I. Adding Dependency

compile "com.mikepenz:iconics-core:2.8.2@aar"

compile 'com.android.support:appcompat-v7:25.1.0'

2. Choosing the Icon Library to Depend on

compile 'com.mikepenz:google-material-typeface:3.0.1.0.original@aar'
compile 'com.mikepenz:material-design-iconic-typeface:2.2.0.2@aar'
compile 'com.mikepenz:fontawesome-typeface:4.7.0.0@aar'
compile 'com.mikepenz:octicons-typeface:3.2.0.2@aar'
compile 'com.mikepenz:meteocons-typeface:1.1.0.2@aar'
compile 'com.mikepenz:community-material-typeface:1.8.36.1@aar'
compile 'com.mikepenz:weather-icons-typeface:2.0.10.2@aar'
compile 'com.mikepenz:typeicons-typeface:2.0.7.2@aar'
compile 'com.mikepenz:entypo-typeface:1.0.0.2@aar'

Each icon library has its own website. You can choose your favorite Icon and find the corresponding icon id on it.
Font Awesome
ionicons

Font Awesome as an example

4. Use Drawable (Replace Pictures in Code Dynamically)

new IconicsDrawable(this)
.icon(FontAwesome.Icon.faw_android) //icon Id
.color(Color.RED)
.sizeDp(24) //icon size dp value

private void initView() {
        final CheckBox cb_icon = (CheckBox) findViewById(R.id.cb_icon);
        int themeColor = getResources().getColor(R.color.colorAccent);
        int blackColor = getResources().getColor(R.color.black);
        int sizeDp = 20;
        final Drawable drawable = new IconicsDrawable(this)
                .icon(FontAwesome.Icon.faw_ticket).color(themeColor).sizeDp(sizeDp);
        final Drawable drawableDis = new IconicsDrawable(this).icon(FontAwesome.Icon.faw_angle_right).color(blackColor).sizeDp(sizeDp * 2);
        cb_icon.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (isChecked)
                    cb_icon.setCompoundDrawables(null, drawable, null, null);
                else {
                    cb_icon.setCompoundDrawables(null, drawableDis, null, null);
                }
            }
        });
        cb_icon.setChecked(true);
    }

5. Use directly in XML files

1. Controls customized with open source libraries

   <com.mikepenz.iconics.view.IconicsImageView
            android:id="@+id/iconicsImageView"
            android:layout_width="72dp"
            android:layout_height="72dp"
            android:layout_gravity="center"
            app:iiv_icon="@string/gmd_ac_unit"
            app:iiv_color="@color/colorPrimary"
            app:iiv_size="36dp"
            />
        <com.mikepenz.iconics.view.IconicsTextView
            android:text="abc{ion-ios-cloud-upload}defgh{faw-adjust}ijk{ion-ios-cloud-upload}"
            android:textColor="@android:color/holo_red_dark"
            android:layout_width="wrap_content"
            android:layout_height="56dp"
            android:textSize="16sp"/>
        <com.mikepenz.iconics.view.IconicsButton
            android:text="{faw-adjust} Button"
            android:layout_width="120dp"
            android:layout_height="60dp"/>

   
   

2. Use common controls (registration required)
   There are two ways

   1. Add code to onCreate function

      @Override
      protected void onCreate(Bundle savedInstanceState) {
      LayoutInflaterCompat.setFactory(getLayoutInflater(), new IconicsLayoutInflater(getDelegate()));
      super.onCreate(savedInstanceState);
      }

   2. Rewrite attchBaseContext function

      @Override
      protected void attachBaseContext(Context newBase) {
      super.attachBaseContext(IconicsContextWrapper.wrap(newBase));
      }

Then you can use it.

<ImageView
            android:layout_width="25dp"
            android:layout_height="25dp"
            app:ico_color="@color/black"
            app:ico_icon="ion_ios_eye"
            android:layout_marginRight="15dp"
            app:ico_size="30dp"
            />

There is a pit here.

After all the steps have been correctly completed, AS will still report red-line errors.

Look through the issues and say something about it.

xmlns:app="http://schemas.android.com/apk/res-auto"
Change to
xmlns:app="http://schemas.android.com/apk/tool"
However, there is no soft use.

https://github.com/mikepenz/Android-Iconics/issues/174
See this issue, add it directly

Iconics.init(getApplicationContext());
Iconics.registerFont(new GoogleMaterial());

//Note: It should be similar to LayoutInflaterCompat. setFactory (getLayoutInflater (), new Iconics LayoutInflater (getDelegate ());

Then report the mentality of trying, running directly, it can... Sure enough, I am too inexperienced!!!

summary

It's really convenient to use, compared with Ali's Iconfont. Icon is also of good quality.
