這篇文章給大家介紹Android中怎么利用MVP實(shí)現(xiàn)登錄注冊(cè)功能,內(nèi)容非常詳細(xì),感興趣的小伙伴們可以參考借鑒,希望對(duì)大家能有所幫助。
成都創(chuàng)新互聯(lián)公司-專業(yè)網(wǎng)站定制、快速模板網(wǎng)站建設(shè)、高性價(jià)比烏蘇網(wǎng)站開發(fā)、企業(yè)建站全套包干低至880元,成熟完善的模板庫,直接使用。一站式烏蘇網(wǎng)站制作公司更省心,省錢,快速模板網(wǎng)站建設(shè)找我們,業(yè)務(wù)覆蓋烏蘇地區(qū)。費(fèi)用合理售后完善,10年實(shí)體公司更值得信賴。model包:
import com.bwei.mvps.bean.UserBean; public interface IUserModel { void setFirstName(String firstName); void setLastName(String lastName); String getFirstName(); String getLastName(); //根據(jù)id獲取對(duì)象 UserBean load(int id); }
import android.util.Log; import com.bwei.mvps.bean.UserBean; public class UserModel implements IUserModel { @Override public void setFirstName(String firstName) { Log.i("xxx", firstName); } @Override public void setLastName(String lastName) { Log.i("xxx", lastName); } @Override public String getFirstName() { return null; } @Override public String getLastName() { return null; } @Override public UserBean load(int id) { //查詢數(shù)據(jù)庫或聯(lián)網(wǎng)獲取數(shù)據(jù) Log.i("fff", id + ""); return new UserBean("張", "三"); } }
View包
public interface UserView { void setFirstName(String firstName); void setLastName(String lastName); int getId(); String getFirstName(); String getLastName(); }
presenter包:
import android.util.Log; import com.bwei.mvps.MainActivity; import com.bwei.mvps.bean.UserBean; import com.bwei.mvps.model.IUserModel; import com.bwei.mvps.model.UserModel; import com.bwei.mvps.view.UserView; public class UserPresenter { private UserView userview; private final IUserModel iUserModel; public UserPresenter(UserView userview) { this.userview = userview; iUserModel = new UserModel(); } //保存數(shù)據(jù) public void saveUser(int id, String firstName, String lastName) { UserBean userBean = iUserModel.load(id); Log.i("sss", "id:" + id + ",firstName:" + firstName + ",lastName:" + lastName); } //查詢數(shù)據(jù) public void find(int id) { UserBean userBean = iUserModel.load(id); String firstName = userBean.getFirstName(); String lastName = userBean.getLastName(); userview.setFirstName(firstName); userview.setLastName(lastName); Log.i("aaa", "id:" + id + ",firstName:" + firstName + ",lastName:" + lastName); } }
