目前我在 java 環(huán)境中工作并嘗試開始使用 kotlin。我的第一堂課是 Java 類型，下一堂課是 Kotlin 類型。我的第一堂課如下public class FragmentDashboard extends BaseFragment {Button btnLaunchComplaint;TextView tvSupport; public static FragmentDashboard getInstance(Bundle bundle, String title, int icon) { FragmentDashboard fragment = new FragmentDashboard(); fragment.setArguments(bundle); fragment.setFragmentTitle(title); fragment.setFragmentIconId(icon); return fragment; } @Override protected void initializeControls(View v) { btnLaunchComplaint = v.findViewById(R.id.btnLaunchComplaint); tvSupport = v.findViewById(R.id.tvSupport); } @Override protected int getLayoutResourceId() { return R.layout.fragment_dashborad_layout; } @Override protected void initializationBundle(Bundle bundle) { } @Override protected void attachListeners() { btnLaunchComplaint.setOnClickListener(this); tvSupport.setOnClickListener(this); } @Override protected void initializeData() { animateViews(); } @Override public void onClick(View view) { switch (view.getId()) { case R.id.btnLaunchComplaint: FragmentForm fragmentForm = FragmentForm.getInstance(new Bundle(), "", -1); replaceFragment(fragmentForm, false, false, true, ""); break; case R.id.tvSupport: FragmentSupport fragmentSupport = FragmentSupport.getInstance(new Bundle(), "", -1); replaceFragment(fragmentSupport, false, false, true, ""); break; } super.onClick(view); } @Override public void onResume() { super.onResume(); setNavigationTitle(getResources().getString(R.string.wasa_home)); } private void animateViews() { Animation animateTopDown = AnimationUtils.loadAnimation(getActivity(), R.anim.left_in); btnLaunchComplaint.startAnimation(animateTopDown); }}

java 中的靜態(tài)方法可以通過 kotlin 中的 @JvmStatic 注釋轉(zhuǎn)換為伴隨對(duì)象方法：
class FragmentRegisterComplaint : BaseFragment() {
companion object {
@JvmStatic
fun getInstance(bundle: Bundle, title: String, icon: Int): FragmentRegisterComplaint {
val fragment = FragmentRegisterComplaint()
fragment.arguments = bundle
fragment.setFragmentTitle(title)
fragment.setFragmentIconId(icon)
return fragment
}
}
}

Kotlin 已經(jīng)用 object 和 comapnion object 替換了 static
您可以在類內(nèi)的伴生對(duì)象中將您想要的內(nèi)容定義為靜態(tài)。
像下面
companion object {
fun getInstance(bundle: Bundle, title: String, icon: Int): FragmentRegisterComplaint {
val fragment = FragmentRegisterComplaint()
fragment.arguments = bundle
fragment.setFragmentTitle(title)
fragment.setFragmentIconId(icon)
return fragment
}
}
}
現(xiàn)在在你的java類中你可以使用它作為
YorFragmentName.companion.method()
