android TextView setText not working
android, textview
Solution
For future reference, I had multiple fragments, one for each tab in my ViewPager. One TextView had the same `id` in two fragments and that created a conflict. I didn't realize I had the same `id` so everything seemed fine, no error message, but the text simply didn't change. Therefore I'd recommend using unique names for the `id`.
Problem
I know there are a lot of similar threads but I've gone through them and still can't figure out the problem. My program reaches the Handler but it always returns the catch exception "Message isn't handled." I declared the TextView `private TextView chatbox;` Under onCreate I have: ``` public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); setUpViews(); setUpListener(); } ``` where setUpViews() snippet looks like: ``` private void setUpViews() { chatbox = (TextView) findViewById(R.id.chatbox); } ``` Handler: ``` public Handler mHandler = new Handler(Looper.getMainLooper()){ @Override public void handleMessage(Message msg){ try{ chatbox.setText("Got it!"); }catch(Exception e){ Log.i("MYLOG", "Message was not handled."); } } }; ``` Snippet in main.xml file: ``` <TextView android:id="@+id/chatbox" android:layout_width="200dp" android:layout_height="200dp" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:textAppearance="?android:attr/textAppearanceLarge" /> ```
