Android 实现在控件下面滑出式的菜单栏

来源：互联网发布：qq游戏端口是多少编辑：程序博客网时间：2024/04/30 23:13

最近项目有一个需求，要做一个类似于popupwindow 弹出式的菜单栏，但是和popup不同的是，要从触发view的下面“滑”出来，因为popup是位于屏幕最上层的

所以从view下面滑出这个效果就无法实现了

最后想出的方案是在布局文件中提前写好菜单栏，然后使用给布局文件设置动画的方式来实现该效果

代码如下

布局文件

<LinearLayout    android:id="@+id/ll_robotfragment_title_btnlist"    android:orientation="horizontal"    android:layout_width="match_parent"    android:layout_height="98px"    android:layout_below="@+id/rl_robotfragment_title"    android:background="#eeffffff"    android:layout_marginTop="-2px"    android:clickable="false"    android:paddingTop="20px"    android:visibility="gone">    <RelativeLayout        android:layout_width="249px"        android:layout_height="match_parent">        <TextView            android:id="@+id/tv_robot_name"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="小薇1号"            android:singleLine="true"            android:ellipsize="end"            android:typeface="serif"            android:paddingLeft="20px"            android:paddingRight="20px"            android:drawableLeft="@mipmap/ic_player_robot_pressed"            android:textColor="@color/main_blue"            android:textSize="@dimen/fragment_title_textsize"            android:gravity="center"/>    </RelativeLayout>    <ImageView        android:layout_width="2px"        android:layout_height="60px"        android:src="@mipmap/ic_line"        android:layout_gravity="center_vertical"/>    <RelativeLayout        android:id="@+id/rl_seeMap"        android:layout_width="249px"        android:layout_height="match_parent">        <TextView            android:id="@+id/tv_see_map"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="@string/see_map_btn"            android:typeface="serif"            android:paddingLeft="30px"            android:paddingRight="30px"            android:drawableLeft="@mipmap/ic_map"            android:textColor="@color/grayText"            android:textSize="@dimen/fragment_title_textsize"            android:gravity="center"/>    </RelativeLayout>    <ImageView        android:layout_width="2px"        android:layout_height="60px"        android:src="@mipmap/ic_line"        android:layout_gravity="center_vertical"/>    <RelativeLayout        android:id="@+id/rl_manage_robot"        android:layout_width="249px"        android:layout_height="match_parent">        <TextView            android:id="@+id/tv_manage_robot"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:text="@string/manage_robot_btn"            android:paddingLeft="20px"            android:paddingRight="20px"            android:drawableLeft="@mipmap/ic_set"            android:typeface="serif"            android:textColor="@color/grayText"            android:textSize="@dimen/fragment_title_textsize"            android:gravity="center"/>    </RelativeLayout></LinearLayout>
