Android中使用FontAwesome

原理

FontAwesome 图标集背后的思想非常简单，图标被视为字符（character）。你选择列表中的一个图标，记下它的Unicode的字符，在TextView中使用它告诉安卓使用FontAwesome字体来渲染。

你可以在下面的链接中找到所需要的图标。

添加依赖

在build.gradle添加依赖，这样Android Studio自动帮你下载依赖包。

dependencies {    compile fileTree(include: ['*.jar'], dir: 'libs')    testCompile 'junit:junit:4.12'    compile 'com.android.support:appcompat-v7:23.0.0'    compile 'com.android.support:design:23.0.0'    //android-iconify    compile 'com.joanzapata.iconify:android-iconify-fontawesome:2.1.1' // (v4.5)    compile 'com.joanzapata.iconify:android-iconify-entypo:2.1.1' // (v3,2015)    compile 'com.joanzapata.iconify:android-iconify-typicons:2.1.1' // (v2.0.7)    compile 'com.joanzapata.iconify:android-iconify-material:2.1.1' // (v2.0.0)    compile 'com.joanzapata.iconify:android-iconify-material-community:2.1.1' // (v1.2.65)    compile 'com.joanzapata.iconify:android-iconify-meteocons:2.1.1' // (latest)    compile 'com.joanzapata.iconify:android-iconify-weathericons:2.1.1' // (v2.0)    compile 'com.joanzapata.iconify:android-iconify-simplelineicons:2.1.1' // (v1.0.0)    compile 'com.joanzapata.iconify:android-iconify-ionicons:2.1.1' // (v2.0.1)    }

加载使用

在Android view中要使用图标，需要在activity的中onCreate()中加载：
