- SignupActivity 만들기
서버 연결 시 이름,아이디,비밀번호가 모두 전달되어야 하므로 한 칸이라도 비었을때 response가 fail되기 때문에 그 부분에 error code를 넣음.
...
if (response.isSuccessful) {
Toast.makeText(this@SignupActivity, "회원가입 완료!", Toast.LENGTH_SHORT).show()
if (response.body()!!.success) {
val intent = Intent(this@SignupActivity, LoginActivity::class.java)
startActivity(intent)
finish()
}
}
else
{
showError(response.errorBody())
}
...private fun showError(error : ResponseBody?)
{
val e = error ?: return
val ob = JSONObject(e.string())
Toast.makeText(this, ob.getString ("message"),Toast. LENGTH_SHORT).show()
}- 자동로그인
sharedPreference 사용하여 아이디와 비밀번호를 저장함
fun autoLogin(){
val preference = this.getSharedPreferences("temp", Context.MODE_PRIVATE)
val editor: SharedPreferences.Editor = preference!!.edit()
if(preference.getString("id", "").isNullOrBlank()||preference.getString("pw", "").isNullOrBlank())
{
init()
}
else
{
Toast.makeText(this, "자동로그인 되었습니다", Toast.LENGTH_SHORT).show()
val gotologinintent = Intent(this, MainActivity2::class.java)
startActivity(gotologinintent)
finish()
}
}체크박스에 체크가 되어있을 때만 자동로그인 되어야 함
private fun checkboxLogin() {
val preference = this.getSharedPreferences("temp", Context.MODE_PRIVATE)
val editor: SharedPreferences.Editor = preference!!.edit()
if (cb_autologin.isChecked) {
editor.putString("id", et_id.text.toString())
editor.putString("pw", et_pw.text.toString())
editor.clear()
editor.apply()
Toast.makeText(this, "다음부터 자동으로 로그인됩니다.", Toast.LENGTH_LONG).show()
}
else
{
editor.remove("id")
editor.remove("pw")
editor.clear()
editor.apply()
}
}- RecyclerView
recyclerview를 만들기 위해 adapter와 viewholder 만듦
adapter는 아이템마다 뷰홀더를 생성하고 데이터를 전달.
click 인터페이스 구현
class ProfileAdapter(var context : Context): RecyclerView.Adapter<ProfileViewHolder>() {
var data= mutableListOf<SampleDATA>()
interface ItemClick
{
fun onClick(view: View, position: Int)
}
var itemClick: ItemClick? = null
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ProfileViewHolder {
val view=LayoutInflater.from(context).inflate(R.layout.profile_item,parent,false)
return ProfileViewHolder(view)
}
override fun onBindViewHolder(holder: ProfileViewHolder, position: Int) {
holder.onBind(data[position])
if(itemClick != null)
{
holder.itemView.setOnClickListener { v ->
itemClick?.onClick(v, position)
}
}
}
override fun getItemCount(): Int =data.size
}fragment 코드에 아이템 클릭 리스너 구현
내가 클릭한 position에 있는 title과 subtitle을 전달해줌
profileAdapter.itemClick=object :ProfileAdapter.ItemClick{
override fun onClick(view: View, position: Int) {
val intent = Intent(context, DetailActivity::class.java)
intent.putExtra("title", profileAdapter.data[position].title)
intent.putExtra("subtitle", profileAdapter.data[position].subTitle)
startActivity(intent)
}- bottomnavigation
- tablayout
viewpageradapter 생성
class SampleViewPagerAdapter (fm:FragmentManager)
:FragmentStatePagerAdapter(fm, BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT){
var fragments = listOf<Fragment>()
override fun getItem(position: Int): Fragment = fragments[position]
override fun getCount(): Int = fragments.size
}tablayout 구현, tablayout에 viewpager 구현
첫번째 탭 InfoFragment()
두번째 탭 OtherFragment()
class FirstFragment : Fragment() {
private lateinit var viewpagerAdapter:SampleViewPagerAdapter
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
// Inflate the layout for this fragment
val view = inflater.inflate(R.layout.fragment_first, container, false)
viewpagerAdapter= SampleViewPagerAdapter(childFragmentManager)
viewpagerAdapter.fragments= listOf(
InfoFragment(),
OtherFragment()
)
return view
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
sample_tab_viewpager.adapter=viewpagerAdapter
sample_tab.setupWithViewPager(sample_tab_viewpager)
sample_tab.apply{
getTabAt(0)?.text="INFO"
getTabAt(1)?.text="OTHER"
}
}
}bottom navigation과 viewpager 구현
viewPagerAdapter= SampleViewPagerAdapter(supportFragmentManager)
viewPagerAdapter.fragments= listOf(
FirstFragment(),
RecyclerFragment(),
ThirdFragment()
)
sample_viewpager.adapter=viewPagerAdapter
sample_viewpager.addOnPageChangeListener(object : ViewPager.OnPageChangeListener {
override fun onPageScrollStateChanged(state: Int) {}
override fun onPageScrolled(
position: Int,
positionOffset: Float,
positionOffsetPixels: Int
) {}
override fun onPageSelected(position: Int) {
bottomNavigationView.menu.getItem(position).isChecked = true
}
})
bottomNavigationView.setOnNavigationItemSelectedListener{
var index by Delegates.notNull<Int>()
when(it.itemId){
R.id.menu_camera ->index=2
R.id.menu_brush ->index=1
else -> index=0
}
sample_viewpager.currentItem=index
true
