AndroidTagGroup實作雲标簽效果，各種背景效果的标簽，并且支援添加，

大體實作：有一個TagsManager管理TagGroup，自定義TagGroup，對TagGroup設定setTags(tags);

TagGroup extends ViewGroup，TagGroup 由多個TagView組成，TagView繼承TextView 。

主要繪制代碼如下：

@Override

protected void onDraw(Canvas canvas) {

canvas.drawArc(mLeftCornerRectF, -180, 90, true, mBackgroundPaint);

canvas.drawArc(mLeftCornerRectF, -270, 90, true, mBackgroundPaint);

canvas.drawArc(mRightCornerRectF, -90, 90, true, mBackgroundPaint);

canvas.drawArc(mRightCornerRectF, 0, 90, true, mBackgroundPaint);

canvas.drawRect(mHorizontalBlankFillRectF, mBackgroundPaint);

canvas.drawRect(mVerticalBlankFillRectF, mBackgroundPaint);

if (isChecked) {

canvas.save();

canvas.rotate(45, mCheckedMarkerBound.centerX(), mCheckedMarkerBound.centerY());

canvas.drawLine(mCheckedMarkerBound.left, mCheckedMarkerBound.centerY(),

mCheckedMarkerBound.right, mCheckedMarkerBound.centerY(), mCheckedMarkerPaint);

canvas.drawLine(mCheckedMarkerBound.centerX(), mCheckedMarkerBound.top,

mCheckedMarkerBound.centerX(), mCheckedMarkerBound.bottom, mCheckedMarkerPaint);

canvas.restore();

}

canvas.drawPath(mBorderPath, mBorderPaint);

super.onDraw(canvas);

}
