现在使用较多的类似美团、外卖等APP的城市选择界面,一行代码搞定,就是这么简单粗暴!!!
Tips:(旧版本1.x)会报高德定位jar包冲突,推荐使用2.x版本。
下载demo.apk体验.
1: 项目根目录的build.gradle添加如下配置:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
2: app添加依赖:
dependencies {
implementation 'com.github.zaaach:CityPicker:x.y.z'
}
CityPicker
基于DialogFragment
实现,已提供定位接口,需要APP自身实现定位。
在manifest.xml
中给使用CityPicker
的activity
添加主题android:theme="@style/DefaultCityPickerTheme"
<activity android:name=".MainActivity" android:theme="@style/DefaultCityPickerTheme">
......
</activity>
注意:热门城市使用HotCity
,定位城市使用LocatedCity
List<HotCity> hotCities = new ArrayList<>();
hotCities.add(new HotCity("北京", "北京", "101010100")); //code为城市代码
hotCities.add(new HotCity("上海", "上海", "101020100"));
hotCities.add(new HotCity("广州", "广东", "101280101"));
hotCities.add(new HotCity("深圳", "广东", "101280601"));
hotCities.add(new HotCity("杭州", "浙江", "101210101"));
......
CityPicker.from(activity) //activity或者fragment
.enableAnimation(true) //启用动画效果,默认无
.setAnimationStyle(anim) //自定义动画
.setLocatedCity(new LocatedCity("杭州", "浙江", "101210101"))) //APP自身已定位的城市,传null会自动定位(默认)
.setHotCities(hotCities) //指定热门城市
.setOnPickListener(new OnPickListener() {
@Override
public void onPick(int position, City data) {
Toast.makeText(getApplicationContext(), data.getName(), Toast.LENGTH_SHORT).show();
}
@Override
public void onCancel(){
Toast.makeText(getApplicationContext(), "取消选择", Toast.LENGTH_SHORT).show();
}
@Override
public void onLocate() {
//定位接口,需要APP自身实现,这里模拟一下定位
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
//定位完成之后更新数据
CityPicker.getInstance()
.locateComplete(new LocatedCity("深圳", "广东", "101280601"), LocateState.SUCCESS);
}
}, 3000);
}
})
.show();
在style.xml
中自定义主题并且继承DefaultCityPickerTheme
,别忘了在manifest.xml
设置给activity
。
<style name="CustomTheme" parent="DefaultCityPickerTheme">
<item name="cpCancelTextColor">@color/color_green</item>
<item name="cpSearchCursorDrawable">@color/color_green</item>
<item name="cpIndexBarNormalTextColor">@color/color_green</item>
<item name="cpIndexBarSelectedTextColor">@color/color_green</item>
<item name="cpSectionHeight">@dimen/custom_section_height</item>
<item name="cpOverlayBackground">@color/color_green</item>
......
</style>
CityPicker
中自定义的所有属性如下,有些属性值必须是引用类型refrence
,使用时注意。
<resources>
<attr name="cpCancelTextSize" format="dimension|reference" />
<attr name="cpCancelTextColor" format="color|reference" />
<attr name="cpClearTextIcon" format="reference" />
<attr name="cpSearchTextSize" format="dimension|reference" />

<attr name="cpEmptyTextSize" format="dimension|reference"/>
<attr name="cpEmptyTextColor" format="color|reference"/>

<attr name="cpSectionBackground" format="reference" />

<attr name="cpIndexBarNormalTextColor" format="reference" />
<attr name="cpIndexBarSelectedTextColor" format="reference" />
<!--特写布局-->

<attr name="cpOverlayHeight" format="dimension|reference"/>
<attr name="cpOverlayTextSize" format="dimension|reference"/>
<attr name="cpOverlayTextColor" format="color|reference"/>
<attr name="cpOverlayBackground" format="color|reference"/>
</resources>
