修改部分字体

• 系统自带字体
    系统自带的字体有四种类型normal、serif、sans和monospace，直接在布局文件中设置即可：

android:typeface="xxx"

• 通过Typeface.createFromAsset加载指定ttf字体，如：

Typeface typeface = Typeface.createFromAsset(getAssets(), "heijian.ttf");

全局修改字体

  全局修改的文字类型只有TextView和EditText两种，即除了EditText控件及其相关控件之外的所有类型的字体都为TextView类型

// BaseActivity
import android.content.Context;
import android.graphics.Typeface;
import android.os.Bundle;
import android.support.v4.view.LayoutInflaterCompat;
import android.support.v4.view.LayoutInflaterFactory;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.app.AppCompatDelegate;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;

public class BaseActivity extends AppCompatActivity {

    public static Typeface typeface1;
    public static Typeface typeface2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        if (typeface1 == null) {
            typeface1 = Typeface.createFromAsset(getAssets(), "yrdzst.ttf");
        }

        if(typeface2 == null){
            typeface2 = Typeface.createFromAsset(getAssets(), "heijian.ttf");
        }

        LayoutInflaterCompat.setFactory(LayoutInflater.from(this), new LayoutInflaterFactory() {
            @Override
            public View onCreateView(View parent, String name, Context context, AttributeSet attrs) {
                AppCompatDelegate delegate = getDelegate();
                View view = delegate.createView(parent, name, context, attrs);
                // 如果控件文字类型属于TextView，则加载第一种字体
                if (view != null && (view instanceof TextView)) {
                    ((TextView) view).setTypeface(typeface1);
                }

                // 如果控件文字类型属于EditText，则加载第二种字体
                if(view !=null && (view instanceof EditText)){
                    ((EditText) view).setTypeface(typeface2);
                }

                return view;
            }
        });
        super.onCreate(savedInstanceState);
    }
}

  注1：想要修改字体的Activity直接继承BaseActivity即可，如果想要再细化修改，再到相应的Activity中使用Typeface.createFromAsset方式修改字体
  注2：需要在module的build.gradle中的dependencies节点下加入：

    compile 'com.zhy:base-adapter:3.0.3'
    compile 'com.zhy:base-rvadapter:3.0.3'

  注3：字体文件需在和java文件平级的目录中新建assets文件夹，并将字体文件放入其中，这样加载字体：

Typeface typeface = Typeface.createFromAsset(getAssets(), "heijian.ttf");
