android ios 唱歌/K歌评分代码sdk
2、安卓SDK实验室那边会给到.aar库，而IOS会给到.库，通过正常方法引入库到我们项目后，即可进行下一步对接
public class CustomView extends ScoreBasicView {private Paint mPaint;private int mHitPos = -1;public CustomView(Context context) {super(context);mPaint = new Paint();mPaint.setStrokeWidth(getBlockHeight());mPaint.setStrokeCap(Paint.Cap.ROUND);}public CustomView(Context context, AttributeSet attrs) {super(context, attrs);mPaint = new Paint();mPaint.setStrokeWidth(getBlockHeight());mPaint.setStrokeCap(Paint.Cap.ROUND);}/*** 设置打分圆点偏移像素** @return*/@Overridepublic int getXOffsetPx() {return 300;}/*** 设置每像素多少毫秒（决定打分曲线每段长度）** @return*/@Overridepublic int getMsPrePx() {return 2;}/*** 设置打分曲线高度** @return*/@Overridepublic int getBlockHeight() {return 12;}/*** 设置录音延时** @return*/@Overridepublic int getRecordDelay() {return Constants.WAVE_DELAY_CUL;}/*** 自定义绘制** @param canvas 画布* @param offsetx 整体曲线向左移动像素值* @param hitCusorY 打分圆点y值高度* @param standers 标准曲线列表* @param recordMap 录音信息Map* @return false使用默认绘制，true使用自定义绘制*/@Overridepublic boolean onCustomDraw(Canvas canvas, int offsetx, int hitCusorY, int maxPos,ArrayList<ScoreInfo> standers, HashMap<Integer, ArrayList<ScoreInfo>> recordMap) {this.mPaint.setColor(-533482011);int height = getMeasuredHeight();int blockHeight = getBlockHeight();canvas.drawRect(0.0F, 0.0F, (float) this.getXOffsetPx(), height, this.mPaint);drawPitchBlock(canvas, recordMap, standers, offsetx);this.mPaint.setColor(-48060);float eve = 1.0f * (height - blockHeight) / maxPos;if (mHitPos == -1) {if (maxPos != 0) {mHitPos = (int) (blockHeight / 2.0 + (maxPos - 1) * eve);} else {mHitPos = (int) (height - blockHeight / 2.0);}}if (hitCusorY == -1) {mHitPos += height / 10;int maxH = (int) (blockHeight / 2.0 + (maxPos - 1) * eve);if (mHitPos > maxH) {mHitPos = maxH;}} else {mHitPos = hitCusorY;}canvas.drawCircle(getXOffsetPx(), mHitPos, blockHeight / 2f, mPaint);return true;}/*** 绘制标准文件线段** @param canvas canvas*/private void drawPitchBlock(Canvas canvas, HashMap<Integer, ArrayList<ScoreInfo>> recMap, ArrayList<ScoreInfo> stand, int offset) {boolean need = false;for (int i = 0, size = stand.size(); i < size; ++i) {ScoreInfo stander = stand.get(i);int x1 = stander.drawRect[0] - offset;int x2 = stander.drawRect[1] - offset;int y = stander.drawRect[2];if (isNeedDraw(x1, x2)) {mPaint.setColor(Color.LTGRAY);need = true;canvas.drawLine(x1, y, x2, y, mPaint);if (recMap.containsKey(i)) {boolean need2 = false;List<ScoreInfo> words = recMap.get(i);mPaint.setColor(Color.RED);for (ScoreInfo word : words) {int xx1 = word.drawRect[0] - offset;int xx2 = word.drawRect[1] - offset;int yy = word.drawRect[2];if (isNeedDraw(xx1, xx2)) {need2 = true;if (y == yy && intersects(x1, x2, xx1, xx2)) {canvas.drawLine(Math.max(xx1, x1), yy, Math.min(xx2, x2), yy, mPaint);}} else if (need2) {break;}}}} else if (need) {break;}}}private boolean intersects(int x1, int x2, int xx1, int xx2) {return x1 < xx2 && xx1 < x2;}/*** 判断是否需要绘制这部分区域** @param var1 区域的左边* @param var2 区域的右边* @return*/private boolean isNeedDraw(int var1, int var2) {return !(var1 >= getWidth() || var2 <= 0);}
}
4、接着我们把录音数据传进控件，即可实现评分啦，是不是很方便呢
mCustomView.feedRecordBuffer(rec, rec.length, ms, isFeakTime);
5、如果说“可是录音数据哪来啊？我们也不会弄音视频相关的”，那么请放心，云歌实验室还提供----音频能力库，
方便大家轻松上手，见《云歌音频库》
