创建XPopupWindow

/**

 * @author Xu
 */

class InputPopupWindow : XPopupWindow {
    private var btnLogin: Button? = null
    private var etPhone: TextInputEditText? = null

    constructor(ctx: Context) : super(ctx)

    constructor(ctx: Context, w: Int, h: Int) : super(ctx, w, h)

    /**
     * 设置popupwindow的layoutId
     */
    override fun getLayoutId(): Int {
        return R.layout.popup_input
    }

    /**
     * 设置layout的parentNodeId
     */
    override fun getLayoutParentNodeId(): Int {
        return R.id.input_parent
    }

    /**
     * 初始化界面
     */
    override fun initViews() {
        btnLogin = findViewById(R.id.btn_login)
        btnLogin?.setOnClickListener { dismiss() }
        etPhone = findViewById(R.id.et_mobile)
    }

    /**
     * 初始化数据
     */
    override fun initData() {
        // 设置弹窗背景透明度
        setShowingBackgroundAlpha(0.4f)
        // 弹窗弹出时自动获取输入框的焦点
        setAutoShowInput(etPhone, true)
    }

    /**
     * 为弹窗设置弹出动画，如果不想设置或是想通过xml方式设置，则设置返回值为-1
     */
    override fun startAnim(view: View): Animator? {
        var animatorX: ObjectAnimator = ObjectAnimator.ofFloat(view, "scaleX", 0f, 1f)
        var animatorY: ObjectAnimator = ObjectAnimator.ofFloat(view, "scaleY", 0f, 1f)
        var set = AnimatorSet()
        set.play(animatorX).with(animatorY)
        set.duration = 500
        return set
    }

    /**
     * 为弹窗设置退出动画，如果不想设置或是想通过xml方式设置，则设置返回值为-1
     */
    override fun exitAnim(view: View): Animator? {
        var animatorX: ObjectAnimator = ObjectAnimator.ofFloat(view, "scaleX", 1f, 0f)
        var animatorY: ObjectAnimator = ObjectAnimator.ofFloat(view, "scaleY", 1f, 0f)
        var set = AnimatorSet()
        set.play(animatorX).with(animatorY)
        set.duration = 700
        return set
    }

    /**
     * 通过xml方式设置动画，xml编写方法与原生popupwindow设置动画方法相同
     */
    override fun animStyle(): Int {
        return -1
    }

}

具体使用

private fun showInputPopup() {
    inputPopupWindow = InputPopupWindow(this, 1000, 600)
    // 可设置弹窗退出的监听器，在回调中执行相应操作
    inputPopupWindow?.setXPopupDismissListener(object : XPopupWindowDismissListener {
        override fun xPopupBeforeDismiss() {
        }

        override fun xPopupAfterDismiss() {
            Snackbar.make(findViewById(android.R.id.content), "登录成功！", Snackbar.LENGTH_LONG).show()
        }
    })
    inputPopupWindow?.showPopupFromScreenCenter(R.layout.activity_main)
}
