(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;

      paint.setStrokeCap(Paint.Cap.ROUND);    
      paint.setStrokeWidth(3);    
      paint.setTextSize(40);//设置字体大小    
          }
