效果还不错，整体上是Translate动画和FrameLayout布局的结合，下面看一下代码:activiy_main.xml```xml <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" >

<FrameLayout   android:layout_width="match_parent"   android:layout_height="wrap_content" >    <TextView       android:id="@+id/toast"       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:layout_gravity="center"       android:layout_marginBottom="20dp"       android:layout_marginTop="40dp"       android:background="@color/transparent_black"       android:gravity="center"       android:paddingBottom="5dp"       android:paddingLeft="40dp"       android:paddingRight="40dp"       android:paddingTop="5dp"       android:text="@string/toast"       android:textColor="@color/white"       android:textSize="16sp"       android:visibility="invisible" />    <TextView       android:id="@+id/title"       android:layout_width="match_parent"       android:layout_height="wrap_content"       android:background="@color/blue"       android:gravity="center"       android:padding="5dp"       android:text="@string/title"       android:textColor="@color/white"       android:textSize="20sp" /></FrameLayout><TextView   android:id="@+id/info"   android:layout_width="match_parent"   android:layout_height="wrap_content"   android:layout_marginTop="10dp"   android:gravity="center"   android:text="@string/hello_world" /><Button   android:id="@+id/btn"   android:layout_width="match_parent"   android:layout_height="wrap_content"   android:layout_marginTop="30dp"   android:gravity="center"   android:text="@string/btn" ></Button>

</LinearLayout>
