特性

• 簡單快速地建立一個自定義彈窗
• 以一種相對便捷的方式設置彈窗位置
• 更加自由地調整你的彈窗動畫

開始

使用Gradle：

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

dependencies {
    implementation 'com.github.XuDeveloper:XPopupWindow:1.0.1'
}

使用

以建立一個登陸彈窗爲例：

界面編寫

（略，含有一個帳號輸入框，一個密碼輸入框以及登陸按鈕，github有demo）

建立XPopupWindow

/** * Created by Xu on 2018/6/17. * @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)

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

    /** * 設置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)
    }

    /** * 初始化數據 */
    override fun initData() {
        // 設置彈窗背景透明度
        setShowingBackgroundAlpha(0.4f)
        // 彈窗彈出時自動獲取輸入框的焦點
        setAutoShowInput(etPhone, true)
    }

    /** * 爲彈窗設置彈出動畫，若是不想設置或是想經過xml方式設置，則設置返回值爲-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
    }

    /** * 爲彈窗設置退出動畫，若是不想設置或是想經過xml方式設置，則設置返回值爲-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
    }

    /** * 經過xml方式設置動畫，xml編寫方法與原生popupwindow設置動畫方法相同 */
    override fun animStyle(): Int {
        return -1
    }

}

具體使用

private fun showInputPopup() {
    inputPopupWindow = InputPopupWindow(this, 1000, 600)
    // 可設置彈窗退出的監聽器，在回調中執行相應操做
    inputPopupWindow?.setXPopupDismissListener(object : XPopupWindowDismissListener {
        override fun xPopupBeforeDismiss() {
        }

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