android - How to remove border in custom AlertDialog?

Question

I'm trying to create custom AlertDialog with an image text and buttons. When I display it I get a white border which looks horrible.

How can I get rid of that white border?

Here my custom Dialog:

public LinearLayout customeLL;
    public void  alertD()
    {
        AlertDialog ad;
        AlertDialog.Builder  builder;
        Context mContext = getApplicationContext();
        TextView a = new TextView(getApplicationContext());
        a.setText("Test dialog");
        ImageView img = new ImageView(getApplicationContext());
        img.setBackgroundResource(R.drawable.bottombar_bg);
        LinearLayout customeLL = new LinearLayout(getApplicationContext());
        customeLL.setOrientation(LinearLayout.VERTICAL);
        customeLL.addView(img,curWidth,37);
        customeLL.addView(a,curWidth,37);
        builder = new AlertDialog.Builder(myClass.this);
        builder.setView(customeLL);
        ad=builder.create();
        ad.show();

    }

As you can see the topborder and image have a space in 2-3 px.

try this use Dialog Instead of AlertDialog.Builder

.. for remove border line from Dialog..

Dialog dialog = new Dialog(this,android.R.style.Theme_Translucent_NoTitleBar);
