Ich kann keine Aktivität als Dialog in Android öffnen

Question

Ich entwickle eine Android App. In meiner App muss ich die Aktivität als Dialog starten. Ich habe einen Weg gefunden, dies zu tun, indem ich das Dialogthema im Manifest einstelle. Aber wenn ich die Aktivität starte, gibt es mir einen Fehler. Bitte sehen Sie mein Szenario unten.

Dies ist, wie ich in einem offenkundigen

konfigurieren

 <activity android:name=".ReplyActivity" 
      android:label="Reply" 
      android:theme="@android:style/Theme.Holo.Dialog"> 
      <action android:name="com.blog.waiyanhein.mmfashion.SettingsActivity"/> 
      <category android:name="android.intent.category.DEFAULT"/> 
     </activity> 

Dies ist, wie ich Aktivität in Adapter

private void openReplyActivity(int position) 
    { 
     Intent intent = new Intent(context, ReplyActivity.class); 
     intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
     intent.putExtra(ReplyActivity.NOTI_ID_FIELD,values.get(position).getId()); 
     intent.putExtra(ReplyActivity.REPLY_TO_FIELD,values.get(position).getUsername()); 
     context.startActivity(intent); 
    } 

Dies ist xml-Layout für Dialog Aktivität starten

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <LinearLayout 
     android:orientation="horizontal" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"> 
     <TextView 
      android:id="@+id/reply_tv_to_title" 
      android:text="Reply to" 
      android:textStyle="bold" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" /> 
     <TextView 
      android:id="@+id/reply_tv_reply_to" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" /> 
    </LinearLayout> 
    <RelativeLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"> 
     <EditText 
      android:id="@+id/reply_tf_message" 
      android:layout_width="match_parent" 
      android:layout_height="120dp" /> 
     <android.support.v7.widget.AppCompatButton 
      android:layout_below="@+id/reply_tf_message" 
      android:layout_alignParentRight="true" 
      android:layout_alignParentBottom="true" 
      android:background="@color/colorAccent" 
      android:textColor="@color/white" 
      android:text="Reply" 
      android:id="@+id/reply_btn_send" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" /> 
    </RelativeLayout> 
</LinearLayout> 

Dies ist der Fehler, den ich
