首先，我将向您展示 BottomSheetDialogFragment 类。
class BottomSheetReportFragment(var mContext: Context, var postId: String, var commentId: String?, var replyId: String?) : BottomSheetDialogFragment() {
private lateinit var mView: View
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setStyle(DialogFragment.STYLE_NORMAL, R.style.AppBottomSheetDialogTheme)
}
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
mView = inflater.inflate(R.layout.bottom_sheet_report, container, false)
return mView
}
override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
val dialog = super.onCreateDialog(savedInstanceState)
dialog.setOnShowListener { dialogInterface ->
val bottomSheetDialog = dialogInterface as BottomSheetDialog
setupRatio(bottomSheetDialog)
}
return dialog
}
private fun setupRatio(bottomSheetDialog: BottomSheetDialog) {
val bottomSheet = bottomSheetDialog.findViewById<FrameLayout>(R.id.design_bottom_sheet)
val behavior = BottomSheetBehavior.from(bottomSheet!!)
val layoutParam = bottomSheet.layoutParams as ViewGroup.LayoutParams
layoutParam.height = getBottomSheetDialogDefaultHeight()
bottomSheet.layoutParams = layoutParam
behavior.state = BottomSheetBehavior.STATE_COLLAPSED
behavior.peekHeight = getBottomSheetDialogDefaultHeight()
}
private fun getBottomSheetDialogDefaultHeight(): Int {
return getWindowHeight() * 85 / 100
}
private fun getWindowHeight(): Int {
val displayMetrics = mContext.resources.displayMetrics
return displayMetrics.heightPixels
}
}
xml是这样的：

first实现了 Android 键盘，以便按下 Button id到的任何按钮sixth。但是这里的问题是，当键盘向上时，视图焦点设置在EditText上，但是EditText被键盘遮挡了。有没有办法让 BottomSheetDialogFragment 像 Activity 一样调整视图的大小？
[更新]
作为参考，样式应用如下。
- 调整大小
- 状态始终可见
- 调整大小，状态始终可见
我尝试了所有三种情况，但它没有奏效。
<style name="AppBottomSheetDialogTheme" parent="Theme.Design.BottomSheetDialog">
<item name="bottomSheetStyle">@style/AppModalStyle</item>
<item name="android:windowIsFloating">false</item>
<item name="android:statusBarColor">@android:color/transparent</item>
<item name="android:windowSoftInputMode">adjustResize|stateAlwaysVisible</item>
</style>
<style name="AppModalStyle" parent="Widget.Design.BottomSheet.Modal">
<item name="android:background">@drawable/shape_bottom_sheet</item>
</style>
