【Android】Dialog弹出软键盘时把布局顶起来的实现

demo效果如下：

代码实现

class AICodeDialog(val activity: BaseActivity) : Dialog(activity),View.OnClickListener, AIRedPkgView {private lateinit var mBgView: Viewprivate lateinit var mClose: Viewprivate lateinit var mUse: Viewprivate lateinit var mEditText: McdEditTextViewprivate var mCode: String? = nullprivate var mPresenter: AIRedPkgPresenter? = nulloverride fun show() {if (context is Activity && ((context as Activity).isFinishing || (context as Activity).isDestroyed)) {return}mCode?.let {mEditText.setText(it.toCharArray(), 0, it.length)mEditText.setSelection(it.length)mCode = null}super.show()}fun setCode(code: String?) {mCode = code}override fun hide() {ExtendUtil.hideSoftInput(context, mEditText)mCode = nullmEditText.setText("")super.hide()}init {initView()}private fun initView() {val view = LayoutInflater.from(context).inflate(R.layout.reward_ai_code_dialog, null)setContentView(view)mClose = findViewById(R.id.iv_close)mEditText = findViewById(R.id.et_code)mBgView = findViewById(R.id.fl_demo)mUse = findViewById(R.id.iv_use)mClose.setOnClickListener(this)mBgView.setOnClickListener(this)mUse.setOnClickListener(this)setOnShowListener { showKeyboard() }setCanceledOnTouchOutside(true)val params = window?.attributesparams?.width = AppConfigLib.sScreenWidthparams?.height = WindowManager.LayoutParams.MATCH_PARENTparams?.gravity = android.view.Gravity.BOTTOMwindow?.attributes = paramswindow?.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)window?.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION)window?.setBackgroundDrawableResource(R.color.lib_transparent)}private fun showKeyboard() {mEditText.requestFocus()mEditText.postDelayed({if (isShowing) {ExtendUtil.toggleSoftInput(context)}}, 200)}override fun onClick(v: View?) {when (v?.id) {R.id.iv_use -> {TrackUtil.trackPopupClick(AppTrackPage.AIPhoto,"提示弹窗","活动协议","使用")if (!AppConfigLib.isLogin()) {RouterUtil.resolve(context, GlobalPageRouterConfig.COMPONENT_NAME.USER,GlobalPageRouterConfig.ACTION_NAME.ACTION_LOGIN)return}useClick()}R.id.iv_close,R.id.fl_demo -> {TrackUtil.trackPopupClick(AppTrackPage.AIPhoto,"提示弹窗","活动协议","不同意")closeDialog()}}}private fun closeDialog() {ExtendUtil.hideSoftInput(context, mEditText)dismiss()}private fun useClick() {if (ExtendUtil.isFastDoubleClick()) return //防止快速点击val code = mEditText.text.toString().trim()if (code.isEmpty()) {DialogUtil.showShortPromptToast(context, "请输入红包码")return}if (mPresenter == null) {mPresenter = AIRedPkgPresenter(context, this)}mPresenter?.requestAICode(code)}override fun showLoadingDialog(message: String?) {activity.showProgressDialog("")}override fun hideLoadingDialog() {activity.dismissProgressDialog()}override fun showErrorMsg(msg: String?) {DialogUtil.showShortPromptToast(context, msg ?: "红包码识别失败")}override fun onAICoverSuccess() {closeDialog()}
}

软键盘和EditText保持一定间距的实现思路，可以设置EditText 的 paddingBottom
