Using lambda expression and a Switch: public void onCheckedChanged(boolean checked) { // implementation } XML file: <android.support.v7.widget.SwitchCompat android:onCheckedChanged=”@{(switch, checked) -> item.onCheckedChanged(checked)}” … /> Where item is the class that implements onCheckedChange method and is imported to the XML file like this: <data> <variable name=”item” type=”yourClass”/> </data>
Call jumpDrawablesToCurrentState() to skip the animation switchCompat.setChecked(true); switchCompat.jumpDrawablesToCurrentState();
Text is not shown by default under Material theme since the switch widget assets don’t work well with text. Any text that you do set will be used to describe the content to accessibility services. You can change this using the android:showText property or Switch.setShowText(boolean) method. <Switch … android:showText=”true” /> If you are using AppCompat … Read more
Set the listener to null before calling setCheck() function, and enable it after that, such as the following: switch.setOnCheckedChangeListener (null); switch.setChecked(true); switch.setOnCheckedChangeListener (this); Reference: Change Checkbox value without triggering onCheckChanged
However, I might not be taking the best approach, but this is how I have created some Switch like UIs in few of my apps. Here is the code – <RadioGroup android:checkedButton=”@+id/offer” android:id=”@+id/toggle” android:layout_width=”match_parent” android:layout_height=”30dp” android:layout_marginBottom=”@dimen/margin_medium” android:layout_marginLeft=”50dp” android:layout_marginRight=”50dp” android:layout_marginTop=”@dimen/margin_medium” android:background=”@drawable/pink_out_line” android:orientation=”horizontal”> <RadioButton android:layout_marginTop=”1dp” android:layout_marginBottom=”1dp” android:layout_marginLeft=”1dp” android:id=”@+id/search” android:background=”@drawable/toggle_widget_background” android:layout_width=”0dp” android:layout_height=”match_parent” android:layout_weight=”1″ android:button=”@null” android:gravity=”center” android:text=”Search” android:textColor=”@color/white” /> … Read more
Using scale property to change size worked for me. Add these lines to your <switch/> tag in xml file. android:scaleX=”2″ android:scaleY=”2″ You can change scale value as per your need. Here value 2 makes it double in size, similarly value 0.5 makes it half in size. Example: <Switch android:id=”@+id/switchOnOff” android:layout_width=”wrap_content” android:layout_height=”wrap_content” android:scaleX=”2″ android:scaleY=”2″/>
It’s weird all of us have this problem but not official Google answer to this simple problem. The MOST simple it’s to check: buttonView.isPressed() If true, means the user clicked the view. No global variables are needed.
You can define the drawables that are used for the background, and the switcher part like this: <Switch android:layout_width=”wrap_content” android:layout_height=”wrap_content” android:thumb=”@drawable/switch_thumb” android:track=”@drawable/switch_bg” /> Now you need to create a selector that defines the different states for the switcher drawable. Here the copies from the Android sources: <selector xmlns:android=”http://schemas.android.com/apk/res/android”> <item android:state_enabled=”false” android:drawable=”@drawable/switch_thumb_disabled_holo_light” /> <item android:state_pressed=”true” android:drawable=”@drawable/switch_thumb_pressed_holo_light” … Read more
