1. 界面布局
主界面布局四部分，由上到下依次是：标题栏，消息列表，底部菜弹出的子菜单，底部菜单或输入栏。
主界面基本框架main.xml代码如下：
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/main" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#E4E4E4" > <!-- 消息列表 --> <ListView android:id="@+id/lv" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_marginBottom="50dp" android:layout_marginTop="10dp" android:cacheColorHint="#00000000" android:divider="#00000000" android:dividerHeight="20dp" android:scrollbars="none" > </ListView> <!-- 点击底部菜单后弹出的子菜单 --> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="bottom" android:layout_marginBottom="50dp" android:orientation="horizontal" > <View android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="0.5" /> <LinearLayout android:id="@+id/pop_layout1" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_gravity="bottom" android:layout_weight="1" android:orientation="vertical" > </LinearLayout> <LinearLayout android:id="@+id/pop_layout2" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_gravity="bottom" android:layout_weight="1" android:orientation="vertical" > </LinearLayout> <LinearLayout android:id="@+id/pop_layout3" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_gravity="bottom" android:layout_weight="1" android:orientation="vertical" > </LinearLayout> </LinearLayout> <!-- 底部菜单 --> <LinearLayout android:id="@+id/bottom_layout" android:layout_width="fill_parent" android:layout_height="50dp" android:layout_gravity="bottom" android:background="#00ffffff" android:orientation="vertical" > <LinearLayout android:id="@+id/bottom_menu_layout1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#ffffff" android:orientation="vertical" > <View android:layout_width="fill_parent" android:layout_height="1px" android:background="#A6A6A6" /> <LinearLayout android:id="@+id/menu_layout" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:orientation="horizontal" > <ImageView android:id="@+id/keyboard" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_marginBottom="5dp" android:layout_marginLeft="3dp" android:layout_marginRight="3dp" android:layout_marginTop="5dp" android:layout_weight="0.5" android:background="@drawable/keyboard" /> <View android:layout_width="1px" android:layout_height="fill_parent" android:background="#A6A6A6" /> <RelativeLayout android:id="@+id/btn1" android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="1" android:background="@drawable/btn_selector" > <RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_margin="5dp" > <TextView android:id="@+id/text1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_centerInParent="true" android:gravity="center" android:text="用户绑定" android:textColor="#000000" android:textSize="16sp" /> <ImageView android:layout_width="10dp" android:layout_height="10dp" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:src="@drawable/more_icon" android:visibility="invisible" /> </RelativeLayout> </RelativeLayout> <View android:layout_width="1px" android:layout_height="fill_parent" android:background="#A6A6A6" /> <RelativeLayout android:id="@+id/btn2" android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="1" android:background="@drawable/btn_selector" > <RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_margin="5dp" > <TextView android:id="@+id/text2" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_centerInParent="true" android:gravity="center" android:text="扫描签到" android:textColor="#000000" android:textSize="16sp" /> <ImageView android:layout_width="10dp" android:layout_height="10dp" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:src="@drawable/more_icon" android:visibility="invisible" /> </RelativeLayout> </RelativeLayout> <View android:layout_width="1px" android:layout_height="fill_parent" android:background="#A6A6A6" /> <RelativeLayout android:id="@+id/btn3" android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="1" android:background="@drawable/btn_selector" > <RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_margin="5dp" > <TextView android:id="@+id/text3" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_centerInParent="true" android:gravity="center" android:text="更多" android:textColor="#000000" android:textSize="16sp" /> <ImageView android:layout_width="10dp" android:layout_height="10dp" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:src="@drawable/more_icon" android:visibility="visible" /> </RelativeLayout> </RelativeLayout> </LinearLayout> </LinearLayout> </LinearLayout> </FrameLayout>
标题栏title_bar.xml布局如下：
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal" > <!-- 返回 --> <ImageView android:id="@+id/title_bar_back_btn" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_centerVertical="true" android:layout_marginLeft="10dip" android:src="@drawable/back" /> <!-- 服务号名称 --> <TextView android:id="@+id/my_setting_title_tv" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:text="腾讯招聘面试服务" android:textColor="#ffffff" android:textSize="20sp" /> <!-- 服务号 --> <ImageView android:id="@+id/title_bar_my" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:layout_marginRight="10dip" android:src="@drawable/my" /> </RelativeLayout>
完成title_bar布局后，再在values\styles.xml添加自定义标题栏主题
<!-- 自定义标题栏背景颜色 --> <style name="CustomWindowTitleBackground"> <item name="android:background">#32394A</item> </style> <!-- 自定义标题栏主题 --> <style name="myTheme" parent="android:Theme"> <item name="android:windowTitleSize">45dp</item> <item name="android:windowTitleBackgroundStyle">@style/CustomWindowTitleBackground</item> </style>
消息列表的服务端消息item布局item_left.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <RelativeLayout android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="4" > <ImageView android:id="@+id/server_image" android:layout_width="40dp" android:layout_height="40dp" android:layout_marginLeft="2dp" android:background="@drawable/qq"/> <TextView android:id="@+id/server_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="2dp" android:layout_toRightOf="@id/server_image" android:background="@drawable/text_bg_left1" android:gravity="center_vertical|left" android:textSize="16sp" android:textColor="#000000"/> </RelativeLayout> <View android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="1" /> </LinearLayout>
消息列表的用户消息item布局item_right.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <View android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="1" /> <RelativeLayout android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="4" > <ImageView android:id="@+id/user_image" android:layout_width="40dp" android:layout_height="40dp" android:layout_alignParentRight="true" android:layout_marginRight="2dp" android:background="@drawable/qq" /> <TextView android:id="@+id/user_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginRight="1dp" android:layout_toLeftOf="@id/user_image" android:background="@drawable/text_bg_right1" android:gravity="center_vertical|right" android:textColor="#000000" android:textSize="16sp" /> </RelativeLayout> </LinearLayout>
弹出的子菜单布局child_menu.xml如下：
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/child_layout" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="#FFFFFF" android:gravity="bottom" android:orientation="vertical" > <RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content" > <Button android:id="@+id/test1" android:layout_width="wrap_content" android:layout_height="45dp" android:background="@drawable/btn_selector" android:paddingLeft="10dp" android:paddingRight="10dp" android:text="进度查询" android:textColor="#000000" android:textSize="16sp" /> <View android:layout_width="wrap_content" android:layout_height="1px" android:layout_alignLeft="@id/test1" android:layout_alignRight="@id/test1" android:layout_below="@id/test1" android:background="#E4E4E4" /> </RelativeLayout> <RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content" > <Button android:id="@+id/test1" android:layout_width="wrap_content" android:layout_height="45dp" android:background="@drawable/btn_selector" android:paddingLeft="10dp" android:paddingRight="10dp" android:text="使用帮助" android:textColor="#000000" android:textSize="16sp" /> <View android:layout_width="wrap_content" android:layout_height="1px" android:layout_alignLeft="@id/test1" android:layout_alignRight="@id/test1" android:layout_below="@id/test1" android:background="#E4E4E4" /> </RelativeLayout> <RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content" > <Button android:id="@+id/test1" android:layout_width="wrap_content" android:layout_height="45dp" android:background="@drawable/btn_selector" android:paddingLeft="10dp" android:paddingRight="10dp" android:text="联系我们" android:textColor="#000000" android:textSize="16sp" /> <View android:layout_width="wrap_content" android:layout_height="1px" android:layout_alignLeft="@id/test1" android:layout_alignRight="@id/test1" android:layout_below="@id/test1" android:background="#E4E4E4" /> </RelativeLayout> </LinearLayout>
由底部菜单切换到输入框，输入框bottom_menu_layout2.xml布局如下：
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <LinearLayout android:id="@+id/bottom_menu_layout2" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#ffffff" android:orientation="vertical" > <View android:layout_width="fill_parent" android:layout_height="1px" android:background="#A6A6A6" /> <LinearLayout android:id="@+id/menu_layout" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:orientation="horizontal" > <!-- 左侧切换菜单按钮 --> <ImageView android:id="@+id/menu" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_marginBottom="5dp" android:layout_marginLeft="3dp" android:layout_marginRight="3dp" android:layout_marginTop="5dp" android:layout_weight="0.5" android:background="@drawable/menu" /> <View android:layout_width="1px" android:layout_height="fill_parent" android:background="#A6A6A6" /> <RelativeLayout android:id="@+id/btn1" android:layout_width="0dp" android:layout_height="fill_parent" android:layout_margin="5dp" android:layout_weight="3" android:background="#ffffff" > <ImageView android:id="@+id/voice" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_centerInParent="true" android:layout_marginLeft="5dp" android:src="@drawable/voice" /> <!-- 右侧“+”按钮或发送按钮 --> <Button android:id="@+id/add" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_centerInParent="true" android:layout_marginRight="1dp" android:background="@drawable/add" android:paddingBottom="5dp" android:paddingLeft="8dp" android:paddingRight="8dp" android:paddingTop="5dp" android:text="" android:textColor="#ffffff" android:textSize="14sp" /> <!-- 输入 --> <RelativeLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_centerInParent="true" android:layout_marginLeft="5dp" android:layout_marginRight="5dp" android:layout_toLeftOf="@id/add" android:layout_toRightOf="@id/voice" > <EditText android:id="@+id/input_text" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_centerVertical="true" android:background="#00000000" android:gravity="bottom" android:paddingLeft="2dp" android:paddingRight="2dp" android:text="" android:textColor="#000000" android:textSize="16sp" /> <View android:layout_width="fill_parent" android:layout_height="1px" android:layout_below="@id/input_text" android:layout_marginTop="10dp" android:background="#A6A6A6" /> </RelativeLayout> </RelativeLayout> </LinearLayout> </LinearLayout> </LinearLayout>
