自定义TextView显示.ttf文件中的字符

利用Typeface显示.ttf文件中的字符在TextView上面。

效果图：

代码如下：

/** * 作者：秦川小将 * 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>
