大家好,又见面了,我是全栈君,祝每个程序员都可以多学几门语言。
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; } }
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); } } }
这个TagView就是标签视图,标签信息由他来显示。对应的xml文件例如以下,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" />
