you can get all EditTexts in your View by this method :

Method to get all EditTexts in a View

also you can create a map that contains "ID ,Textview"

    HashMap<Integer,EditText> myEditTextList = new HashMap<Integer,EditText>();

    for( int i = 0; i < myLayout.getChildCount(); i++ )
        if( myLayout.getChildAt( i ) instanceof EditText )
            myEditTextList.put(  ((EditText) myLayout.getChildAt( i )).getId() , 
                   ((EditText) myLayout.getChildAt( i )));

You can initialize all TextViews by renaming them to "tv1 ... tv50", and use this code:

int ressourceId;
int tv_number = 50;
TextView[] tv = new TextView[tv_number];

for(int i = 0; i < tv_number; i++) {
    ressourceId = getResources().getIdentifier("tv" + (i + 1), "id", context.getPackageName());
    tv[i] = (TextView) myFragmentView.findViewById(ressourceId);
}
