Change the TextInputLayout outline box color programmatically - android

I would like to change outline of the TextInputLayout programmatically, but I cannot seem to get it to work. There is an option to do it via XML (question by other SO user using XML), but that is unusable for me as I need to have dynamic coloring. I currently have the following layout:
<com.google.android.material.textfield.TextInputLayout
style="#style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
android:id="#+id/color_outline"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<com.google.android.material.textfield.TextInputEditText
android:id="#+id/color"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Choose color"/>
</com.google.android.material.textfield.TextInputLayout>
I've attempted to apply coloring by looking at the various box methods of the TextInputLayout, but it did not have any effect.
internal fun String.toIntColor() = Integer.parseInt(this.replaceFirst("#", ""), 16)
val colorOutline: TextInputLayout = view.findViewById(R.id.color_outline)
colorOutline.boxStrokeColor = "#006699".toIntColor()
How can I color it dynamically, like in the picture below?
Current situation:
Desired situation: (photoshopped)
Similar question, but focussing on XML

You can the method setBoxStrokeColorStateList.
Something like:
//Color from rgb
int color = Color.rgb(255,0,0);
//Color from hex string
int color2 = Color.parseColor("#FF11AA");
int[][] states = new int[][] {
new int[] { android.R.attr.state_focused}, // focused
new int[] { android.R.attr.state_hovered}, // hovered
new int[] { android.R.attr.state_enabled}, // enabled
new int[] { } //
};
int[] colors = new int[] {
color,
color,
color,
color2
};
ColorStateList myColorList = new ColorStateList(states, colors);
textInputLayout.setBoxStrokeColorStateList(myColorList);

In Kotlin
I have modified the #Gabriele's answer to make it working for me
You can define an extension function as :
private fun TextInputLayout.setBoxStrokeColorSelector() {
//Color from rgb
int color = Color.rgb(255,0,0);
//Color from hex string
val defaultColor = ContextCompat.getColor(context,R.color.indicator_def)
val states = arrayOf {
intArrayOf(android.R.attr.state_focused), // focused
// intArrayOf(android.R.attr.state_hovered), // hovered
intArrayOf(android.R.attr.state_enabled), // enabled
intArrayOf() // default
}
val colors = intArrayOf(color, // focused color
/*color,*/ // hovered color
color, // enabled color
defaultColor) // default color
val myColorList = ColorStateList(states, colors)
setBoxStrokeColorStateList(myColorList)
}
and just call it for any TextInputLayout in your app like
TextInputLayout.setBoxStrokeColorSelector(ContextCompat.getColor(this, R.color.colorPrimary))

Show Dynamic colors on recyclerview list numberings

I want to achieve something like this:
See the image here
A list with circular shape drawable with a fill of a light variant color of the image tint color
I have tried textrdrawablelibrary but it does not give me the same. I have tried the following code too but to no avail:
public int darkenColor(int color) {
float[] hsv = new float[3];
Color.colorToHSV(color, hsv);
hsv[2] *= 0.8f; // value component
color = Color.HSVToColor(hsv);
return color;
}
public String[] mColors = {
"5E97F6",
"9CCC65",
"FF8A65",
"9E9E9E",
"9FA8DA",
"90A4AE",
"AED581",
"F6BF26",
"FFA726",
"4DD0E1",
"BA68C8",
"A1887F",
};
// all colors used by gmail application :)
light colors
// genrating random num from 0 to 11 because you can add more or less
int i1 = new Random().nextInt(11);
//genrating shape with colors
GradientDrawable draw = new GradientDrawable();
draw.setShape(GradientDrawable.OVAL);
draw.setColor(Color.parseColor ("#"+mColors[i1]));
// assigning to textview
contact_name_circle.setBackground(draw); //textview

setStrokeColor not working programmatically

I'm trying to set my color for the outline of my button, but I don't get it to work
I'm using material button and when I use
button.setStrokeColorResource(Color.parseColor(#e4dcd4))
is not working and tells me this
Expected a color resource id (R.color.) but received an RGB integer
I tried almost everything I could found about in stack, but I can't get it to set this strokeColor programmatically
Edit
Almost all setColors use #ColorInt , but this strokeColor uses #ColorRes, which is not working for me, also there is setStrokeColor
public void setStrokeColor(#Nullable ColorStateList strokeColor) {
if (isUsingOriginalBackground()) {
materialButtonHelper.setStrokeColor(strokeColor);
}
}
But I can't get it to work either.
It worked like this
val colorInt = Color.parseColor("#e4dcd4")
val csl = ColorStateList.valueOf(colorInt)
my_button.strokeColor = csl
You might try this
button.setStrokeColor(ContextCompat.getColor(this, R.color.your_color_xml));
Other way you can do is
ShapeDrawable gradientDrawable = (ShapeDrawable)button.getBackground();
gradientDrawable.setStroke(2, your_color);
Also as #Gabriele said you can get an int as a color as :
//From RGB
int colorRGB = Color.rgb(255,0,0);
//From HEX String
int colorHEX = Color.parseColor("#FF11AA");
You have to set the width of the stroke because the default value is 0.
<Button
app:strokeWidth="2dp"
../>
button.strokeColor = ColorStateList.valueOf(Color.parseColor("#e4dcd4"))
or
// if color define in color.xml
button.strokeColor = ColorStateList.valueOf(ContextCompat.getColor(this, R.color.yourColorCOde))
// if you have different state and you want to set programmatically then do as :-
var states = arrayOf(
intArrayOf(R.attr.state_enabled),
intArrayOf(-R.attr.state_enabled),
intArrayOf(-R.attr.state_checked),
intArrayOf(R.attr.state_pressed)
)
// Color list define respect of state
var colors = intArrayOf(
Color.BLACK,
Color.RED,
Color.GREEN,
Color.BLUE
)
// Set stroke color
button.strokeColor = ColorStateList(states, colors)

Set GradientDrawable Color in Adapter

I got the color from the button background and store as a String in the database. Later I want to use this color String in my recyclerView adapter to set the color of my TextView. Below is my code:
#Override
public void onBindViewHolder(NoteListAdapter.NoteListHolder holder, int position) {
current = data.get(position);
final String text = current.getText();
final String get_tag_text = current.getTag();
final String get_tag_color = current.getTag_color();
int[] colors = {Color.parseColor(get_tag_color)};
GradientDrawable gd = new GradientDrawable(GradientDrawable.Orientation.TOP_BOTTOM, colors);
holder.note_text.setText(text);
holder.tv_tag_text.setBackground(gd);
holder.tv_tag_text.setText(get_tag_text);
}
The error I got is "Unknown color". The saved color format in the database is (The saved color format is android.graphics.drawable.GradientDrawable#d1790a4)
Below is the code to get the color from a button background drawable file and also my button xml code
color = (GradientDrawable) tag_watchlist.getBackground().mutate();
tag_color= color.toString();
<Button
android:id="#+id/tag_watch"
style="#style/tag_buttons"
android:background="#drawable/watchlist_button"
android:text="Watchlist" />
drawable file code for the button background
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
android:padding="10dp">
<solid android:color="#a40ce1"/>
<corners android:radius="10dp"/>
</shape>
Can anyone tell me how to resolve this issue??
Edited answer
You are getting exception Caused by: java.lang.IllegalArgumentException: Unknown color mean that you are not passing the color in supported formats to method Color.parseColor.
Make sure you pass the values in following format
#RRGGBB
#AARRGGBB
Here is the valid example
Color.parseColor("#FF4081")
For more information look at documentation Color.parseColor
As per your requirement, you can achieve this API level 24 onward. If you are using current minSdkVersion 24, try below
Change your model class to save color as Integer instead String.
GradientDrawable gradientDrawable = (GradientDrawable) tag_watchlist.getBackground().mutate();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
int color = gradientDrawable.getColor().getDefaultColor();
Log.d("TAG","Color is :"+color);
current.setTagColor(color); // where current is your model class
}
To get the color back from model
int color = current.getTagColor();
You need to provide at least two colors for the GradientDrawable the startColor and the endColor
It will probably throw an exception java.lang.IllegalArgumentException: needs >= 2 number of colors with this code:
int[] colors = {Color.parseColor(get_tag_color)};
GradientDrawable gd = new GradientDrawable(GradientDrawable.Orientation.TOP_BOTTOM, colors);
Change your code with this:
int[] colors = {Color.parseColor(start_color), Color.parseColor(end_color)};
GradientDrawable gd = new GradientDrawable(GradientDrawable.Orientation.TOP_BOTTOM, colors);
If you have get_tag_color for both of your startColor and endColor then replace accordingly but that won't be helpful with GradientDrawable.

TextInputLayout changing color programmatically

I would like to change the color style for the text input layout programmatically. The color is changing any moment so I need to set the color of the underline and hint text with the color I get from my server.
I could change the hint text color with the following code from another answer, but I can not change the underline color:
public static void setInputTextLayoutColor(TextInputLayout textInputLayout, #ColorInt int color) {
try {
Field fDefaultTextColor = TextInputLayout.class.getDeclaredField("mDefaultTextColor");
fDefaultTextColor.setAccessible(true);
fDefaultTextColor.set(textInputLayout, new ColorStateList(new int[][]{{0}}, new int[]{ color }));
Field fFocusedTextColor = TextInputLayout.class.getDeclaredField("mFocusedTextColor");
fFocusedTextColor.setAccessible(true);
fFocusedTextColor.set(textInputLayout, new ColorStateList(new int[][]{{0}}, new int[]{ color }));
} catch (Exception e) {
e.printStackTrace();
}
}
Try this
textInputLAyout.getEditText().getBackground().mutate().setColorFilter(your_color), PorterDuff.Mode.SRC_ATOP);

Randomly Displaying Background Color in Android App

I am currently working on an android APP and I have a list of predefined color in my colors.xml.
Now what I want to achieve is that I want to give the user the opportunity of selecting a color and from the color the user select, I want to display various color (randomly) in the background that matches the global color the user selects, such that those colors will be changing at interval. These colors that will be displayed randomly are already defined in my colors.xml file
Any Guidance or a lead sample on this requirement will be invaluable.
Thank you in advance
private int[] colors = {Color.RED, Color.YELLOW, Color.BLUE, Color.CYAN, Color.GREEN};
Random ranndom = new Random();
int ranndomColor = ranndom.nextInt(5);
whatever.setBackground(colors[ranndomColor]);
or get the colors from "colors.xml:
int color1 = getResources().getColor(R.color.color1);
int color2 = getResources().getColor(R.color.color2);
int color3 = getResources().getColor(R.color.color3);
int color4 = getResources().getColor(R.color.color4);
int color5 = getResources().getColor(R.color.color5);
private int[] colors = {color1, color2, color3, color4, color5};
Random ranndom = new Random();
int ranndomColor = ranndom.nextInt(5);
whatever.setBackground(colors[ranndomColor]);
