Question

我已经创建了AbstractActivity和AbstractFormActivity来摆脱一些样板代码，他们的内容可能与问题无关，但无论如何我都会发布它，也许我误解了一些东西，他们在那里：

public abstract class AbstractActivity extends ActionBarActivity {

    protected ObjectGraph graph;

    @Inject
    public Bus bus;

    @Inject
    public App app;

    @Override
    public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
        super.onCreate(savedInstanceState, persistentState);
        setContentView(getLayout());
        setupInjection();
    }

    public void setupInjection() {
        graph = ((App) getApplication()).createScopedGraph(getModule());
        graph.inject(this);
        bus.register(this);
        ButterKnife.inject(this);
    }

    protected abstract Object getModule();
    protected abstract int getLayout();
}

和

public abstract class AbstractFormActivity<T extends EntidadeBase> extends AbstractActivity implements Form<T> {

    protected T entity;
    protected Map<View, Boolean> formValidations;
    protected AbstractFormActivity() {
       formValidations = new HashMap<View, Boolean>();
    }

    @Override
    public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
        super.onCreate(savedInstanceState, persistentState);
    }

    protected boolean passedValidations() {
        for (View key : formValidations.keySet()) {
            if (!formValidations.get(key)) {
                return false;
            }
        }
        return true;
    }

    protected void validateAndSolidify() {
        if (passedValidations()) {
            solidify();
        }
        entity = null;
    }

    @Override
    public void validateMoreComplexFields() {
    }
}

最后，我创建了这些母亲活动的实施：

public class MercadoriaFormActivity extends AbstractFormActivity<Mercadoria> {

...

   @Override
   public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
        super.onCreate(savedInstanceState, persistentState);
    }

...

}

我的问题是没有调用onCreate方法。

非常感谢任何帮助。

Answer 1

您当前正在使用的

onCreate()版本已在Android 21中添加。您应该使用以下版本：

protected void onCreate (Bundle savedInstanceState)

Answer 2

我也遇到了同样的问题。几个小时后，我发现了我的错误，而是在 (savedInstanceState: Bundle, persistentState: PersistableBundle) 函数上覆盖了下面的一个。

Options -MultiViews
RewriteEngine On

# handle configurator 
RewriteRule ^(configurator)/(.+) $1.php?url=$2 [L,QSA,NC]

# To internally forward /dir/file to /dir/file.php
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/mypage/$1.php -f
RewriteRule ^(.+?)/?$ $1.php [L]

# front controller rule
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule ^(.*)$ index.php?url=$1 [L,QSA]

OnCreate没有调用Activity
