Android进阶之路 - 仿京东地址选择器的详细使用

因为现在项目的地址选择器比较low，自己又比较懒，所以就找到了仿京东的地址选择器，观赏几篇博文之后，发现总是被半路卡死，很难一路走到底，所以找到了作者在github的地址，但是作者的功能简介又介绍的不是很详细，总会有一些小的知识点遗漏，到了最后只能非常无奈的查看了源代码，然后实现了自己的功能所需，一些小坑在下方列出，请君观赏。

小坑：

• 文中的展示有俩种方式，第一种是自定义添加到Linearlayout布局中，第二种是以弹框形式展示
• 因作者原始自定义BottomDialog的整体展示不太美观，而代码又限制只又读的权限，故重写了一份BottomDialog，设置了符合自己观赏的BottomDialog
• android中存在一些自定义的color，使用android.R.color.holo_orange_light进行引用

需掌握知识点：

• 接口回调
• RecyclerView、ListView
• 自定义Dialog

Effect ：

第一种

第二种

如
无法掌握本文知识，可使用以下这篇博文的地址选择器（使用更简单）

build (project) :

    }

        super(context, themeResId);
        init(context);
    }

    public BottomDialog(Context context, boolean cancelable, OnCancelListener cancelListener) {
        super(context, cancelable, cancelListener);
        init(context);
    }

    /**
     * 初始化
     *
     * @param context
     */
    private void init(Context context) {
        selector = new AddressSelector(context);
        setContentView(selector.getView());

        Window window = getWindow();
        WindowManager.LayoutParams params = window.getAttributes();
        params.width = WindowManager.LayoutParams.MATCH_PARENT;
        params.height = Dev.dp2px(context, 350);
        window.setAttributes(params);

        window.setGravity(Gravity.BOTTOM);
    }

    public void setOnAddressSelectedListener(OnAddressSelectedListener listener) {
        this.selector.setOnAddressSelectedListener(listener);
    }

    public static BottomDialog show(Context context) {
        return show(context, null);
    }

    public static BottomDialog show(Context context, OnAddressSelectedListener listener) {
        BottomDialog dialog = new BottomDialog(context, com.smarttop.library.R.style.bottom_dialog);
        dialog.selector.setOnAddressSelectedListener(listener);
        dialog.show();

        return dialog;
    }
    public void setDialogDismisListener(AddressSelector.OnDialogCloseListener listener){

    }
    /**
     *设置字体选中的颜色
     */
    public void setTextSelectedColor(int selectedColor){
        this.selector.setTextSelectedColor(selectedColor);
    }
    /**
     *设置字体没有选中的颜色
     */
    public void setTextUnSelectedColor(int unSelectedColor){
        this.selector.setTextUnSelectedColor(unSelectedColor);
    }
    /**
     * 设置字体的大小
     */
    public void setTextSize(float dp){
        this.selector.setTextSize(dp);
    }
    /**
     * 设置字体的背景
     */
    public void setBackgroundColor(int colorId){
        this.selector.setBackgroundColor(colorId);
    }
    /**
