Change color selector/text new Text MaterialButton

I need to customize the text color or background color of the selector when button is selected, because the color of the text its too similar and the text disappears
This is my code:
<android.support.design.button.MaterialButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
style="#style/Widget.MaterialComponents.Button.TextButton"
android:text="#string/lbl_forgotten_password"
android:textColor="#color/gray_text_1"
android:textSize="14sp" />
This is how it looks:

You can solve this problem by using selector.
Create a new xml file into the drawable folder.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true" android:color="#color/text_color" android:drawable="#drawable/button_bg"/>
<item android:color="#color/text_normal" />
</selector>
After
<android.support.design.button.MaterialButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:background="#drawable/your_xml_file_name"
android:text="#string/lbl_forgotten_password"
android:textSize="14sp" />

DrawableLeft in center with text

I can't center my drawableLeft icon.
I can easily put icon on the left of text, but if I set gravity to center, then only text is centered, but no icon.
<Button
android:id="#+id/patient_list_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/patientList"
android:drawableLeft="#drawable/ic_icon_two_heads"
android:layout_marginBottom="15dp"
style="#style/darkBlueButtonWithImage"/>
This is what I want:
This is what I have:
<style name="darkBlueButtonWithImage">
<item name="android:drawablePadding">10dp</item>
<item name="android:textColor">#color/white</item>
<item name="android:paddingLeft">10dp</item>
<item name="android:background">#drawable/radius_dark_blue_button</item>
<item name="android:gravity">center_vertical|left</item>
<item name="android:drawableTint">#color/white</item> <!-- has to be set in activity.java -->
</style>
How can I achieve this?

Finally, after all these years, we have possibility to achieve such behavior in simple and intuitive way.
All you have to do is use MaterialButton from Google Material library. Then use style with icon. After that you can use app:iconGravity property and set it to textStart
<com.google.android.material.button.MaterialButton
style="#style/Widget.MaterialComponents.Button.Icon"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Some text"
app:iconGravity="textStart"
app:icon="#drawable/some_icon" />

The easiest solution IMO:
yourButtonView.text = SpannableString(" ${getString(R.string.your_string)}").apply {
setSpan(
ImageSpan(requireContext(), R.drawable.your_icon),
0,
1,
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
)
}
Is a bit hacky? Maybe. Does it work with every button (MaterialButton, AppCompatButton, Button, etc)? It does.
I prefer this rather than going with all the hassle of creating a custom view or something like that.

After giving Google's approach a try over 9000 times, I almost always ended up using a ViewGroup to put both side by side, particularly a RelativeLayout or LinearLayout and then adding an ImageView and a TextView. It's lame, but drawableStart/End have so many missing features that you'll waste a lot of time before you realize "you can't do it".
Alignments, tinting, Vectors, etc. All those things are harder or impossible with the "built in" drawable.

Using Button attributes android:drawableLeft and android:drawablePadding you won't be able to get your expected result. You can create a custom button using RelativeLayout or LinearLayout, TextView and ImageView. Use <selector> to define your button state(normal/pressed) behavior.
Here is an working example. Try this:
<!--- Custom Button -->
<RelativeLayout
android:id="#+id/patient_list_button"
android:layout_width="match_parent"
android:layout_height="48dp"
android:clickable="true"
android:background="#drawable/custom_button_selector">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_centerInParent="true"
android:gravity="center_vertical">
<ImageView
android:layout_width="24dp"
android:layout_height="24dp"
android:src="#drawable/icon_refresh"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:textSize="16dp"
android:text="CUSTOM BUTTON"
android:textStyle="bold"
android:textColor="#FFFFFF"/>
</LinearLayout>
</RelativeLayout>
custom_button_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_pressed="true"
android:state_enabled="true"
android:drawable="#drawable/bg_custom_button_pressed" />
<item
android:state_focused="true"
android:state_enabled="true"
android:drawable="#drawable/bg_custom_button_pressed" />
<item
android:state_enabled="true"
android:drawable="#drawable/bg_custom_button_normal" />
</selector>
bg_custom_button_normal.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<!-- view background color -->
<solid
android:color="#01A1DD" >
</solid>
<!-- Here is the corner radius -->
<corners android:radius="8dp" >
</corners>
</shape>
bg_custom_button_pressed.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<!-- view background color -->
<solid
android:color="#303F9F">
</solid>
<!-- Here is the corner radius -->
<corners android:radius="8dp" >
</corners>
</shape>
OUTPUT:
Hope this will help~

a) Increase "paddingLeft" value and shrink or remove "drawablePadding" in your case, adjust the value to a proper one; for example:
android:paddingLeft="50dp"
android:gravity="center_vertical|left"
b) Use a custom view.

A bit hacky solution:
<TextView
android:id="#+id/tv_whatsapp"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toLeftOf="#id/tv_call"
app:layout_constraintTop_toBottomOf="#id/tv_completed_message_desc"
android:layout_width="0dp"
android:layout_height="40dp"
android:textStyle="normal"
android:layout_marginTop="#dimen/rs_dp_13"
android:layout_marginRight="#dimen/rs_dp_12"
android:background="#drawable/rs_dark_teal_rectangle_bg"
android:textSize="14sp"
android:textColor="#color/dark_teal"
**android:paddingHorizontal="38dp"**
android:includeFontPadding="false"
**android:drawableStart="#drawable/rs_user_journey_whatsapp_icon"**
**android:drawableLeft="#drawable/rs_user_journey_whatsapp_icon"**
android:visibility="visible"
android:letterSpacing="0.04"
app:layout_constraintHorizontal_chainStyle="packed"
**android:gravity="center_vertical|end"**
android:text="Whatsapp"/>
Setting horizontal padding along with gravity as center_vertical|end will achieve the required behaviour. You can increase/decrease the padding as per requirement.

How to change bottom line color of an edit text?

I have a dialog layout in that i have 3 edit texts, for the 1st edit text it shows the underline color as green(primary color), and other two edit text shows the color pink(color accent).
Why so? It should be same as other two edit texts.
Tried to change this with :
name.getBackground().mutate().setColorFilter(getResources().getColor(R.color.colorAccent), PorterDuff.Mode.SRC_ATOP);
name.getBackground().setColorFilter(getResources().getColor(R.color.colorAccent), PorterDuff.Mode.SRC_ATOP);
also by the SO solutions. But nothing helped.
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
....
<item name="android:editTextStyle">#style/EditTextStyle</item>
</style>
<style name="EditTextStyle" parent="Widget.AppCompat.EditText">

This is what i got after implementing drawable.
Thank you..

It simply consists of overriding the value for colorControlActivated, colorControlHighlight and colorControlNormal in your app theme definition
<style name="Theme.App.Base" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorControlNormal">#c5c5c5</item>
<item name="colorControlActivated">#color/accent</item>
<item name="colorControlHighlight">#color/accent</item>
</style>
or by java
editText.getBackground().mutate().setColorFilter(getResources().getColor(R.color.your_color), PorterDuff.Mode.SRC_ATOP);

by changing your "colorAccent" color you will change color or edittext bottom line and text input layout as well.

Create textfield_bg_drawable.xml in drawable folder. and set it as background resource in EditText.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="2dp"
android:left="-2dp"
android:right="-2dp"
android:top="-2dp">
<selector>
<item
android:state_enabled="true"
android:state_focused="true">
<shape android:shape="rectangle">
<stroke
android:width="2dp"
android:color="#color/focused_line_color" />
</shape>
</item>
<item android:state_enabled="true">
<shape android:shape="rectangle">
<stroke
android:width="1dp"
android:color="#color/normal_line_color" />
</shape>
</item>
</selector>
</item>
</layer-list>

Try with this following code properly working on my side
Drawable drawable = editText.getBackground(); // get current EditText drawable
drawable.setColorFilter(Color.GREEN, PorterDuff.Mode.SRC_ATOP); // change the drawable color
if (Build.VERSION.SDK_INT > 16) {
editText.setBackground(drawable); // set the new drawable to EditText
} else {
editText.setBackgroundDrawable(drawable); // use setBackgroundDrawable because setBackground required API 16
}
Where editText is the id of your EditText

I think it is because Your 1st editText focusing, when your alert layout appear.
add this line in your editText
android:focusable="true"

You need to disable focus from your first edittext when the activity is opened, so set
android:requestFocus= "false"
in your xml file. Or try the following
edittext.clearFocus();
in your java file.
It will not pick your primary color then.
Hope it works!

How to remove extra padding or margin in material design button?

I am trying to create an button which is attached to the TextView above the button as shown in the below image.
The above screenshot is taken from the Note 4 and the OS version is 5.0.1.
Below is the code is used to achieve the UI.
layout/xyz.xml
<Button
android:layout_width="250dp"
android:layout_height="50dp"
android:theme="#style/myButton"
android:text="Cancel"/>
values-v21/style.xml
<style name="myButton" parent="#style/Base.Widget.AppCompat.Button">
<item name="android:colorButtonNormal">#3578A9</item>
<item name="android:inset">0dp</item>
</style>
But if I run the same code in Nexus4 OS verison 5.1.1, the button is taking the margin for all the 4 sides and the screenshot looks like below.
If I remove the "android:theme" and provide the "android:background", the UI looks like the first image. But It won't give the ripple effect. So how the achieve the UI as first image with the ripple effect.

android:insetBottom="0dp"
<com.google.android.material.button.MaterialButton
android:id="#+id/button"
android:layout_width="match_parent"
android:layout_height="56dp"
android:text="Edit"
app:cornerRadius="0dp"
android:insetBottom="0dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent" />

Step 1: Put the below code in styles.xml
<style name="myColoredButton">
<item name="android:textColor">#FF3E96</item>
<item name="android:padding">0dp</item>
<item name="android:minWidth">88dp</item>
<item name="android:minHeight">36dp</item>
<item name="android:elevation">1dp</item>
<item name="android:translationZ">1dp</item>
<item name="android:background">#FF0000</item>
</style>
Here you can change the textColor( I have used #FF3E96 above) and background color (I have used #FF0000) for your button. You can also override textColor values from your Button related layout xml by using android:colorButtonNormal.
Step 2:Create a new XML file under drawables folder and add the following code: I named my XML file as primary.xml
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#color/colorPrimary">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="1dp" />
<solid android:color="#8B8386" />
</shape>
</item>
</ripple>
Step 3: Use the style and drawable in your Button as follows.
<Button
style="#style/myColoredButton"
android:layout_width="250dp"
android:layout_height="50dp"
android:text="Cancel"
android:gravity="center"
android:background="#drawable/primary_round"
android:colorButtonNormal="#3578A9" />
Hope it solves your problem.

I also had issue related to top and bottom spacing for Apply button as you can see above image.
I wanted to show button with uniform background without any spacing as you can see for "Reset" button.
But I have to set both property button background as well as background Tint to same color to achieve this.
If I reuse this buttons at more than one place then I have to programmatically change 2 property to change background color of button.
You can try below solution:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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="wrap_content"
android:orientation="horizontal">
<com.google.android.material.button.MaterialButton
android:id="#+id/btnLeftOk"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:filterTouchesWhenObscured="true"
android:gravity="center"
android:text="#string/apply"
android:textColor="#color/white"
app:backgroundTint="#color/primary_dark_gray"
app:cornerRadius="0dp" />
<com.google.android.material.button.MaterialButton
android:id="#+id/btnRightCancel"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:filterTouchesWhenObscured="true"
android:gravity="center"
android:text="#string/reset"
android:insetTop="0dp"
android:insetBottom="0dp"
android:textColor="#color/white"
app:cornerRadius="0dp"
app:backgroundTint="#color/btn_background_gray" />
</LinearLayout>
After applying below property to "Reset" button.
android:insetTop="0dp"
android:insetBottom="0dp"
Button spacing will be removed from top and bottom. It will occupy spacing with button color. (like in Reset button)
Button background can be changed using one property app:backgroundTint.

How can I style the buttons like these in my Android application?

I would like to style the buttons in my Android application like this:
Whats the easiest way to create the buttons like above?
Currently I simply have a rectangle, here is the xml:
<Button
android:id="#+id/Main_DownloadCenter"
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_marginBottom="25dp"
android:layout_marginLeft="90dp"
android:layout_marginRight="90dp"
android:background="#drawable/main_button_about_state"
android:text="txt" >
</Button>
What I need to do now is add the extra small rectangles that are on both sides of the main big rectangle. Meaning add a small_rect_grey and after that small_rect_aqua .. how can I achieve that?
