android 用paint，canvas 绘图
（1）主要用了paint ，canvas 两个类中的方法
（2）主要用了画线和画圆的方法。
（3）drawline（起始点轴坐标，起始点y轴坐标，终点轴坐标，终点y轴坐标）
（4）drawcircle（圆心x轴坐标，圆心y轴坐标，半径，画布）
效果图：
直接上代码了：
package com.example.drawpicture; import android.content.Context; import android.graphics.Canvas; import android.graphics.Color; import android.graphics.Paint; import android.view.View; class Customview1 extends View{ Paint paint; public Customview1(Context context) { super(context); paint = new Paint(); paint.setColor(Color.BLACK); paint.setStrokeJoin(Paint.Join.ROUND); paint.setStrokeCap(Paint.Cap.ROUND); paint.setStrokeWidth(3); paint.setTextSize(40);//设置字体大小 } protected void onDraw(Canvas canvas) { //横线 //top canvas.drawLine(30, 30, 450,30, paint); canvas.drawLine( 30, 100, 450,100, paint); canvas.drawLine( 30, 170, 450,170, paint); canvas.drawLine( 30, 240, 450,240, paint); canvas.drawLine( 30, 310, 450,310, paint); // bottom canvas.drawText(" 楚 河 ", 65, 355, paint);//使用画笔paint canvas.drawText(" 汉 界 ", 320,355 , paint);//使用画笔paint canvas.drawLine(30, 380, 450,380, paint); canvas.drawLine( 30, 450, 450,450, paint); canvas.drawLine( 30, 520, 450,520, paint); canvas.drawLine( 30, 590, 450,590, paint); canvas.drawLine( 30, 660, 450,660, paint); //竖线 //left canvas.drawLine(30, 30,30,660, paint); canvas.drawLine(83, 30, 83,310, paint); canvas.drawLine(136, 30, 136,310, paint); canvas.drawLine(189, 30, 189,310, paint); canvas.drawLine(242, 30, 242,310, paint); canvas.drawLine(294, 30, 294,310, paint); canvas.drawLine(347, 30, 347,310, paint); canvas.drawLine(398, 30, 398,310, paint); //right canvas.drawLine(83, 380, 83,660, paint); canvas.drawLine(136, 380, 136,660, paint); canvas.drawLine(189, 380, 189,660, paint); canvas.drawLine(242, 380, 242,660, paint); canvas.drawLine(294, 380, 294,660, paint); canvas.drawLine(347, 380, 347,660, paint); canvas.drawLine(398, 380, 398,660, paint); canvas.drawLine(450,30 ,450,660, paint); //大营 canvas.drawLine(189, 30, 294,170, paint); canvas.drawLine(294, 30, 189,170, paint); canvas.drawLine(189,520, 294,660, paint); canvas.drawLine(294,520, 189,660, paint); //topcircle canvas.drawCircle(450, 240,20, paint); canvas.drawCircle(346, 240,20, paint); canvas.drawCircle(242, 240,20, paint); canvas.drawCircle(396, 170,20, paint); canvas.drawCircle(450, 30,20, paint); canvas.drawCircle(396, 30,20, paint); canvas.drawCircle(346, 30,20, paint); canvas.drawCircle(294, 30,20, paint); canvas.drawCircle(242, 30,20, paint); canvas.drawCircle(189, 30,20, paint); canvas.drawCircle(135, 30,20, paint); canvas.drawCircle(83, 30,20, paint); canvas.drawCircle(30, 30,20 , paint); canvas.drawCircle(83, 170,20, paint); canvas.drawCircle(135, 240,20, paint); canvas.drawCircle(30, 240,20, paint); //bottomcircle canvas.drawCircle(450, 450,20, paint); canvas.drawCircle(346, 450,20, paint); canvas.drawCircle(242, 450,20, paint); canvas.drawCircle(396, 520,20, paint); canvas.drawCircle(450, 660,20, paint); canvas.drawCircle(396, 660,20, paint); canvas.drawCircle(346, 660,20, paint); canvas.drawCircle(294, 660,20, paint); canvas.drawCircle(242, 660,20, paint); canvas.drawCircle(189, 660,20, paint); canvas.drawCircle(135, 660,20, paint); canvas.drawCircle(83, 660,20, paint); canvas.drawCircle(30, 660,20, paint); canvas.drawCircle(83, 520,20, paint); canvas.drawCircle(135, 450,20, paint); canvas.drawCircle(30, 450,20, paint); paint.setColor(Color.RED); paint.setTextSize(20); canvas.drawText("兵", 21,458, paint); canvas.drawText("兵", 127,458, paint); canvas.drawText("兵", 232,458 , paint); canvas.drawText("炮", 388,527, paint); canvas.drawText("车", 440,668 , paint); canvas.drawText("馬", 388,668 , paint); canvas.drawText("象", 335,668 , paint); canvas.drawText("仕", 285,668 , paint); canvas.drawText("帥", 232,668 , paint); canvas.drawText("仕", 180,668 , paint); canvas.drawText("象", 127,668 , paint); canvas.drawText("馬", 72,668 , paint); canvas.drawText("车", 21,668 , paint); canvas.drawText("炮", 72, 527, paint); canvas.drawText("兵", 335,458 , paint); canvas.drawText("兵", 440,458, paint); canvas.drawText("卒", 21,245, paint); canvas.drawText("卒", 127,245, paint); canvas.drawText("卒", 232,245 , paint); canvas.drawText("炮", 72, 177, paint); canvas.drawText("车", 21,35 , paint); canvas.drawText("馬", 72,35 , paint); canvas.drawText("象", 127,35 , paint); canvas.drawText("士", 180,35 , paint); canvas.drawText("将", 232,35 , paint); canvas.drawText("士", 285,35 , paint); canvas.drawText("象", 335,35 , paint); canvas.drawText("馬", 388,35 , paint); canvas.drawText("车", 440,35 , paint); canvas.drawText("炮", 388, 177, paint); canvas.drawText("卒", 335,247 , paint); canvas.drawText("卒", 440,247, paint); } }
