Android Custom Switch

Question

I'm trying to make a custom switch like this:

with these properites:

1. text on both sides always shown.
2. 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.

Answer 1

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.

Answer 2

i think this library can help you

implementation 'com.github.angads25:toggle:1.0.0'

Usage

1. Start by adding a Switch (eg. LabeledSwitch) in your xml layout as:

   <com.github.angads25.toggle.LabeledSwitch
       android:id="@+id/switch4"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_margin="16dp"
       android:textSize="14sp"
       app:on="false"
       app:textOn="ON"
       app:textOff="OFF"
       app:colorOn="#00c4a6"
       app:colorBorder="#00c4a6"/>
   

2. To the reference of Switch in your Activity/Fragment class set a Toggle Event Handler to it as below:

   LabeledSwitch labeledSwitch = findViewById(R.id.switch);
   labeledSwitch.setOnToggledListener(new OnToggledListener() {
       @Override
       public void onSwitched(LabeledSwitch labeledSwitch, boolean isOn) {
       // Implement your switching logic here
       }
   });
   

That's It. All your switching callbacks would be handled in onSwitched method, parameter isOn will provide the current state of the switch.
