在res/anim下

activity_main.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center_horizontal" tools:context="com.loaderman.addressdialogdemo.MainActivity"> <Button android:onClick="set" android:id="@+id/btn_set" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="风格样式设置"/> </LinearLayout>
dialog_address.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:text="选择归属地样式" android:id="@+id/textView2" android:background="#cccccc" android:padding="8dp" android:textColor="@color/black" android:textSize="18sp" android:layout_gravity="center_horizontal"/> <ListView android:layout_width="match_parent" android:layout_height="200dp" android:id="@+id/lv_list"/> </LinearLayout>
item_address.xml
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:padding="8dp"> <ImageView android:id="@+id/iv_icon" android:layout_width="60dp" android:layout_height="30dp" android:layout_centerVertical="true" android:src="@drawable/shape_address_normal"/> <TextView android:id="@+id/tv_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_marginLeft="5dp" android:layout_toRightOf="@+id/iv_icon" android:text="半透明" android:textColor="@color/black" android:textSize="18sp" /> <ImageView android:id="@+id/iv_select" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:src="@drawable/ic_selected" /> </RelativeLayout>
在res/drawable下
shape_address_blue.xml shape_address_gray.xml shape_address_green.xml shape_normal_blue.xml shape_address_orange.xml只需要把下面代码需要以下color即可
<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> <!--颜色--> <solid android:color="@color/global_blue"/> <!--给矩形加圆角--> <corners android:radius="6dp"/> </shape>
在res/values/colors.xml添加需求颜色值即可如
<?xml version="1.0" encoding="utf-8"?> <resources> <color name="colorPrimary">#3F51B5</color> <color name="colorPrimaryDark">#303F9F</color> <color name="colorAccent">#FF4081</color> <color name="red">#F00</color> <color name="black">#000</color> <color name="gray">#a000</color> <color name="global_blue">#459FD7</color> <color name="white">#fff</color> <color name="light_gray">#cccccc</color> <color name="light_green">#00ffa1</color> </resources>
在res/values/style.xml中在resources节点下添加style
<!--归属地弹窗样式--> <style name="AddressDialogStyle" parent="Theme.AppCompat.Dialog"> <!--去掉标题栏--> <item name="android:windowNoTitle">true</item> <!--去掉背景--> <item name="android:windowBackground">@color/white</item> <!--设置进入退出动画--> <item name="android:windowAnimationStyle">@style/AddressAnimStyle</item> </style> <!--归属地弹窗动画--> <style name="AddressAnimStyle"> <item name="android:windowEnterAnimation">@anim/anim_dialog_enter</item> <item name="android:windowExitAnimation">@anim/anim_dialog_exit</item> </style>
