先看下我们测试人员提的bug票：

Change-Id: Ia5e914cd905d27baeccfa7d30b9f6eac9e00b041
TracID: 565
DESC: Press the up&down icon(△&▽) quickly (Use two fingers),The up&down icon(△&▽) disappear.
Analysis: Press up&down icon(△&▽) have a time interval,so you shouldn't be interrupt.
Solution: remove qbja2/frameworks/base/core/java/android/widget/NumberPicker.java "mShowInputControlsAnimator.cancel();"

修改代码如下：
@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
if (!isEnabled() || !mFlingable) {
return false;
}
switch (event.getActionMasked()) {
case MotionEvent.ACTION_DOWN:
mLastMotionEventY = mLastDownEventY = event.getY();
removeAllCallbacks();
//mShowInputControlsAnimator.cancel(); 这里注释掉就解决了
mBeginEditOnUpEvent = false;
mAdjustScrollerOnUpEvent = true;
if (mDrawSelectorWheel) {
boolean scrollersFinished = mFlingScroller.isFinished()
&& mAdjustScroller.isFinished();
if (!scrollersFinished) {
mFlingScroller.forceFinished(true);
mAdjustScroller.forceFinished(true);
onScrollStateChange(OnScrollListener.SCROLL_STATE_IDLE);
}
mBeginEditOnUpEvent = scrollersFinished;
mAdjustScrollerOnUpEvent = true;
hideInputControls();
return true;
}
if (isEventInViewHitRect(event, mInputText)
|| (!mIncrementButton.isShown()
&& isEventInViewHitRect(event, mIncrementButton))
|| (!mDecrementButton.isShown()
&& isEventInViewHitRect(event, mDecrementButton))) {
mAdjustScrollerOnUpEvent = false;
setDrawSelectorWheel(true);
hideInputControls();
return true;
}
break;
case MotionEvent.ACTION_MOVE:
float currentMoveY = event.getY();
int deltaDownY = (int) Math.abs(currentMoveY - mLastDownEventY);
if (deltaDownY > mTouchSlop) {
mBeginEditOnUpEvent = false;
onScrollStateChange(OnScrollListener.SCROLL_STATE_TOUCH_SCROLL);
setDrawSelectorWheel(true);
hideInputControls();
return true;
}
break;
}
return false;
}
