Use a custom style for your AlertDialog.

Add the following style to your style.xml.

<style name="MyCustomTheme" parent="Theme.AppCompat.Light.Dialog.Alert">>
        <item name="android:layout_width">fill_parent</item>
        <item name="android:layout_height">fill_parent</item>
        <item name="android:windowBackground">@null</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">false</item>     
</style>

Set the theme to your AlertDialog in the activity:

final AlertDialog.Builder builder =
            new AlertDialog.Builder(this, R.style.MyCustomTheme);

There are server ways:-

Alert Dialog

AlertDialog.Builder builder;
     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
         builder = new AlertDialog.Builder(activityContext, android.R.style.Theme_Material_Light_Dialog_NoActionBar); // To remove extra space
     } else {
         builder = new AlertDialog.Builder(activityContext);
     }

builder.setTitle(dialogTitle);
builder.setButton(AlertDialog.BUTTON_NEUTRAL, "OK", new DialogInterface.OnClickListener() {
       @Override
       public void onClick(DialogInterface dialog, int which) {
            dialog.dismiss(); // Close dialog
       }
    });
builder.setCancelable(false); //to make Dialog's outside non-touchable
builder.show(); // to show dialog

Custom Dialog

Make Custom Design in style.xml file and you can add more values according to your requirement.

<style name="CustomDesign" parent="Theme.AppCompat.Light.Dialog.Alert">>
      <item name="android:layout_width">wrap_content</item>
      <item name="android:layout_height">wrap_content</item>
      <item name="android:windowBackground">@null</item>
      <item name="android:windowNoTitle">true</item>
</style>

Give this style to Alert Dialog or any dialog.

For Alert Dialog :-

AlertDialog.Builder builder =
    new AlertDialog.Builder(this, R.style.CustomDesign);

For Dialog :-

Dialog customDialog= new Dialog(this,R.style.CustomDesign);

Dialog

Dialog dialog = new Dialog(context);
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE); // To remove extra space
dialog.setContentView(R.layout.layout); // to set custom layout
dialog.show();
