Setting width and height to AlertDialog with custom layout doesn't apply correctly

The text in my dialog is too long, and it mixes with buttons. So I figured out I should change the size of the dialog.
upd.: To make it clear, the question is if it's possible to change the size of the alert dialog in such way so that these changes apply to a layout, and how? If it is really impossible, why and what are the alternatives.
Here is how I am trying to do it in my code, according to answers in this topic:
int matchParent = WindowManager.LayoutParams.MATCH_PARENT;
rulesDialog.show();
rulesDialog.getWindow().setLayout(matchParent, matchParent);
And I got this, it just adds the white gap:
Also tried this. That didn't work at all.
I also tried to add this line with the same approach, did nothing:
<item name="android:layout_height">match_parent</item>
Here is xml code of a layout passed to the AlertDialog.Builder:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/beige">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:gravity="center"
android:padding="4dp"
android:layout_margin="4dp"
android:textColor="#color/brown"
android:textSize="14sp"
android:text="#string/info_text"
android:id="#+id/info_text"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/info_text"
android:layout_centerHorizontal="true"
android:text="#string/ok"
android:padding="4dp"
android:textSize="14sp"
android:textColor="#color/orange"
android:background="#color/blank"
android:minHeight="0dp"
android:minWidth="0dp"
android:layout_margin="4dp"
android:id="#+id/ok"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/info_text"
android:layout_toEndOf="#id/ok"
android:text="#string/renew_record"
android:padding="4dp"
android:textSize="14sp"
android:textColor="#color/orange"
android:background="#color/blank"
android:minWidth="0dp"
android:minHeight="0dp"
android:layout_margin="4dp"
android:id="#+id/renew_record"/>
</RelativeLayout>
upd.: I've found that this code works:
rulesDialog.show();
int matchParent = WindowManager.LayoutParams.MATCH_PARENT;
rulesDialog.getWindow().setLayout(matchParent, matchParent);
rulesDialog.setContentView(R.layout.info);
Solves the white gap problem totally.
For some case, the problem with overlapping still exists. As far as I understand, that's a common problem for RelativeLayout, now I am investigating it.
upd.: Yes, I should've deleted android:layout_centerVertical="true" line from the TextView. Now all works fine with two latter fixes, problem solved.

You can either use scroll view in your .xml or enable scrolling in textview itself. I think the later is more simple and as follows.
<TextView
android:id="#+id/info_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
....
android:maxLines="7" <-- play with this number to best suit your expectations-->
android:scrollbars="vertical"
/>
Finally in your .java/.kt file.
textView.setMovementMethod(new ScrollingMovementMethod());

Android ImageButton not enforcing transparency in RelativeLayout

I am trying to place two image buttons and some text on a single line. Here is the XML for the layout:
<?xml version="1.0" encoding="utf-8"?>
<mycompany xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="28dp"
android:layout_marginTop="5dp"
android:orientation="horizontal">
<ImageButton
android:id="#+id/sectionDelete"
android:layout_width="35dp"
android:layout_height="28dp"
android:layout_alignParentLeft="true"
android:src="#drawable/button_delete" />
<TextView
android:id="#+id/header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/sectionDelete"
android:text="test"
android:textAllCaps="true"
android:textColor="#color/navigation_bar"
android:textSize="16sp"
android:textStyle="bold" />
<ImageButton
android:id="#+id/sectionAdd"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:background="#drawable/button_add" />
</RelativeLayout>
<View
android:id="#+id/line"
android:layout_marginTop="8dp"
android:layout_width="match_parent"
android:layout_height="2dp"
android:background="#android:color/darker_gray" />
</LinearLayout>
</mycompany>
The selector XML for each of the buttons in drawable:
button_delete.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/delete_button_pressed"
android:state_pressed="true" />
<item android:drawable="#drawable/delete_button"
android:state_focused="true" />
<item android:drawable="#drawable/delete_button" />
</selector>
button_add.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/button_add_pressed"
android:state_pressed="true" />
<item android:drawable="#drawable/button_add_normal"
android:state_focused="true" />
<item android:drawable="#drawable/button_add_normal" />
</selector>
In the builder all looks well:
But in the application the gray background is lost and the edges of the image (which are transparent) are shown, but only for the first image:
Strangely, the first image button is not recognizing the transparent background of the image. Additionally I needed to mess with the width and height of the RelativeLayout and the first ImageButton to even get it close to the right size. With the 2nd I did not have to do anything. There is nothing special with the first image.
Here are the images from the directory:
One last issue - How do you make the text wrap before the 2nd image if it is too long for the space? Right now it writes under the 2nd image before wrapping:
Here are all the delete images. Seem to have transparent backgrounds, but I am far from a Gimp expert. Also not sure if StackOverflow keeps the original..
Update
I have verified the images are transparent. The image still has the white background. I have also updated the XML to look like this:
<?xml version="1.0" encoding="utf-8"?>
<mycompany xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:orientation="horizontal">
<ImageButton
android:id="#+id/sectionDelete"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:background="#drawable/button_delete" />
<TextView
android:id="#+id/header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/sectionDelete"
android:layout_toEndOf="#+id/sectionDelete"
android:layout_toLeftOf="#+id/sectionAdd"
android:text="test"
android:textAllCaps="true"
android:textColor="#color/navigation_bar"
android:textSize="16sp"
android:textStyle="bold" />
<ImageButton
android:id="#+id/sectionAdd"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:background="#drawable/button_add" />
</RelativeLayout>
<View
android:id="#+id/line"
android:layout_marginTop="8dp"
android:layout_width="match_parent"
android:layout_height="2dp"
android:background="#android:color/darker_gray" />
</LinearLayout>
</mycompany>

You should use:
<ImageButton
android:id="#+id/sectionDelete"
android:layout_width="35dp"
android:layout_height="28dp"
android:layout_alignParentLeft="true"
android:src="#drawable/button_delete"
android:background="#android:color/transparent"/>

Use "#null" like background on ImageButton:
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:srcCompat="#drawable/bkash"
android:id="#+id/bid1"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:background="#null" />

You haven't included the actual PNG file you are using as an icon for your delete button (screenshot from Windows's Explorer showing this file on your disk isn't quite enough), but I am almost sure that this file lacks an alpha channel. Instead, there is a white color on every pixel you'd like to be set with zero alpha channel value.
Opening your graphic in some image editor and changing these white pixels to transparent will solve your problem, but as for the reason why your layout "looks different" in builder than on your device, it's because there is a default theme applied by the system to every app, you can read more about it here: https://developer.android.com/guide/topics/ui/look-and-feel/themes.html
This default, OS and device specific set of values determines things that aren't determined by app's authors.
In the case of your device, its OS determined app's background color to be gray, which wasn't the case with your builder. Your builder chose the background to be white. Your delete button's graphic never was transparent, but on the white background of your builder it looked like it was.
To make it look like on builder, you need to specifically apply the background by yourself to the root of your view. In this case, it's a LinearLayout which should look like this:
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffffff">

1) #DimDim had the right solution, if it didn't work, the delete button may have white background in the image, cross check with a png viewer.
2) To prevent overflow of text, try this
<TextView
android:id="#+id/header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/sectionDelete"
android:layout_toLeftOf="#+id/sectionAdd"
android:text="test"
android:textAllCaps="true"
android:textColor="#color/navigation_bar"
android:textSize="16sp"
android:textStyle="bold" />
And put the sectionAdd Image button above this textview in the XML as this textview needs reference to the sectionAdd.

UI bug android - screen not matched on top edge

I'm working on this app and I have implemented a photo slider through ViewPager. There is an imported circle page slider indicator, a project on github. It looks like this: (Sorry for the blured text, I'm not able to share the content until release. The app will be free)
My problem is that thin blue line on the top of the screen. Blue color comes from the background and it is set in the root layout of the activity. No matter what I do to the any of the layouts (changing margins or padding to negative values) this line remains there.
So I figured that it has to do with the chosen theme for the screen. Theme is set to a custom theme which has Theme.NoTitleBar as it's parent. The code is below:
This is the style file. Taken from http://viewpagerindicator.com/ by Jake Wharton.
<style name="Theme.PageIndicatorDefaults" parent="android:Theme.NoTitleBar">
<!--<item name="vpiIconPageIndicatorStyle">#style/Widget.IconPageIndicator</item>
<item name="vpiTabPageIndicatorStyle">#style/Widget.TabPageIndicator</item>-->
<item name="vpiCirclePageIndicatorStyle">#style/Widget.CirclePageIndicator</item>
</style>
This is my activity layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/accountRoot"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/gradientbg"
android:orientation="vertical"
android:gravity="bottom">
<RelativeLayout
android:id="#+id/titleBar"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:visibility="visible"
>
<android.support.v4.view.ViewPager
android:id="#+id/viewPagerSlider"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:overScrollMode="never"
/>
<io.colomb.android.colombio.customviews.CirclePageIndicator

android:layout_centerHorizontal="true"
android:layout_alignBottom="#id/viewPagerSlider"
android:layout_marginBottom="20dp"
android:paddingRight="5dp"
android:paddingLeft="5dp"
/>
</RelativeLayout>
<ImageView
android:id="#+id/ivSoftboardLogo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/logosoftboard"

android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_weight="0.001"
android:layout_marginTop="-15dp"

</LinearLayout>
Any thoughts are appreciated.

OK solved. The thing that was bothering the adapter was the line gravity="bottom"in the root element. Also the pictures needed to be cropped more

Android: how to make two TextViews placed in different lines if there is not enough space in one line

I'm trying to organize two TextViews to behave like that:
So, if there is enough space for both TextViews in line, android should place them in line.
If there is not enough space, the second TextView must be placed on the next line with right alignment.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/takeoffCity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="#style/flightItem" />
<TextView
android:id="#+id/landingCity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="#style/flightItem" />
</LinearLayout>
<style name="flightItem" parent="#android:style/TextAppearance">
<item name="android:textSize">14dip</item>
<item name="android:textColor">#color/flightItemFont</item>
<item name="android:scrollHorizontally">true</item>
<item name="android:textStyle">bold</item>
</style>

To accomplish what you are looking for you could change you're layout to a RelativeLayout and add android:layout_alignParentLeft="true" to your TextViews, however, this doesn't set these TextViews to act dynamically. Meaning if they can fit side-by-side then they should be in-line but the bottom TextView will still align to the right.
I don't think what you are looking for is technically possible. However this may be a good alternative:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/takeoffCity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
style="#style/flightItem" />
<TextView
android:id="#+id/landingCity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
style="#style/flightItem" />
</RelativeLayout>

How to remove button background color

I searched a lot but I didn't find how to remove the background color from the button which is appearing on the right and left side of button. Can anybody help?

this is the image used with name change.9.png

according to your scenario i can surely say that either you are not using a 9-patch image (an image with extension like .9.png ) or the 1 pixel borders of 9-patch at left and top are not drawn in correct manner. thats why the edges and the side border shade get expanded with the button with long width. either you should show what 9-patch button background you have used or try some correct 9-patch and check results for that.

Why don't you use some other control element like TextView instead of buttons? I just saw that TextView has onClickListner and so you can use it as sort-of button, though I have not done it; button is meant to aid you defining your layout, but as this seems to only be a problem for you, just do not use it).
By the way I seriously recommend you to use android styles, as you copy-paste a lot of attributes. If you use Eclipse for development, open your layout xml, select the item you want to extract the style of, press ctrl + 1 and then select extract style. That way you should avoid copy-pasting all these style attributes.

Try removing the android:textColor attribute. These can be misleading and sometimes alter the colour of more than just the text. If the text is supposed to be black then you don't need it.
