Android tag Control

Android tag Control
Version: 1.0 Date: Copyright:©2014 some tags may need to be set in some applications to facilitate the query of certain information, such as mobile assistant or shopping software. In the early stage of software development, using TextView and Button is the simplest method. However, this method also has its own limitations, such as the inability to control line breaks and low coupling. In addition to solving these problems, it is best to encapsulate a class library for future use. First, create a Tag class,

import java.io.Serializable;public class Tag implements Serializable {           /**      *      */      private static final 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;     }      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, and check of the label view. Create a new TagView class and inherit 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, paramAttributeSet);          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 );     }      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 label view, which displays the label information. The corresponding xml file is as follows, tag. xml:

 < 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" />

Display: There is an android-flowlayout control on github, which dynamically wraps the view based on the size of the subview,
Therefore, you can use this control to control the line feed without repeatedly inventing the wheel. The class implemented by the android-flowlayout function is FlowLayout. Therefore, the label control is implemented by inheriting this class.

The most important part of this class is the inflateTagView method. It parses the TagView and displays the tag to be displayed in the TagListView. 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
 
  
MTags = new ArrayList
  
   
(); Private final String [] titles = {"Security Essentials", "Music", "parents", "essential for office workers", "360 mobile guard", "QQ ", "input method", "", "most beautiful application", "AndevUI", "mogujie.com"}; @ 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 <10; I ++) {Tag tag = new Tag (); tag. setId (I); tag. setChecked (true); tag. setTitle (titles [I]); mTags. add (tag );}}}
