如何在触摸事件中隐藏或显示操作栏

Question

我在这里使用视图寻呼机设置onTouchListner。

我想在View Viewr上进行简单点击时，它应隐藏或显示操作栏和其他布局，并在再次触摸时显示它们。我还想使用Sliding effect视图寻呼机。

这是我到目前为止所做的。

viewPager.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            onTouchEvent(event);
            return false;
        }
    });

public boolean onTouchEvent(MotionEvent event) {
    switch (event.getAction()) {   
    case MotionEvent.ACTION_DOWN: {
        downX = event.getX();
        downY = event.getY();
        return true;
    }
    case MotionEvent.ACTION_UP: {
        upX = event.getX();
        upY = event.getY();
        float deltaX = downX - upX;
        float deltaY = downY - upY;
        // swipe horizontal?
        if (Math.abs(deltaX) > MIN_DISTANCE) {
            // left or right
            if (deltaX < 0) {
                Toast("Left to right");
                openPreviousPage();
                return true;
            }
            if (deltaX > 0) {
                Toast("ight to left");
                openNextPage();
                return true;
            }
        } else {
            if (Math.abs(deltaX) < 15) {
                toggleFullScreen();
            }

        }

        return true;
    }
    }
    return false;
}

使用SystemUiHider隐藏操作栏和其他布局。

以下是我要隐藏的内容

mSystemUiHider = SystemUiHider.getInstance(this, bottomRL, HIDER_FLAGS);
    mSystemUiHider.setup();

mSystemUiHider
            .setOnVisibilityChangeListener(new SystemUiHider.OnVisibilityChangeListener() {
                // Cached values.
                int mControlsHeight;
                int mShortAnimTime;

                @Override
                @TargetApi(Build.VERSION_CODES.HONEYCOMB_MR2)
                public void onVisibilityChange(boolean visible) {
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
                        // If the ViewPropertyAnimator API is available
                        // (Honeycomb MR2 and later), use it to animate the
                        // in-layout UI controls at the bottom of the
                        // screen.
                        if (mControlsHeight == 0) {
                            mControlsHeight = bottomRL.getHeight();
                        }
                        if (mShortAnimTime == 0) {
                            mShortAnimTime = getResources().getInteger(
                                    android.R.integer.config_shortAnimTime);
                        }
                        bottomRL.animate()
                                .translationY(visible ? 0 : mControlsHeight)
                                .setDuration(mShortAnimTime);
                    } else {
                        if (visible) {
                            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
                                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                                    RelativeLayout.LayoutParams.WRAP_CONTENT);
                            params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
                            bottomRL.setLayoutParams(params);
                            bottomRL.setVisibility(View.VISIBLE);
                            // getActionBar().show();
                        } else {
                            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
                                    RelativeLayout.LayoutParams.MATCH_PARENT,
                                    RelativeLayout.LayoutParams.MATCH_PARENT);
                            params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
                            viewPager.setLayoutParams(params);
                            getActionBar().hide();
                            viewPager.setVisibility(View.GONE);
                        }
                    }
                    if (visible) {
                        // Schedule a hide().
                        // delayedHide(AUTO_HIDE_DELAY_MILLIS);
                    }
                }
            });

问题在于，当我触摸查看寻呼机时，它会隐藏操作栏和其他布局，即现在我处于全屏模式。但是现在，如果我尝试滑动视图寻呼机，它首先显示操作栏，然后在滑动后滑动到下一个屏幕

请帮助我解决这个问题。 提前谢谢。
