android-target-instructions库跳过按钮失效，求助实现剩余步骤跳过

我正在尝试集成android-target-instructions库，希望实现点击跳过按钮来跳过剩余引导步骤。根据库文档提示调用.finish()方法，但没有任何效果。我尝试重新加载Fragment，但引导步骤仍然存在，必须在点击跳过按钮时将其关闭。

现有代码 #

private fun showInstructions() {
        val userCredentials = CommonUtilities.getUserTokenAndName(requireActivity())
        val sharedPrefs = PreferenceManager.getDefaultSharedPreferences(requireActivity())
        if (!userCredentials.first.isNullOrEmpty()
            && !userCredentials.second.isNullOrEmpty()
//            && CommonUtilities.isHomeFirstTimeOpening(requireActivity())
        ) {
            val target1 = SimpleTarget.Builder(requireActivity())
                .setTarget(binding.oscarChiefIc)
                .setTitle("Floating Action Button")
                .setHighlightRadius(100f) // Circle shape
                .setDescription("Discover culinary inspirations - click to explore recipes and ingredients.")
                .setMessageLayoutResId(R.layout.instruction_layout) // This is custom layout
                .build()
            val target2 = SimpleTarget.Builder(requireActivity())
                .setTarget(binding.scanIcon)
                .setTitle("Floating Action Button")
                .setMessageLayoutResId(R.layout.instruction_layout) // This is custom layout
                .setHighlightRadius(100f) // Circle shape
                .setDescription("Scan all your products and add it to your cart.")
                .build()

            val inflater = LayoutInflater.from(requireContext())
            val popupView: View = inflater.inflate(R.layout.popup_message_view, null)

            val width = LinearLayout.LayoutParams.WRAP_CONTENT
            val height = LinearLayout.LayoutParams.WRAP_CONTENT
            val focusable = false
            val popupWindow = PopupWindow(popupView, width, height, focusable)
            val skipBtn = popupView.findViewById<Button>(R.id.skipBtn)
         
            val targets = arrayListOf(target1, target2)

            view?.post {
                popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0)
            }
            skipBtn.setOnClickListener {
                popupWindow.dismiss()
                parentFragmentManager.beginTransaction()
                    .replace(R.id.container_frameLayout, NewHomeFragment()).addToBackStack(null).commit()
            }
            TargetInstructions.with(requireActivity())
                .setTargets(targets)
                .start()
        }
        sharedPrefs.edit().putBoolean(HOME_FIRST_RUN, false).apply()
    }

问题核心是你没有持有TargetInstructions的实例引用，导致无法调用.finish()方法终止引导流程。按以下方式修改代码：

1. 保存TargetInstructions实例：将链式调用拆分，用变量保存TargetInstructions实例，避免调用.start()后丢失引用。
2. 在跳过按钮点击时执行finish()：在skipBtn的点击事件中，先调用实例的.finish()方法关闭引导，再处理弹窗关闭和Fragment跳转。

修改后的代码：

private fun showInstructions() {
        val userCredentials = CommonUtilities.getUserTokenAndName(requireActivity())
        val sharedPrefs = PreferenceManager.getDefaultSharedPreferences(requireActivity())
        if (!userCredentials.first.isNullOrEmpty()
            && !userCredentials.second.isNullOrEmpty()
//            && CommonUtilities.isHomeFirstTimeOpening(requireActivity())
        ) {
            val target1 = SimpleTarget.Builder(requireActivity())
                .setTarget(binding.oscarChiefIc)
                .setTitle("Floating Action Button")
                .setHighlightRadius(100f) // Circle shape
                .setDescription("Discover culinary inspirations - click to explore recipes and ingredients.")
                .setMessageLayoutResId(R.layout.instruction_layout) // This is custom layout
                .build()
            val target2 = SimpleTarget.Builder(requireActivity())
                .setTarget(binding.scanIcon)
                .setTitle("Floating Action Button")
                .setMessageLayoutResId(R.layout.instruction_layout) // This is custom layout
                .setHighlightRadius(100f) // Circle shape
                .setDescription("Scan all your products and add it to your cart.")
                .build()

            val inflater = LayoutInflater.from(requireContext())
            val popupView: View = inflater.inflate(R.layout.popup_message_view, null)

            val width = LinearLayout.LayoutParams.WRAP_CONTENT
            val height = LinearLayout.LayoutParams.WRAP_CONTENT
            val focusable = false
            val popupWindow = PopupWindow(popupView, width, height, focusable)
            val skipBtn = popupView.findViewById<Button>(R.id.skipBtn)
         
            val targets = arrayListOf(target1, target2)

            // 保存TargetInstructions实例
            val targetInstructions = TargetInstructions.with(requireActivity())
                .setTargets(targets)

            view?.post {
                popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0)
            }
            skipBtn.setOnClickListener {
                popupWindow.dismiss()
                // 调用finish()终止引导流程
                targetInstructions.finish()
                parentFragmentManager.beginTransaction()
                    .replace(R.id.container_frameLayout, NewHomeFragment()).addToBackStack(null).commit()
            }
            // 启动引导
            targetInstructions.start()
        }
        sharedPrefs.edit().putBoolean(HOME_FIRST_RUN, false).apply()
    }

额外注意事项：

• 确认自定义布局instruction_layout中的确认按钮正确关联库的回调，保证引导流程能正常推进。
• 检查HOME_FIRST_RUN的逻辑，确保首次启动判断准确，避免引导重复触发。
