2、效果图
没错，这就是我们的进度条效果，横向的模仿了daimajia的进度条样子。不过我们继承子ProgressBar，简单的为其整个容，代码清晰易懂 。为什么说，易懂呢？
横向那个进度条，大家会drawLine()和drawText()吧，那么通过getWidth()拿到控件的宽度，再通过getProgress()拿到进度，按比例控制绘制线的长短，字的位置还不是分分钟的事。
2、实现
横向的滚动条绘制肯定需要一些属性，比如已/未到达进度的颜色、宽度，文本的颜色、大小等。
本来呢，我是想通过系统ProgressBar的progressDrawable，从里面提取一些属性完成绘制需要的参数的。但是，最终呢，反而让代码变得复杂。所以最终还是改用自定义属性。 说道自定义属性，大家应该已经不陌生了。
1、HorizontalProgressBarWithNumber
1、自定义属性
values/attr_progress_bar.xml:
- <?xml version="1.0" encoding="utf-8"?>
- <resources>
- <declare-styleable name="HorizontalProgressBarWithNumber">
- <attr name="progress_unreached_color" format="color" />
- <attr name="progress_reached_color" format="color" />
- <attr name="progress_reached_bar_height" format="dimension" />
- <attr name="progress_unreached_bar_height" format="dimension" />
- <attr name="progress_text_size" format="dimension" />
- <attr name="progress_text_color" format="color" />
- <attr name="progress_text_offset" format="dimension" />
- <attr name="progress_text_visibility" format="enum">
- <enum name="visible" value="0" />
- <enum name="invisible" value="1" />
- </attr>
- </declare-styleable>
- <declare-styleable name="RoundProgressBarWidthNumber">
- <attr name="radius" format="dimension" />
- </declare-styleable>
- </resources>
2、构造中获取

3、onMeasure
刚才不是出onDraw里面写写就行了么，为什么要改onMeasure呢，主要是因为我们所有的属性比如进度条宽度让用户自定义了，所以我们的测量也得稍微变下。
- @Override
- protected synchronized void onMeasure(int widthMeasureSpec,
- int heightMeasureSpec)
- {
- int heightMode = MeasureSpec.getMode(heightMeasureSpec);
- if (heightMode != MeasureSpec.EXACTLY)
- {
- float textHeight = (mPaint.descent() + mPaint.ascent());
- int exceptHeight = (int) (getPaddingTop() + getPaddingBottom() + Math
- .max(Math.max(mReachedProgressBarHeight,
- mUnReachedProgressBarHeight), Math.abs(textHeight)));
- heightMeasureSpec = MeasureSpec.makeMeasureSpec(exceptHeight,
- MeasureSpec.EXACTLY);
- }
- super.onMeasure(widthMeasureSpec, heightMeasureSpec);
- }
测量完，就到我们的onDraw了~~~
4、onDraw
- @Override
- protected synchronized void onDraw(Canvas canvas)
- {
- canvas.save();
- //画笔平移到指定paddingLeft， getHeight() / 2位置，注意以后坐标都为以此为0，0
- canvas.translate(getPaddingLeft(), getHeight() / 2);
- boolean noNeedBg = false;
- //当前进度和总值的比例
- float radio = getProgress() * 1.0f / getMax();
- //已到达的宽度
- float progressPosX = (int) (mRealWidth * radio);
- //绘制的文本
- String text = getProgress() + "%";
- //拿到字体的宽度和高度
- float textWidth = mPaint.measureText(text);
- float textHeight = (mPaint.descent() + mPaint.ascent()) / 2;
- //如果到达最后，则未到达的进度条不需要绘制
- if (progressPosX + textWidth > mRealWidth)
- {
- progressPosX = mRealWidth - textWidth;
- noNeedBg = true;
- }
- // 绘制已到达的进度
- float endX = progressPosX - mTextOffset / 2;
- if (endX > 0)
- {
- mPaint.setColor(mReachedBarColor);
- mPaint.setStrokeWidth(mReachedProgressBarHeight);
- canvas.drawLine(0, 0, endX, 0, mPaint);
- }
- // 绘制文本
- if (mIfDrawText)
- {
- mPaint.setColor(mTextColor);
- canvas.drawText(text, progressPosX, -textHeight, mPaint);
- }
- // 绘制未到达的进度条
- if (!noNeedBg)
- {
- float start = progressPosX + mTextOffset / 2 + textWidth;
- mPaint.setColor(mUnReachedBarColor);
- mPaint.setStrokeWidth(mUnReachedProgressBarHeight);
- canvas.drawLine(start, 0, mRealWidth, 0, mPaint);
- }
- canvas.restore();
- }
- @Override
- protected void onSizeChanged(int w, int h, int oldw, int oldh)
- {
- super.onSizeChanged(w, h, oldw, oldh);
- mRealWidth = w - getPaddingRight() - getPaddingLeft();
- }
其实核心方法就是onDraw了，但是呢，onDraw也很简单，绘制线、绘制文本、绘制线，结束。
还有两个简单的辅助方法：
- /**
- * dp 2 px
- *
- * @param dpVal
- */
- protected int dp2px(int dpVal)
- {
- return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
- dpVal, getResources().getDisplayMetrics());
- }
- /**
- * sp 2 px
- *
- * @param spVal
- * @return
- */
- protected int sp2px(int spVal)
- {
- return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP,
- spVal, getResources().getDisplayMetrics());
- }
好了，到此我们的横向进度就结束了，是不是很简单~~如果你是自定义View，你还得考虑progress的更新，考虑状态的销毁与恢复等等复杂的东西。
接下来看我们的RoundProgressBarWidthNumber圆形的进度条。
2、RoundProgressBarWidthNumber
圆形的进度条和横向的进度条基本变量都是一致的，于是我就让RoundProgressBarWidthNumber extends HorizontalProgressBarWithNumber 了。
然后需要改变的就是测量和onDraw了：
完整代码：
- package com.zhy.view;
- import android.content.Context;
- import android.content.res.TypedArray;
- import android.graphics.Canvas;
- import android.graphics.Paint.Cap;
- import android.graphics.Paint.Style;
- import android.graphics.RectF;
- import android.util.AttributeSet;
- import com.zhy.library.view.R;
- public class RoundProgressBarWidthNumber extends
- HorizontalProgressBarWithNumber {
- /**
- * mRadius of view
- */
- private int mRadius = dp2px(30);
- public RoundProgressBarWidthNumber(Context context) {
- this(context, null);
- }
- public RoundProgressBarWidthNumber(Context context, AttributeSet attrs) {
- super(context, attrs);
- mReachedProgressBarHeight = (int) (mUnReachedProgressBarHeight * 2.5f);
- TypedArray ta = context.obtainStyledAttributes(attrs,
- R.styleable.RoundProgressBarWidthNumber);
- mRadius = (int) ta.getDimension(
- R.styleable.RoundProgressBarWidthNumber_radius, mRadius);
- ta.recycle();
- mTextSize = sp2px(14);
- mPaint.setStyle(Style.STROKE);
- mPaint.setAntiAlias(true);
- mPaint.setDither(true);
- mPaint.setStrokeCap(Cap.ROUND);
- }
- @Override
- protected synchronized void onMeasure(int widthMeasureSpec,
- int heightMeasureSpec) {
- int heightMode = MeasureSpec.getMode(heightMeasureSpec);
- int widthMode = MeasureSpec.getMode(widthMeasureSpec);
- int paintWidth = Math.max(mReachedProgressBarHeight,
- mUnReachedProgressBarHeight);
- if (heightMode != MeasureSpec.EXACTLY) {
- int exceptHeight = (int) (getPaddingTop() + getPaddingBottom()
- + mRadius * 2 + paintWidth);
- heightMeasureSpec = MeasureSpec.makeMeasureSpec(exceptHeight,
- MeasureSpec.EXACTLY);
- }
- if (widthMode != MeasureSpec.EXACTLY) {
- int exceptWidth = (int) (getPaddingLeft() + getPaddingRight()
- + mRadius * 2 + paintWidth);
- widthMeasureSpec = MeasureSpec.makeMeasureSpec(exceptWidth,
- MeasureSpec.EXACTLY);
- }
- super.onMeasure(heightMeasureSpec, heightMeasureSpec);
- }
- @Override
- protected synchronized void onDraw(Canvas canvas) {
- String text = getProgress() + "%";
- // mPaint.getTextBounds(text, 0, text.length(), mTextBound);
- float textWidth = mPaint.measureText(text);
- float textHeight = (mPaint.descent() + mPaint.ascent()) / 2;
- canvas.save();
- canvas.translate(getPaddingLeft(), getPaddingTop());
- mPaint.setStyle(Style.STROKE);
- // draw unreaded bar
- mPaint.setColor(mUnReachedBarColor);
- mPaint.setStrokeWidth(mUnReachedProgressBarHeight);
- canvas.drawCircle(mRadius, mRadius, mRadius, mPaint);
- // draw reached bar
- mPaint.setColor(mReachedBarColor);
- mPaint.setStrokeWidth(mReachedProgressBarHeight);
- float sweepAngle = getProgress() * 1.0f / getMax() * 360;
- canvas.drawArc(new RectF(0, 0, mRadius * 2, mRadius * 2), 0,
- sweepAngle, false, mPaint);
- // draw text
- mPaint.setStyle(Style.FILL);
- canvas.drawText(text, mRadius - textWidth / 2, mRadius - textHeight,
- mPaint);
- canvas.restore();
- }
- }
首先获取它的专有属性mRadius，然后根据此属性去测量，测量完成绘制；
绘制的过程呢？
先绘制一个细一点的圆，然后绘制一个粗一点的弧度，二者叠在一起就行。文本呢，绘制在中间~~~总体，没什么代码量。
好了，两个进度条就到这了，是不是发现简单很多。总体设计上，存在些问题，如果抽取一个BaseProgressBar用于获取公共的属性；然后不同样子的进度条继承分别实现自己的测量和样子，这样结构可能会清晰些~~~
