Android开发之Android 5.0新特性

2015谷歌开发者大会的召开，将Android推向了一个新的时代！ Android 5.0的推出更是大会的一大亮点，在此次大会中， Android推出了许多的新控件，下面我们看看都有什么： android.support.v4.widget.DrawerLayout(经常作为整个布局的终极父类)
android.support.design.widget.CoordinatorLayout(控件协调器)
android.support.design.widget.AppBarLayout(状态栏)
android.support.v7.widget.Toolbar(与AppBarLayout结合使用，指针widget)
android.support.design.widget.NavigationView(类似于抽屉)
android.support.design.widget.CollapsingToolbarLayout(顾名思义，折叠ToolBar)
android.support.v4.widget.NestedScrollView
android.support.v7.widget.CardView(卡片类控件)
android.support.design.widget.FloatingActionButton(炫酷的悬浮按钮)
android.support.v4.widget.SwipeRefreshLayout(下拉刷新)
android.support.v7.widget.RecyclerView(替代ListView，GridView的不二控件)
android.support.design.widget.TextInputLayout(与EditText控件结合使用，效果炫酷)
经过本人一段时间的研究，现已将所用控件集成到了一个Demo中，下面废话少说，直接贴代码了，还望诸位大神批评指正，灰常感谢♪(^∇^*)
特别注意： 本Demo中还集成使用了一些开源库： 1.圆形图片 使用方法： <de.hdodenhof.circleimageview.CircleImageView
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/profile_image"
    android:layout_width="96dp"
    android:layout_height="96dp"
    android:src="@drawable/profile"
    app:border_width="2dp"
    app:border_color="#FF000000"/>
添加类库支持： 在module的build.gradle中添加类库支持 compile 'de.hdodenhof:circleimageview:1.3.0'
2.图片加载框架 使用方法： Glide.with(this).load(“url或者是drawable下的图片”).into(imageView)
添加类库支持： 在module的build.gradle中添加类库支持compile 'com.github.bumptech.glide:glide:3.6.0'
3.Activity炫酷跳转框架：使用方法：a.Start Activity in first activity.

findViewById(R.id.imageView).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        final Intent intent = new Intent(MainActivity.this, SubActivity.class);
        ActivityTransitionLauncher.with(MainActivity.this).from(v).launch(intent);
    }
});
b.Receive intent in second activity.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sub);
        ActivityTransition.with(getIntent()).to(findViewById(R.id.sub_imageView)).start(savedInstanceState);
    }
c.If you want the exit animation, you can do like this.

    private ExitActivityTransition exitTransition;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sub2);
        exitTransition =      ActivityTransition.with(getIntent()).to(findViewById(R.id.sub_imageView)).start(savedInstanceState);
    }
    @Override
    public void onBackPressed() {
        exitTransition.exit(this);
    }

添加类库支持：在module的build.gradle中添加类库支持compile 'com.kogitune:pre-lollipop-activity-transition:1.0.0'
4.特别注意事项：   使用Android 5.0中的控件，必须在module的build.gradle中添加类库支持compile 'com.android.support:design:22.2.0'
本Demo中的module.gradle的dependencies如下：
dependencies {
                          compile fileTree(include: ['*.jar'], dir: 'libs')
                          compile 'com.android.support:appcompat-v7:22.2.0'
                          compile 'com.android.support:design:22.2.0'
                          compile 'com.android.support:recyclerview-v7:22.2.0'
                          compile 'com.android.support:cardview-v7:22.2.0'
                          compile 'de.hdodenhof:circleimageview:1.3.0'
                          compile 'com.github.bumptech.glide:glide:3.6.0'
                          compile 'com.telly:floatingaction:0.0.4'
                          compile 'com.kogitune:pre-lollipop-activity-transition:1.0.0'
}
