带有图像的 ViewPager 导致应用程序崩溃
ViewPager with Image Causes the app crash
你好，我使用了 ViewPager 并制作了一个介绍滑块，除了幻灯片数量增加时程序崩溃和挂起外，一切正常，因为我使用了图像，加载图像会导致内存不足错误并使我不使用的应用程序崩溃不知道如何解决这个问题
这些是我的程序代码
private val introSliderAdapter = IntroSliderAdapter(
listOf(
IntroSliderModel(
"test",
"test2",
R.drawable.slider1
),
IntroSliderModel(
"test",
"test2",
R.drawable.slider2
)
)
)
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.intro_activity)
introSliderViewPager.adapter = introSliderAdapter
}
这是我的适配器
class IntroSliderAdapter(private val introSlides: List<IntroSliderModel>) :
RecyclerView.Adapter<IntroSliderAdapter.IntroSliderViewholder>(){
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): IntroSliderViewholder {
return IntroSliderViewholder(LayoutInflater.from(parent.context).inflate(R.layout.slider_item_container,parent,false))
}
override fun getItemCount(): Int {
return introSlides.size
}
override fun onBindViewHolder(holder: IntroSliderViewholder, position: Int) {
holder.bind(introSlides[position])
}
inner class IntroSliderViewholder(view: View) : RecyclerView.ViewHolder(view){
private val textTitle = view.findViewById<MaterialTextView>(R.id.textTitle)
private val textDescription = view.findViewById<MaterialTextView>(R.id.textDescription)
private val imageIcon = view.findViewById<AppCompatImageView>(R.id.imageSlideIcon)
fun bind(introSlides: IntroSliderModel) {
textTitle.text = introSlides.title
textDescription.text = introSlides.description
imageIcon.setImageResource(introSlides.icon)
}
}
}

你应该考虑使用一些图片加载库：Glide / Picasso / Fresco
