How can I set the background of my activity with a drawable image and give it a custom size?
The width of the background image should match the parent's but the height of background image should be x dp(s) smaller than the parent's, where I can adjust the value of x, so if my screen size is 1920 x 1080
and x = 200
, the background image should be 1920 x 880
in size.
Can this be done using drawable or canvas?
Programmatically get the actual image size and set the custom size, have look this
Display display = getWindowManager().getDefaultDisplay();
ImageView iv = (LinearLayout) findViewById(R.id.imageview);
int width = display.getWidth(); // return image width
int height = display.getHeight();// return actual height
//now set custom size
int actual_size = height - 200;
LinearLayout.LayoutParams parms = new LinearLayout.LayoutParams(width,actual_size );
iv.setLayoutParams(parms);
//for constraint layout
ConstraintLayout.LayoutParams newParams = new ConstraintLayout.LayoutParams(width,actual_size);
iv.setLayoutParams(newParams );
Hope it will help you!!
