Android id naming convention: lower case with underscore vs. camel case

Question

I\'m currently programming an application for the Android. Now what I found out is that you cannot place resource objects, say, an image in the drawable folder and name it l

Answer 1

i think it is good if we use the all small letters with underscores.

Just look at this(Adding to what Daniel had answered)

  // Camel Case
    TextView tvUserName = (TextView) findViewById(R.id.tvUserName);

    // Small Caps and Underscores
    TextView tvUserName = (TextView) findViewById(R.id.tv_user_name);

in my own experience I tend to get a little confused of the camel case convention in xml because when you link it to Java which also uses camel case(because it is the standard) it looks like a doppleganger.
