Answer 1

In XML use src not background tag in ImageView. In java code-

import android.graphics.PorterDuff.Mode;
final Context context=this;

        home1=(ImageView) findViewById(R.id.home1);
 Resources res = context1.getResources();
        final int newColor = res.getColor(android.R.color.black);
        home1.setColorFilter(newColor, Mode.SRC_ATOP);

Answer 2

Set android:tint attribute of image/image button to the color you need.

android:tint="@android:color/black"

Optionally you can set android:tintMode attribute.

Answer 3

imageView.setImageResource(R.drawable.ic_person_black_48dp);

imageView.setColorFilter(imageView.getContext().getResources().getColor(R.color.desired_color), PorterDuff.Mode.SRC_ATOP);

Answer 4

Put this in your OnDraw, just before you draw your square.

if (userclicked){
paint.setColor(Color.GREEN);
} else {
paint.setColor(Color.BLACK);
}

Of course that is if you are drawing it with canvas.drawRect(x0,y0,x1,y1,paint) which you would if you were drawing a simple shape like that.

Answer 5

Here's how I do this: It's pulling the color from a resource xml file.

<resources>
<color name="new_color">#FFAAAAAA</color>
</resources>

In your activity .java file:

import android.graphics.PorterDuff.Mode;

Resources res = context.getResources();
final ImageView image = (ImageView) findViewById(R.id.imageId);
final int newColor = res.getColor(R.color.new_color);
image.setColorFilter(newColor, Mode.SRC_ATOP);

To clear it call:

image.setColorFilter(null);

Answer 6

Create resource in drawable folder like

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <bitmap
            android:src="@drawable/rect"
            android:tint="@color/red"/>
    </item>
</layer-list>

android:tint="@color/red" does it.
