如何在 Android 中更改 Drawable 的颜色？

我认为您实际上可以只使用 Drawable.setColorFilter( 0xffff0000, Mode.MULTIPLY )。这会将白色像素设置为红色，但我认为它不会影响透明像素。

请参阅Drawable#setColorFilter

---

试试这个代码：

ImageView lineColorCode = (ImageView)convertView.findViewById(R.id.line_color_code);
int color = Color.parseColor("#AE6118"); //The color u want             
lineColorCode.setColorFilter(color);

---

我知道这个问题是在 Lollipop 之前提出的，但我想在 Android 5.+ 上添加一个很好的方法来做到这一点。您制作了一个引用原始文件的 xml 可绘制对象并在其上设置色调，如下所示：

<?xml version="1.0" encoding="utf-8"?>
<bitmap
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:src="@drawable/ic_back"
    android:tint="@color/red_tint"/>

---

新的支持 v4 将色调带回 api 4。

你可以这样做

public static Drawable setTint(Drawable d, int color) {
    Drawable wrappedDrawable = DrawableCompat.wrap(d);
    DrawableCompat.setTint(wrappedDrawable, color);
    return wrappedDrawable;
}

---

如果您有一个纯色的可绘制对象并且您想将其更改为不同的纯色，您可以使用 ColorMatrixColorFilter。透明度得以保留。

int iColor = Color.parseColor(color);

int red   = (iColor & 0xFF0000) / 0xFFFF;
int green = (iColor & 0xFF00) / 0xFF;
int blue  = iColor & 0xFF;

float[] matrix = { 0, 0, 0, 0, red,
                   0, 0, 0, 0, green,
                   0, 0, 0, 0, blue,
                   0, 0, 0, 1, 0 };

ColorFilter colorFilter = new ColorMatrixColorFilter(matrix);
drawable.setColorFilter(colorFilter);

---

我还将 ImageView 用于图标（在 ListView 或设置屏幕中）。但我认为有更简单的方法可以做到这一点。

使用 tint 更改所选图标上的颜色叠加。

在 xml 中，

android:tint="@color/accent"
android:src="@drawable/ic_event" 

工作正常，因为它来自 AppCompat

---

您应该对所有 API 执行此操作：

Drawable myIcon = getResources().getDrawable( R.drawable.button ); 
ColorFilter filter = new LightingColorFilter( Color.BLACK, Color.BLACK);
myIcon.setColorFilter(filter);

---

我可以使用以下代码来做到这一点，该代码取自一个活动（布局非常简单，仅包含一个 ImageView，此处不发布）。

private static final int[] FROM_COLOR = new int[]{49, 179, 110};
private static final int THRESHOLD = 3;

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.test_colors);

    ImageView iv = (ImageView) findViewById(R.id.img);
    Drawable d = getResources().getDrawable(RES);
    iv.setImageDrawable(adjust(d));
}

private Drawable adjust(Drawable d)
{
    int to = Color.RED;

    //Need to copy to ensure that the bitmap is mutable.
    Bitmap src = ((BitmapDrawable) d).getBitmap();
    Bitmap bitmap = src.copy(Bitmap.Config.ARGB_8888, true);
    for(int x = 0;x < bitmap.getWidth();x++)
        for(int y = 0;y < bitmap.getHeight();y++)
            if(match(bitmap.getPixel(x, y))) 
                bitmap.setPixel(x, y, to);

    return new BitmapDrawable(bitmap);
}

private boolean match(int pixel)
{
    //There may be a better way to match, but I wanted to do a comparison ignoring
    //transparency, so I couldn't just do a direct integer compare.
    return Math.abs(Color.red(pixel) - FROM_COLOR[0]) < THRESHOLD &&
        Math.abs(Color.green(pixel) - FROM_COLOR[1]) < THRESHOLD &&
        Math.abs(Color.blue(pixel) - FROM_COLOR[2]) < THRESHOLD;
}

---

您可以使用 Android 支持兼容库来解决它。 :)

 // mutate to not share its state with any other drawable
 Drawable drawableWrap = DrawableCompat.wrap(drawable).mutate();
 DrawableCompat.setTint(drawableWrap, ContextCompat.getColor(getContext(), R.color.your_color))

---

在您的活动中，您可以使用单一颜色为您的 PNG 图像资源着色：

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    myColorTint();
    setContentView(R.layout.activity_main);
}

private void myColorTint() {
    int tint = Color.parseColor("#0000FF"); // R.color.blue;
    PorterDuff.Mode mode = PorterDuff.Mode.SRC_ATOP;
    // add your drawable resources you wish to tint to the drawables array...
    int drawables[] = { R.drawable.ic_action_edit, R.drawable.ic_action_refresh };
    for (int id : drawables) {
        Drawable icon = getResources().getDrawable(id);
        icon.setColorFilter(tint,mode);
    }
}

现在，当您使用 R.drawable.* 时，它应该使用所需的色调进行着色。如果您需要其他颜色，那么您应该能够 .mutate() 可绘制对象。

---

如果您将可绘制设置为 ImageView，则可以使用 1 衬里：

yourImageView.setColorFilter(context.getResources().getColor(R.color.YOUR_COLOR_HERE);

---

view.getDrawable().mutate().setColorFilter(0xff777777, PorterDuff.Mode.MULTIPLY); 

感谢@sabadow

---

此代码段对我有用：

PorterDuffColorFilter porterDuffColorFilter = new PorterDuffColorFilter(getResources().getColor(R.color.your_color),PorterDuff.Mode.MULTIPLY);

imgView.getDrawable().setColorFilter(porterDuffColorFilter);
imgView.setBackgroundColor(Color.TRANSPARENT)

---

为时已晚，但万一有人需要它：

   fun setDrawableColor(drawable: Drawable, color: Int) :Drawable {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            drawable.colorFilter = BlendModeColorFilter(color, BlendMode.SRC_ATOP)
            return drawable
        } else {
            drawable.setColorFilter(color, PorterDuff.Mode.SRC_ATOP)
            return drawable
        }
    }

---

这适用于所有有背景的东西：

文本视图，按钮...

TextView text = (TextView) View.findViewById(R.id.MyText);
text.setBackgroundResource(Icon);    
text.getBackground().setColorFilter(getResources().getColor(Color), PorterDuff.Mode.SRC_ATOP);

---

有很多解决方案，但没有人建议如果颜色资源 xml 文件已经有颜色，那么我们也可以直接从那里选择，如下所示：

ImageView imageView = (ImageView) findViewById(R.id.imageview);
imageView.setColorFilter(getString(R.color.your_color));

根据 isWorking 字段更改可绘制颜色的简短示例。

我的形状xml：

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="@android:color/holo_blue_bright" />
    <corners android:radius="30dp" />
    <size
        android:height="15dp"
        android:width="15dp" />
</shape>

我的改变方法：

private Drawable getColoredDrawable(int drawableResId, boolean isworking) {
    Drawable d = getResources().getDrawable(R.drawable.shape);
    ColorFilter filter = new LightingColorFilter(
            isworking ? Color.GREEN : Color.RED,
            isworking ? Color.GREEN : Color.RED);
    d.setColorFilter(filter);
    return d;
}

使用示例：

text1.setCompoundDrawablesWithIntrinsicBounds(getColoredDrawable(R.drawable.shape, isworking()), null, null, null);

---

Int color = Color.GRAY; 
// or int color = Color.argb(123,255,0,5);
// or int color = 0xaaff000;

在 XML /res/values/color.xml

<?xml version="1.0" encoding="utf-8">
<resources>
    <color name="colorRed">#ff0000</color>
</resoures> 

Java 代码

int color = ContextCompat.getColor(context, R.color.colorRed);

GradientDrawable drawableBg = yourView.getBackground().mutate();
drawableBg.setColor(color);

---

它适用于一些简单的drawables。我在一个简单的带圆角的纯色矩形上使用它，并且需要用不同的布局改变颜色。

尝试这个

android:backgroundTint="#101010"

---

试试 android:backgroundTint="@color/quantum_black_100"

---

使用视图绑定的 Koltin 解决方案：

binding.avatar.drawable.colorFilter = BlendModeColorFilterCompat.createBlendModeColorFilterCompat(R.color.white, BlendModeCompat.SRC_ATOP)

这使用了最新版本的核心 androidx 库。

---

我刚刚遇到了这个问题并通过替换解决了它：

android:tint="@color/yellow_800"

到以下

app:tint="@color/yellow_800"

---

当您使用库为您执行此操作时，这非常简单。试试这个library

你可以这样调用：

Icon.on(holderView).color(R.color.your_color).icon(R.mipmap.your_icon).put();
