簡單對話框中的ViewPager

我想在對話框中使用ViewPager，但不能史詩般的！這裏是所有的代碼。有要在對話框中顯示兩個片段：簡單對話框中的ViewPager

佈局

main.xml中

<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="match_parent" 
tools:context=".Main" > 

<Button 
    android:id="@+id/button" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="dialog" /> 

</RelativeLayout>

details.xml（片段佈局）

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" > 

<TextView 
    android:id="@+id/detailsText" 
    android:layout_width="wrap_content" 
    android:layout_height="match_parent" 
    android:layout_gravity="center_horizontal|center_vertical" 
    android:layout_marginTop="20dip" 
    android:text="Large Text" 
    android:textAppearance="?android:attr/textAppearanceLarge" 
    android:textSize="30dip" /> 

</LinearLayout>

圖像.xml（片段佈局）

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" > 

<ImageView 
    android:id="@+id/imageView1" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:src="@drawable/ic_launcher" /> 

</LinearLayout>

dialog.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:orientation="vertical" > 

<android.support.v4.view.ViewPager 
    android:id="@+id/pager" 
    android:layout_width="fill_parent" 
    android:layout_height="0dp" 
    android:layout_weight="1" /> 

<com.viewpagerindicator.CirclePageIndicator 
    android:id="@+id/indicator" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:padding="10dip" /> 

</LinearLayout>

Main.java

public class Main extends FragmentActivity { 

private Button button; 

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

    setupUIComponents(); 
    setupListeners(); 
} 

private void setupUIComponents() { 
    button = (Button) findViewById(R.id.button); 
} 

private void setupListeners() { 
    button.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      MyDialog dialog = new MyDialog(Main.this); 
      dialog.startDialog(); 
     } 
    }); 
} 
}

MyDialog.java

public class MyDialog extends FragmentActivity { 

private Dialog dialog; 
private Context context; 
private CirclePageIndicator mIndicator; 
private Main mMain; 
private ViewPager mPager; 
private FragmentAdapter mAdapter; 

public MyDialog(Context context) { 
    super(); 
    this.context = context; 
    this.mMain = (Main) context; 
} 

public void startDialog() { 
    dialog = new Dialog(context); 
    dialog.setContentView(R.layout.dialog); 

    mAdapter = new FragmentAdapter(mMain.getSupportFragmentManager()); 
    mPager = (ViewPager) dialog.findViewById(R.id.pager); 
    mPager.setAdapter(mAdapter); 

    mIndicator = (CirclePageIndicator) dialog.findViewById(R.id.indicator); 
    mIndicator.setViewPager(mPager); 
    mIndicator.setCurrentItem(0); 

    dialog.show(); 
} 

}

FragmentAdapter.java

public class FragmentAdapter extends FragmentPagerAdapter { 
public FragmentAdapter(FragmentManager fm) { 
    super(fm); 
} 

@Override 
public Fragment getItem(int which) { 
    switch (which) { 
     case 0: 
      ImageFragment imageFragment = new ImageFragment(); 
      return imageFragment; 
     case 1: 
      DetailFragment detailsFragment = new DetailFragment(); 
      return detailsFragment; 
    } 
    return null; 
} 

@Override 
public int getCount() { 
    return 2; 
} 

}

DetailsFragment.java

public class DetailFragment extends Fragment { 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
} 

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

} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    super.onCreateView(inflater, container, savedInstanceState); 
    View view = inflater.inflate(R.layout.details, container, false); 
    TextView textView = (TextView) view.findViewById(R.id.detailsText); 
    textView.setText("Testing"); 
    return view; 
} 
}

ImageFragment.java

public class ImageFragment extends Fragment { 

public ImageFragment() { 
} 

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

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

} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    super.onCreateView(inflater, container, savedInstanceState); 
    View view = inflater.inflate(R.layout.image, container, false); 
    ImageView imageView = (ImageView) view.findViewById(R.id.imageView1); 
    imageView.setImageDrawable(getResources().getDrawable(R.drawable.ic_launcher)); 
    return view; 
} 
}

要向上快速求和碼，Main.java啓動，點擊按鈕應在視圖尋呼機中啓動一個包含兩個片段的對話框。

有堆棧跟蹤：

再次，是有可能的片段顯示在一個對話框中viewpager？如果是這樣，我哪裏出錯了？

您的項目中是否遺漏了其他任何代碼？ –

編號當然，我正在使用支持包，以便能夠使用viewpager，因爲它沒有在「普通」Android SDK中提供。除此之外，這是我的項目的所有代碼。我不得不承認，雖然我沒有發佈任何像我使用的R.drawable.ic_launcer這樣的圖片，但是我發現這很令人着迷，在我發佈這個問題後不到一分鐘，你問了我這個問題！我希望能夠儘快讀取如此多的代碼行！ – BenjaminButton

請仔細閱讀視頻尋呼機中的對話框** https：//www.youtube.com/watch？v = pJG5ZuZtPKY ** –

再一次，是否有可能在對話框中的viewpager中顯示片段？

是的，但不是你嘗試過（如果我不缺你的代碼的東西）的方式，因爲它被放置在對話框中ViewPager將無法連接這些孩子Fragments。 4.2 API級別帶來nested Fragments（但也可以在較低版本中使用兼容性包的新版本），您應該使用它來顯示「在對話框片段中」。

在你Main活動中，您將創建一個DialogFragment並在DialogFragment你會設置的ViewPager並通過getChildFragmentManager()它的適配器。

而且，只需使用移動startDialog()方法在Main活動和不實例化一個新Activity，因爲這是不是Android的不言而喻的方式（在你的情況下，它的作品，因爲你沒有做任何事的）。

請仔細閱讀視頻尋呼機的對話框以供將來參考** https：// www。 youtube.com/watch?v=pJG5ZuZtPKY**。它會幫助很多人。 –
