在Android中更改图片的背景色

Question

I found allot about changing the background color of an activity but not how to change the backgroundcolor of an imageview, like this as example:

        <ImageView
            android:id="@+id/imageView2"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="left"
            android:src="@drawable/ic_person_200x200"
            android:layout_margin="10dp"
            android:layout_span="3"
            android:background="#52D017"
            android:padding="1dp" />

Anyone?

Answer 1

In your java code, after creating the ImageView object you can try calling the setBackgroundColor() method which is inherited from View. Check out the docs for more info on this http://developer.android.com/reference/android/view/View.html#setBackgroundColor(int)

Answer 2

If adding android:background attribute to the <ImageView> doesn't work then you should apply it programmatically.

Remove android:background="#52D017" from the <ImageView> and add the following to your activity file

ImageView backgroundImg = (ImageView) findViewById(R.id.imageView2);
backgroundImg.setBackgroundColor(Color.rgb(100, 100, 50));
