Android MVP模式实现组件和业务逻辑分离

1，Activity代码展示，只需要一下3行重要代码即可完成任何复杂的逻辑

/** * 登录界面 * * @author lipanquan */public class LoginActivity extends MVPBaseActivity {

@Override    protected void setTitle() {        getAOP().setTitle();    }

@Override    protected ActivityPresenter initAOP() {        return new LoginActivityPresenter(this);    }

@Override    public boolean onKeyUp(int keyCode, KeyEvent event) {        return getAOP().onKeyUp(keyCode, event);    }

}

2，登录界面的逻辑控制代码/** * 登录界面的逻辑控制 * Created by lipanquan on 2016/12/7. */public class LoginActivityPresenter extends ActivityPresenter implements        CompoundButton.OnCheckedChangeListener, View.OnTouchListener, View.OnFocusChangeListener, View.OnClickListener {

private static final String KEY_IS_REMEMBER_ME = "isRememberMe";    private static final String KEY_USERNAME = "userName";    private static final String KEY_PASSWORD = "pwd";

@Override    public void setTitle() {        setTitle(R.string.title_login);        setLeft(true, R.drawable.selector_btn_back, R.string.string_back);    }

/**     * 登录界面activity     */    private final MVPBaseActivity activity;
