showing image as small size in android

Question

My application need to show images from a host url. I am adding the image to the inner layout from class file. But I'm not able to reduce the image size and as you can see it is occupying the complete screen.

hi, you did not set the LinearLayout ll layout params, Please set the width and height. — droidd, Feb 19 '15 at 12:17

You can add com.example.testapp.LoaderImageView as child of your LinearLayout in XML and define it dimension, or add LinearLayout.LayoutParams Dynamically with your desire dimensions. Add this line after com.example.testapp.LoaderImageView image=new LoaderImageView(this, "http://developer.android.com/images/dialog_buttons.png");

int desire_width = 50;
int desire_height = 50;
image.setLayoutParams(new LinearLayout.LayoutParams(desire_width, desire_height));
