Android Basic Controls Togglebutton&switch use guide _android

ToggleButton (switch button) and switch (switches) to explain:

First, the core attribute explanation:

(1) ToggleButton

Texton: Text display when the button is selected

Textoff: Text display when the button is not selected

The status of the ToggleButton can only be checked and unchecked, and different display text needs to be set for different states.

The following case is the use of ToggleButton

Directory structure

Main.xml Layout file

<?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" >
  <imageview android:id= "@+id/imageview" android:layout_width= "Wrap_content"
    android:layout_height= "wrap_content"
    android:src= "@drawable/bulb_off" 
    android:layout_gravity= " Center_horizontal "/>
  <togglebutton android:id=" @+id/togglebutton "
    android:layout_width=" 140dip "
    android:layout_height= "wrap_content"
    android:texton= "turn on the Lights"
    android:textoff= "Turn Off the Lights"
    android: layout_gravity= "Center_horizontal"/>
</LinearLayout>

Togglebuttonactivity class

Package COM.LJQ.TB;
Import android.app.Activity;
Import Android.os.Bundle;
Import Android.widget.CompoundButton;
Import Android.widget.ImageView;
Import Android.widget.ToggleButton;

Import Android.widget.CompoundButton.OnCheckedChangeListener;
  public class Togglebuttonactivity extends activity {private ImageView imageview=null;
  
  Private ToggleButton Togglebutton=null;
    @Override public void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);
    
    Setcontentview (R.layout.main);
    imageview= (ImageView) Findviewbyid (R.id.imageview);
    togglebutton= (ToggleButton) Findviewbyid (R.id.togglebutton);  Togglebutton.setoncheckedchangelistener (New Oncheckedchangelistener () {public void oncheckedchanged (CompoundButton
        Buttonview, Boolean ischecked) {togglebutton.setchecked (ischecked); Imageview.setimageresource (ischecked?)
      R.drawable.bulb_on:r.drawable.bulb_off);
  }
      
    }); }
}

Operation Effect:

(2) Switch:

Showtext: Set Texton/off When the text is displayed

Android:showtext: Whether to display text when On/off is set, Boolean

Android:splittrack: Whether to set a gap, let the slider and the bottom of the picture separated, Boolean

Android:switchminwidth: Set the minimum width of the switch

Android:switchpadding: Sets the spacing of text within the slider

Android:textoff: Text displayed when the button is not selected

Android:texton: Text displayed when the button is selected

Android:textstyle: Text style, bold, italic underline those

Android:track: Bottom of the picture

Android:thumb: Picture of the slider

You can try every single one of these properties.

When making a Bluetooth switch, use the switch, remember the usage, in fact, and button is almost the same.

In Layout:

<switch 
    android:id= "@+id/open" 
    android:layout_width= wrap_content "android:layout_height=" Wrap_ 
    Content " 
    android:textoff=" Bluetooth off 
    

In Java code

Open.setoncheckedchangelistener (New Oncheckedchangelistener () { 
 
      @Override public 
      void OnCheckedChanged ( Compoundbutton Buttonview, 
          boolean ischecked) { 
        //TODO auto-generated method Stub 
        if (ischecked) { 
          Mbluetoothadapter.enable ();//Open Bluetooth 
        } else { 
          mbluetoothadapter.disable ();//Close Bluetooth}}} 
    ); 

That's it, I see it.
