Android 实现仿淘宝地址多级选择器,android,java,开发语言

仿淘宝的选择完城市出来的选择省市区之类的，这个支持自定义层级，多少层都可以使用，接下来是代码:

BottomPopUtils.class，我写了一个工具类，方便全局调用

public class BottomPopUtils {

    public static ProjectTitleAdapter titleAdapter;
    public static ProjectAdapter adapter1;
    public static PopupWindow popupWindow;
    public static View contentView;
    public static StringBuilder result;

    public static void showPopWindow(List<ProjectTitleItemBean> listTop, List<ProjectItemBean> listContent, Activity context, Finish finish) {
        result = new StringBuilder();
        Map<Integer, List<ProjectItemBean>> nowMap = new HashMap<>();

        //加载弹出框的布局
        contentView = LayoutInflater.from(context).inflate(
                R.layout.popupwindow, null);
        // 设置按钮的点击事件
        ImageView ivFinish = contentView.findViewById(R.id.iv_finish);

        RecyclerView rl = contentView.findViewById(R.id.rl);
        RecyclerView rlTitle = contentView.findViewById(R.id.rl_title);

        //这个为了取出第一级的数据
        List<ProjectItemBean> item = new ArrayList<>();
        for (int i = 0; i < listContent.size(); i++) {
            if (listContent.get(i).getLevel() == 0) {
                item.add(listContent.get(i));
            }
        }
        List<ProjectItemBean> firstMap = new ArrayList<>();

        for (int i = 0; i < item.size(); i++) {
            ProjectItemBean itemBean1 = item.get(i);
            firstMap.add(BeanCloneUtil.cloneTo(itemBean1));
        }

        nowMap.put(0, firstMap);

        titleAdapter = new ProjectTitleAdapter(context, listTop, (itemBean, position) -> {
            //每次用户点击顶部集合的时候，移除掉点击下标后的所有数据
            int size = listTop.size();
            for (int i = position + 1; i < size; i++) {
                listTop.remove(position + 1);
            }

            titleAdapter.notifyDataSetChanged();


            Iterator<Map.Entry<Integer, List<ProjectItemBean>>> iterator = nowMap.entrySet().iterator();
            while (iterator.hasNext()) {
                Map.Entry<Integer, List<ProjectItemBean>> entry = iterator.next();
                Integer key = entry.getKey();
                if (key > position) {
                    iterator.remove();
                }
            }

            List<ProjectItemBean> items = new ArrayList<>();
            List<ProjectItemBean> listNow = nowMap.get(position);
            if (listNow != null) {

                    items.add(listNow.get(i));
                }
            }

            item.clear();
            item.addAll(items);

            titleAdapter.notifyDataSetChanged();


            //如果当前选择的数据是否有子集合
            if (itemBean.getChildList() != null && itemBean.getChildList().size() > 0) {
                item.clear();

                    item.addAll(new ArrayList<>());
                } else {
                    item.addAll(itemBean.getChildList());
                }

                ProjectTitleItemBean bean = new ProjectTitleItemBean();

            }
        });
        rl.setLayoutManager(new LinearLayoutManager(context));
        rl.setAdapter(adapter1);

        ivFinish.setOnClickListener(v -> {

BeanCloneUtil 用来复制bean类，保证数据的修改不会影响其他map

public abstract class BeanCloneUtil {
    @SuppressWarnings("unchecked")
    public static <T> T cloneTo(T src) throws RuntimeException {
        ByteArrayOutputStream memoryBuffer = new ByteArrayOutputStream();
        ObjectOutputStream out = null;
        ObjectInputStream in = null;
        T dist = null;
        try {
            out = new ObjectOutputStream(memoryBuffer);
            out.writeObject(src);
            out.flush();
            in = new ObjectInputStream(new ByteArrayInputStream(memoryBuffer.toByteArray()));
            dist = (T) in.readObject();
        } catch (Exception e) {
            throw new RuntimeException(e);
        } finally {
            if (out != null)
                try {
                    out.close();
                    out = null;
                } catch (IOException e) {
                    throw new RuntimeException(e);
                }
            if (in != null)
                try {
                    in.close();
                    in = null;
                } catch (IOException e) {
                    throw new RuntimeException(e);
                }
        }
        return dist;
    }
}

ProjectTitleAdapter  顶部的列表适配器

public class ProjectTitleAdapter extends RecyclerView.Adapter<ProjectTitleAdapter.ViewHolder> {
    private Context context;
    private List<ProjectTitleItemBean> list;
    private ProjectTitleItemClick itemClick;

    public ProjectTitleAdapter(Context context, List<ProjectTitleItemBean> list,

    public ProjectTitleAdapter(Context context, List<ProjectTitleItemBean> list) {
        this.context = context;
        this.list = list;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(context).inflate(R.layout.pop_time_line, parent, false);
        ViewHolder holder = new ViewHolder(view);
        return holder;
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        ProjectTitleItemBean item = list.get(position);

        if (item.isChoose()) {

        holder.tvName.setText(item.getName());

        holder.tvName.setOnClickListener(view -> {

        });

    }

    @Override
    public int getItemCount() {

    }

    class ViewHolder extends RecyclerView.ViewHolder {

        }
    }
}

ProjectAdapter 底部的列表适配器

public class ProjectAdapter extends RecyclerView.Adapter<ProjectAdapter.ViewHolder> {
    private Context context;
    private List<ProjectItemBean> list;
    private ProjectItemClick itemClick;

    public ProjectAdapter(Context context, List<ProjectItemBean> list,

    }

    @NonNull
    @Override

        ViewHolder holder = new ViewHolder(view);
        return holder;
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        ProjectItemBean item = list.get(position);

        if (item.isChoose()) {
            holder.tvName.setTypeface(null, Typeface.BOLD);
            holder.ivSelect.setVisibility(View.VISIBLE);
        } else {
            holder.tvName.setTypeface(null, Typeface.NORMAL);
            holder.ivSelect.setVisibility(View.INVISIBLE);
        }

        holder.tvName.setText(item.getName());

        holder.tvName.setOnClickListener(view -> {
            itemClick.itemListener(item);
        });

    }

    @Override
    public int getItemCount() {
        return list.size();
    }

    class ViewHolder extends RecyclerView.ViewHolder {

        private final TextView tvName;

            ivSelect = itemView.findViewById(R.id.iv_select);
        }
    }
}

ProjectTitleItemBean 顶部的实体类

public class ProjectTitleItemBean {
    private String name;
    private String id;
    private String code;
    private boolean isChoose;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getCode() {

    public void setCode(String code) {
        this.code = code;
    }

    public boolean isChoose() {
        return isChoose;
    }

    public void setChoose(boolean choose) {
        isChoose = choose;
    }
}

ProjectItemBean 底部实体类

public class ProjectItemBean implements Serializable {
    private String id;
    private String name;
    private String code;
    private boolean isChoose;
    private int level;
    private List<ProjectItemBean> childList = new ArrayList<>();
    private ProjectItemBean parent;

    public String getId() {

    public void setCode(String code) {
        this.code = code;
    }

    public boolean isChoose() {

    }

    public void setParent(ProjectItemBean parent) {
        this.parent = parent;
    }
}

ProjectTitleItemClick 顶部条目点击

public interface ProjectTitleItemClick {
    void itemListener(ProjectTitleItemBean itemBean,int position);
}

ProjectItemClick 底部条目点击

public interface ProjectItemClick {
    void itemListener(ProjectItemBean itemBean);
}

MainActivity 主页面的代码,顶部的集合默认给一条就行，后续的顶部集合自增或自减都是在适配器里完成的

public class MainActivity extends AppCompatActivity {

    private TextView tvContent;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button bottom = findViewById(R.id.btn_bottom);
        tvContent = findViewById(R.id.tvContent);
        bottom.setOnClickListener(v -> initPop());
    }

    private void initPop() {
        List<ProjectTitleItemBean> listTop = new ArrayList<>();
        ProjectTitleItemBean bean = new ProjectTitleItemBean();

        ProjectItemBean bean111 = new ProjectItemBean();
        bean111.setName("第1-1-1页");
        bean111.setChoose(false);
        bean111.setParent(bean1);
        bean111.setChildList(null);
        bean111.setLevel(2);
        listChild11.add(bean111);

        ProjectItemBean bean112 = new ProjectItemBean();

        bean12.setName("第1-2页");
        bean12.setChoose(false);
        bean12.setParent(bean1);
        bean12.setChildList(null);
        bean12.setLevel(1);
        listChild1.add(bean12);
        bean1.setChildList(listChild1);
        listChild.add(bean1);

        ProjectItemBean bean2 = new ProjectItemBean();
        bean2.setName("第二页");
        bean2.setChoose(false);
        bean2.setParent(null);
        bean2.setLevel(0);

        List<ProjectItemBean> listChild2 = new ArrayList<>();
        ProjectItemBean bean21 = new ProjectItemBean();
        bean21.setName("第2-1页");
        bean21.setChoose(false);
        bean21.setParent(bean1);
        bean21.setChildList(null);
        bean21.setLevel(1);
        listChild2.add(bean21);
        ProjectItemBean bean22 = new ProjectItemBean();
        bean22.setName("第2-2页");
        bean22.setChoose(false);
        bean22.setParent(bean1);
        bean22.setChildList(null);
        bean22.setLevel(1);
        listChild2.add(bean22);
        bean2.setChildList(listChild2);
        listChild.add(bean2);


        BottomPopUtils.showPopWindow(listTop, listChild, MainActivity.this,result -> {
            tvContent.setText(result);
        });
    }
}

接下来是布局：

popupwindow 我的时间线设计的有点问题，有点偏差对不准，欢迎各位大佬提点修改方法

<?xml version="1.0" encoding="utf-8"?>

            app:layout_constraintTop_toBottomOf="@id/view2" />

    </androidx.constraintlayout.widget.ConstraintLayout>
</LinearLayout>

接下来是drawable文件：

circle_no.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <corners android:radius="100dp"/>

    <solid android:color="#FFFFFF" />

    <stroke
        android:width="1dp"
        android:color="@color/cardview_dark_background" />
</shape>

circle_yes.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <corners android:radius="100dp"/>
    <solid android:color="@color/cardview_dark_background"/>
</shape>

popwindow_radius_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <corners android:radius="14dp"/>
    <solid android:color="#FFFFFF" />
</shape>

接下来是anim，需要在res下创建anim文件夹，主要用作popwindow的弹出动画

pophidden_anim.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="300"
        android:fromYDelta="0"
        android:toYDelta="50%p" />
    <alpha
        android:duration="300"
        android:fromAlpha="1.0"
        android:toAlpha="0.0" />
</set>

popshow_anim.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <alpha
        android:duration="300"
        android:fromAlpha="0.0"
        android:toAlpha="1.0" />

    <translate
        android:duration="300"
        android:fromYDelta="100%p"
        android:toYDelta="0" />
</set>

styles里面的代码

<resources>
    <style name="ipopwindow_anim_style">
        <item name="android:windowEnterAnimation">@anim/popshow_anim</item>
        <!-- 指定显示的动画xml -->
        <item name="android:windowExitAnimation">@anim/pophidden_anim</item>
        <!-- 指定消失的动画xml -->
    </style>
</resources>

还有两张图片没上传，是底部列表后面的对勾，还有popwindow的关闭按钮,这个你们自己找图片替换掉就行；文章来源地址https://www.toymoban.com/news/detail-605861.html
