利用Typeface显示.ttf文件中的字符在TextView上面。

效果图：

TypefaceTextView

代码如下：

  /**   * 作者：僧格洛卓    * 描述：TypefaceTextView   */  public class TypefaceTextView extends TextView {      public TypefaceTextView(Context context) {          super(context);          init(context, null);      }      public TypefaceTextView(Context context, @Nullable AttributeSet attrs) {          super(context, attrs);          init(context, attrs);      }      private void init(Context context, AttributeSet attrs) {          // 自定义属性          TypedArray mArray = context.obtainStyledAttributes(attrs, R.styleable.TypefaceTextView);          String mTypefacePath = mArray.getString(R.styleable.TypefaceTextView_typefacePath);          String mTypefaceUnicode = mArray.getString(R.styleable.TypefaceTextView_typefaceUnicode);          mArray.recycle();          if (!TextUtils.isEmpty(mTypefacePath) && !TextUtils.isEmpty(mTypefaceUnicode)) {              setTypeface(Typeface.createFromAsset(context.getAssets(), mTypefacePath));              setText(mTypefaceUnicode);          }      }  }

自定义属性：

    <declare-styleable name="TypefaceTextView">        <!--assets文件夹下的.ttf文件地址-->        <attr name="typefacePath" format="string" />        <!--Unicode码-->        <attr name="typefaceUnicode" format="reference|string" />    </declare-styleable>

在布局中使用：

  <?xml version="1.0" encoding="utf-8"?>  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:typefacetext="http://schemas.android.com/apk/res-auto"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:background="@color/white"     android:gravity="center"     android:orientation="horizontal">    <com.example.app.view.widget.TypefaceTextView        android:id="@+id/navigation_home"        android:layout_width="0dp"        android:layout_height="match_parent"        android:layout_weight="1"        android:gravity="center"        android:padding="5dp"        android:textColor="@color/gray"        android:textSize="25dp"        typefacetext:typefacePath="navigation/home_page_navigation.ttf"        typefacetext:typefaceUnicode="@string/icon_home" />    <com.example.app.view.widget.TypefaceTextView        android:id="@+id/navigation_search"        android:layout_width="0dp"        android:layout_height="match_parent"        android:layout_weight="1"        android:gravity="center"        android:padding="5dp"        android:textColor="@color/gray"        android:textSize="25dp"        typefacetext:typefacePath="navigation/home_page_navigation.ttf"        typefacetext:typefaceUnicode="@string/icon_search" />    <com.example.app.view.widget.TypefaceTextView        android:id="@+id/navigation_message"        android:layout_width="0dp"        android:layout_height="match_parent"        android:layout_weight="1"        android:gravity="center"        android:padding="5dp"        android:textColor="@color/gray"        android:textSize="25dp"        typefacetext:typefacePath="navigation/home_page_navigation.ttf"        typefacetext:typefaceUnicode="@string/icon_message" />    <com.example.app.view.widget.TypefaceTextView        android:id="@+id/navigation_user"        android:layout_width="0dp"        android:layout_height="match_parent"        android:layout_weight="1"        android:gravity="center"        android:textColor="@color/gray"        android:textSize="20dp"        typefacetext:typefacePath="navigation/home_page_navigation.ttf"        typefacetext:typefaceUnicode="@string/icon_user" /></LinearLayout>

属性说明：

typefacetext:typefacePath="navigation/home_page_navigation.ttf"

navigation/home_page_navigation.ttf 为assets文件夹下.ttf文件

typefacetext:typefaceUnicode="@string/icon_home"

@string/icon_home 为string中的Unicode字符码

案例中Unicode对应的string

  <resources>    <string name="icon_home">>&#xe6a9;</string>    <string name="icon_search">>&#xe674;</string>    <string name="icon_message">&#xe64b;</string>    <string name="icon_user">&#xe662;</string>  </resources>
