本文实例为大家分享了Android实现球赛比分条效果的具体代码，供大家参考，具体内容如下

效果图如下所示：

该控件需要输入两个参数，左边的得分数和右边的的分数

然后根据两边的得分的比例绘制中间的比分条

首先将控件的宽度平均分配为10分，第一份和最后一份分别绘制左边的比分数字和右边的比分数字

中间的8分宽度绘制比分条

根据左右两个比分所占的比例，绘制两个两条首位相连的线段即可

完整代码如下：

public class CustomScoreBar extends View {

private Context context;

private TypedValue typedValue;

private static final int DEGREE =10;

private int mColorLeft, mColorRight;

private int mScoreLeft, mScoreRight;

//各种画笔

private Paint paintBar =new Paint();

private Paint paintText=new Paint();

public CustomScoreBar(Context context) {

super(context);

this.context=context;

init();

}

public CustomScoreBar(Context context, AttributeSet attrs) {

super(context, attrs);

this.context=context;

init();

}

public CustomScoreBar(Context context, AttributeSet attrs, int defStyleAttr) {

super(context, attrs, defStyleAttr);

this.context=context;

init();

}

private void init() {

//初始化数据，默认属性

mColorLeft = Color.rgb(95, 112, 72);

mColorRight = Color.rgb(69, 91, 136);

mScoreLeft =5;

mScoreRight =8;

typedValue=new TypedValue();

context.getTheme().resolveAttribute(R.attr.maintextclor,typedValue,true);

}

@Override

protected void onDraw(Canvas canvas) {

super.onDraw(canvas);

float width=getWidth();

float height=getHeight();

//文字画笔设置

paintText.reset();

paintText.setAntiAlias(true);

//文字的大小取控件宽度的十分之一和高度的二分之一的最小值

paintText.setTextSize(Math.min(width / DEGREE, height) / 2);

paintText.setColor(getResources().getColor(typedValue.resourceId));

/*Paint.Align.CENTER：The text is drawn centered horizontally on the x,y origin*/

paintText.setTextAlign(Paint.Align.CENTER);

//绘制中间的横线的画笔

paintBar.reset();

paintBar.setAntiAlias(true);

paintBar.setStyle(Paint.Style.STROKE);

//画笔的高度为控件高度的十分之一

paintBar.setStrokeWidth(height/10);

//测量字体

Paint.FontMetrics fontMetrics = paintText.getFontMetrics();

float textBaseLineOffset = (fontMetrics.bottom - fontMetrics.top) / 2 - fontMetrics.bottom;

//绘制左边的比分文字

//把控件宽度分为10份，第一份和第十份分别绘制左边和右边的文字

//中间的8份宽度绘制比分条

canvas.drawText("" + mScoreLeft, width / DEGREE / 2, height / 2 + textBaseLineOffset, paintText);

paintBar.setColor(mColorLeft);

// drawLine(float startX, float startY, float stopX, float stopY,Paint paint)*/

//按照比例绘制左边比分对应长度的比分条

canvas.drawLine(width / DEGREE, height / 2, width / DEGREE + width * (DEGREE - 2) / DEGREE * mScoreLeft / (mScoreLeft + mScoreRight), height / 2, paintBar);

//测量右边的比分文字

fontMetrics = paintText.getFontMetrics();

textBaseLineOffset = (fontMetrics.bottom - fontMetrics.top) / 2 - fontMetrics.bottom;

//在控件宽度的最后十分之一绘制右边的比分数字

canvas.drawText("" + mScoreRight, width-width / DEGREE / 2, height / 2 + textBaseLineOffset,paintText);

paintBar.setColor(mColorRight);

//绘制右边的比分对应长度的比分条

canvas.drawLine(width/ DEGREE +width*(DEGREE -2)/ DEGREE * mScoreLeft /(mScoreLeft + mScoreRight),height/2,width*(DEGREE -1)/ DEGREE,height/2, paintBar);

}

public void setScores(int score1, int score2) {

this.mScoreLeft =score1;

this.mScoreRight =score2;

invalidate();

}

}
