Android Label Control

Version: 1.0Date: 2014.7.24 Copyright: © kince Reprint Annotated source in some applications may need to set some tags to facilitate the use of some information, such as mobile phone assistants or shopping software will have some tags. For the early stage of software development, direct use of textview, button implementation is the simplest way. But this method also has its limitations, such as the inability to control the line-wrapping, low coupling disadvantage.  Therefore, in addition to solving these problems, it is better to encapsulate a class library out, convenient for later use. First create a new tag class,

Import Java.io.serializable;public class Tag implements Serializable {/** * */private static FI           nal long serialversionuid = 2684657309332033242L;      private int backgroundresid;      private int id;      Private Boolean isChecked;      private int leftdrawableresid;      private int rightdrawableresid;      Private String title;           Public tag () {} public tag (int paramint, String paramstring) {this. id = paramint;     this. title = Paramstring;     } public int Getbackgroundresid () {return this. backgroundresid;     } public int getId () {return this. id;     } public int Getleftdrawableresid () {return this. leftdrawableresid;     } public int Getrightdrawableresid () {return this. rightdrawableresid;     } public String GetTitle () {return this. title;   } public boolean isChecked () {return this. isChecked;  } public void Setbackgroundresid (int paramint) {this. backgroundresid = Paramint;     The public void setchecked (Boolean Paramboolean) {this. isChecked = Paramboolean;     } public void SetId (int. paramint) {this. id = paramint;     } public void Setleftdrawableresid (int paramint) {this. leftdrawableresid = Paramint;     } public void Setrightdrawableresid (int paramint) {this. rightdrawableresid = Paramint;     public void Settitle (String paramstring) {this. title = Paramstring; }}

  This class encapsulates the background image resource, ID, check, and so on for the label view.   then new Tagview class, inherited from ToggleButton,

Import Com.niceapp.lib.tagview.r;import Android.content.context;import Android.util.attributeset;import      Android.widget.togglebutton;public class Tagview extends ToggleButton {private Boolean mcheckenable = true;          Public Tagview (Context paramcontext) {super (Paramcontext);     Init (); } public Tagview (Context paramcontext, AttributeSet paramattributeset) {super (Paramcontext, paramattribut          ESet);     Init (); } public Tagview (Context paramcontext, attributeset paramattributeset, int paramint) {Super          (Paramcontext, Paramattributeset, 0);     Init ();          } private void Init () {Settexton (null);          Settextoff (NULL);          SetText ("");     Setbackgroundresource (r.drawable. TAG_BG);           The public void Setcheckenable (Boolean Paramboolean) {this. mcheckenable = Paramboolean; if (!this. mcheckenable) {super. Setchecked (FALSE);          }} public void Setchecked (Boolean Paramboolean) {if (this. mcheckenable) {          Super. Setchecked (Paramboolean); }     }}

This tagview is the tag view, and the tag information is displayed by him. The corresponding XML file is as follows, Tag.xml:

<? XML version= "1.0" encoding = "Utf-8"?>< com.niceapp.lib.tagview.widget.TagView xmlns:android = "http// Schemas.android.com/apk/res/android "    android:layout_width=" wrap_content "    android:layout_height=" Wrap_ Content "    android:drawablepadding=" 5.0dip "    android:minheight=" 0.0dip "    android:paddingbottom=" 4.5dip "    android:paddingleft=" 20.0dip "    android:paddingright=" 20.0dip "    android:paddingtop=" 4.5dip    " Android:textcolor= "#ff000000"    android:textsize= "16.0sp"/>

shown below:On GitHub there's aAndroid-flowlayoutcontrol, which dynamically wraps the view according to the size of the child view,
 As a result, control of line breaks can be implemented using this control without having to reinvent the wheel. The class implemented by the Android-flowlayout feature is FlowLayout, so the implementation of the label control is accomplished by inheriting the class.

  The most desired part of this class is the Inflatetagview method, which parses the Tagview out and then displays the label Taglistview to be displayed. The code for the   last activity is as follows:

Import Java.util.arraylist;import Java.util.list;import Com.niceapp.lib.tagview.widget.tag;import Com.niceapp.lib.tagview.widget.taglistview;import Android.app.activity;import Android.os.Bundle;public Class     Mainactivity extends Activity {private Taglistview mtaglistview;     Private final list<tag> mtags = new arraylist<tag> (); Private final string[] titles = {"Security essentials", "Music", "Parents Learn", "office worker Essentials", " Mobile Defender", "QQ", "Input Method", "", "most Beautiful Application", "Andevui     "," Mushroom Street "};          @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);          Setcontentview (r.layout.select_tag_activity);          Mtaglistview = (Taglistview) Findviewbyid (R.id.tagview);          SetupData ();     Mtaglistview.settags (Mtags);               private void SetupData () {for (int i = 0; i <; i++) {tag tag = new Tag ();               Tag.setid (i);               Tag.setchecked (TRUE); Tag.settitle (Titles[i]);              Mtags.add (tag); }     }}

The real-computer display works as follows:Of course, the appearance of this tagview can be set on its own, including fonts, backgrounds and so on. Project code: http://download.csdn.net/detail/wangjinyu501/7673827
