Android simpleadapter displays listview and gridview

Simpleadapter, as a dataset, mainly fills the listview and gridview containers with data and summarizes several filling methods. The principle is very simple. You can directly look at the code and

1. Single Row display of listview(Simple_list_item_1)

Code:

Public class mylistitem1 extends activity {<br/> @ override <br/> Public void oncreate (bundle savedinstancestate) {<br/> super. oncreate (savedinstancestate); </P> <p> listview = new listview (this); </P> <p> List <Map <string, string> MList = new arraylist <Map <string, string> (); <br/> for (INT I = 0; I <10; I ++) {<br/> Map <string, string> map = new hashmap <string, string> (); <br/> map. put ("title", "test title"); <br/> map. put ("content", "Test content"); <br/> MList. add (MAP); <br/>}</P> <p> simpleadapter adapter = new simpleadapter (this, <br/> MList, <br/> android. r. layout. simple_list_item_1, // list display a row of Item1 <br/> New String [] {"content"}, // "title", <br/> New int [] {android. r. id. text1} <br/>); </P> <p> listview. setadapter (adapter); <br/> setcontentview (listview); <br/>}< br/>}

Effect:

2. listview dual-row display(Simple_list_item_2)

Code:

Public class mylistitem2 extends activity {<br/> @ override <br/> Public void oncreate (bundle savedinstancestate) {<br/> super. oncreate (savedinstancestate); </P> <p> listview = new listview (this); </P> <p> List <Map <string, string> MList = new arraylist <Map <string, string> (); <br/> for (INT I = 0; I <10; I ++) {<br/> Map <string, string> map = new hashmap <string, string> (); <br/> map. put ("title", "test title"); <br/> map. put ("content", "Test content"); <br/> MList. add (MAP); <br/>}</P> <p> simpleadapter adapter = new simpleadapter (this, <br/> MList, <br/> android. r. layout. simple_list_item_2, // list display Item1, item2 <br/> New String [] {"title", "content"}, <br/> New int [] {android. r. id. text1, android. r. id. text2} <br/>); </P> <p> listview. setadapter (adapter); <br/> setcontentview (listview); <br/>}< br/>}

Effect:

3. Custom display of listview

Code:

Public class mylist extends activity {<br/> @ override <br/> Public void oncreate (bundle savedinstancestate) {<br/> super. oncreate (savedinstancestate); <br/> setcontentview (R. layout. mylist); </P> <p> List <Map <string, Object> MList = new arraylist <Map <string, Object> (); <br/> for (INT I = 0; I <10; I ++) {<br/> Map <string, Object> map = new hashmap <string, object> (); <br/> map. put ("pic", R. drawable. PIC); // load image resources <br/> map. put ("title", "test title"); <br/> map. put ("content", "Test content"); <br/> MList. add (MAP); <br/>}</P> <p> simpleadapter adapter = new simpleadapter (this, <br/> MList, <br/> r. layout. listitem, // custom Layout format <br/> New String [] {"pic", "title", "content "}, <br/> New int [] {R. id. listitem_pic, R. id. listitem_title, R. id. listitem_content }< br/>); </P> <p> listview = (listview) findviewbyid (R. id. list); <br/> listview. setadapter (adapter); <br/>}< br/>}Custom listitem. xml

<? XML version = "1.0" encoding = "UTF-8"?> </P> <p> <relativelayout xmlns: Android = "http://schemas.android.com/apk/res/android" <br/> Android: layout_width = "fill_parent" <br/> Android: layout_height = "? Android: ATTR/listpreferreditemheight "> </P> <p> <imageview Android: Id =" @ + ID/listitem_pic "<br/> Android: layout_width = "wrap_content" <br/> Android: layout_height = "fill_parent" <br/> Android: layout_alignparenttop = "true" <br/> Android: layout_alignparentbottom = "true" <br/> Android: adjustviewbounds = "true" <br/> Android: padding = "10dip"/> </P> <p> <textview Android: id = "@ + ID/listitem_title" <br/> Android: layout_width = "wrap_content" <br/> Android: layout_height = "wrap_content" <br/> Android: layout_torightof = "@ ID/listitem_pic" <br/> Android: layout_alignparentright = "true" <br/> Android: layout_alignparenttop = "true" <br/> Android: layout_alignwithparentifmissing = "true" <br/> Android: gravity = "center_vertical" <br/> Android: textsize = "22sp"/> </P> <p> <textview Android: id = "@ + ID/listitem_content" <br/> Android: layout_width = "fill_parent" <br/> Android: layout_height = "wrap_content" <br/> Android: layout_torightof = "@ ID/listitem_pic" <br/> Android: layout_alignparentbottom = "true" <br/> Android: layout_alignparentright = "true" <br/> Android: layout_below = "@ ID/listitem_title" <br/> Android: singleline = "true" <br/> Android: ellipsize = "marquee" <br/> Android: textsize = "14sp"/> <br/> </relativelayout>

4. Custom display of gridview

Code:

Public class mygrid extends activity {<br/> @ override <br/> Public void oncreate (bundle savedinstancestate) {<br/> super. oncreate (savedinstancestate); <br/> setcontentview (R. layout. mygrid); </P> <p> List <Map <string, Object> MList = new arraylist <Map <string, Object> (); <br/> for (INT I = 0; I <10; I ++) {<br/> Map <string, Object> map = new hashmap <string, object> (); <br/> map. put ("pic", R. drawable. PIC); // load image resources <br/> map. put ("title", "test title"); <br/> MList. add (MAP); <br/>}< br/> simpleadapter adapter = new simpleadapter (this, <br/> MList, R. layout. griditem, // custom Layout format <br/> New String [] {"pic", "title" },< br/> New int [] {R. id. griditem_pic, R. id. griditem_title ,}< br/>); </P> <p> gridview = (gridview) findviewbyid (R. id. grid); <br/> gridview. setadapter (adapter); <br/>}< br/>}Custom gridview. xml
<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <linearlayout xmlns: Android = "http://schemas.android.com/apk/res/android" <br/> Android: layout_height = "fill_parent" <br/> Android: layout_width = "fill_parent" <br/> Android: Orientation = "vertical"> </P> <p> <imageview Android: id = "@ + ID/griditem_pic" <br/> Android: layout_width = "wrap_content" <br/> Android: layout_height = "wrap_content" <br/> Android: layout_gravity = "center_horizontal"> <br/> </imageview> </P> <p> <textview Android: Id = "@ + ID/griditem_title" <br/> Android: layout_width = "wrap_content" <br/> Android: layout_height = "wrap_content" <br/> Android: layout_gravity = "center_horizontal"> <br/> </textview> <br/> </linearlayout>
