android canvas详解
Android中使用图形处理引擎，2D部分是android SDK内部自己提供，3D部分是用Open GL ES 1.0。今天我们主要要了解的是2D相关的，如果你想看3D的话那么可以跳过这篇文章。大部分2D使用的api都在android.graphics和android.graphics.drawable包中。他们提供了图形处理相关的： Canvas、ColorFilter、Point(点)和RetcF(矩形)等，还有一些动画相关的：AnimationDrawable、 BitmapDrawable和TransitionDrawable等。以图形处理来说，我们最常用到的就是在一个View上画一些图片、形状或者自定义的文本内容，这里我们都是使用Canvas来实现的。你可以获取View中的Canvas对象，绘制一些自定义形状，然后调用View. invalidate方法让View重新刷新，然后绘制一个新的形状，这样达到2D动画效果。下面我们就主要来了解下Canvas的使用方法。 Canvas对象的获取方式有两种：一种我们通过重写View.onDraw方法，View中的Canvas对象会被当做参数传递过来，我们操作这个Canvas，效果会直接反应在View中。另一种就是当你想创建一个Canvas对象时使用的方法： 1 2 Bitmap b = Bitmap.createBitmap(100, 100, Bitmap.Config.ARGB_8888); Canvas c =newCanvas(b); 上面代码创建了一个尺寸是100*100的Bitmap，使用它作为Canvas操作的对象，这时候的Canvas就是使用创建的方式。当你使用创建的Canvas在bitmap上执行绘制方法后，你还可以将绘制的结果提交给另外一个Canvas，这样就可以达到两个Canvas协作完成的效果，简化逻辑。但是android SDK建议使用View.onDraw参数里提供的Canvas就好，没必要自己创建一个新的Canvas对象。接下来我们看看Canvas提供我们哪些绘制图形的方法。我们创建一个自定义View对象，使用onDraw方法提供的Canvas进行绘制图形。 CanvasDemoActivity.java： 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 package com.android777.demo.uicontroller.graphics; import android.app.Activity; import android.content.Context; import android.graphics.Canvas; import android.graphics.Color; import android.graphics.Paint; import android.os.Bundle; import android.view.View; public class CanvasDemoActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(newCustomView1(this)); } /** * 使用内部类自定义一个简单的View * @author Administrator * */ class CustomView1 extends View{ Paint paint; public CustomView1(Context context) { super(context); paint =newPaint();//设置一个笔刷大小是3的黄色的画笔 paint.setColor(Color.YELLOW); paint.setStrokeJoin(Paint.Join.ROUND); paint.setStrokeCap(Paint.Cap.ROUND); paint.setStrokeWidth(3); } //在这里我们将测试canvas提供的绘制图形方法 @Override protected void onDraw(Canvas canvas) { } } } 执行结果是一片黑色的区域，因为在自定义的CustomView1中，我们没有做任何的绘制操作。canvas提供的绘制图形的方法都是以draw开头的，我们可以查看api：从上面方法的名字看来我们可以知道Canvas可以绘制的对象有：弧线(arcs)、填充颜色(argb和color)、 Bitmap、圆(circle和oval)、点(point)、线(line)、矩形(Rect)、图片(Picture)、圆角矩形 (RoundRect)、文本(text)、顶点(Vertices)、路径(path)。通过组合这些对象我们可以画出一些简单有趣的界面出来，但是光有这些功能还是不够的，如果我要画一个仪表盘(数字围绕显示在一个圆圈中)呢？幸好Android还提供了一些对Canvas位置转换的方法：rorate、scale、translate、skew(扭曲)等，而且它允许你通过获得它的转换矩阵对象(getMatrix方法，不知道什么是转换矩阵？看这里) 直接操作它。这些操作就像是虽然你的笔还是原来的地方画，但是画纸旋转或者移动了，所以你画的东西的方位就产生变化。为了方便一些转换操作，Canvas 还提供了保存和回滚属性的方法(save和restore)，比如你可以先保存目前画纸的位置(save)，然后旋转90度，向下移动100像素后画一些图形，画完后调用restore方法返回到刚才保存的位置。下面我们就演示下canvas的一些简单用法： 1 2 3 4 protected void onDraw(Canvas canvas) { canvas.drawCircle(100, 100, 90, paint); } 效果是： 1 2 3 4 5 6 7 8 9 10 11 12 13 14 @Override protected void onDraw(Canvas canvas) { //绘制弧线区域 RectF rect =newRectF(0, 0, 100, 100); canvas.drawArc(rect,//弧线所使用的矩形区域大小 0, //开始角度 90,//扫过的角度 false,//是否使用中心 paint); } 使用下面的代码： 1 2 3 4 5 6 7 8 9 10 11 12 13 protected void onDraw(Canvas canvas) { //绘制弧线区域 RectF rect =newRectF(0, 0, 100, 100); canvas.drawArc(rect,//弧线所使用的矩形区域大小 0, //开始角度 90,//扫过的角度 true,//是否使用中心 paint); } 两图对比我们可以发现，当 drawArcs(rect,startAngel,sweepAngel,useCenter,paint)中的useCenter为false时，弧线区域是用弧线开始角度和结束角度直接连接起来的，当useCenter为true时，是弧线开始角度和结束角度都与中心点连接，形成一个扇形。 1 2 3 4 5 protected void onDraw(Canvas canvas) { canvas.drawColor(Color.BLUE); } canvas.drawColor是直接将View显示区域用某个颜色填充满。 1 2 3 4 5 6 7 @Override protected void onDraw(Canvas canvas) { //画一条线 canvas.drawLine(10, 10, 100, 100, paint); } Canvas.drawOval： 1 2 3 4 5 6 7 8 9 @Override protected void onDraw(Canvas canvas) { //定义一个矩形区域 RectF oval =newRectF(0,0,200,300); //矩形区域内切椭圆 canvas.drawOval(oval, paint); } canvas.drawPosText： 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 @Override protected void onDraw(Canvas canvas) { //按照既定点绘制文本内容 canvas.drawPosText("Android777",newfloat[]{ 10,10,//第一个字母在坐标10,10 20,20,//第二个字母在坐标20,20 30,30,//.... 40,40, 50,50, 60,60, 70,70, 80,80, 90,90, 100,100 }, paint); } canvas.drawRect： 1 2 3 4 5 6 7 8 9 10 @Override protected void onDraw(Canvas canvas) { RectF rect =newRectF(50, 50, 200, 200); canvas.drawRect(rect, paint); } } canvas.drawRoundRect： 1 2 3 4 5 6 7 8 9 10 11 @Override protected void onDraw(Canvas canvas) { RectF rect =newRectF(50, 50, 200, 200); canvas.drawRoundRect(rect, 30,//x轴的半径 30,//y轴的半径 paint); } canvas.drawPath： 1 2 3 4 5 6 7 8 9 10 11 12 @Override protected void onDraw(Canvas canvas) { Path path =newPath();//定义一条路径 path.moveTo(10, 10);//移动到坐标10,10 path.lineTo(50, 60); path.lineTo(200,80); path.lineTo(10, 10); canvas.drawPath(path, paint); } canvas.drawTextOnPath： 1 2 3 4 5 6 7 8 9 10 11 12 13 @Override protected void onDraw(Canvas canvas) { Path path =newPath();//定义一条路径 path.moveTo(10, 10);//移动到坐标10,10 path.lineTo(50, 60);
