For using action bar in Dialog, you have to create a custom theme in your style.xml with parent as "Theme.AppCompat.Light".

And add this style in your manifest with activity tag:

and last add this code in your activity before setConytentView(layoutID);

@Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_ACTION_BAR);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND,
            WindowManager.LayoutParams.FLAG_DIM_BEHIND);
        LayoutParams params = this.getWindow().getAttributes(); 
        params.alpha = 1.0f;
        params.dimAmount = 0.5f;
        this.getWindow().setAttributes((android.view.WindowManager.LayoutParams) params); 

        // This sets the window size, while working around the IllegalStateException thrown by ActionBarView
        this.getWindow().setLayout(600,900);

        setContentView(R.layout.dialog_move);
}
