Android--paint应用举例

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();
      paint.setTextSize();//设置字体大小
          }
