一、CardView
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="20dp"
app:cardCornerRadius="5dp"
app:cardBackgroundColor="@color/colorPaiGowYellow">
- 誤區(qū):設(shè)置背景顏色,沒有圓角
android:background="@color/colorPaiGowYellow"
mCardView.setBackgroundColor="getResources().getColor(R.color.colorPaiGowYellow)";
- 解決:設(shè)置控件背景
app:cardBackgroundColor="@color/colorPaiGowYellow"
mCardView.setCardBackgroundColor(getResources().getColor(R.color.colorPaiGowYellow));
二、FloatingActionButton
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:src="@drawable/ic_comment"
app:layout_anchor="@id/appBar"
app:layout_anchorGravity="bottom|end"/>
<!--Fab大小設(shè)置-->
<dimen name="design_fab_size_normal" tools:ignore="PrivateResource">80dp</dimen>
<!--Fab中間Icon大小設(shè)置-->
<dimen name="design_fab_image_size" tools:override="true">60dp</dimen>
- 具有立體感,和普通按鈕功能一樣
三、CircleImageView
<de.hdodenhof.circleimageview.CircleImageView
android:src="@drawable/image11"
android:layout_centerInParent="true"
android:id="@+id/icon_image"
android:layout_width="70dp"
android:layout_height="70dp" />
- 圓形圖片,常用于顯示頭像
四、DrawerLayout 、NavigationView
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/img_frame_background"
tools:context="com.example.lenovo_g50_70.materialdesign.MainActivity">
<!--側(cè)滑左布局-->
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
android:tag="START"
app:headerLayout="@layout/nav_header"
app:menu="@menu/nav_menu"/>
<!--側(cè)滑右布局-->
<android.support.design.widget.NavigationView
android:id="@+id/nav_rightview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="end"
android:tag="END"
app:headerLayout="@layout/nav_header"
app:menu="@menu/nav_menu"/>
</android.support.v4.widget.DrawerLayout>
- 允許加入兩個(gè)子控件,分別是側(cè)滑菜單和主布局
- NavigationView:常用于側(cè)滑菜單的根布局
- 提供更好的側(cè)滑菜單展示效果(nineoldandroids-2.4.0.jar)
drawerLayout.setDrawerListener(new DrawerLayout.DrawerListener() {
@Override
public void onDrawerSlide(View drawerView, float slideOffset) {//監(jiān)聽菜單滑動時(shí)的動畫效果
View mContent = drawerLayout.getChildAt(0);
View mMenu = drawerView;
float scale = 1 - slideOffset;
float rightScale = 0.8f + scale * 0.2f;
//Tag,用于給相關(guān)聯(lián)的view添加額外的信息
if (drawerView.getTag().equals("START"))
{ //左側(cè)滑欄
float leftScale = 1 - 0.3f * scale;
ViewHelper.setScaleX(mMenu, leftScale);
ViewHelper.setScaleY(mMenu, leftScale);
ViewHelper.setAlpha(mMenu, 0.6f + 0.4f * (1 - scale));
ViewHelper.setTranslationX(mContent, mMenu.getMeasuredWidth() * (1 - scale));
ViewHelper.setPivotX(mContent, 0);
ViewHelper.setPivotY(mContent, mContent.getMeasuredHeight() / 2);
mContent.invalidate();
ViewHelper.setScaleX(mContent, rightScale);
ViewHelper.setScaleY(mContent, rightScale);
} else { //右側(cè)滑欄
ViewHelper.setTranslationX(mContent, -mMenu.getMeasuredWidth() * slideOffset);
ViewHelper.setPivotX(mContent, mContent.getMeasuredWidth());
ViewHelper.setPivotY(mContent, mContent.getMeasuredHeight() / 2);
mContent.invalidate();
ViewHelper.setScaleX(mContent, rightScale);
ViewHelper.setScaleY(mContent, rightScale);
}
}
五、SwipeRefreshLayout
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipe_refresh"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
</android.support.v4.widget.SwipeRefreshLayout>
- 下拉刷新,常作為View的根布局,刷新子View的內(nèi)容
- 第三方依賴,支持下拉刷新和上拉加載
<com.liaoinstan.springview.widget.SpringView
android:id="@+id/spring_news"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_news"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</com.liaoinstan.springview.widget.SpringView>
六、CoordinatorLayout 、AppBarLayout 、NestedScrollView 、CollapsingToolbarLayout、Toolbar
CoordinatorLayout是增強(qiáng)版FrameLayout,AppBarLayout是增強(qiáng)版LinearLayout,NestedScrollView是增強(qiáng)版ScrollView,Toolbar是增強(qiáng)版ActionBar,CollapsingToolbarLayout是一個(gè)支持折疊并且?guī)в袃?yōu)美的動畫漸變效果的Layout 。
Toolbar一般作為CollapsingToolbarLayout的直接子布局,CollapsingToolbarLayout一般作為AppBarLayout的直接子布局,AppBarLayout一般作為CoordinatorLayout的直接子布局
CoordinatorLayout的子布局實(shí)現(xiàn)屬性app:layout_behavior="@string/appbar_scrolling_view_behavior",將滑動事件通知AppBarLayout,使AppBarLayout作出相應(yīng)的動作。
AppBarLayout的子布局實(shí)現(xiàn)屬性app:layout_scrollFlags,其中scroll表示AppBarLayout的ChildView 跟隨滑動事件滑進(jìn)或滑出屏幕 , 滑動的前提是當(dāng)前的ChildView 前的ChildView也設(shè)置了scroll 屬性,enterAlways 表示快速返回模式,則ChildView的滑動優(yōu)先級大于AppBarLayout外的View,enterAlwaysCollapsed作為enterAlways的附加屬性,需要結(jié)合android:minHeight和enterAlways 一起使用,表示 ChildView先滑動minHeight的距離,然后讓AppBarLayout外的View完成滑動,再滑動ChildView剩下的距離,exitUntilCollapsed 設(shè)置了該屬性的ChildView滑出屏幕后,如果其后面的ChildView沒設(shè)置該屬性,則不能滑出屏幕,snap是ChildView滑動的一個(gè)吸附效果,不會存在局部滑動的情況,在屏幕中整個(gè)顯示或者整個(gè)隱藏 。
CollapsingToolbarLayout的子布局實(shí)現(xiàn)屬性app:layout_collapseMode,其中off是默認(rèn)屬性,表示沒有折疊的行為,pin表示CollapsingToolbarLayout折疊后,設(shè)置該屬性的ChildView將固定在頂部,parallax表示CollapsingToolbarLayout折疊時(shí),此布局會有視差折疊效果,CollapsingToolbarLayout自己實(shí)現(xiàn)屬性app:contentScrim="?attr/colorPrimary",表示趨于折疊狀態(tài)以及折疊后的背景顏色 。
<!--主布局-->
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_girl"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.example.lenovo_g50_70.materialdesign.GirlActivity">
<android.support.design.widget.AppBarLayout
android:id="@+id/appBar"
android:fitsSystemWindows="true"
android:layout_width="match_parent"
android:layout_height="530dp">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/girl_image_view"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax"/>
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:id="@+id/ToolBar"
app:layout_collapseMode="pin"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardCornerRadius="4dp">
<TextView
android:id="@+id/girl_content_text"
android:layout_margin="10dp"
android:textSize="20sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</android.support.v7.widget.CardView>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
七、Snackbar
可與用戶實(shí)現(xiàn)交互,可比作增強(qiáng)版的Toast
Snackbar.make(v,"Data delete",Snackbar.LENGTH_INDEFINITE)
.setAction("Undo", new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this,"Data restored",Toast.LENGTH_SHORT).show();
}
}).show();
八、TextInputLayout
包裹EditText,展示更豐富的提示效果
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_marginBottom="8dp"
android:background="@android:color/white"
android:textColorHint="@color/colorPrimary"
app:counterEnabled="true"
app:counterMaxLength="19"
app:counterOverflowTextAppearance="@color/colorPrimary"
app:hintTextAppearance="@color/colorPrimary">
<EditText
android:imeOptions="actionNext"
android:id="@+id/log_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="5dp"
android:background="@null"
android:hint="用戶名"/>
</android.support.design.widget.TextInputLayout>
九、BottomNavigationView
<android.support.design.widget.BottomNavigationView
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_alignParentBottom="true"
android:background="?android:attr/windowBackground"
app:itemBackground="@null" -> 取消導(dǎo)航欄的點(diǎn)擊效果
app:itemIconTint="@color/colorPrimary"
app:itemTextColor="@color/colorPrimary"
app:menu="@menu/navigation" />
底部Item菜單
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:icon="@mipmap/ic_launcher"
android:title="首頁" />
<item
android:icon="@mipmap/ic_launcher"
android:title="收藏" />
<item
android:icon="@mipmap/ic_launcher"
android:title="我的" />
</menu>
當(dāng)菜單數(shù)目大于三時(shí),會有位移動畫,可以通過反射取消該動畫
@SuppressLint("RestrictedApi")
public static void disableShiftMode(BottomNavigationView view) {
BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0);
try {
Field shiftingMode = menuView.getClass().getDeclaredField("mShiftingMode");
shiftingMode.setAccessible(true);
shiftingMode.setBoolean(menuView, false);
shiftingMode.setAccessible(false);
for (int i = 0; i < menuView.getChildCount(); i++) {
BottomNavigationItemView item = (BottomNavigationItemView) menuView.getChildAt(i);
item.setShiftingMode(false);
item.setChecked(item.getItemData().isChecked());
}
} catch (Exception e) {
}
}
取消導(dǎo)航欄的每項(xiàng)點(diǎn)擊文字和圖片放大的效果
<dimen name="design_bottom_navigation_active_text_size">10dp</dimen>
<dimen name="design_bottom_navigation_text_size">10dp</dimen>
十、啟動頁優(yōu)化
public class SplashActivity extends AppCompatActivity {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
finish();
}
}
<activity
android:name=".ui.activity.SplashActivity"
android:theme="@style/SplashTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
<item name="android:windowBackground">@drawable/splash_layer</item>
</style>
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:drawable="@color/colorPrimary"/>
<item>
<bitmap
android:gravity="center"
android:src="@mipmap/ic_launcher"/>
</item>
</layer-list>
