——8.3.15 Paint API之——Typeface(字型)
标签(空格分隔):
本节引言:本节带来Paint API系列的最后一个API,Typeface(字型),由字义,我们大概可以猜到,这个
API是用来设置字体以及字体风格的,使用起来也非常的简单!下面我们来学习下Typeface的一些相关
的用法!
四个整型常量:
BOLD:加粗 ITALIC:斜体 BOLD_ITALIC:粗斜体 NORMAL:正常 2.可选字体对象(Typeface)Android系统默认支持三种字体,分别为:sans,serif,monospace
而提供的可选静态对象值有五个:
由getStyle()来确定 MONOSPACE:monospace 字体风格 SANS_SERIF:sans serif字体风格 SERIF:serif字体风格 3.自定义创建字型
可能默认的三种字体并不能满足你,可能你喜欢MAC的字体——Monaco字体,你想让你APP
里的文字可以用这种字体,首先准备好我们的TTF文件,然后丢到assets/font/目录下
然后创建对应对象,关键代码如下:
Typeface typeFace =Typeface.createFromAsset(getAssets(),”font/MONACO.ttf”);
运行效果图:
自定义的View类:MyView.java:
/** * Created by Jay on 2015/11/5 0005. */ public class MyView extends View{ private Paint mPaint1,mPaint2,mPaint3,mPaint4,mPaint5; private Context mContext; public MyView(Context context) { this(context,null); } public MyView(Context context, AttributeSet attrs) { super(context, attrs); mContext = context; init(); } public MyView(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } private void init(){ mPaint1 = new Paint(); mPaint2 = new Paint(); mPaint3 = new Paint(); mPaint4 = new Paint(); mPaint5 = new Paint(); mPaint1.setColor(Color.RED); mPaint2.setColor(Color.BLUE); mPaint3.setColor(Color.BLACK); mPaint4.setColor(Color.YELLOW); mPaint5.setColor(Color.GRAY); mPaint1.setTextSize(100); mPaint2.setTextSize(100); mPaint3.setTextSize(100); mPaint4.setTextSize(100); mPaint5.setTextSize(100); mPaint1.setTypeface(Typeface.DEFAULT_BOLD); mPaint2.setTypeface(Typeface.MONOSPACE); mPaint3.setTypeface(Typeface.SANS_SERIF); mPaint4.setTypeface(Typeface.SERIF); mPaint5.setTypeface(Typeface.createFromAsset(mContext.getAssets(), font/MONACO.ttf)); } @Override protected void onDraw(Canvas canvas) { canvas.drawText(Coder-pig, 100, 100, mPaint1); canvas.drawText(Coder-pig, 100, 200, mPaint2); canvas.drawText(Coder-pig, 100, 300, mPaint3); canvas.drawText(Coder-pig, 100, 400, mPaint4); canvas.drawText(Coder-pig, 100, 500, mPaint5); } }恩呢,非常简单~就不解释了,要字体的可以自己百度或者下载示例代码~
