Android Dialog: Removing title bar

I have a weird behavior I can't pinpoint the source of.

I have my app with the classic

requestWindowFeature(Window.FEATURE_NO_TITLE);

to remove the title/status bar.

I then create a Dialog box to allow the user to enter information (name etc)

With a physical keyboard, no problem but when I use the virtual keyboard I have a strange behavior:

each time I hit a key on the virtual key board the title/status bar reappears pushing all the keyboard layout around then vanishes again (just like the animation of when I start the application)

here is some code :

        dialog = new Dialog(context);
        dialog.setContentView(R.layout.logindialog);
        dialog.setTitle("Login:");

        WindowManager.LayoutParams a = dialog.getWindow().getAttributes();

//      dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

        a.dimAmount = 0;
        dialog.getWindow().setAttributes(a);

        dialog.setCancelable(true);
        dialog.getWindow().setLayout(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT);

and then

dialog.show();

I tried

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

but it crashes my app.

here is the xml

    <TextView android:id="@+id/LoginText"
        android:gravity="fill"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Login:">
    </TextView>         
    <EditText android:id="@+id/LoginEdit"
        android:layout_height="wrap_content"
        android:singleLine="true"
        android:text="jason"
        android:layout_width="200sp"/>
    <TextView android:id="@+id/PasswordText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Password:">
    </TextView>         
    <EditText android:id="@+id/PasswordEdit"
        android:layout_height="wrap_content"
        android:singleLine="true"
        android:text="welcome"
        android:layout_width="200sp"
        android:password="true"/>
<LinearLayout 
    android:id="@+id/test2"
    android:gravity="center_horizontal"
    android:orientation="horizontal"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
<Button android:id="@+id/LoginButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:text="Login" />
<Button android:id="@+id/CreateButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:text="Create" />
<Button android:id="@+id/CancelLogin"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:text="Cancel" />
</LinearLayout>/>

use,

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); //before     
dialog.setContentView(R.layout.logindialog);

create new style in styles.xml

<style name="myDialog" parent="android:style/Theme.Dialog">
   <item name="android:windowNoTitle">true</item>
</style>

then add this to your manifest:

 <activity android:name=".youractivity" android:theme="@style/myDialog"></activity>

All the above answer not working for me for AppCompatDialog

If you are using AppCompatDialog try this

Important note: Set this before calling setContentView.

dialog.supportRequestWindowFeature(Window.FEATURE_NO_TITLE);

create your XML which is shown in dialog here it is activity_no_title_dialog

final Dialog dialog1 = new Dialog(context);
dialog1.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog1.setContentView(R.layout.activity_no_title_dialog);
dialog1.show();

With next variant I have no reaction:

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); //before     
dialog.setContentView(R.layout.logindialog);

So, I try to use next:

dialog.supportRequestWindowFeature(Window.FEATURE_NO_TITLE); //before     
dialog.setContentView(R.layout.logindialog);

This variant work excellent.
