圖片取自系統內建圖片

File -> New -> Vector Asset

使用 SVG 向量圖片

在專案的 build.gradle 需加入 vectorDrawables.useSupportLibrary = true。需向下相容，因為 Android 6(SDK 23)之前，尚未支援向量圖片格式。

android {  
   ...
   defaultConfig {  
   ...
     vectorDrawables.useSupportLibrary = true  
    }  
 }  

PharmacyDetailActivity

class PharmacyDetailActivity : AppCompatActivity() {

    private val data by lazy { intent.getSerializableExtra("data") as? Feature }

    private val name by lazy { data?.properties?.name }
    private val maskAdultAmount by lazy { data?.properties?.mask_adult }
    private val maskChildAmount by lazy { data?.properties?.mask_child }
    private val phone by lazy { data?.properties?.phone }
    private val address by lazy { data?.properties?.address }

    private lateinit var binding: ActivityPharmacyDetailBinding

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
//        setContentView(R.layout.activity_pharmacy_detail)

        binding = ActivityPharmacyDetailBinding.inflate(layoutInflater)
        setContentView(binding.root)

        initView()

    }

    private fun initView() {
        binding.tvName.text = name ?: "資料發生錯誤"
        binding.tvAdultAmount.text = maskAdultAmount.toString()
        binding.tvChildAmount.text = maskChildAmount.toString()
        binding.tvPhone.text = phone
        binding.tvAddress.text = address
    }
}
