I'm developing a Dialog, which should shrink to its content, so, I want to get a behaviour like wrap_content in a common view but for a normal Dialog. That's what I want to show in a Dialog Window

Layout

In a Dialog Window should look like this Desired behaviour

but this is what I actually get got behaviour

Could you say me what I do wrong?

I thank you in Advance.

That's my code

...
final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
dialog.setContentView(R.layout.advanced_options);
dialog.setTitle(titleId);

// Stuff referred to builder
AlertDialog.Builder builder ...
...

int type = WindowManager.LayoutParams.TYPE_INPUT_METHOD;
WindowManager.LayoutParams w_layout_params = new WindowManager.LayoutParams(type);

dialog.getWindow().setAttributes(w_layout_params );
...
builder.create();
dialog.show();

advanced_options.xml Layout

Change RelativeView's width to match_parent

What you're looking for is match_parent's behavior.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/relLayout_advancedOptions"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="@drawable/border_advanced_options"
android:divider="?android:listSeparatorTextViewStyle"
android:showDividers="" >

Note: wrap_content in android specifies the view to use as little space as needed and that is the behavior you're getting.

  • No, I think, you're confused, I want, that the Dialog Window, the parent, takes the dimension of its content, = child, the advanced_options.xml layout.Please, take a look at pics. Regards – Gödel77 Sep 16 '14 at 19:53
  • What I've suggested will remove the gap by expanding the content to the dialog. I understand that what you want is to decrease the size of the dialog. This didn't work? – Dheeraj Bhaskar Sep 16 '14 at 19:56
  • Dheeraj, I can do "match_parent" but what I want is that the Window takes the dimensions of my Layout and not contrary. I know, I must perform the `WindowManager.LayoutParams` of the Dialog but it doesn't work. By the way, I have forgotten to write `w_layout_params.width = WindowManager.LayoutParams.WRAP_CONTENT` and `w_layout_params.height= WindowManager.LayoutParams.WRAP_CONTENT`in my first Post but I have tried with them and it also didn't work. – Gödel77 Sep 16 '14 at 20:04

I could adjust the Dialog (NOT AlertDialog!) to my custom Layout but I couldn't* set either the Title or the Buttons so that I got an Exception cause of setting content before requestFeature, then I decided to custom my Dialog and including the Buttons and title in my Custom Layout.

*I have researched and it's possible to overcome that if we define the Dialog in OnCreate other even in OnCreateDialog but I have an extra Class just for static Dialog Methods and was no solution for me.

In Addition I post what it was useful for me, perhaps someone is also useful.

Now my custom dialog looks like this

enter image description here

Here the code for whom wants to test it.

/**
 * @param c
 *            the Context
 * @return the about dialog
 */
public static void getAdvancedOptions(final Activity activity) {

    Log.i("TAG", "Dialogs::getAdvancedOptions:: 0");
    //settings            = session.getSettings();

    // Creation of a Dialog with Frame and title Characteristics
    final Dialog dialog = new Dialog(activity);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.advanced_options_expanded);


    // Here we control the validity of "edit_text" Fields
    speed_limit_alert   = (EditText)dialog.findViewById(R.id.speed_limit_alert_edit_text);                                          
    minimum_speed       = (EditText)dialog.findViewById(R.id.minimum_speed_edit_text);                
    maximum_speed       = (EditText)dialog.findViewById(R.id.maximum_speed_edit_text);               
    max_objects_in_view = (EditText)dialog.findViewById(R.id.maximum_number_objects_edit_text);

    //showAdvancedOptions("getAdvancedOptions 1::");

    // First we set the "SharedPreferences"-saved values on EditText Fields                
    performEditText(speed_limit_alert,Constants.MIN_PERCENTAGE, Constants.MAX_PERCENTAGE,"speed_limit_alert"); 
    performEditText(minimum_speed, "","", "minimum_speed"); 
    performEditText(maximum_speed, "","","maximum_speed"); 
    performEditText(max_objects_in_view, "","","max_objects_in_view");  

    //showAdvancedOptions("getAdvancedOptions 4::");

    ok_button     = (Button)dialog.findViewById(R.id.ok_button);                                        
    cancel_button = (Button)dialog.findViewById(R.id.cancel_button);
