If you need an overarching dialog for all your fragments, just use the normal <a href="http://developer.android.com/guide/topics/ui/dialogs.html" rel="nofollow">dialog code</a> for activities with the fragment activity. Otherwise, just implement it in a DialogFragment as a child of the Fragment Activity.

blocks|key|1855061|text|我遇到了同样的问题。我知道你在一年前提出了这个要求，但仍然是为了帮助其他用户。这就是我解决问题的方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1855062|public+void+show_dialog()+{
++++FragmentManager+fm+=+getFragmentManager();
++++DialogFragment+newFragment+=+new+DialogFragment();
++++newFragment.show(fm,+"abc");
}|code-block|syntax|javascript|1855063|这只需要FragmentManager导入，而不需要FragmentActivity。|1855064|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

I encountered the same problem. I know you asked this a year ago, but still to help other users. This is how I resolved the problem.

<pre><code>public void show_dialog() {
 FragmentManager fm = getFragmentManager();
 DialogFragment newFragment = new DialogFragment();
 newFragment.show(fm, "abc");
}
</code></pre>

This just requires the FragmentManager import, not the FragmentActivity.

Maybe a little bit late but I also had the problem to call a DialogFragment from a non FragmentActivity. Also making it a FragmentActivity just for a simple dialog would not make sense. So the solution for me was to make a interface with a callback void to get the DialogFragment response in the activity. For me it is bether to get the response near the dialog call rather than geting it somewhere in a onActivityResult override. 

The interface:

<pre><code> import android.os.Parcelable;

/**
 * Created by TH on 03.11.2015.
 */
public interface OnDialogResponseListener extends Parcelable {

 void onDialogResponse(int responseCode);

}
</code></pre>

The generic dialog class:

<pre><code>import android.app.Activity;
import android.app.Dialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.support.v7.app.AlertDialog;

/**
 * Code basisc found here:
 * http://stackoverflow.com/questions/7977392/android-dialogfragment-vs-dialog
* changed by TH on 03.11.2015.
 */
public class YesNoDialog extends DialogFragment
{

 public static final String TITLE="title";
 public static final String MESSAGE="message";
 public static final String LISTENER="listener";
 public static final String YES="yes";
 public static final String NO="no";
 public static final String ICON_ID="icon_id";
 private OnDialogResponseListener mResponseListener;

 public YesNoDialog()
 {

 }


 @Override
 public Dialog onCreateDialog(Bundle savedInstanceState)
 {
 Bundle args = getArguments();
 String title = args.getString(TITLE, "");
 String message = args.getString(MESSAGE, "");
 String yes = args.getString(YES, "");
 String no = args.getString(NO, "");
 int iconID=args.getInt(ICON_ID);
 mResponseListener=args.getParcelable(LISTENER);

 return new AlertDialog.Builder(getActivity())
 .setTitle(title)
 .setMessage(message)
 .setIcon(iconID)
 .setPositiveButton(yes, new DialogInterface.OnClickListener() {
 @Override
 public void onClick(DialogInterface dialog, int which) {
 if (mResponseListener != null) {
 mResponseListener.onDialogResponse(Activity.RESULT_OK);
 }

 }
 })
 .setNegativeButton(no, new DialogInterface.OnClickListener() {
 @Override
 public void onClick(DialogInterface dialog, int which) {
 if (mResponseListener != null) {
 mResponseListener.onDialogResponse(Activity.RESULT_CANCELED);
 }
 }
 })
 .create();
 }
}
</code></pre>

And the usage would be like this:

<pre><code>OnDialogResponseListener onDialogResponseListener=new OnDialogResponseListener() {


 @Override
 public int describeContents() {
 return 0; //Leave this as it is
 }

 @Override
 public void writeToParcel(Parcel dest, int flags) {
 //Leave this as it is
 }

 @Override
 public void onDialogResponse(int responseCode) {


 //Do what you want with your dialog answers

 if(responseCode== Activity.RESULT_OK){
 Toast.makeText(MovementActivity.this,"OK pressed",Toast.LENGTH_LONG).show();
 }else if(responseCode==Activity.RESULT_CANCELED){
 Toast.makeText(MovementActivity.this,"CANCEL pressed",Toast.LENGTH_LONG).show();
 }

 }
 };


 YesNoDialog dialog = new YesNoDialog();
 Bundle args = new Bundle();
 args.putInt(YesNoDialog.ICON_ID, R.drawable.ic_action_add_light);
 args.putString(YesNoDialog.YES, getString(R.string.action_add));
 args.putString(YesNoDialog.NO, getString(R.string.action_cancel));
 args.putString(YesNoDialog.TITLE, getString(R.string.dialog_title_add_item));
 args.putString(YesNoDialog.MESSAGE, getString(R.string.dialog_message_add_item));
 args.putParcelable(YesNoDialog.LISTENER, onDialogResponseListener);
 dialog.setArguments(args);
 dialog.show(getSupportFragmentManager(), "tag");
</code></pre>

That is all. Maybe a little bit more code than in a simle Dialog but it keeps its values and shows on orientation change. That was my goal for using a DialogFragment.

Very very simple, just use getSupportFragmentManager()

dialogConfirmRequest.setCancelable(true);
dialogConfirmRequest.show(getSupportFragmentManager() ,&quot;meudialog&quot;);

Is it possible to use a <code>DialogFragment</code> when using an <code>Activity</code> instead of a <code>FragmentActivity</code>? The <code>show()</code> methods needs a <code>FragmentManager</code>.

I want to implement a Dialog which contains just one <code>EditText</code>, and the tutorials on android developers says I have to use a custom layout on a dialog fragment. So I asked cause I don't feel like changing to use <code>FragmentActivity</code> just for 1 dialog.

SOLVED:
I decided just to use <code>FragmentActivity</code> instead of <code>Activity</code> so it won't get more complicated.
