如何改变android中SeekBar的颜色？ （以编程方式）

Question

I made an equalizer to go with my app but I am not sure how I can change the seekbar's thumb and progress color. It seems to be pink by default and that doesn't fit my app's aesthetics.

 SeekBar seekBar = new SeekBar(this);

        seekBar.setId(i);

        seekBar.setLayoutParams(layoutParams);
        seekBar.setMax(upperEqualizerBandLevel - lowerEqualizerBandLevel);

        seekBar.setProgress(mEqualizer.getBandLevel(equalizerBandIndex));
        //seekBar.setBackgroundColor(Color.DKGRAY);
        //seekBar.setDrawingCacheBackgroundColor(Color.DKGRAY);

Answer 1

To change the color of the Seekbar thumb, create a new style in style.xml

<style name="SeekBarColor"
  parent="Widget.AppCompat.SeekBar"> 
  <item name="colorAccent">@color/your_color</item> 
</style>

Finally in the layout:

<SeekBar
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:theme="@style/SeekBarColor" />

To change the Seekbar progress color, use this in Java Class.

seekBar.getProgressDrawable().setColorFilter("yourcolor", PorterDuff.Mode.MULTIPLY);

Both these will work for API>16.

Edit

To change SeekBar thumb color by Java code.

 seekBar.getProgressDrawable().setColorFilter(getResources().getCo‌​lor(R.color.your_color‌​), PorterDuff.Mode.SRC_ATOP);

Answer 2

虽然使用样式是个好主意，但如果您想以编程方式分配颜色，我建议它不会提供太多灵活性：

//for the progress seekBar.getProgressDrawable().setColorFilter(mThemeColor,PorterDuff.Mode.SRC_ATOP); //for the thumb handle seekBar.getThumb().setColorFilter(mThemeColor, PorterDuff.Mode.SRC_ATOP);

Answer 3

You can change seekbar thumb and progress colors for programmatically like this:

   seekBar.getProgressDrawable().setColorFilter(Utils.getAccentColor(this), PorterDuff.Mode.SRC_IN);
   seekBar.getThumb().setColorFilter(Utils.getAccentColor(this), PorterDuff.Mode.SRC_IN);

Answer 4

You can easily change it via code,

For example:

seekbar.setProgressTintList(ColorStateList.valueOf(Color.parseColor(#000000)));

or

seekbar.setProgressTintList(ColorStateList.valueOf(Color.RED));

Hoping that it will be helpfull for someone in future.

Answer 5

You need to call you seekbar like this

SeekBar newSeek = new SeekBar(this, null, R.style.YOUR_NEW_STYLE);

where YOUR_NEW_STYLE will define the colors of the Seekbar that you want.

Answer 6

试试这个：

seekBar.getProgressDrawable().setColorFilter(getResources().getColor(R.color.mcolor), PorterDuff.Mode.MULTIPLY);

Answer 7

Just a little more peachy answer

public static void setSeekBarColor(SeekBar seekBar, int color) {
    seekBar.getProgressDrawable().setColorFilter(color, PorterDuff.Mode.MULTIPLY);
    seekBar.getThumb().setColorFilter(color, PorterDuff.Mode.SRC_ATOP);
}

Answer 8

Kotlin version, and without using deprecated methods:

val colorFilter = BlendModeColorFilterCompat.createBlendModeColorFilterCompat(
    Resources.getSystem().getColor(R.color.your_color, null),
    BlendModeCompat.SRC_ATOP
)

// SeekBar progress color
seekBar.progressDrawable.colorFilter = colorFilter
// SeekBar thumb handle color
seekBar.thumb.colorFilter = colorFilter

Answer 9

    //seekBar.setBackgroundColor(Color.DKGRAY);
    //seekBar.setDrawingCacheBackgroundColor(Color.DKGRAY);

There are few Views in Android SDK (ProgressBar is another example) in which you have to change colour using graphical color filters, instead of changing Background / Foreground source colour.

Find .setColorFilter() method, supply your source colour into it with some PorterDuff filter, like .Mode.MULTIPLY (depending on what filter mode you like best) and there you go.

Example:

seekBar.setColorFilter(new PorterDuffColorFilter(srcColor,PorterDuff.Mode.MULTIPLY));
