一款基于Material Desgin设计的APP
源码小编已经上传到github上了，求star啊
好久没写博客了，小编最近在研究Material Desgin（以下简称MD），话说现在市场的上App好多都用上了MD，先简单的介绍以下MD吧，它到底是个什么东东啊？
看看官方文档吧（中文版的呦）
官方解释说叫：原质化设计
小编也不懂什么叫原质化设计，我的理解就是遵循着用户体验的效果实现着一些让用户用起来舒适满意的动画效果及设计。怎么样这个够形象了吧，不看效果炫不炫，只看用户用着你的APP满意不满意。大体就是这样，就这样，小编追赶着时代的潮流也设计了一个属于自己的APP。它叫””（也可以叫它“淘学”哦）。

百度开发平台
看一下效果吧：
是一款基于MD的一款校园二手商品交易平台，当然小编只是简单的开发了一些功能，并没有完善，只是想做一款MD的APP，并没有交易支付的功能，只是把我感觉比较好的MD的一些组件融到了项目中，下面小编来详细介绍一下用到的技术：
因为小编服务器端不是很熟练，所以就用了，还不错挺容易上手的，就依赖了它的两个库而已，网络请求和模型都是封装好的，我们直接调用就可以。
先看一下小编引用的一些库吧：
compile 'com.android.support:appcompat-v7:23.1.0'
compile files('libs/BmobSDK_V3.4.5_1111.jar')
compile files('libs/okio-1.4.0.jar')
compile 'com.android.support:support-v4:23.1.0'
compile 'com.github.manuelpeinado.fadingactionbar:fadingactionbar-abc:3.1.2'
compile 'com.android.support:design:23.1.0'
compile 'com.pnikosis:materialish-progress:1.7'
compile 'me.drakeet.materialdialog:library:1.2.8'
compile 'com.jakewharton:butterknife:7.0.1'
compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'
compile 'com.weiwangcn.betterspinner:library:1.1.0'
compile 'com.nineoldandroids:library:2.4.0'
1.Android Support Desgin
CollapsingAvatarToolbar 头像随ListView滚动缩回到ActionBar特效
TextInputLayout带动画的输入框
2.ActionBarDrawerToggle、DrawerLayout、ActionBar 结合
3.RippleEffect水波纹效果
4.PagerSlidingTabStrip+viewpager实现选项卡左右滑动
5.FloatActiconButton悬浮按钮实现仿钉钉悬浮按钮
6.PullToZoomScrollView实现下拉自动放大头部View
7.materialdialog实现的对话框
8.MaterialSpinner实现的带效果的spinner
9.butterknife注解框架
小编用到的技术基本上就这些，下面小编会详细的介绍一下。
先介绍一下主界面吧，主界面小编用的是ActionBarDrawerToggle+DrawerLayout+ActionBar实现的滑动抽屉效果。布局文件就不介绍了，这个用的也挺多的，网上资料也很多，介绍几个方法吧
//设定左上角突变可点击
getSupportActionBar().setHomeButtonEnabled(true)
// 给左上角图标的左边加上一个返回的图标 。对应ActionBar.DISPLAY_HOME_AS_UP
getSupportActionBar().setDisplayHomeAsUpEnabled(true)
//设置标题 getSupportActionBar().setTitle(getResources().getString(R.string.action_title))
// 使自定义的普通View能在title栏显示，即actionBar.setCustomView能起作用，对应ActionBar.DISPLAY_SHOW_CUSTOM
actionBar.setDisplayShowCustomEnabled(true)
closeDrawers（）；//关闭抽屉
2.滑动选项卡
小编主界面的滑动选项卡用的是PagerSlidingTabStrip+viewpager管理fragment，详细用法大家可以看一下小编的这边博客：不详细介绍了。
3.主界面的悬浮按钮
悬浮按钮在github上有Demo，
小编用的是第一个，然后重写了一下里面的滑动监听实现了listview滑动显示隐藏按钮。看一下布局文件：
&com.hankkin.compustrading.view.floatbutton.FloatingActionsMenu
android:id="@+id/multiple_actions"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"

fab:fab_addButtonColorNormal="@color/origle"
fab:fab_addButtonColorPressed="@color/origle_tab"
fab:fab_addButtonPlusIconColor="@color/white"
fab:fab_labelStyle="@style/menu_labels_style"
android:layout_marginBottom="@dimen/smaller_space"
android:layout_marginRight="@dimen/smaller_space"
android:layout_marginEnd="@dimen/smaller_space"&
&com.hankkin.compustrading.view.floatbutton.FloatingActionButton
android:id="@+id/fb_update"
android:src="@drawable/update"

&com.hankkin.compustrading.view.floatbutton.FloatingActionButton
android:id="@+id/fb_new"
fab:paddingEnd="@dimen/small_space"
android:src="@drawable/edit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
fab:fab_colorNormal="@color/theme_color"
fab:fab_colorPressed="@color/theme_color_tab"/&
&com.hankkin.compustrading.view.floatbutton.FloatingActionButton
android:id="@+id/fb_person"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/title_person"
fab:fab_colorNormal="@color/theme_color"
fab:fab_colorPressed="@color/theme_color_tab"/&
&/com.hankkin.compustrading.view.floatbutton.FloatingActionsMenu&
下面是重写的ListView滑动监听实现显示隐藏悬浮按钮
public void attachToListView(@NonNull AbsListView listView,
ScrollDirectionListener scrollDirectionListener,
AbsListView.OnScrollListener onScrollListener) {
AbsListViewScrollDetectorImpl scrollDetector = new AbsListViewScrollDetectorImpl();
scrollDetector.setScrollDirectionListener(scrollDirectionListener);
scrollDetector.setOnScrollListener(onScrollListener);
scrollDetector.setListView(listView);
scrollDetector.setScrollThreshold(mScrollThreshold);
listView.setOnScrollListener(scrollDetector);
private class AbsListViewScrollDetectorImpl extends AbsListViewScrollDetector {
private ScrollDirectionListener mScrollDirectionL
private AbsListView.OnScrollListener mOnScrollL
private void setScrollDirectionListener(ScrollDirectionListener scrollDirectionListener) {
mScrollDirectionListener = scrollDirectionL
public void setOnScrollListener(AbsListView.OnScrollListener onScrollListener) {
mOnScrollListener = onScrollL
public void onScrollDown() {
if (mScrollDirectionListener != null) {
mScrollDirectionListener.onScrollDown();
public void onScrollUp() {
if (mScrollDirectionListener != null) {
mScrollDirectionListener.onScrollUp();
public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount,
int totalItemCount) {
if (mOnScrollListener != null) {
mOnScrollListener.onScroll(view, firstVisibleItem, visibleItemCount, totalItemCount);
super.onScroll(view, firstVisibleItem, visibleItemCount, totalItemCount);
public void onScrollStateChanged(AbsListView view, int scrollState) {
if (mOnScrollListener != null) {
mOnScrollListener.onScrollStateChanged(view, scrollState);
super.onScrollStateChanged(view, scrollState);
public void show() {
show(true);
public void hide() {
hide(true);
public void show(boolean animate) {
toggle(true, animate, false);
public void hide(boolean animate) {
toggle(false, animate, false);
private void toggle(final boolean visible, final boolean animate, boolean force) {
if (mVisible != visible || force) {
mVisible =
int height = getHeight();
if (height == 0 && !force) {
ViewTreeObserver vto = getViewTreeObserver();
if (vto.isAlive()) {
vto.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
public boolean onPreDraw() {
ViewTreeObserver currentVto = getViewTreeObserver();
if (currentVto.isAlive()) {
currentVto.removeOnPreDrawListener(this);
toggle(visible, animate, true);
return true;
int translationY = visible ? 0 : height + getMarginBottom();
if (animate) {
ViewPropertyAnimator.animate(this).setInterpolator(mInterpolator)
.setDuration(TRANSLATE_DURATION_MILLIS)
.translationY(translationY);
ViewHelper.setTranslationY(this, translationY);
if (!hasHoneycombApi()) {
setClickable(visible);
private int getMarginBottom() {
int marginBottom = 0;
final ViewGroup.LayoutParams layoutParams = getLayoutParams();
if (layoutParams instanceof ViewGroup.MarginLayoutParams) {
marginBottom = ((ViewGroup.MarginLayoutParams) layoutParams).bottomM
return marginB
private boolean hasHoneycombApi() {
return Build.VERSION.SDK_INT &= Build.VERSION_CODES.HONEYCOMB;
然后再activity中这样用：
fab.attachToListView(lvProduct, new ScrollDirectionListener() {
public void onScrollDown() {
Log.d("ListViewFragment", "onScrollDown()");
public void onScrollUp() {
Log.d("ListViewFragment", "onScrollUp()");
}, new AbsListView.OnScrollListener() {
public void onScrollStateChanged(AbsListView view, int scrollState) {
Log.d("ListViewFragment", "onScrollStateChanged()");
public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
Log.d("ListViewFragment", "onScroll()");
4.商品详细界面上下滑动头像回到actionbar上
这个效果是小编一直都想实现的，因为技术、时间、能力有限，所以一直没去搞，在网上搜了好多相关的帖子，博客，终于让我找到一个类似的，做了一下改动实现了。
这个技术是CoordinatorLayout+Toolbar+CollapsingAvatarToolbar实现的。实际上support desgin可以实现文字的上下滑动但是没有头像的上下滑动改变大小。CollapsingAvatarToolbar这个组件实现了这一效果，当然并不是小编写的，只是小编改的，但是能改出来小编也已经很高兴了。给大家看一下布局：

效果就这样：
5.个人资料界面
这个界面小编用的是PullToZoomScrollViewEx,github地址
用法也很简单，我们在布局里面嵌套一个PullToZoomScrollViewEx，而布局的head，content，footer都可以自定义，然后引用进来就可以了。
PullToZoomScrollViewEx scrollView = (PullToZoomScrollViewEx) findViewById(R.id.my_pull_scoll)
headView = LayoutInflater.from(this).inflate(R.layout.profile_head_view, null, false)
zoomView = LayoutInflater.from(this).inflate(R.layout.profile_zoom_view, null, false)
contentView = LayoutInflater.from(this).inflate(R.layout.profile_contect_view, null, false)
scrollView.setHeaderView(headView)
scrollView.setZoomView(zoomView)
scrollView.setScrollContentView(contentView)
其他的注解、dialog等小编在这里就不介绍了，很多资料，小编把网址给大家贴下来，有兴趣的可以看一下：
APP有很多不合理的地方，还请小伙伴们多多包涵哈，多多指正，源码估计元旦回去之后等我完善之后会开源出来的，大家可以多多关注我的博客和，要是有的小伙伴等不及可以留下邮箱，我会及时关注给你们发源码的。

这个技术是CoordinatorLayout+Toolbar+CollapsingAvatarToolbar实现的。实际上support desgin可以实现文字的上下滑动但是没有头像的上下滑动改变大小。CollapsingAvatarToolbar这个组件实现了这一效果，当然并不是小编写的，只是小编改的，但是能改出来小编也已经很高兴了。给大家看一下布局：

效果就这样：
5.个人资料界面
这个界面小编用的是PullToZoomScrollViewEx,github地址
用法也很简单，我们在布局里面嵌套一个PullToZoomScrollViewEx，而布局的head，content，footer都可以自定义，然后引用进来就可以了。
PullToZoomScrollViewEx scrollView = (PullToZoomScrollViewEx) findViewById(R.id.my_pull_scoll)
headView = LayoutInflater.from(this).inflate(R.layout.profile_head_view, null, false)
zoomView = LayoutInflater.from(this).inflate(R.layout.profile_zoom_view, null, false)
contentView = LayoutInflater.from(this).inflate(R.layout.profile_contect_view, null, false)
scrollView.setHeaderView(headView)
scrollView.setZoomView(zoomView)
scrollView.setScrollContentView(contentView)
其他的注解、dialog等小编在这里就不介绍了，很多资料，小编把网址给大家贴下来，有兴趣的可以看一下：
APP有很多不合理的地方，还请小伙伴们多多包涵哈，多多指正，源码估计元旦回去之后等我完善之后会开源出来的，大家可以多多关注我的博客和，要是有的小伙伴等不及可以留下邮箱，我会及时关注给你们发源码的。
