Android 中实现ListView滑动隐藏标题栏的代码
作者：Wo来给你讲故事
本文通过实例代码给大家分享了android listview滑动隐藏标题栏的方法，代码简单易懂，需要的朋友参考下
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>
