Android Custom View (vii)------custom controls combining faux Actionbar controls

We've written a sample of 6 custom view in front of us, all new self-drawn controls. In this example, let's combine several existing controls into a new control.

：

We use two buttons and a textview combination to become a actionbar, the following first one:

Key code: (1) res/layout/custom_action_bar.xml----Combo Control layout file

<relativelayout xmlns:android= "http://schemas.android.com/apk/res/android" xmlns:tools= "http// Schemas.android.com/tools "android:layout_width=" match_parent "android:layout_height=" Wrap_content "> < Button android:id= "@+id/button_ok" android:layout_width= "wrap_content" android:layout_height= "Wrap_co         Ntent "android:background=" @drawable/button_ok_click "android:layout_alignparentleft=" true "/> <TextView        Android:id= "@+id/title" android:layout_width= "wrap_content" android:layout_height= "Wrap_content" Android:layout_centerinparent= "true" android:visibility= "Gone"/> <button android:id= "@+ Id/button_no "android:layout_width=" wrap_content "android:layout_height=" Wrap_content "android:backgr ound= "@drawable/button_no_click" android:layout_alignparentright= "true"/></relativelayout>

(2) Customactionbar.java------Custom Combo Controls

Import Android.content.context;import Android.util.attributeset;import Android.view.layoutinflater;import Android.view.view;import Android.widget.button;import Android.widget.relativelayout;import Android.widget.textview;public class Customactionbar extends relativelayout{private button button_ok;private button Button_no;private TextView title;private actionbarclickedlistener actionbarclickedlistener;public CustomActionbar (    Context context) {This (context, NULL);    } public Customactionbar (context context, AttributeSet Attrs) {This (context, attrs, 0);        } public Customactionbar (context context, AttributeSet attrs, int defstyle) {Super (context, attrs, Defstyle);    Layoutinflater.from (context). Inflate (R.layout.custom_action_bar, this, true);        } protected void Onfinishinflate () {super.onfinishinflate ();        BUTTON_OK = (Button) Findviewbyid (R.ID.BUTTON_OK); Button_ok.setonclicklistener (New Onclicklistener () {@Overridepublic voidOnClick (view view) {//TODO auto-generated Method stub if (Actionbarclickedlistener! = null) {Actionbarclickedlistener.                Onactionbarokclicked ();        }}});        Button_no = (Button) Findviewbyid (r.id.button_no); Button_no.setonclicklistener (New Onclicklistener () {@Overridepublic void OnClick (view view) {//TODO auto-generated                Method stub if (Actionbarclickedlistener! = null) {actionbarclickedlistener.onactionbarcancelclicked ();                }}});    title = (TextView) Findviewbyid (r.id.title);    } public void Settitle (int resId) {title.settext (resId);    Title.setvisibility (view.visible); } public void Setactionbarclickedlistener (Actionbarclickedlistener actionbarclickedlistener) {this.actionbarClicked    Listener = Actionbarclickedlistener;        } public interface Actionbarclickedlistener {public void onactionbarokclicked ();    public void onactionbarcancelclicked (); }}

(3) res/layout/activity_main.xml-------Master File layout file

<relativelayout xmlns:android= "Http://schemas.android.com/apk/res/android"
Xmlns:tools= "Http://schemas.android.com/tools"
Android:layout_width= "Match_parent"
android:layout_height= "Wrap_content" >

<com.example.customviewactionbar.customactionbar
Android:id= "@+id/customactionbar"
Android:layout_width= "Match_parent"
android:layout_height= "Wrap_content"/>
</RelativeLayout>

(4) Mainactivity.java-----Main File

Import Com.example.customviewactionbar.customactionbar.actionbarclickedlistener;import Android.os.Bundle;import Android.app.activity;import Android.util.log;public class Mainactivity extends Activity implements Actionbarclickedlistener{public static final String TAG = "Customactionbar";p rivate customactionbar customactionbar;@ overrideprotected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview ( R.layout.activity_main); init ();} private void Init () {//TODO auto-generated method Stubcustomactionbar = (Customactionbar) Findviewbyid ( R.id.customactionbar); Customactionbar.setactionbarclickedlistener (this);//customactionbar.settitle ( Getresources (). GetText (R.string.hello_world)); Customactionbar.settitle (R.string.hello_world);} @Overridepublic void onactionbarokclicked () {//TODO auto-generated method stublog.i (TAG, "CLICK_OK");} @Overridepublic void onactionbarcancelclicked () {//TODO auto-generated method stublog.i (TAG, "Click_cancel"); Finish () ;}}

Custom view summary for a composite control:

1. Customize the combo control to get the control you want

2. Custom control, import layout file, implement self-desired control

3. Use in other layout files
