1.先導入函示庫(build.gradle: Module)

dependencies {
   implementation 'com.google.android.material:material:1.3.0-alpha01'
}

2.程式碼範例

SnackBar用法

一般用法

Snackbar.make(view, "消息:測試", Snackbar.LENGTH_SHORT).show()

文字顏色和背景顏色

val snackBar = Snackbar.make(view, "消息:測試", Snackbar.LENGTH_SHORT)
val snackBarView = snackBar.view

snackBarView.run {
      setBackgroundColor(Color.RED)
      findViewById<TextView>(R.id.snackbar_text).setTextColor(Color.YELLOW)
}

snackBar.show()

設置點擊事件

Snackbar.make(view, "消息:測試", Snackbar.LENGTH_SHORT)
     .setAction("確定") {
           Toast.makeText(this, "打開訊息", Toast.LENGTH_SHORT).show()
      }.show()

設置點擊文字顏色

Snackbar.make(view, "消息:測試", Snackbar.LENGTH_SHORT)
     .setActionTextColor(Color.YELLOW)
     .setAction("確定") {
          Toast.makeText(this, "打開訊息", Toast.LENGTH_SHORT).show()
     }.show()

设置SnackBar監聽

Snackbar.make(view, "消息:測試", Snackbar.LENGTH_SHORT)
     .setActionTextColor(Color.YELLOW)
     .setAction("確定") {
           Toast.makeText(this, "打開訊息", Toast.LENGTH_SHORT).show()
     }
     .addCallback(object : Snackbar.Callback() {
         override fun onShown(sb: Snackbar?) {
            super.onShown(sb)
            Toast.makeText(this@MainActivity, "onShown",Toast.LENGTH_SHORT).show()
         }

         override fun onDismissed(transientBottomBar: Snackbar?, event: Int) {
            super.onDismissed(transientBottomBar, event)
            Toast.makeText(this@MainActivity, "onDismissed", Toast.LENGTH_SHORT).show()
         }
      })
      .show()
