private fun ShowData() {
var tip = mfirebasedatabase!!.getReference("Model").orderByChild("a")
options = FirebaseRecyclerOptions.Builder<Model>().setQuery(tip,Model::class.java).build()
mfirebaseRecyclerAdapter = object : FirebaseRecyclerAdapter<Model,ViewHolder>(options!!) {
override fun onBindViewHolder(viewHolder: ViewHolder,i: Int,model: Model) {
viewHolder.setDetails(applicationContext,model.image,model.title)
}
override fun onCreateViewHolder(parent: ViewGroup,viewType: Int): ViewHolder {
val itemview = LayoutInflater.from(parent.context).inflate(R.layout.row,parent,false)
val viewHolder = ViewHolder(itemview)
var sh :Button = itemview.findViewById<Button>(R.id.buttontoShare)
sh.setonClickListener {
// how to get the Model.image so that i can implement
//share intent to share data to other apps?
}
为什么为什么为什么!!!!!!
import java.security.MessageDigest;
import java.util.Random;
......
默认情况下已安装Java 8。
为什么不呢？
解决方法
因为Java类名区分大小写

- Since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language用于脚本编写，所以我建议re-considering using Beanshell
- 您可能还想看看__digest() function，因为可能根本不需要编写脚本

不！ 导入java.security.messageDigest是输入错误。
java.security.MessageDigest。
为什么不呢？为什么不呢？
没有错字。
