Android在kts中使用navigation及Args的方法
更新時(shí)間：2024年10月25日 11:20:43 作者：淡淡的香煙
在Android項(xiàng)目中使用Kotlin腳本（kts）替代Groovy配置navigation和Args,需添加相關(guān)依賴,并在build.gradle中進(jìn)行配置,文章詳細(xì)介紹了如何在kts中使用navigation進(jìn)行頁(yè)面導(dǎo)航和參數(shù)傳遞,介紹了使用Bundle和Safe Args兩種方式安全傳遞參數(shù)
Android在kts中使用navigation及Args
前言：
? 之前在項(xiàng)目中使用過(guò)navigation，但都是以Groory的方式，最近一年多使用kts后忍不住把項(xiàng)目都改成kts的方式，不過(guò)其中也遇到不少坑，今天就講解一下如何在kts中使用navigation和安全地傳遞參數(shù)Args。
1.項(xiàng)目依賴導(dǎo)入：
在libs.versions.toml文件下添加以下依賴：
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目錄的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.項(xiàng)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.在布局添加導(dǎo)航組件：
在res目錄添加navigation——nav_graph文件
<?xml version="1.0" encoding="utf-8"?>
<navigation xmlns:android="http://schemas.android.com/apk/res/android"

<argument

</fragment>

binding.let {
it.tvTitle.text = name
it.tvAge.text = age.toString()

}13.傳遞參數(shù)的方式：
13.1使用bundle：
binding.btnToSecondFragment.setOnClickListener(View.OnClickListener { v ->
val bundle = Bundle()
bundle.putString("name", "Michael")
bundle.putInt("age", 30)
Navigation.findNavController(v)
.navigate(R.id.action_mainFragment_to_secondFragment, bundle)
})
13.2使用Safs安全方式傳遞：
binding.btnToMineFragment.setOnClickListener{v ->
val bundle: Bundle = MainFragmentArgs("haha",20).toBundle()
Navigation.findNavController(v).navigate(R.id.action_mainFragment_to_mineFragment,bundle)
}
