I call on a few EditTexts via "instanceOf" because I don't necessarily know the exact names / ids of them. When I do this to get the text, it works just fine. But when I try to setText() based on the local instanceOf EditText, it won't display the string I am passing it. Oddly enough, when I setText and then Log the getText, it logs it correctly -- it just won't physically display it.
I also tested setting the visibility to View.INVISIBLE or View.GONE just to see if i can interact with it at all, and it doesn't do anything.
Here is the code snippet that sets the text then logs it:
LinearLayout mLayout = (LinearLayout) main_fields_holder.getChildAt(0);
LinearLayout mLayout2 = (LinearLayout) mLayout.getChildAt(0);
LinearLayout mLayout3 = (LinearLayout) mLayout2.getChildAt(1);
for(int i = 0; i < mLayout3.getChildCount(); i++){
View v = (View) mLayout3.getChildAt(i);
if (v instanceof EditText){
EditText e = (EditText) v;
e.setText("HELLO");
Log.v("USER TEXT", "Text is: " + e.getText().toString() + "!");
;
}
}
I should also mention that I do the same instanceOf method with button text and it won't display my setText either.
Is there some reason that a local instance of an editText (or button) cannot be manipulated?
By the way, the line Log.v("USER TEXT", "Text is: " + e.getText().toString() + "!"); DOES give me "HELLO!". I'm not even sure what that means for my problem.

I basically drill down into the layouts until i am at the linear layout that holds my editTexts.
Finally, here is the code snippets that inflate the layout:
main_fields_holder = (LinearLayout) findViewById(R.id.editItemFields);
view = LayoutInflater.from(getBaseContext()).inflate(R.layout.flight_fields,
null);
main_fields_holder.addView(view);
UPDATE: Just to test, I added this line to see if i can hard reference it by id:
EditText a = ((EditText)findViewById(R.id.flight_airline));
a.setText("HELLO");
And it STILL won't show up. Could the fact that I inflate the layout that holds these items have anything to do with it? Basically when a spinner item is selected, a layout is inflated and I try to set the Text of the items in that layout, but to no avail. Btw, I can also still trace out the value of the EditText after setting it, but the bugger just won't physically show up.
FYI I figured this out. For whatever reason, the app needed a moment to go through all of the functions that grab the information and set them, so I added a post handler:
handler.postDelayed(new Runnable() { public void run() { populateFields(item); } }, 500);
This 1/2 second wait allowed the information to be displayed properly. Thanks for everyone's answers
