Android 从碎片活动引发事件

我想从

ActivityFragment

类调用方法，但我怀疑我没有完全理解这个

ActionBar Fragments

的工作方式

这是创建

ActionBar

选项卡的类的主要代码：

public class OrdersActivity extends ActionBarActivity {

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_orders);

    android.support.v7.app.ActionBar actionBar = getSupportActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
    actionBar.setDisplayShowTitleEnabled(false);

    ActionBar.Tab tab = actionBar.newTab()
            .setText("Nowe")
            .setTabListener(new TabListener<TabNewFragment>(
                    this, "new", TabNewFragment.class));
    actionBar.addTab(tab);

    tab = actionBar.newTab()
            .setText("Wykonywane")
            .setTabListener(new TabListener<TabInProgFragment>(
                    this, "in_progress", TabInProgFragment.class));
    actionBar.addTab(tab);

    tab = actionBar.newTab()
            .setText("Archiwum")
            .setTabListener(new TabListener<TabArchFragment>(
                    this, "archived", TabArchFragment.class));
    actionBar.addTab(tab);
}

和我的

碎片活动

课程：

public class TabNewFragment extends Fragment {

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        View mainView = inflater.inflate(R.layout.activity_tab_new, container, false);
        return mainView;
    }
}

public class TabNewActivity extends FragmentActivity {

Button mAddNew;
private ProductItemAdapter mAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_tab_new);

    Toast.makeText(getApplicationContext(),"aaaaa",Toast.LENGTH_LONG).show();
    productTable = msc.getTable(Products.class);

    mAddNew=(Button)findViewById(R.id.buttonAdd);
    mAddNew.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            addProductItem(v);
        }
    });
    mAdapter = new ProductItemAdapter(this, R.layout.row_product_list);
    ListView listViewProducts = (ListView) findViewById(R.id.listViewProducts);
    listViewProducts.setAdapter(mAdapter);
}

public void addProductItem(View view) {

    Products item = new Products();
    //more code....
}

活动选项卡\u new.xml

如下所示：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="275dp"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context="azure.holdersystem.View.OrdersActivityTabs.TabNewActivity">        

    <Button
        style="?android:attr/buttonStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/custom_btn_1"
        android:text="Dodaj produkt"
        android:id="@+id/buttonAdd"
        android:layout_marginTop="10dp"
        android:layout_below="@+id/editText"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentStart="true" />
</RelativeLayout>.....

.....

当我点击按钮时，一切正常，但没有任何事件出现，甚至这个简单的祝酒词也没有出现

我做错了什么

嗯，很简单。。。只需删除FragmentActivity并将metods添加到fragment类。

您的代码是actionbar activity，但启动时此TabNewActivity是什么？这是用于布局的活动。activity\u tab\u new
