I was able to do this with the following code, which is taken from an activity (the layout is a very simple one, just containing an ImageView, and is not posted here).

<pre><code>private static final int[] FROM_COLOR = new int[]{49, 179, 110};

 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 &lt; bitmap.getWidth();x++)
 for(int y = 0;y &lt; 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]) &lt; THRESHOLD &amp;&amp;
 Math.abs(Color.green(pixel) - FROM_COLOR[1]) &lt; THRESHOLD &amp;&amp;

blocks|key|233307|text|我认为你实际上可以直接使用Drawable.setColorFilter(+0xffff0000,+Mode.MULTIPLY+)。这会将白色像素设置为红色，但我不认为它会影响透明像素。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|233308|请参阅Drawable#setColorFilter|233309|entityMap|0|LINK|mutability|MUTABLE|url|http://developer.android.com/reference/android/graphics/drawable/Drawable.html#setColorFilter%2528int,%2520android.graphics.PorterDuff.Mode%2529^0|D|1G|0|3|N|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|S|8|@]|D|@$9|T|A|U|1|V]]|E|$]]|$1|H|3|-4|5|6|7|W|8|@]|D|@]|E|$]]]|I|$J|$5|K|L|M|E|$N|O]]]]

I think you can actually just use <code>Drawable.setColorFilter( 0xffff0000, Mode.MULTIPLY )</code>. This would set white pixels to red but I don't think it would affect the transparent pixels.

See <a href="http://developer.android.com/reference/android/graphics/drawable/Drawable.html#setColorFilter%28int,%20android.graphics.PorterDuff.Mode%29" rel="noreferrer">Drawable#setColorFilter</a>

If you have a drawable that's a solid color and you want to change it to a differnet solid color, you can use a <code>ColorMatrixColorFilter</code>. Transparency is preserved.

<pre><code>int iColor = Color.parseColor(color);

int red = (iColor &amp; 0xFF0000) / 0xFFFF;
int green = (iColor &amp; 0xFF00) / 0xFF;
int blue = iColor &amp; 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);
</code></pre>

blocks|key|233467|text|在您的活动中，您可以使用单一颜色对PNG图像资源进行着色：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|233468|protected+void+onCreate(Bundle+savedInstanceState)+{

In your Activity you can tint your PNG image resources with a single colour:

<pre><code>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);
 }
}
</code></pre>

Now when you use the R.drawable.* it should be coloured with the desired tint. If you need additional colours then you should be able to .mutate() the drawable.

I know this question was ask way before Lollipop but I would like to add a nice way to do this on Android 5.+. You make an xml drawable that references the original one and set tint on it like such:

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;bitmap
 xmlns:android="http://schemas.android.com/apk/res/android"

Short example to change drawable color according to <code>isWorking</code> field.

My shape xml:

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

My method to change:

<pre><code>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;
}
</code></pre>

Example of usage:

<pre><code>text1.setCompoundDrawablesWithIntrinsicBounds(getColoredDrawable(R.drawable.shape, isworking()), null, null, null);
</code></pre>

I also use <code>ImageView</code> for icons (in <code>ListView</code> or settings screen). But I think there is much simpler way to do that.

Use <code>tint</code> to change the color overlay on your selected icon.

In xml,

<pre><code>android:tint="@color/accent"
android:src="@drawable/ic_event" 
</code></pre>

works fine since it comes from <code>AppCompat</code>

blocks|key|4556292|text|有很多解决方案，但是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挑选，如下所示：|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|4556293|ImageView+imageView+=+(ImageView)+findViewById(R.id.imageview);
imageView.setColorFilter(getString(R.color.your_color));|code-block|syntax|javascript|4556294|entityMap^0|H|7|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

There are so many solution but nobody suggested if the color resource xml file already have color then we can pick directly from there also as below:

imageView.setColorFilter(getString(R.color.your_color));

You can solve it using Android support compat libraries. :)

 Drawable drawableWrap = DrawableCompat.wrap(drawable).mutate();
 DrawableCompat.setTint(drawableWrap, ContextCompat.getColor(getContext(), R.color.your_color))

I'm working on an android application, and I have a drawable that I'm loading up from a source image. On this image, I'd like to convert all of the white pixels to a different color, say blue, and then cache the resultant Drawable object so I can use it later.

So for example say I have a 20x20 PNG file that has a white circle in the middle, and that everything outside the circle is transparent. What's the best way to turn that white circle blue and cache the results? Does the answer change if I want to use that source image to create several new Drawables (say blue, red, green, orange, etc)?

I'm guessing that I'll want to use a ColorMatrix in some way, but I'm not sure how.
