CityPicker

Platform API

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！！！

主要功能：

Download

1.先在项目根目录的 build.gradle 的 repositories 添加:

allprojects {
     repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

2.然后在dependencies添加:

dependencies {
  ...
  implementation 'com.github.xuexiangjys:citypicker:1.0.1'
  implementation 'com.android.support:appcompat-v7:27.1.1'
  implementation 'com.android.support:recyclerview-v7:27.1.1'
  implementation 'com.android.support:design:27.1.1'
}

Usage

CityPicker 基于DialogFragment 实现，已提供定位接口，需要APP自身实现定位。

基本使用：

Step1:

在manifest.xml中给使用CityPicker 的activity添加主题android:theme="@style/CityPickerTheme"

<activity android:name=".MainActivity" android:theme="@style/CityPickerTheme">
  ......
</activity>

Step2:

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(MainActivity.this)
    .enableAnimation(enable)
    .setAnimationStyle(anim)
    .setLocatedCity(null)
    .setHotCities(hotCities)
    .setOnPickListener(new OnPickListener() {
        @Override
        public void onPick(int position, City data) {
            currentTV.setText(String.format("当前城市：%s，%s", data.getName(), data.getCode()));
            Toast.makeText(
                    getApplicationContext(),
                    String.format("点击的数据：%s，%s", data.getName(), data.getCode()),
                    Toast.LENGTH_SHORT)
                    .show();
        }

        @Override
        public void onCancel() {
            Toast.makeText(getApplicationContext(), "取消选择", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onLocate(final OnLocationListener locationListener) {
            //开始定位，这里模拟一下定位
            new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    locationListener.onLocationChanged(new LocatedCity("深圳", "广东", "101280601"), LocateState.SUCCESS);
                }
            }, 3000);
        }
    })
    .show();

关于自定义主题：

在style.xml 中自定义主题并且继承CityPickerTheme ，别忘了在manifest.xml 设置给activity。

<style name="CustomTheme" parent="CityPickerTheme">
        <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reference，使用时注意。

<resources>
    <!--取消按钮的样式-->
    <attr name="cpCancelTextSize" format="dimension|reference" />
    <attr name="cpCancelTextColor" format="color|reference" />

    <!--搜索样式-->
    <attr name="cpClearTextIcon" format="reference" />
    <attr name="cpSearchTextSize" format="dimension|reference" />

    <attr name="cpSearchHintText" format="string|reference" />
    <attr name="cpSearchHintTextColor" format="color|reference" />
    <attr name="cpSearchCursorDrawable" format="reference" />

    <!--城市列表样式-->
    <attr name="cpListItemTextSize" format="dimension|reference" />
    <attr name="cpListItemTextColor" format="color|reference" />

    <attr name="cpIndexBarTextSize" format="reference" />
    <attr name="cpIndexBarNormalTextColor" format="reference" />
    <attr name="cpIndexBarSelectedTextColor" format="reference" />

    <!--悬浮字母序提示-->
    <attr name="cpOverlayWidth" format="dimension|reference"/>
    <attr name="cpOverlayHeight" format="dimension|reference"/>
    <attr name="cpOverlayTextSize" format="dimension|reference"/>
