Paint API之Typeface(字型)

1.字体的可选风格

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:sansserifmonospace 而提供的可选静态对象值有五个:

  • DEFAULT:默认正常字体对象
  • DEFAULT_BOLD:默认的字体对象,注意:这实际上不可能是粗体的,这取决于字体设置。 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");


4.使用代码示例:

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~

本节小结:

好的,一连十几节的Paint API详解就到这里了,应该已经涵盖大部分的可能会用到的API了, 不知道你都Get了没,这些都是为我们进阶部分的自定义控件做铺垫~嗯,就说这么多,谢谢~
