Drawing operations want Paint. In this Paintyou set Paint.setFlags(Paint.ANTI_ALIAS_FLAG)
绘图操作要Paint。在这个Paint你设置Paint.setFlags(Paint.ANTI_ALIAS_FLAG)

Check this out. It fairly uses smooth edges.. http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/FingerPaint.html
看一下这个。它相当使用平滑边缘.. http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/FingerPaint.html
The paint properties needed to get anti-aliasing is :
获得抗锯齿所需的绘制属性是：
mPaint = new Paint();
mPaint.setAntiAlias(true);
For drawing use:
用于绘图：
mPath = new Path();
mPath.reset();
mPath.moveTo(x, y);//can be used where to trigger the path
onDraw method should contain:
onDraw 方法应包含：
canvas.drawPath(mPath, mPaint);
Declare the mPath and mPaint as global.
将 mPath 和 mPaint 声明为全局。
