我已经玩了几个星期的MVP模式,我已经到了需要上下文来启动service和访问的地步Shared Preferences.
我已经读过MVP的目的是将视图与逻辑分离,并且context在一个内部Presenter可以打败那个目的(如果我错了,请纠正我).
目前,我有一个看起来像这样的LoginActivity:
LoginActivity.java
public class LoginActivity extends Activity implements ILoginView {
private final String LOG_TAG = "LOGIN_ACTIVITY";
@Inject
ILoginPresenter mPresenter;
@Bind(R.id.edit_login_password)
EditText editLoginPassword;
@Bind(R.id.edit_login_username)
EditText editLoginUsername;
@Bind(R.id.progress)
ProgressBar mProgressBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
MyApplication.getObjectGraphPresenters().inject(this);
mPresenter.setLoginView(this, getApplicationContext());
}
@Override
public void onStart() {
mPresenter.onStart();
ButterKnife.bind(this);
super.onStart();
}
@Override
public void onResume() {
mPresenter.onResume();
super.onResume();
}
@Override
public void onPause() {
mPresenter.onPause();
super.onPause();
}
@Override
public void onStop() …我需要在模型中使用活动的Context,同时在android中使用MVP来获取所有已安装的应用程序的列表.访问上下文的正确方法是什么,或者在遵循MVP模式时实现相同的任何替代方法.
这是课程:
public class MainActivity extends BaseActivity
implements MainView,View.OnClickListener {
private MainPresenter mPresenter;
private Button sendButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
createPresenter();
}
private void init(){
sendButton= (Button) findViewById(R.id.button_send);
sendButton.setOnClickListener(this);
}
private void createPresenter() {
mPresenter=new MainPresenter();
mPresenter.addView(this);
}
@Override
public void onClick(View view) {
switch (view.getId()){
case R.id.button_send:
mPresenter.onSendButtonClick();
break;
}
}
@Override
public void openOptionsActivity() {
Intent intent=new Intent(this,OptionsActivity.class);
startActivity(intent);
}
}
公共类MainPresenter扩展BasePresenter {
MainModel model;
public void onSendButtonClick(){
model.getListOfAllApps();
}
@Override
public void …
