Change ImageView drawable of an inflated layout

Question

I want to change the drawable of imageview, that is saved to disk,, and is available. but when setting drawable, a NullPointerException occurs

The question is, how to change imageview drawable of inflated layout[Source image is "/sdcard/myappfolder/user.png"], the layout is inflated

Here's my part of code:

    intilt = itilt.inflate(R.layout.pic_container, null, false);    //layout is inflated successfully
    picCheck(); // method to check file availability, working perfect, if file exists, returns 1, else returns 0;
    if(picmark == 1){
        Bitmap pch = BitmapFactory.decodeFile(file.getAbsolutePath());
        imageView = (ImageView)findViewById(R.id.contimg);  //contimg is ImageView id from layout pic_container
        imageView.setImageBitmap(pch);  
        /**
        *  Caused by: java.lang.NullPointerException
        *  at com.package.packagename.javaact.onCreate(javaact.java:83)
        */
    }
    else{
        Toast.makeText(this, "File Not Found, setting Default", Toast.LENGTH_SHORT).show();
    }
