Android 中實現ListView滑動隱藏標題欄的代碼

布局中listview要覆蓋標題欄

 int mTouchSlop = ViewConfiguration.get(this).getScaledTouchSlop();
//滑動監聽
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 顯示titleBar
       showHideTitleBar(true);
      } else if (mFirstY - mCurrentY > mTouchSlop) {
       // 上滑 隱藏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>
