问题描述

点击edittext，弹出软键盘，dialog略微上移，edittext和下面的按钮还是被遮挡，上移的部分被切割

解决方案

设置dialog的inputMode，取消软键盘弹出自动上移

监听软键盘弹出事件，动态设置dialog的paddingBottom

override fun init() {

dialog?.window?.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_NOTHING)

globalListener = KeyboardUtils.registerSoftInputChangedListener(activity, object : KeyboardUtils.OnSoftInputChangedListener {

override fun onSoftInputChanged(height: Int) {

val activityPos = intArrayOf(0, 0)

val dialogPos = intArrayOf(0, 0)

activity.window.decorView.getLocationOnScreen(activityPos)

getLocationOnScreen(dialogPos)

val gap = activity.window.decorView.bottom + activityPos[1] - (bottom + dialogPos[1])

if (height > 10 && gap < height) {

dialog?.window?.decorView?.setPadding(0, 0, 0, height - gap + 50)

} else {

dialog?.window?.decorView?.setPadding(0, 0, 0, 0)

}

}

})

}

override fun onDestroy() {

super.onDestroy()

if (globalListener != null) {

KeyboardUtils.unregisterSoftInputChangedListener(activity, globalListener!!)

}

}

fun registerSoftInputChangedListener(activity: Activity,

listener: OnSoftInputChangedListener?)

: ViewTreeObserver.OnGlobalLayoutListener {

val contentView = activity.findViewById(android.R.id.content)

sContentViewInvisibleHeightPre = getContentViewInvisibleHeight(activity)

val globalListener = ViewTreeObserver.OnGlobalLayoutListener {

if (listener != null) {

val height = getContentViewInvisibleHeight(activity)

if (sContentViewInvisibleHeightPre != height) {

listener.onSoftInputChanged(height)

sContentViewInvisibleHeightPre = height

}

}

}

contentView.viewTreeObserver.addOnGlobalLayoutListener(globalListener)

return globalListener

}

fun unregisterSoftInputChangedListener(activity: Activity,

listener: ViewTreeObserver.OnGlobalLayoutListener) {

val contentView = activity.findViewById(android.R.id.content)

contentView.viewTreeObserver.removeOnGlobalLayoutListener(listener)

}

private fun getContentViewInvisibleHeight(activity: Activity): Int {

val contentView = activity.findViewById(android.R.id.content)

val outRect = Rect()

contentView.getWindowVisibleDisplayFrame(outRect)

return contentView.bottom - outRect.bottom

}

总结

dialog销毁一定要移除global监听，否则回调里面拿到的window是上一次的
