set extended ImageView width and height programatically - android

问题

I have a custom class that extends ImageView that I'm programatically putting on to a RelativeLayout. I want each one of these images to be a specific width and height. I've tried setting the width/height in code with LayoutParams and with setMaxWidth/setMaxHeight...neither seem to be working.

Here is the code from the constructor of the class:

LayoutParams p = new LayoutParams(50,67);       
        this.setLayoutParams(p);
        this.setImageResource(WhichImage(wi));
        this.setMaxWidth(50);
        this.setMaxHeight(67);

I've moved the call to setImageResource() above and below everything there and it still defaults to the true image size in my drawables...

You probably need to tell the ImageView how to scale. Try using ImageView#setScaleType.
