:text="#string/blank"/>
</LinearLayout>
<ImageButton
android:layout_weight="1"
android:id="#+id/tel_call"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:src="#drawable/ic_action_call"
android:background="#drawable/border_left"/>
</TableRow>
selector_row.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:state_pressed="true"
android:drawable="#color/semitransparent_grey"></item>
<item
android:state_selected="true"
android:drawable="#color/semitransparent_blue"></item>
<item
android:drawable="#color/transparent"></item>
</selector>

Thank you to all brothers trying hard to answer me. I have got the answer....just simply by setting android:clickable="true" at LinearLayout. Ha, it's silly.....
I remember dude who provide relating information but I ignored... sorry to him.

Create an XML file and place it in the drawable folder. Open it and write the following code:
<selector
xmlns:android="http://schemas.android.com/apk/res/android"
>
<item
android:drawable="YOUR IMAGE OR COLOR"
android:state_pressed="true"/>
<item
android:drawable="YOUR IMAGE OR COLOR"
android:state_selected="true"/>
<item
android:drawable="YOUR IMAGE OR COLOR"
android:state_focused="true"/>
</selector>
Then in your main XML file, place android:background="#drawable/selector.xml"

What are you expecting? A reaction only when it's clicked?
Try removing removing:
android:state_selected="true"
Edit:
This should be your selector:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/my_drawable" android:state_selected="true"></item>
<item android:drawable="#drawable/my_drawable" android:state_pressed="true"></item>
<item android:drawable="#drawable/my_drawable"></item>
</selector>
What is the behaviour that you are experiencing?
Edit:
<LinearLayout
android:layout_weight="9"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#drawable/selector_row"
android:duplicateParentState=true>
I don't know if it actually solves the problem

Images not Switching in Android Custom Toggle Button

In my android application, I am trying to make a simple toggle button switching between two images, actually a star to mark as favorites. States of the button are being changed but images are not switching for ON and OFF states. Image of the OFF state is being displayed by default continuously.
I have tried the following tutorials:
http://www.coderzheaven.com/2012/05/20/create-custom-toggle-button-android/
http://www.technotalkative.com/android-custom-toggle-button-example/
** togbtn_fav_custom.xml **
<item android:drawable="#drawable/ic_action_important" android:state_checked="true" android:state_pressed="true"/>
<item android:drawable="#drawable/ic_action_important" android:state_checked="true" android:state_focused="false"/>
<item android:drawable="#drawable/ic_action_not_important" android:state_checked="false" android:state_pressed="true"/>
<item android:drawable="#drawable/ic_action_not_important" android:state_checked="false" android:state_focused="false"/>
layout.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<LinearLayout
android:id="#+id/ll_back_single_dua_footer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical" >
<Button
android:id="#+id/btn_play_pause_dua"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:background="#drawable/play_btn_custom" />
<TextView
android:id="#+id/tv_back_single_dua_footer_counter"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center_horizontal"
android:singleLine="true"
android:text="#string/sample_counter"
android:textSize="23sp" />
<ToggleButton
android:id="#+id/tog_btn_favorite_dua"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/togbtn_fav_custom"
android:textOff=""
android:textOn=""
/>
</LinearLayout>
</LinearLayout>
Can anybody please guide me what am I missing?

Try to simplify your selector.xml like this:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/ic_action_not_important" android:state_checked="false"/>
<item android:drawable="#drawable/ic_action_important" android:state_checked="true"/>
</selector>
And as Achilles said, check line
android:background="#drawable/togbtn_fav_custom"
May be you need to set selector.xml as background?

How to work with Selector Listview in Android?

I have file lst_custom_view.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top|left"
android:background="#drawable/list_choose"
android:orientation="horizontal">
<TextView
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_gravity="center"
android:layout_marginLeft="20dp"
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:singleLine="true"
android:textColor="#ff000000"
android:textSize="22dp" />
</RelativeLayout>
And Listview in Main.xml
<ListView
android:id="#+id/lstView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_weight="1"
android:background="#android:color/transparent"
android:cacheColorHint="#android:color/transparent"
android:divider="#drawable/menu_phancach"
android:dividerHeight="2dp"
android:visibility="visible">
</ListView>
I use Selector with Background of Relativelayout with name list_choose.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_selected="false"
android:state_pressed="false"
android:drawable="#drawable/menu_content" />
<item android:state_selected="true"
android:state_pressed="false"
android:drawable="#drawable/menu_content_hover" />
<item android:state_pressed="true"
android:drawable="#drawable/menu_content_hover" />
</selector>
it's show me the background of RelativeLayout menu_content_hover when i Press on items listview, but not selected with background menu_content_hover. I want it change background menu_content_hover when user press on items and selected ,change backround menu_content when user scroll list(unselected) or choose another items.I used simpleCursorAdapter. Any Help? Thanks for all your help.

The selector should be like this:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="#drawable/background_pressed" />
<item android:state_focused="true"
android:drawable="#drawable/background_focused" />
<item android:state_selected="true"
android:drawable="#drawable/background_selected" />
<item android:drawable="#drawable/background_default"/>
</selector>

Change ListView's text color on click

I have a customized ListView that each row of the list is composed by an ImageView and two TextView's. I want to change the text's color to white when a list's item is clicked (only in the clicked item). Also, I want to change back the color to black when the item is "unclicked" (when the "press" is released). I already made the item's background color change when it was clicked with the following list_item_bg.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_selected="false"
android:state_pressed="false"
android:drawable="#color/white" />
<item android:state_pressed="true"
android:drawable="#color/red_destaques" />
<item android:state_selected="true"
android:drawable="#color/red_destaques" />
</selector>
And the listitem_row.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="50dip"
xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="5dip"
android:maxHeight="50dip"
android:adjustViewBounds="true"
android:background="#color/list_item_bg">
<ImageView
android:layout_width="70dip"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:adjustViewBounds="true"
android:scaleType="fitStart"
android:src="#drawable/imagem_padrao_lista"
android:id="#+id/listItemLogo">
</ImageView>
<TextView
android:textAppearance="?android:attr/textAppearanceLarge"
android:layout_height="wrap_content"
android:text="TextView"
android:layout_width="wrap_content"
android:layout_toRightOf="#+id/listItemLogo"
android:layout_toLeftOf="#+id/listItemArrow"
android:textColor="#000000"
android:layout_marginLeft="5dip"
android:adjustViewBounds="true"
android:id="#+id/listItemTitle">
</TextView>
<TextView
android:layout_height="wrap_content"
android:text="TextView"
android:layout_width="wrap_content"
android:layout_toRightOf="#+id/listItemLogo"
android:layout_below="#+id/listItemTitle"
android:textColor="#333333"
android:layout_marginLeft="5dip"
android:adjustViewBounds="true"
android:id="#+id/listItemDescription">
</TextView>
<ImageView android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_alignParentRight="true" android:src="#drawable/setinha_navegacao" android:layout_centerVertical="true" android:id="#+id/listItemArrow"></ImageView>
</RelativeLayout>
I the text to change it's color exactly in the same manner that the background changes as shown in the above xmls. I would prefer doing this change by code if possible...

Create a new StateListDrawable like you did before but with black as default color and white when pressed.
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true" android:color="#color/black" />
<item android:state_focused="true" android:color="#color/black" />
<item android:state_pressed="true" android:color="#color/black" />
<item android:color="#color/white" />
</selector>
Now for in the TextView change the text color to the new drawable:
android:textColor="#color/list_item_text"
