Android :: FindViewByID - Get View Of A TextView Through A Listener Of Another UI Element?
Sep 9, 2010
This is going to be a bit lame question. I have the following code:
CODE:.....
I have a TextView in my xml layout file. I'd like to get it and change my text when I click this button.
But I can't get it (the TextView) unless I make it as a value of a static member of this class and pass it to the constructor. I believe I am missing a big point here, so i'd be very thankful if you could explain how this is meant to be done ?

Trying to have a ListView (scrollable list) of rows made of two TextViews. I have a list of items from a database that I want to populating into the LinearLayout->ListView->TextView but can't get to the id...
Layout somewhat like this instructional link, but have backed away from RelativeLayout and using LinearLayout to get it working. Not even worried about how it looks yet; just can't get it wired together yet.

Have two XML files (very abbreviated details below)
CODE:...........
I have an ArrayAdapter where I inflate the stuffView. My thinking and understanding of other examples is it's not inflated (this nested stuffView) until I purposely inflate it. That all works fine but when I do the findViewById it returns null and thus I can't setText().
epic Fail due to complete ignorance/newbieness on my part. Note: I've pored through what I can of Reto's book, especially a simliar example on Page 163 but fail fail fail...
Can some kind soul point me in the right direction?
Must I inflate this nested view? (Reto's example does). If so, what am I missing? I'm hoping someone can point me to a better example.
My code's probably too involved at this point to post and a bit proprietary.
CODE:........
A pojo called Thingy (not copying Thingy.java here - very simple)
The main class:
CODE:...........
So this code is in essence what I'm looking for help on; neutered the names to call it Thingy.... This sample isn't triggering the getView(). That's a secondary problem I have to sort out. More importantly, your help on the findViewById failure and if I've got the XML right would help a bunch.

I'm making out a few menus for my Android App and throughout there is a standard textview that is repeated 5 times, only changing the android:text tag each time, everything else is the same.There are a good number of properties on this and it feels very inefficient to be copy/pasting all these for each of the textviews.Is there a way I define the common properties just once and add them to each TextView element?

The layout xml is as below. I have a RelativeLayout, which contains a TextView. The OnClick listener is set on RelativeLayout. The RelativeLayout has a selector background. What I want is, when user clicks on the RelativeLayout, the background of the RelativeLayout should change, and the color of the text of the TextView should change too. Even though I set color selector for the TextView, only the selector on RelativeLayout works. The color selector on TextView doesn't work. How can I implement change of both RelativeLayout background and text color of TextView when user clicks the layout?

first of all: yes, I read all the other threads on this topic. And not only those from this site... (you see, i'm a little frustrated) Most of them come with the advice to use "android:id" instead of just "id" in the xml file. I did. From others, i learned, that View.findViewById works different than Activity.findViewById. I handled that, too.
in my location_layout.xml i use
<FrameLayout .... >
<some.package.MyCustomView ... />
<LinearLayout ... >
<TextView ...
android:id="@+id/txtLat" />.................

Does it exist an Android view equivalent to a "<select>" HTML input element ? In my application, user should fill a form. I know that ListView can display a list of elements but I think it's not relevant for a form.

What I´m trying to do is to create a list (using a list view) of items (which are views inflated from the same layout) what must be clickable. At first I thought that all I had to do was to add an onItemClickListener to the ListView so if the used clicked on any of the views that composed this Item the listener would react. Well, I was wrong. I´ve tried a lot of things, including setting focus and focusontouchmode off for each of the views that compose the item´s view but it still doesn´t work. Any tips here? Can I archive this result? Oh, also ... this list view is in a dialog and the listener is in the activity that builds the dialog.

Every time I put a TextView before an EditText element in a LinearLayout, the EditText does not show. When I don't, it does.
I've narrowed the problem down to the TextView's layout_width attribute. If I give it "wrap_content", it works, but doesn't "block" down, and it appears on the same line as the EditText.

I'm just beginning Android development, and I'm working to get a Custom list view with a checkbox working. I've created a base class that extends Activity, Created an Adapter and overrode the getView() method to add the checkbox to the list view. I'm assuming I need to do this because I need something equivalent to didSelectRowIndexAtPath from Obj C to update my model. Please let me know if there's an alternate way of doing this too Code...

I have a tab activity with three tabs and I want to display a listview in each tab. The list populates correctly, but for some reason I can not get the context menu or itemclicklistener to recognize gestures on the listviews. Anyone have any ideas why this might be? Below is my onCreate method: @Override public void onCreate(Bundle savedInstanceState) { super. onCreate (savedInstanceState);setContentView (R.layout.armory_header); TabHost mTabHost = getTabHost(); mTabHost.addTab (mTabHost. newTabSpec ("1"). setIndicator ("Weapons"). setContent (R.id.page1)); mTabHost.addTab (mTabHost.newTabSpec("2").setIndicator( "Armor" ).setContent(R.id.page2))TabHost.addTab(mTabHost.newTabSpec("3").setIndicator("Accessories"). setContent (R.id.page3)) ; weapons = (ListView) findViewById(R.id.weaponlist); registerFor ContextMenu(weapons) ;weapons.setOn ItemClickListener (new OnItemClickListener(){ @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {// TODO Auto-generated method stub listId = weapons.getId(); position = arg2; showDialog (DIALOG);armor = (ListView) findViewById (R.id.armorlist) ;register ForContext Menu(armor); armor.setOnItemClickListener(new OnItemClickListener(){ @Override public void onItem Click(AdapterView<?> arg0, View arg1, int arg2, long arg3) { // TODO Auto-generated method stub listId = armor.getId();position = arg2; showDialog(DIALOG);

I am developing an application in which the layout is independent of screen resolution.
Now my problem is that in TextView the textview layout does change itself when the resolution of screen changes but the size of text remain same.I want that when the resolution is high, according to that the text size should also adjust itself(i.e. text size should be changed).And similarly when resolution is low the text size should also shrink.But here when i reduce Y-AXIS to an extent the text vanishes.I will really appreciate any answer.
