Change progressbar color through CODE ONLY in Andr

问题:

I have a progressBar using the ProgressBar class.

Just doing this:

progressBar = new ProgressBar(this, null, android.R.attr.progressBarStyleHorizontal);

I need to change the color of that one, using input value like so:

int color = "red in RGB value".progressBar.setColor(color)

or something like that...

I can't use an XML layout because the progress bar is customizable for users.

回答1:

This will help much no need to do so much coding :)

ProgressBar spinner = new android.widget.ProgressBar(
            context,
            null,
            android.R.attr.progressBarStyle);

spinner.getIndeterminateDrawable().setColorFilter(0xFFFF0000,android.graphics.PorterDuff.Mode.MULTIPLY);

In the case that you need to tint the background and the progress bar in different colors.

progress_drawable.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background">
        <shape android:shape="rectangle" >
            <solid android:color="@color/white" />
        </shape>
    </item>
    <item android:id="@android:id/progress">
        <clip>
            <shape>
                <solid android:color="@color/green" />
            </shape>
        </clip>
    </item>
</layer-list>

Its possible, programmatically, to decompound its layer-list items, and tint them separately:

LayerDrawable progressBarDrawable = (LayerDrawable) progressBar.getProgressDrawable();
Drawable backgroundDrawable = progressBarDrawable.getDrawable(0);
Drawable progressDrawable = progressBarDrawable.getDrawable(1);

backgroundDrawable.setColorFilter(ContextCompat.getColor(this.getContext(), R.color.white), PorterDuff.Mode.SRC_IN);
progressDrawable.setColorFilter(ContextCompat.getColor(this.getContext(), R.color.red), PorterDuff.Mode.SRC_IN);

As I found help on a topic here but can't remember the link, I'm posting my full solution which works great for my needs:

    // Draw a simple progressBar from xml
    progressBar = new ProgressBar(this, null, android.R.attr.progressBarStyleHorizontal);

    // Convert the color (Decimal value) to HEX value: (e.g: #4b96a0)
    String color = colorDecToHex(75, 150, 160);

    // Define a shape with rounded corners
    final float[] roundedCorners = new float[] { 5, 5, 5, 5, 5, 5, 5, 5 };
    ShapeDrawable pgDrawable = new ShapeDrawable(new RoundRectShape(roundedCorners,     null, null));

    // Sets the progressBar color
    pgDrawable.getPaint().setColor(Color.parseColor(color));

    // Adds the drawable to your progressBar
    ClipDrawable progress = new ClipDrawable(pgDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);
    progressBar.setProgressDrawable(progress);

    // Sets a background to have the 3D effect
    progressBar.setBackgroundDrawable(Utils.getActivity().getResources()
            .getDrawable(android.R.drawable.progress_horizontal));

    // Adds your progressBar to your layout
    contentLayout.addView(progressBar);

And here is the code to convert DECIMAL color values to HEXADECIMAL:

public static String colorDecToHex(int p_red, int p_green, int p_blue)
{
    String red = Integer.toHexString(p_red);
    String green = Integer.toHexString(p_green);
    String blue = Integer.toHexString(p_blue);

    if (red.length() == 1)
    {
        red = "0" + red;
    }
    if (green.length() == 1)
    {
        green = "0" + green;
    }
    if (blue.length() == 1)
    {
        blue = "0" + blue;
    }

    String colorHex = "#" + red + green + blue;
    return colorHex;
}

I think the last method is not that clean but it works well.

Hope this well help, too much time wasted on this progressbar.

It is possible to colorize the Progress bar by setting the color filter on the progress bar drawable:

Drawable drawable = progressBar.getProgressDrawable();
drawable.setColorFilter(new LightingColorFilter(0xFF000000, customColorInt));

Update

In newer versions of Android (21 works), you can change the color of a progressbar programmatically by just using setProgressTintList.

To set it red, use:

//bar is a ProgressBar
bar.setProgressTintList(ColorStateList.valueOf(Color.RED));

回答6:

This works for me with AppCompat: DrawableCompat.setTint(progressBar.getProgressDrawable(), tintColor);

回答7:

I have given default color in xml by drawable.

I have changed it programatically.

activity_splasg.xml:

<ProgressBar
       android:id="@+id/splashProgressBar"
       android:progressDrawable="@drawable/splash_progress_drawable"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:max="100"
       android:progress="50"
       style="?android:attr/progressBarStyleHorizontal"
       android:layout_alignParentBottom="true" />

splash_progress_drawable.xml:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background">
        <shape>
            <solid
                android:color="@android:color/transparent" />
        </shape>
    </item>

    <item
        android:id="@android:id/progress">
        <clip>
            <shape>
                <solid
                    android:color="#e5c771" />
            </shape>
        </clip>
    </item>

</layer-list>

Now How to change ProgressDrawable color programatically.

ProgressBar splashProgressBar = (ProgressBar)findViewById(R.id.splashProgressBar);

Drawable bgDrawable = splashProgressBar.getProgressDrawable();
bgDrawable.setColorFilter(Color.BLUE, android.graphics.PorterDuff.Mode.MULTIPLY);
splashProgressBar.setProgressDrawable(bgDrawable);

Hope this will help you.

回答8:

progressbar.setIndeterminateTintList(ColorStateList.valueOf(Color.RED));

It only works above API 21

回答9:

if you want to change color of progress bar programmatically then you copy past this code it is working 100%

 mainProgressBar.getIndeterminateDrawable().setColorFilter(Color.GREEN, PorterDuff.Mode.MULTIPLY);

This post is what you're looking for: How to change progress bar's progress color in Android

If you want the user to choose their own colors, just make multiple-drawable XML files for each color, and select them based on the user's choice.

回答11:

Layout = activity_main.xml:

<ProgressBar
    android:id="@+id/circle_progress_bar_middle"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_centerInParent="true"
    android:max="100"
    android:rotation="-90"
    android:indeterminate="false"
    android:progressDrawable="@drawable/my_drawable_settings2" />

In Java Activity/Fragment:

ProgressBar myProgressBar = (ProgressBar) view.findViewById(R.id.circle_progress_bar_middle);
myProgressBar.setProgressDrawable(getResources().getDrawable(R.my_drawable_settings1));

The my_drawable_settings1.xml file inside your drawable/mipmap folder:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:id="@android:id/progress">
        <shape
            android:innerRadius="55dp"
            android:shape="ring"
            android:thickness="9dp"
            android:useLevel="true">

            <gradient
                android:startColor="#3594d1"
                android:endColor="@color/white"
                android:type="sweep" />
        </shape>
    </item>
</layer-list>

Where my_drawable_settings1 and my_drawable_settings2.xml has different colors.
