仅在Android中通过CODE更改进度条颜色

Question

我有一个使用ProgressBar类的progressBar.

这样做:

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

我需要使用输入值来改变那个的颜色,如下所示:

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

或类似的东西...

我无法使用XML布局,因为进度条可以为用户自定义.

Answer 1

这将有助于更多的编码:)

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

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

Answer 2

如果您需要以不同颜色着色背景和进度条.

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>

以编程方式可以分解其图层列表项,并分别对它们进行着色:

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);

由于我在这里找到了关于某个主题的帮助但却记不起链接,我发布了我的完整解决方案,该解决方案非常适合我的需求:

    // 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);

以下是将DECIMAL颜色值转换为HEXADECIMAL的代码:

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;
}

我认为最后一种方法不是很干净但效果很好.

希望这很有帮助,在这个进度条上浪费了太多时间.

更新

在较新版本的Android(21件作品)中,您只需使用即可以编程方式更改进度条的颜色setProgressTintList.

要将其设置为红色,请使用:

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

Answer 5

可以通过在进度条drawable上设置颜色过滤器来对进度条颜色进行着色:

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

Answer 6

Kotlin 2021：

progressBar.indeterminateTintList = ColorStateList.valueOf(Color.WHITE)

您还可以使用 getColor() 传递资源

如果不是不确定的话，您可能需要这两个：

setSecondaryProgressTintList

setProgressTintList

Answer 7

这适用于AppCompat:DrawableCompat.setTint(progressBar.getProgressDrawable(),tintColor);

Answer 8

如果您想以编程方式更改进度条的颜色，则可以复制此代码，使其可以正常工作100％

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

Answer 9

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

仅适用于API 21以上
