Android bypassing theme setting - android

I have a Layout with a TextView in an application - not written by me. I want to set it to bold or change the font family in the xml. In the application written by me it works correctly. But in this one, the change doesn't show. I suppose that's because a theme was applied. If I change the setting programmatically it works and if I set it to bold programmatically it works.
myTextView.Typeface(Typeface.DEFAULT_BOLD).
How can I overwrite the theme setting?
UPDATE:
The Layout that i have is this:
<LinearLayout
android:id="#+id/lFiltro"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10sp"
android:layout_marginEnd="10sp"
android:orientation="horizontal"
android:visibility="gone">
<TextView
android:id="#+id/tUno"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:fontFamily="#font/archivo_black"
android:shadowColor="#33b5e5"
android:shadowDx="4"
android:shadowDy="4"
android:shadowRadius="5"
android:text="This is my text"
android:textAlignment="center"
android:textColor="#0000ff"
android:textSize="24sp"
android:textStyle="bold"
android:visibility="visible" />
</LinearLayout>


Try to add
android:textAppearance="#style/TextAppearance.AppCompat.Subhead"
to your TextView xml and change what is after TextAppearance. according to the suggestions you will get.

Remove underline from TextView which uses Widget.EditText style

I have a TextView for showing user's wallet balance in my app. In order to set error indicator on low balance I added Widget.EditText style to the TextView. My issues is after adding this style, the TextView is showing an under line. How can I remove that underline?
My TextView
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/hm_bal"
android:textColor="#color/primary_dark"
android:textSize="14sp"
android:textStyle="bold"
android:layout_gravity="left"
android:padding="3dp"
android:gravity="top"
android:text="----"
style="#android:style/Widget.EditText" />
I don't want to change the style since using this theme was perfect for my requirement except the underline.

Try to set transparent background in your textview
android:background="#android:color/transparent"
LIKE
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/hm_bal"
android:textColor="#color/colorPrimaryDark"
android:textSize="14sp"
android:textStyle="bold"
android:layout_gravity="left"
android:padding="3dp"
android:gravity="top"
android:text="----"
android:background="#android:color/transparent"
style="#android:style/Widget.EditText" />

set background null
android:background="#null"

How to make TextView in Android wrap and adjust text beautifully?

When text is small then I get this:
But when text is big I get this:
Is it possible that text adjust itself by maybe better using spaces or decreasing little size automatically?
This is my TextView xml:
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/seaGreen"
android:gravity="center_vertical"
android:padding="10dp"
android:textColor="#color/white"
android:textSize="35sp" />

For that you need to use external library for that, else you can set gravity as center

this work for me:
<TextView
android:id="#+id/your_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:textAlignment="center"
android:gravity="center"
android:padding="5dp"
android:text=""
android:textSize="14sp"/>

How do you remove the extra inner padding inside a Spinner button in an Android layout?

I am trying to create a Button that looks like a Spinner.
I have done this by creating a Button like this:
<Button
android:id="#+id/dateButton"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/dateLabel"
android:text="default text"
android:textSize="15sp"
style="?android:attr/spinnerStyle"
android:gravity="center_vertical|center_horizontal" />
The problem is that the text ("default text") inside the Button seems to have extra padding around it, which makes the Button look bloated and expanded in its height.
I thought that setting the layout_height for the button to "wrap_content" would fix this and make the button thinner, but it does not have any effect.
Does anyone know how to make this button's height wrap to the text inside it?
Here is the example code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_marginLeft="10dp" >
<TextView
android:id="#+id/dateLabel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="25dp"
android:text="Select date:"
android:textSize="15sp" />
<Button
android:id="#+id/dateButton"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/dateLabel"
android:text="default text"
android:textSize="15sp"
style="?android:attr/spinnerStyle"
android:gravity="center_vertical|center_horizontal" />
</RelativeLayout>

android:gravity="center_vertical|center_horizontal" instead of this you can write
android:gravity="center" but as per your requirment just remove this line.do not add any gravity and change your height size android:layout_height="40dp"
i changed your code
<Button
android:id="#+id/dateButton"
android:layout_width="150dp"
android:layout_height="35dp"
android:layout_toRightOf="#+id/dateLabel"
android:text="default text"
style="?android:attr/spinnerStyle"
/>

The padding of this button is decided by the drawable of it. You either need to change the spinner drawable (can be done at runtime) , or provide your own drawable to the given button that would make it look like a spinner, without using the default one

Android button with icon and text

I have some buttons like this in my app:
<Button
android:id="#+id/bSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="16dp"
android:text="Search"
android:textSize="24sp" />
I'm trying to create a same button with text and a icon.
android:drawableLeft doesn't work for me (Maybe it would, but i don't know how to set a max height to the icon).
So i created a LinearLayout with a ImageView and a TextView and made it act like a button:
<LinearLayout
android:id="#+id/bSearch2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:drawable/btn_default"
android:clickable="true"
android:padding="16dp"
android:orientation="horizontal" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="5dp"
android:adjustViewBounds="true"
android:maxHeight="30dp"
android:maxWidth="30dp"
android:scaleType="fitCenter"
android:src="#drawable/search_icon" />
<TextView
android:id="#+id/tvSearchCaption"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:textSize="24sp"
android:paddingRight="30dp"
android:gravity="center"
android:text="Search" />
</LinearLayout>
My new button is exactly what i want (font size, icon and text placement).
But it doesn't look like my default buttons:
So i tried, to change the background and the text color of my new Button:
Button Search = (Button) findViewById(R.id.bSearch);
LinearLayout bSearch2 = (LinearLayout) findViewById(R.id.bSearch2);
bSearch2.setBackground(bSearch.getBackground());
TextView tvSearchCaption = (TextView)findViewById(R.id.tvSearchCaption);
tvSearchCaption.setTextColor(bSearch.getTextColors().getDefaultColor());
This gives a strange result, my old button, gets messed up:
When i change the order of these two buttons in the XML, so the "new button" goes first, it makes another strange result:
Now i noticed, that when i try to press the old button, the new one gets pressed.
Any ideas?

Try this one.
<Button
android:id="#+id/bSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="16dp"
android:text="Search"
android:drawableLeft="#android:drawable/ic_menu_search"
android:textSize="24sp"/>

To add an image to left, right, top or bottom, you can use attributes like this:
android:drawableLeft
android:drawableRight
android:drawableTop
android:drawableBottom
The sample code is given above. You can also achieve this using relative layout.

You can use the Material Components Library and the MaterialButton component.
Use the app:icon and app:iconGravity="start" attributes.
Something like:
<com.google.android.material.button.MaterialButton
style="#style/Widget.MaterialComponents.Button.Icon"
app:icon="#drawable/..."
app:iconGravity="start"
../>

For anyone looking to do this dynamically then setCompoundDrawablesWithIntrinsicBounds(Drawable left, Drawable top, Drawable right, Drawable bottom) on the buttons object will assist.
Sample
Button search = (Button) findViewById(R.id.yoursearchbutton);
search.setCompoundDrawablesWithIntrinsicBounds('your_drawable',null,null,null);

This is what you really want.
<Button
android:id="#+id/settings"
android:layout_width="190dp"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:background="#color/colorAccent"
android:drawableStart="#drawable/ic_settings_black_24dp"
android:paddingStart="40dp"
android:paddingEnd="40dp"
android:text="settings"
android:textColor="#FFF" />

#Liem Vo's answer is correct if you are using android.widget.Button without any overriding. If you are overriding your theme using MaterialComponents, this will not solve the issue.
So if you are
Using com.google.android.material.button.MaterialButton
or
Overriding AppTheme using MaterialComponents
Use app:icon parameter.
<Button
android:id="#+id/bSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="16dp"
android:text="Search"
android:textSize="24sp"
app:icon="#android:drawable/ic_menu_search" />

What about like this?
<Button
android:id="#+id/yourID"
android:drawableStart="#drawable/ic_flag"
android:textColor="#FFFFFF"
android:textSize="12sp"
android:textStyle="bold"
android:textAlignment="textStart"
android:background="#drawable/btn_background"
android:fontFamily="#font/YourFont"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Your Text" />

try It:-
position-> left,right,top,bottom
android:drawableposition="#android:drawable/-yourImage-"
android:drawabletop="-Yourfilesrc-"
android:drawablebottom="-Yourfilesrc-"
android:drawableleft="-Yourfilesrc-"
android:drawableright="-Yourfilesrc-"

I was experiencing the same problem with pure Button view. In my case XML solution was not usefull, because I have some logic to show/hide this icon.
There is one more solution using pure Kotlin:
(bSearch as? MaterialButton)?.let {
icon = AppCompatResources.getDrawable(context, R.drawable.search_icon)
iconGravity = MaterialButton.ICON_GRAVITY_START
}
P.S. We can cast Button to MaterialButton as fair as we can use icon param in Button: icon param is not actually Button param - it is sneaky MaterialButton param somehow working with Buttons.

Android Textview Italic and wrap_contents

I am using 3 italic textviews with different colors
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:orientation="horizontal" android:id="#+id/submittedBy" android:paddingTop="10dip">
<ImageView android:id="#+id/subByImg"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:gravity="left" android:layout_gravity="bottom" android:src="#drawable/submitted_by_arrow"/>
<TextView android:id="#+id/submitLabel"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:gravity="left" android:text="Submitted by" android:textStyle="italic"
android:textSize="12sp" android:textColor="#color/gray" android:paddingLeft="5dip"/>
<TextView android:id="#+id/submitName" android:textStyle="italic"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:textSize="12sp" android:textColor="#color/maroon_dark" android:paddingLeft="10dip"/>
<TextView android:id="#+id/submitByDate" android:textStyle="italic"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:gravity="left"
android:textSize="12sp" android:textColor="#color/gray" android:paddingLeft="10dip"/>
</LinearLayout>
I wonder every last character is not displaying properly specially name displayed in the middle is "Dan Buckland" and it it is missing last character looks like "Dan Bucklano"
Also tell me pls how can have textview italic and bold both..
alt text http://www.freeimagehosting.net/uploads/953d573113.jpg

I had the exact same problem. I got around it by simply adding a space to the end of any string that needs to be in italics.
It may not be the most long-term-correct solution but it worked for me.

Seems like the bounding box is not correctly calculated when using italic.
Have you tried to use paddingLeft=6 and paddingRight=6 for the elements?
(less chance of overlap).
For multiple styles in a TextView see Is it possible to have multiple styles inside a TextView?

You can use   with the text in string.xml file.
