Android Control ToggleButton (Multi-Status button)

I. Overview

ToggleButton has two states: checked and unchecked (similar to a switch), and you need to set different display text for different states

Second, ToggleButton properties

android:checked = "true"--the State of the button (True is checked (Texton), False is unchecked (Textoff))

Android:textoff = "Off"

Android:texton = "Open"

Three, the code demonstration

1, first put the following two pictures into the resource file (named off and on)

　　　　　　

<LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Android:layout_width= "Fill_parent"Android:layout_height= "Fill_parent"android:orientation= "vertical" >    <ToggleButtonAndroid:id= "@+id/togglebutton1"Android:layout_width= "Match_parent"Android:layout_height= "Wrap_content"Android:texton= "Open"Android:textoff= "Off" />    <ImageViewAndroid:id= "@+id/imageview1"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent"android:src= "@drawable/off" />    </LinearLayout>
