implement android:src="@drawable/image" programmatically in Android

Question

I am trying to set the foreground image on an image button. After some research, I came across this code sample:

<ImageButton android:text="Button" android:id="@+id/button1"     android:layout_width="wrap_content"      android:layout_height="wrap_content"     android:src="@drawable/icon"/> 

My query is how to actually implement android:src in code.

Answer 1

Try this:

ImageButton btn = (ImageButton)findViewById(R.id.button1); btn.setImageResource(R.drawable.newimage); 

where newimage is the image name in drawable folder.

try this:

ImageButton btn = (ImageButton)findViewById(R.id.button1); btn.setImageBitmap(bm); 

where bm is bitmap extracted from server.

I see you receive a Drawable; well, do this:

normalImage = Drawable.createFromStream(code); Bitmap bm = ((BitmapDrawable)normalImage).getBitmap(); ImageButton btn = (ImageButton)findViewById(R.id.button1); btn.setImageBitmap(bm); 

Answer 2

Here's what worked for me in setting the image:src on an ImageButton programmatically** or through code:

1.Retrieve the image drawable.

Drawable tempImage = getResources().getDrawable(R.drawable.my_image); 

2.Get the view.

ImageButton tempButton = (ImageButton)findViewById(R.id.my_image_button); 

3.Set the image for the view.

tempButton.setImageDrawable(tempImage); 

Hope this works for you too!
