ViewPager沒有查看ID的片段

Question

我有一個查看分頁器，它有3個由FragmentActivity託管的選項卡片段。

我所試圖做的是單擊某個項目後，用一個新的來代替那些片段：

public class UserShopActivity extends FragmentActivity implements 
     UserItemsFragment.OnUserItemSelectedListener, 
     UserCategoriesFragment.OnUserCategoriesSelectedListener, 
     UserSelectedCategoryFragment.OnUserItemsSelectedListener { 

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

     mViewPager = new ViewPager(this); 
     mViewPager.setId(R.id.shop_pager); 
     setContentView(mViewPager); 
} 

... 

    @Override 
    public void onUserCategoriesSelected(String category_id) { 
     UserSelectedCategoryFragment fragment = new UserSelectedCategoryFragment(); 
     getSupportFragmentManager().beginTransaction() 
       .replace(R.id.shop_container, fragment) 
       .setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN) 
       .addToBackStack(null) 
       .commit(); 
} 
} 

但是我得到這個錯誤：

java.lang.IllegalArgumentException: No view found for id 0x7f070011 (com.ked.ai:id/shop_container) for fragment UserSelectedCategoryFragment{40f7bcf0 #3 id=0x7f070011}

我已經設置了容器的id在的setContentView viewpager這是shop_container：

<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/shop_pager" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 

    <FrameLayout 
     android:id="@+id/shop_container" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 

</android.support.v4.view.ViewPager> 

卜它找不到該ID。我該如何正確地更換它？

您不需要替換ViewPager中的片段即可實現FragmentPagerAdapter或FragmentStatePagerAdapter以在視圖尋呼機中顯示片段。

嘗試更改爲：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/shop_container" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" > 

<android.support.v4.view.ViewPager 
    android:id="@+id/shop_pager" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 




</android.support.v4.view.ViewPager> 
</FrameLayout> 

變化onCreate到：

public class UserShopActivity extends FragmentActivity implements 
     UserItemsFragment.OnUserItemSelectedListener, 
     UserCategoriesFragment.OnUserCategoriesSelectedListener, 
     UserSelectedCategoryFragment.OnUserItemsSelectedListener { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     //setContentView(R.layout.activity_user_profile); 
     setContentView(R.layout.yourlayoutname); 
     mViewPager = (ViewPager)findViewById(R.id.shop_pager); 


}
