android-iconify 使用详解 有图有真相

iconify是一个矢量图标库,包含使用 Dave Gandy 制作的超过370中矢量字体图标,可以使Android应用开发者免于制作多种适用于不同屏幕大小尺寸的图片,从而提高开发者工作效率。
适用场景:
1、iconify原作者提供了三种他自定义的控件:IconTextView、IconButton、IconToggleButton,可以直接使用这三类控件来显示iconify中提供的字体图标;
2、在java代码中通过使用一个IconDrawable为具有setIcon(Drawable drawable)方法的控件设置该字体图标
优点:由于这些图标均是矢量字体图标,所以不仅可以无限放大而不会失真,模糊,而且可以将适用于text的属性应用于这些矢量图标上,从而实现改变图标颜色、添加阴影等效果
缺点:目前在xml文件中使用图标库中的资源时,需要自己对照查阅不同图标所对应的标记,自己手敲标记,这样不仅麻烦,而且容易出错。
在需要使用iconify的app的build.gradle的dependencies中添加依赖(下面添加了整个库,在实际开发过程中,可以只添加自己需要的某一个或几个库即可):
dependencies { compile 'com.joanzapata.iconify:android-iconify-fontawesome:2.2.2' // (v4.5) compile 'com.joanzapata.iconify:android-iconify-entypo:2.2.2' // (v3,2015) compile 'com.joanzapata.iconify:android-iconify-typicons:2.2.2' // (v2.0.7) compile 'com.joanzapata.iconify:android-iconify-material:2.2.2' // (v2.0.0) compile 'com.joanzapata.iconify:android-iconify-material-community:2.2.2' // (v1.4.57) compile 'com.joanzapata.iconify:android-iconify-meteocons:2.2.2' // (latest) compile 'com.joanzapata.iconify:android-iconify-weathericons:2.2.2' // (v2.0) compile 'com.joanzapata.iconify:android-iconify-simplelineicons:2.2.2' // (v1.0.0) compile 'com.joanzapata.iconify:android-iconify-ionicons:2.2.2' // (v2.0.1) }
自定义一个继承自Application类的类:
public class MyApplication extends Application { @Override public void onCreate() { super.onCreate(); Iconify .with(new FontAwesomeModule()) .with(new EntypoModule()) .with(new TypiconsModule()) .with(new MaterialModule()) .with(new MaterialCommunityModule()) .with(new MeteoconsModule()) .with(new WeathericonsModule()) .with(new SimpleLineIconsModule()) .with(new IoniconsModule()); } }
<application android:name="com.application.MyApplication" android:icon="@mipmap/ic_launcher" android:label="@string/app_name">
其中fa xxx 是Font Awesome的图标库。icon-scan icon-wx-pay 是自定义阿里图标库

将上文截图中的 iconfont.ttf 复制到assets目录
自定义FontModule可以参考FontAwesomeModule,需要实现IconFontDescriptor 接口以及实现Icon接口来添加我们具体的图标
public class IconFontModule implements IconFontDescriptor { @Override public String ttfFileName() { return "iconfont.ttf";//上文复制的字体文件 } @Override public Icon[] characters() { return IconFonts.values(); } }
public enum IconFonts implements Icon { // 将/&#x替换成\u icon_scan('\ue609'), icon_ali_pay('\ue65e'), icon_wx_pay('\ue615'), icon_qq_pay('\ue60d'); private char character; IconFonts(char character) { this.character = character; } @Override public String key() { return name().replace('_', '-'); } @Override public char character() { return character; } }
IconDrawable iconDrawable = new IconDrawable(this, FontAwesomeIcons.fa_key) .colorRes(R.color.colorAccent) .actionBarSize(); imageView.setImageDrawable(iconDrawable);
