字体工具类

import android.app.Application;
import android.graphics.Typeface;

/**

public class CustomFontManager {
    private static CustomFontManager singleton;
    private Typeface lightFont;
    private Typeface boldFont;

    private CustomFontManager() {

    }

        if (singleton == null) {

自定义字体基类

import android.content.Context;
import android.support.v7.widget.AppCompatTextView;
import android.util.AttributeSet;

/**
 * 自定义字体类型 基类
 * author：wiki on 2018/11/9
 * email：zhengweiqunemail@qq.com
 */
public abstract class BaseCustomTextView extends AppCompatTextView {

    public BaseCustomTextView(Context context) {
        super(context);
        setFont();
    }

    public BaseCustomTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        setFont();
    }

    public BaseCustomTextView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        setFont();
    }

    protected abstract void setFont();
}

字体类

import android.content.Context;
import android.util.AttributeSet;

import com.sugrsugr.ivyapp.sugrsmartivy.util.CustomFontManager;

/**
 * SFCompactText-Semibold 字体
 * author：wiki on 2018/11/9
 * email：zhengweiqunemail@qq.com
 */
public class CustomBoldTextView extends BaseCustomTextView {

    public CustomBoldTextView(Context context) {
        super(context);
    }

    public CustomBoldTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomBoldTextView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    protected void setFont() {
        setTypeface(CustomFontManager.getInstance().getBoldFont());
    }
}

AppManager中初始化字体

import android.content.Context;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.support.multidex.MultiDexApplication;

import com.sugrsugr.ivyapp.sugrsmartivy.util.CustomFontManager;

/**
 * 初始化资源
 * author：wiki on 2018/11/9
 * email：zhengweiqunemail@qq.com
 */
public final class AppManager extends MultiDexApplication {

    private static AppManager instance;
    
    public static AppManager getInstance() {
        return instance;
    }

    public static Context getContext() {
        return instance.getApplicationContext();
    }


    @Override
    public void onCreate() {
        super.onCreate();
        instance = this;
        //初始化字体类
        CustomFontManager.getInstance().init(this);
    }

    /**
     * 获取本地软件版本号
     */
    public static int getLocalVersion(Context ctx) {
        int localVersion = 0;
        try {
            PackageInfo packageInfo = ctx.getApplicationContext()
                    .getPackageManager()
                    .getPackageInfo(ctx.getPackageName(), 0);
            localVersion = packageInfo.versionCode;
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }
        return localVersion;
    }

    /**
     * 获取本地软件版本号名称
     */
    public static String getLocalVersionName(Context ctx) {
        String localVersion = "";
        try {
            PackageInfo packageInfo = ctx.getApplicationContext()
                    .getPackageManager()
                    .getPackageInfo(ctx.getPackageName(), 0);
            localVersion = packageInfo.versionName;
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }
        return localVersion;
    }

}

布局文件中使用

<com.sugrsugr.ivyapp.sugrsmartivy.widget.CustomBoldTextView
            android:layout_marginTop="27dp"
            android:layout_marginBottom="16dp"
            android:textColor="@color/green_8CC63F"
            android:textSize="25sp"
            tools:text="Hi" />
