android 城市列表

项目中采用了三种样式城市选择(无语....),第一种是:

第二种是:

第三种是:

我用两个水平的ListView实现的(可以用ListFragment,也可以两个Fragment),布局代码:

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
        <ListView
            android:id="@+id/province"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:cacheColorHint="@android:color/transparent"
            android:divider="@color/line_xx"
            android:dividerHeight="1px"
            android:layout_weight="2"
            android:choiceMode="singleChoice"
            android:scrollbars="none"/>
        <ListView
            android:id="@+id/city"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:cacheColorHint="@android:color/transparent"
            android:divider="@color/line_xx"
            android:dividerHeight="1px"
            android:layout_weight="1"
            android:scrollbars="none"/>
    </LinearLayout>
ListView需要单选模式
android:choiceMode="singleChoice"

Activity代码:

    @AfterViews
    @Override
    protected void afterInstanceView() {
        //构造当前地区
        Area currentArea=new Area();
        currentArea.setName("当前地区");
        ArrayList<Area.CityBean> currentCity=new ArrayList<Area.CityBean>();
        Area.CityBean cityBean=new Area.CityBean();
        String currentCityStr=getIntent().getStringExtra("currentCity");
        cityBean.setName(currentCityStr);
        currentCity.add(cityBean);
        currentArea.setCity(currentCity);
        mAreaList.add(currentArea);
        mAreaList.addAll(ParseJson.getArea(getApplicationContext()));
        mProvinceAdapter=new ProvinceAdapter();
        mProvince.setAdapter(mProvinceAdapter);
        mProvince.setOnItemClickListener(this);
        new Handler().postDelayed(() -> {
            //选中第一项
            mProvince.performItemClick(mProvince.getChildAt(0),0,mProvince.getItemIdAtPosition(0));
        },700);

    }

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        mIsClick=true;
        mIndex=position;
        for (int i=0;i<mProvince.getChildCount();i++){
            if (mIndex!=i){
                View view1=mProvince.getChildAt(i);
                view1.findViewById(R.id.current).setVisibility(View.GONE);
            }
        }
        view.findViewById(R.id.current).setVisibility(View.VISIBLE);
        if (mCityAdapter==null){
            mCityAdapter=new CommonAdapter<Area.CityBean>(mAreaList.get(0).getCity(),R.layout.adapter_city) {
                @Override
                public void onBindViewHolder(ViewHolder holder, int index) {
                    if (mIndex==0){
                        holder.findViewById(R.id.current).setVisibility(View.VISIBLE);
                    }else {
                        holder.findViewById(R.id.current).setVisibility(View.GONE);
                    }
                    holder.setText(R.id.city,mAreaList.get(mIndex).getCity().get(index).getName());
                }
            };
            mCity.setAdapter(mCityAdapter);
        }else {
            mCityAdapter.update(mAreaList.get(mIndex).getCity());
        }
    }


ListView子View布局背景选择器代码:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:state_pressed="true" android:drawable="@color/white"/>
        <item android:state_selected="true" android:drawable="@color/white"/>
        <item android:state_activated="true" android:drawable="@color/white"/>
        <item android:drawable="@color/list_line"/>
</selector>
一开始我没有采用遍历的方式(上面红色那段代码),而是子View中的ImageView 用选择器,代码如下:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@mipmap/current"/>
    <item android:state_selected="true" android:drawable="@mipmap/current"/>
    <item android:state_activated="true" android:drawable="@mipmap/current"/>
</selector>
但是发现两个bug,一是:ListView选中ItemClick其他的子View中的 没有GONE。二是上、下拉ListView选中的Item从可见-》不可见-》可见, 就不可见了。最后放弃了这种方式,采用遍历的方式。
