      Android在kts中使用navigation及Args

      前言：

      ​ 之前在项目中使用过navigation，但都是以Groory的方式，最近一年多使用kts后忍不住把项目都改成kts的方式，不过其中也遇到不少坑，今天就讲解一下如何在kts中使用navigation和安全地传递参数Args。

      1.项目依赖导入：

      在libs.versions.toml文件下添加以下依赖：

      navigationFragmentKtx = "2.6.0"
navigationUiKtx = "2.6.0"
navigation-fragment = {group = "androidx.navigation",name = "navigation-fragment-ktx",version.ref = "navigationFragmentKtx"}
navigation-ui = {group = "androidx.navigation",name = "navigation-ui-ktx",version.ref = "navigationUiKtx"}
navigation-safe-args = { id = "androidx.navigation.safeargs.kotlin", version = "2.8.0" }

      2.app目录的build.gradle配置：

      plugins {
    alias(libs.plugins.androidApplication)
    alias(libs.plugins.jetbrainsKotlinAndroid)
    alias(libs.plugins.navigation.safe.args)
}
    implementation(libs.navigation.fragment)
    implementation(libs.navigation.ui)

      3.项目的build.gradle配置：

      plugins {
    alias(libs.plugins.androidApplication) apply false
    alias(libs.plugins.jetbrainsKotlinAndroid) apply false
    alias(libs.plugins.navigation.safe.args) apply false
}

      4.在布局添加导航组件：

      在res目录添加navigation——nav_graph文件

      <?XML version="1.0" encoding="utf-8"?>
<navigation xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/nav_graph"
    app:startDestination="@id/mainFragment">
    <fragment
        android:id="@+id/mainFragment"
        android:label="fragment_main"
        android:name="com.cloud.flowbusdemo.fragment.MainFragment"
        tools:layout="@layout/fragment_main">
        <action
            android:id="@+id/action_mainFragment_to_secondFragment"
            app:destination="@id/secondFragment"
            app:popEnterAnim="@anim/slide_in_left"
            app:popExitAnim="@anim/slide_out_right"
            app:enterAnim="@anim/slide_in_right"
            app:exitAnim="@anim/slide_out_left"/>
        <action
            android:id="@+id/action_mainFragment_to_mineFragment"
            app:destination="@id/mineFragment"
            app:enterAnim="@anim/slide_in_left"
            app:exitAnim="@anim/slide_in_right"
            app:popEnterAnim="@anim/slide_out_left"
            app:popExitAnim="@anim/slide_out_right" />
        <argument
            android:name="name"
            app:argType="string"
            android:defaultValue="xiaozhang"/>
        <argument
            android:name="age"
            app:argType="integer"
            android:defaultValue="1"/>
    </fragment>
    <fragment
        android:id="@+id/secondFragment"
        android:label="fragment_second"
        android:name="com.cloud.flowbusdemo.fragment.SecondFragment"
        tools:layout="@layout/fragment_second"/>
    <fragment
        android:id="@+id/mineFragment"
        android:name="com.cloud.flowbusdemo.fragment.MineFragment"
        android:label="fragment_mine"
        tools:layout="@layout/fragment_mine" />
</navigation>

            }
        }
    }
}

      12.SecondFragment代码：

      package com.cloud.flowbusdemo.fragment
import android.os.Bundle
import android.util.Log
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import androidx.fragment.app.Fragment
import androidx.lifecycle.lifecycleScope
import com.cloud.flowbusdemo.constants.Constants
import com.cloud.flowbusdemo.databinding.FragmentMineBinding
import com.cloud.flowbusdemo.databinding.FragmentSecondBinding
import com.cloud.flowbusdemo.flow.FlowBus
import com.cloud.flowbusdemo.model.MessageEvent
import kotlinx.coroutines.launch
/**

class SecondFragment : Fragment(){
    private val TAG = "SecondFragment"
    private var name: String? = null
    private var age: Int? = null
    private lateinit var binding: FragmentSecondBinding
    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {
        binding = FragmentSecondBinding.inflate(layoutInflater)
        initView()
        return binding.root
    }
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        arguments?.let {
            name = it.getString(Constants.ARG_PARAM_NAME)
            age = it.getInt(Constants.ARG_PARAM_AGE)
        }
        Log.i(TAG, "MainFragment 传递到 SecondFragment 的参数为 name = $name , age = $age")
        Log.d(TAG, "姓名:" + name + "年龄:" + age)
    }
    private fun initView() {
        binding.let {
            it.tvTitle.text = name
            it.tvAge.text  = age.toString()
        }
    }
}

      13.传递参数的方式：

      13.1使用bundle：

      binding.btnToSecondFragment.setOnClickListener(View.OnClickListener { v ->
          val bundle = Bundle()
          bundle.putString("name", "Michael")
          bundle.jsputInt("age", 30)
    Navigation.findNavController(v)
        .navigate(R.id.action_mainFragment_to_secondFragment, bundle)
})

      Android在kts中使用navigation及Args的方法

      13.2使用Safs安全方式传递：

      binding.btnToMineFragment.setOnClickListener{v ->
    val bundle: Bundle = MainFragmentArgs("haha",20).toBundle()
     Navigation.findNavController(v).navigate(R.id.action_mainFragment_to_mineFragment,bundle)
}

      Android在kts中使用navigation及Args的方法

      14.实现效果如下：
