A colorful SeekBar for picking color

In version 1.0.2 i used to set seekbar color by setColors(int[] colors), but in version 1.4.3 setColorSeeds() not working anymore.. It change just thumb color of seek bar. Any reason for that?

Greetings @rtugeek Sir, I am a graphic designer and an open source contributor. I would like to contribute to your good project by designing a logo for it which will add more visibility and interest from the users. I will be doing it for free as my gift to your project.

Hi, this is awesome library for color seekbar. i am using library in my project. every thing is working awesome but i am stuck on a point. the point is can we set alpha bar minimum position. i don't want to allow user to set alpha bar position below 70. Is there any way to set alphabar minimum thumb position to 70.

Thanks in advance

relevant xml:

                <com.rtugeek.android.colorseekbar.ColorSeekBar
                    android:id="@+id/colorSlider"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    app:colors="@array/material_colors"
                    />

java.lang.IllegalArgumentException: width and height must be > 0 at android.graphics.Bitmap.createBitmap(Bitmap.java:830) at android.graphics.Bitmap.createBitmap(Bitmap.java:809) at android.graphics.Bitmap.createBitmap(Bitmap.java:776) at com.rtugeek.android.colorseekbar.ColorSeekBar.onSizeChanged(ColorSeekBar.java:174) at android.view.View.sizeChange(View.java:16757) at android.view.View.setFrame(View.java:16719) at android.view.View.layout(View.java:16636) at android.widget.RelativeLayout.onLayout(RelativeLayout.java:1079)

Set up ColorSeekBar like so.

private void setUpColorPicker() {
        colorSlider.setMaxPosition(100);
        colorSlider.setColorSeeds(R.array.material_colors);
        colorSlider.setColorBarPosition(0);
        colorSlider.setBarHeight(5);
        colorSlider.setThumbHeight(30);
        this.color = colorSlider.getColor();

        colorSlider.setOnColorChangeListener(new ColorSeekBar.OnColorChangeListener() {
            @Override
            public void onColorChangeListener(int colorBarPosition, int alphaBarPosition, int color) {
                CourseManageFragment.this.color = color;
            }
        });
    }

// Starts another activity then returns. // Call the following methods

// Where color is a valid color from above ColorSeekBar
int pos = colorSlider.getColorIndexPosition(course.getColor()); // Always returns -1
colorSlider.setColorBarPosition(pos);

Hey. I've been using the library since the v.1.0.2 update. My XML was looking like this one, and it was working as expected:

<com.rtugeek.android.colorseekbar.ColorSeekBar
        android:id="@+id/colorSeekbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="8dp"
        app:color="@array/wheel_colors_7"
        app:maxValue="6"
        app:barHeight="8dp"
        app:colorBarValue="3"/>

However, after updating to the v1.1.2, I changed the XML to works with the latest changes:

<com.rtugeek.android.colorseekbar.ColorSeekBar
        android:id="@+id/colorSeekbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="8dp"
        app:colorSeeds="@array/wheel_colors_7"
        app:maxPosition="6"
        app:barHeight="8dp"
        app:colorBarPosition="3"/>

Then I see that app:colorBarPosition is not working properly, showing "0" as the initial position when a ColorSeekBar is displayed.

I have a color (rgb) and I need to set the thumb at that color?

I have tried to loop over until I find the thumb at that color, like:

mRgbSeekbar.setMaxValue(100);
 private void findSeekBarRgb(int rgb) {
            int current = 0;
            while(current <= 100){
                mRgbSeekBar.setColorBarValue(current);
                int color = mRgbSeekBar.getColor();
                if(rgb == color) return;
                current++;
            }
        }

Is there any convenient method?

I want to disable the colorseekbar when there is some method calls and enable after that work done how can i prevent user to seek colorseekbar?

i tried the setEnabled(boolean enable); but it not works in colorseekbar.

We are using this for ruler purpose and need to show thumb on desired position. For example, I have set minimum value 300 and maximum value 800. Based on some calculation I get some random number between 300-800. So I want to set this value on seekbar.

I need to get the position of the alpha bar and there isn't a method similar to getColorPosition() for the alpha bar. Thanks by the way for this great library :)

Realizing this is a new repo/release...

I just ran across this control, which was exactly what I'm looking for (a very low-profile slider for picking colors I can use in a list). I'm just getting my feet wet with Android, so maybe I'm missing something, but it looks like you are referencing release '1.0.0' in the gradle dependencies, but jitpack.io requires that be an existing release in your github repo... There isn't a release 1.0.0 yet. I tried the "short hash" that jitpack mentions as well, but couldn't get that to work either (I probably am misunderstanding what that is)...

Here is the gradle output.

Error:A problem occurred configuring project ':app'.

Could not resolve all dependencies for configuration ':app:_debugCompile'. Could not find com.rtugeek.android:colorseekbar:1.0.0. Searched in the following locations: https://jitpack.io/com/rtugeek/android/colorseekbar/1.0.0/colorseekbar-1.0.0.pom https://jitpack.io/com/rtugeek/android/colorseekbar/1.0.0/colorseekbar-1.0.0.jar Required by: SampleApplication:app:unspecified

Thoughts? Thanks!!

Is it possible to return a value to the listener callback method to determine whether it is the value of the user's manual sliding, or the value of the callback through setColorSeeds()

Hi there! I was trying to build an app with two ColorSeekBars - one to control the hue of my view and one to control the saturation. When I change my hue colorSeekBar, the colorSeeds of my saturation colorSeekBar change to (Color.WHITE, hueSeekBar.getColor()). This works well, but when I try dragging the saturationSeekBar, the color of the thumb remains unchanged (the original value). How would I go about doing this? Thank you!

Hey!

Thanks for this nice library!!

I'm using it to display temperature values. Therefore it would be great to be able to lock the thumb at set position. Any chance to implement this?

Thanks, Rob

I tried using version 1.4.3, but not resolving it. More recent version I can compile against is 1.4.2, that gives me this error. Switching back to 1.2.2, everything is fine. I make plain usage in XML:

<com.rtugeek.android.colorseekbar.ColorSeekBar android:id="@+id/colorSliderStop" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_below="@id/stopLabel" app:colorSeeds="@array/t16_color_slider" />
