RelativeLayout xmlns:androidhttp://schemas.android.com/apk/res/androidxmlns:apphttp://schemas.android.com/apk/res-autoandroid:layout_widthmatch_parentandroid:layout_heightmatch_parentandroid:gravitycenterandroid:clipChildrenfalseandroid:layoutDirectionltr此处省略内部内容/RelativeLayoutdialog?.show()dialog?.apply {window?.setLayout(WindowManager.LayoutParams.MATCH_PARENT,WindowManager.LayoutParams.MATCH_PARENT)}
紧接着我们就可以使用动画了尤其是平移动画原来dialog是wrap_content的时候如何平移超过view就会消失。当dialog变成match_parent后就可以正常使用平移动画了。
思路根据位置计算平移的距离进行平移同时缩放 private fun setAnim(dialog: Dialog) {dialog.apply {val animView findViewByIdView(R.id.limited_layout)val height animView?.height//此处是在计算相应的距离等内容val retainHeight (screenHeight(context) - height!!) / 2 - DensityUtil.dp2px(ApplicationHelper.getInstance().context,84f) - getStatusBarHeight(context)val topHeight DensityUtil.dp2px(ApplicationHelper.getInstance().context,80f)val transHeight retainHeight - topHeight - DensityUtil.dp2px(ApplicationHelper.getInstance().context,28f).toFloat()val scaleAnimation if (retainHeight topHeight) {ScaleAnimation(1f, 0f,1f, 0f,Animation.RELATIVE_TO_SELF, 1f,Animation.RELATIVE_TO_SELF,((topHeight DensityUtil.dp2px(ApplicationHelper.getInstance().context,28f) - retainHeight) / height.toFloat()))} else {ScaleAnimation(1f, 0f,1f, 0f,Animation.RELATIVE_TO_SELF, 1f,Animation.RELATIVE_TO_SELF, 0f)}val translationAnimator if (retainHeight topHeight) {TranslateAnimation(0f,0f,0f,-transHeight)} else {null}translationAnimator?.let {val animationSet AnimationSet(true)scaleAnimation.duration 300animationSet.addAnimation(scaleAnimation)val alphaAnimation AlphaAnimation(1f, 0f)alphaAnimation.duration 300it.duration 300animationSet.addAnimation(it)animationSet.addAnimation(alphaAnimation)animView.startAnimation(animationSet)animationSet.setAnimationListener(object : Animation.AnimationListener {override fun onAnimationStart(animation: Animation?) {// 动画开始时的操作}override fun onAnimationEnd(animation: Animation?) {mLimitedDialog?.let { dismiss() }}override fun onAnimationRepeat(animation: Animation?) {// 动画重复时的操作}})} ?: run {val animationSet AnimationSet(true)scaleAnimation.duration 300animationSet.addAnimation(scaleAnimation)val alphaAnimation AlphaAnimation(1f, 0f)alphaAnimation.duration 300animationSet.addAnimation(alphaAnimation)animView.startAnimation(animationSet)animationSet.setAnimationListener(object : Animation.AnimationListener {override fun onAnimationStart(animation: Animation?) {// 动画开始时的操作}override fun onAnimationEnd(animation: Animation?) {mLimitedDialog?.let { dismiss() }}override fun onAnimationRepeat(animation: Animation?) {}})}}}
