Android(安卓)优惠卷样式

先上图

样式主要是MyCardView

新建MyCardView降代码复制进去

import android.content.Context;import android.graphics.Canvas;import android.graphics.Color;import android.graphics.Paint;import android.util.AttributeSet;import android.widget.LinearLayout;/** * @fileName MyCardView * @date on 2019-01-03 16:16 * @developers czh * @email 1632365610@qq.com */public class MyCardView  extends LinearLayout {    //圆的半径    private int radius = 8;    //圆之间的间距    private int gap = 8;    private Paint mPaint;    public MyCardView(Context context) {        super(context);        init();    }    public MyCardView(Context context, AttributeSet attrs) {        super(context, attrs);        init();    }    public MyCardView(Context context, AttributeSet attrs, int defStyleAttr) {        super(context, attrs, defStyleAttr);        init();    }    private void init() {        mPaint = new Paint();        mPaint.setColor(Color.WHITE);        mPaint.setStyle(Paint.Style.FILL);        mPaint.setDither(true);    }    @Override    protected void onDraw(Canvas canvas) {        super.onDraw(canvas);        //圆的个数        int roundNum = getWidth() / (radius * 2 + gap * 2);        for (int i = 1; i <= roundNum; i++) {            canvas.drawCircle((gap + radius) * (2 * i - 1), 0, radius, mPaint);            canvas.drawCircle((gap + radius) * (2 * i - 1), getHeight(), radius, mPaint);        }    }}布局源码
