Farewell spinner drop-down list, with Popupwindow better

============ Problem Description ============

The first post, mainly I today in order to achieve a good view of the drop-down list, on the internet to find a day about spinner information, did not see good posts. Try a variety of methods, always find how to set the background of the dropdown box method, if please give me a message, thank you.

Finally, in the great teacher's advice, I decided to change the direction to consider using his popupwindow, so I found a write down the sword, so I can't wait to share this to those who are as lost as I have little friends.
In this case, the Popupwindow can be clicked on the external area to cancel the view function.

<USES-SDK
android:minsdkversion= "14"
android:targetsdkversion= "/> "



Let's see it, it's simple.


Images used:




Here button picture inside of the arrow I do together, if you do not like, want the arrow button to become a button, you can change the main page of the layout file, TextView after adding a button, then set the background is good. Think spinner can do this? I don't want to throw up the groove.
Just fine.


Code: Activity Section

Popwindowspinneractivity.java

Package com.example.spinnertest;import java.util.arraylist;import android.app.activity;import  android.os.Bundle;import android.view.View;import android.widget.AdapterView;import  android.widget.listview;import android.widget.popupwindow;import android.widget.textview;/** *   This is a popwindow  implementation of the drop-down list, compared to spinner, I found spinner, simply useless.  *  @author  lishuai * */public class popwindowspinneractivity extends  activity {//drop-down button Textview mybutton;//popupwindow Object declaration popupwindow pw; arraylist<string> list;//the currently selected list item location int clickpsition = -1; @Overridepublic  void  oncreate (bundle savedinstancestate)  {super.oncreate (savedinstancestate); SetContentView ( R.layout.activity_pop_window); mybutton =  (TextView)  findviewbyid (R.id.mybutton);//Obtain the data to be displayed list = getlist ();// Sets the default display of Textmybutton.settext (list.get (0)); Mybutton.setonclicklistener (new View.onclicklistener ()  {@Overridepublic  void onclick (view v)  {//through the layout injector, Inject the layout to the View Object View myview = getlayoutinflater (). Inflate (r.layout.pop, null);//through view  and wide · High, tectonic Popopwindowpw = new popupwindow (myview, 240, 300, true); Pw.setbackgrounddrawable (Getresources (). Getdrawable (//here to set the background for popwindow , colleagues do click on the external area, Popwindow disappears R.DRAWABLE.DIAOLOG_BG));//Set the focus to clickable pw.setfocusable (true);//You can try the result set to False// The window view is displayed under MyButton pw.showasdropdown (MyButton); listview lv =  (ListView)  myview.findviewbyid (R.id.lv_pop); Lv.setadapter (new  Listviewadapter (popwindowspinneractivity.this, list)); Lv.setonitemclicklistener (new  Adapterview.onitemclicklistener ()  {@Overridepublic  void onitemclick (adapterview<?>  Parent, view view,int position, long id)  {mybutton.settext (list.get (position)); if  (clickpsition != position)  {clickpsition&nbsP;= position;} Pw.dismiss ();});}); /** *  How to get the list collection  *  @return  */public arraylist<string> getlist ()  {ArrayList<String> list = new ArrayList<String> (); List.add ("Daily Spit"); List.add ("Inspiration note"), List.add ("Comedy Wang Wen"), List.add ("Connotation Satin"), List.add ("Daily Spit"), List.add ("Inspiration note"), List.add ("Comedy Wang Wen"); List.add ("Connotation Satin"); List.add ("Daily Spit"); List.add ("Inspiration note"), List.add ("Comedy Wang Wen"), List.add ("connotation"); return list;}}

Next is the adapter: This is a small optimization of the next.
Listviewadapter.java

package com.example.spinnertest;import java.util.arraylist;import android.content.context; import android.view.layoutinflater;import android.view.view;import android.view.viewgroup; import android.widget.baseadapter;import android.widget.textview;/** *  Adapter  * @ author administrator * */public class listviewadapter extends baseadapter{ private layoutinflater inflater;private arraylist<string> list; public  Listviewadapter (context context, arraylist<string> list)  {super (); this.inflater  = layoutinflater.from (context); this.list = list;} @Overridepublic  int getcount ()  {return list.size ();} @Overridepublic  object getitem (int position)  {// todo auto-generated method  stubreturn null;} @Overridepublic  long getitemid (int position) &NBSP;{//&NBSP;TODO&NBSp auto-generated method stubreturn 0;} @Overridepublic  view getview (int position, view convertview, viewgroup  Parent)  {if  (convertview == null)  {convertview = inflater.inflate ( R.layout.lv_items, null);} textview tv =  (TextView) Convertview.findviewbyid (R.id.text); Tv.settext (List.get (position)); Return convertview;}}

Next is the Drawable folder inside the Click Effect selector:selector_sinner.xml

<?xml version= "1.0" encoding= "Utf-8"? ><selector xmlns:android= "http://schemas.android.com/apk/res/ Android "> <item android:drawable=" @drawable/spinner_bg_press "android:state_pressed=" true "/> <item Android oid:drawable= "@drawable/spinner_bg" android:state_pressed= "false"/></selector>

Then there are several XML files:

File name: Activity_pop_window.xml

<?xml version= "1.0"  encoding= "Utf-8"? ><linearlayout xmlns:android= "http// Schemas.android.com/apk/res/android "    android:layout_width=" Fill_parent "     android:layout_height= "Fill_parent"     android:background= "#fff"      android:orientation= "Vertical"  >    <TextView         android:paddingleft= "5DP"         android : id= "@+id/mybutton"         android:gravity= "center_vertical"          android:layout_width= "Wrap_content"          android:layout_height= "Wrap_content"         android: Layout_gravity= "Center_horizontal"         android:background= "@ Drawable/selector_sinner "   &nbSp;    android:textcolor= "#000"  /></LinearLayout> 

File name: Lv_items.xml

<?xml version= "1.0" encoding= "Utf-8"? ><linearlayout xmlns:android= "http://schemas.android.com/apk/res/ Android "Android:layout_width=" Match_parent "android:layout_height=" match_parent "android:orientation=" vertical " > <textview android:layout_marginleft= "20dp" android:id= "@+id/text" android:layout_width= "WR Ap_content "android:layout_height=" wrap_content "android:textcolor=" #000 "/></linearlayout>

File name: Pop.xml

<?xml version= "1.0" encoding= "Utf-8"? ><linearlayout xmlns:android= "http://schemas.android.com/apk/res/    Android "Android:layout_width=" Match_parent "android:layout_height=" match_parent "android:orientation=" vertical "        android:paddingtop= "60DP" > <listview android:id= "@+id/lv_pop" android:divider= "@color/line" Android:layout_width= "Match_parent" android:layout_height= "Match_parent"/></linearlayout>

After studying Android for a year, I used Popupwindow for the first time today and found it so powerful. Really ashamed ... No more nonsense.
Everybody cheer up.

The idea of such a bull B must have been taught by the old Bell.
