Android 中实现ListView滑动隐藏标题栏的代码
布局中listview要覆盖标题栏
int mTouchSlop = ViewConfiguration.get(this).getScaledTouchSlop(); //滑动监听 showHideTitleBar(true);
ListView standby_lv = (ListView) findViewById(R.id.standby_lv); standby_lv.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { switch (event.getAction()) { case MotionEvent.ACTION_DOWN: mFirstY = event.getY(); break; case MotionEvent.ACTION_MOVE: mCurrentY = event.getY(); if (mCurrentY - mFirstY > mTouchSlop) { // 下滑 显示titleBar showHideTitleBar(true); } else if (mFirstY - mCurrentY > mTouchSlop) { // 上滑 隐藏titleBar showHideTitleBar(false); } break; case MotionEvent.ACTION_UP: break; } return false; } });
private Animator mAnimatorTitle; private Animator mAnimatorTitlePage; private Animator mAnimatorContent; private void showHideTitleBar(boolean tag) { if (mAnimatorTitle != null && mAnimatorTitle.isRunning()) { mAnimatorTitle.cancel(); } if (mAnimatorTitlePage != null && mAnimatorTitlePage.isRunning()) { mAnimatorTitlePage.cancel(); } if (mAnimatorContent != null && mAnimatorContent.isRunning()) { mAnimatorContent.cancel(); } if (tag) { mAnimatorTitle = ObjectAnimator.ofFloat(mTitle, "translationY", mTitle.getTranslationY(), 0); mAnimatorTitlePage = ObjectAnimator.ofFloat(mTitlePage, "translationY", mTitlePage.getTranslationY(), 0); mAnimatorContent = ObjectAnimator.ofFloat(standby_lv, "translationY", standby_lv.getTranslationY(), getResources().getDimension(R.dimen.title_height)); } else { mAnimatorTitle = ObjectAnimator.ofFloat(mTitle, "translationY", mTitle.getTranslationY(), -mTitle.getHeight()); mAnimatorTitlePage = ObjectAnimator.ofFloat(mTitlePage, "translationY", mTitlePage.getTranslationY(), -mTitlePage.getHeight()); mAnimatorContent = ObjectAnimator.ofFloat(standby_lv, "translationY", standby_lv.getTranslationY(), 0); } mAnimatorTitle.start(); mAnimatorTitlePage.start(); mAnimatorContent.start(); }
dimen.xml文件
<dimen name="titlepage_height">45dp</dimen>
