黑胶唱片专辑封面绘制流程
@Override
protected void onDraw(Canvas canvas) {
// 1.绘制顶部虚线
mTopLine.setBounds(0, 0, getWidth(), mTopLineHeight);
mTopLine.draw(canvas);
// 2.绘制黑胶唱片外侧半透明边框
mCoverBorder.setBounds(mDiscPoint.x - mCoverBorderWidth, mDiscPoint.y - mCoverBorderWidth,
mDiscPoint.x + mDiscBitmap.getWidth() + mCoverBorderWidth, mDiscPoint.y +
mDiscBitmap.getHeight() + mCoverBorderWidth);
mCoverBorder.draw(canvas);
// 3.绘制黑胶
// 设置旋转中心和旋转角度,setRotate和preTranslate顺序很重要
mDiscMatrix.setRotate(mDiscRotation, mDiscCenterPoint.x, mDiscCenterPoint.y);
// 设置图片起始坐标
mDiscMatrix.preTranslate(mDiscPoint.x, mDiscPoint.y);
canvas.drawBitmap(mDiscBitmap, mDiscMatrix, null);
// 4.绘制封面
mCoverMatrix.setRotate(mDiscRotation, mCoverCenterPoint.x, mCoverCenterPoint.y);
mCoverMatrix.preTranslate(mCoverPoint.x, mCoverPoint.y);
canvas.drawBitmap(mCoverBitmap, mCoverMatrix, null);
// 5.绘制指针
mNeedleMatrix.setRotate(mNeedleRotation, mNeedleCenterPoint.x, mNeedleCenterPoint.y);
mNeedleMatrix.preTranslate(mNeedlePoint.x, mNeedlePoint.y);
canvas.drawBitmap(mNeedleBitmap, mNeedleMatrix, null);
}
歌词绘制流程
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
// 中心Y坐标
float centerY = getHeight() / 2 + mTextSize / 2 + mAnimOffset;
// 无歌词文件
if (!hasLrc()) {
float centerX = (getWidth() - mCurrentPaint.measureText(label)) / 2;
canvas.drawText(label, centerX, centerY, mCurrentPaint);
return;
}
// 画当前行
String currStr = mLrcTexts.get(mCurrentLine);
float currX = (getWidth() - mCurrentPaint.measureText(currStr)) / 2;
canvas.drawText(currStr, currX, centerY, mCurrentPaint);
// 画当前行上面的
for (int i = mCurrentLine - 1; i >= 0; i--) {
String upStr = mLrcTexts.get(i);
float upX = (getWidth() - mNormalPaint.measureText(upStr)) / 2;
float upY = centerY - (mTextSize + mDividerHeight) * (mCurrentLine - i);
// 超出屏幕停止绘制
if (upY - mTextSize < 0) {
break;
}
canvas.drawText(upStr, upX, upY, mNormalPaint);
}
// 画当前行下面的
for (int i = mCurrentLine + 1; i < mLrcTimes.size(); i++) {
String downStr = mLrcTexts.get(i);
float downX = (getWidth() - mNormalPaint.measureText(downStr)) / 2;
float downY = centerY + (mTextSize + mDividerHeight) * (i - mCurrentLine);
// 超出屏幕停止绘制
if (downY > getHeight()) {
break;
}
canvas.drawText(downStr, downX, downY, mNormalPaint);
}
}
