我在全屏显示 DialogFragment 时遇到了一些问题。在我的应用程序中，我有一个 fragment ，当您单击某个按钮时，它会调用 DialogFragment。但是 DialogFragment 只是填充 fragment 的区域(在操作栏下方)。我希望它像这样填满整个屏幕:http://img845.imageshack.us/img845/8682/myimage2.png

有什么帮助吗？

     public class ItensActivity extends Fragment {
             ... 
            public void openDialogItens()
            {       
                dialog = new ItemDialog();      
                dialog.show(getFragmentManager(), "");
                getFragmentManager().executePendingTransactions();  

            }

            public static class ItemDialog extends DialogFragment
                {


                   @SuppressWarnings("deprecation")
                   @Override
                   public Dialog onCreateDialog(Bundle savedInstanceState) {
                      AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());        
                      builder.setView(getContentView());
                      Dialog dialog = builder.create();
                      dialog.setCanceledOnTouchOutside(true);
                      WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
                      lp.copyFrom(dialog.getWindow().getAttributes());
                      lp.width = WindowManager.LayoutParams.WRAP_CONTENT;
                      lp.height = WindowManager.LayoutParams.FILL_PARENT;
                      dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
                      dialog.getWindow().setAttributes(lp);   
                      return dialog;
                  }

            private View getContentView() {
                   LayoutInflater inflater = getActivity().getLayoutInflater();
                   View view = inflater.inflate(R.layout.popup_item, null);
                   return view;
            }
            }    

最佳答案

因此，经过大量搜索后，我还是找不到使用 API 5 使 DialogFragment 覆盖操作栏的方法。但是我找到了另一种方法来做到这一点，使 Fragment 在屏幕上调用一个新的 Activity ，主题为一个对话框。这个解决方案对我帮助很大，所以，我在这里分享它: https://stackoverflow.com/a/12275009/2327056

@StrikeForceZero using the idea from a google group post I was able to pull it off styling an activity. you would want to modify the height and width to a "dynamic" size of your choice preferably. Then set whatever ActionBar buttons you would like

<style name="PopupTheme" parent="android:Theme.Holo.Light.Dialog">
    <item name="android:windowIsFloating">false</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowSoftInputMode">stateAlwaysHidden</item>
    <item name="android:windowActionModeOverlay">true</item>
    <item name="android:windowIsTranslucent">true</item>
</style>

public static void showAsPopup(Activity activity) {
    //To show activity as dialog and dim the background, you need to declare android:theme="@style/PopupTheme" on for the chosen activity on the manifest
    activity.requestWindowFeature(Window.FEATURE_ACTION_BAR);
    activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND,
            WindowManager.LayoutParams.FLAG_DIM_BEHIND);
    LayoutParams params = activity.getWindow().getAttributes(); 
    params.height = 850; //fixed height
    params.width = 850; //fixed width
    params.alpha = 1.0f;
    params.dimAmount = 0.5f;
    activity.getWindow().setAttributes((android.view.WindowManager.LayoutParams) params); 
    setContentView(R.layout.activity_main);
}
