- 使用Anko，简化代码
build.gradle 依赖 anko
implementation 'org.jetbrains.anko:anko-common:+'
import android.support.v7.app.AppCompatActivity
import android.os.Bundle
import android.view.View
import kotlinx.android.synthetic.main.activity_main.*
import org.jetbrains.anko.toast
class MainActivity : AppCompatActivity(), View.OnClickListener {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
btn.text ="按钮1"
btn.setOnClickListener(this)
btn2.setOnClickListener(this)
}
override fun onClick(view: View) {
val id = view.id
when (id) {
R.id.btn -> btnClick()
R.id.btn2 ->{
toast("按钮2点击")
}
else -> {
}
}
}
fun btnClick() {
toast("按钮点击")
}
}
2.页面跳转
val intent = Intent(this@MainActivity,PayssionActivity::class.java)
startActivity(intent)
