Android :: Unable To Select Children (textview) Of TableRow Programmatically / Fix It?
Nov 2, 2010
I'm trying to access the textviews (for starters, eventually replace with imageviews etc) which are stored in the tablerows in the code below.
The line beginning 'log.d' was the part I was working on, trying to get it to print out the contents of the 2nd text view in the first row, but I can only get as far as selecting the tablerow using "getChildAt(i)".
Trying "getChildAt(0).getChildAt(1)" doesn't select the textview as I would have expected it to; says that it's a View and as such, doesn't have this method - though unless I'm mistaken, aren't tablerows ViewGroups, which do have this method? code...

I'm making a image gallery with infinite vertical and horizontal scrolling. I put images inside a ListView to make a column, and put the ListViews inside a TableRow. However, it seems that child views of TableRow is not selectable and as a result I can't select the images in my ListView (easily). Is there a way to pass the events down to child views of TableRow so they can be selectable?

I have an Activity in which I have a TableLayout. I fill the table with TableRows in which I display TextViews. Imagine this as a classical table with text content. After the loop is finished I want to read all the heights in pixels of all the TextView in this table. I do this with getHeight(). The problem I have now is that ALL the values are 0 (zero) pixels. Even though I have text in the TextViews. The odd thing about this is, if I read the height of the exact same TextViews in an OnClickListener () then I do get the real height of the elements. Why is that so? I mean, nothing has changed in the height of those elements in the time between filling the table and firing the OnClickListener(). I really need to be able to get the height of the TextViews right after I filled the table. To get the heights upon a click is too late already for what I want to do.

I am using Tablerow+TextView to make a simple view for blog posts and their replies. In each TableRow I put a TextView in. Now I have two issues:
The text which is longer than the screen won't automatically wrap up to be multi-line. Is it by design of TableRow? I've already set tr_content.setSingleLine(false); [update]
This has been addressed, I think I should change Fill_parent to be Wrap_content in
CODE:............
The Table won't scroll like ListView. My rows are more than the screen size. I expect the table could be scrolled down for viewing just like ListView. Is that possible?
Here is my code:

Is there any way to programmatically select a ListView item such that when using a simple_list_item_single_choice layout, it lights up the radio button? Because setSelection(position) does not seem to have this effect.

I have a TextView which is inside a LinearLayout which is in the child position of an ExpandableListView. Without assigning a color state selector to the text view, the following behavior is observed:Text unselected - text paints as white Text selected - text paints as black.If I add a color state selector with a call to text.setTextColor(R.color.textcolorstatelist) then the following behavior is observed:Text unselected - text paints as black Text selected - text paints as black.I tried two versions of textcolorstatelist.xml and both produced the results above.

I have different elements in my layout: Buttons, RadioButtons, EditText, a ListView and I have made a RelativeLayout that is clickable and starts a new intent. Everything works ok except that I can't select that element with the trackball. Is there any way to achieve this?

I have a LinearLayout with two views in it, an ImageView and a TextView. The ImageView resource is actually pulled from an xml selector in res/drawable so that it shows one of two drawables, call them selected.png and unselected.png. When I call LinearLayout.setSelect(false) the unselected.png drawable appears and the text is drawn in white. When I call LinearLayout.setSelect(true) the selected.png drawable appears and the text is drawn in black. How can I change this behavior of the TextView so that it always draws in white?

I am desperately trying to set TextView attributes of cells within a table programmatically but can't get this to work! Whenever I set layout properties, the field will simply not appear (but not give any error or exception). I boilded this down to this simple example:
CODE:.......
This will show three fields, but when you uncomment the five commented line, then NOTHING will appear. Why is that so? Why does setting layout parameters cause my TextView's to not appear? I'm stuck! What am I missing?
Here's the manifest, if some kind soul quickly wants to try this out:

I can use android:gravity="bottom|center_horizontal" in xml on a textview to get my desired results but I need to do this programmatically.
My textview is inside a tablerow if that matters in a relativelayout.
I have tried:
CODE:........
But if I understand that correctly, that would apply it to the tablerow? not the textview?

I'm currently using something like: TextView.SetBackgroundColor(Color.WHITE); in my java code. I'd like to be able to add some transparancy to the textview through the java... This is easy to do in the XML via #AARRGGBB format, but I have not found a way to accomplish this programmatically.

Anywho, I want to go into Gmail, compose a new email, and be able to select contacts (or even have the app provide a look-ahead list based on what I type). This is exactly how the Gmail app for my Blackberry 8830 worked so I don't understand why there seems to be less functionality no an Android phone. In any case, it seems that no matter what, all I can do is manually type in email addresses. Also, I know I can go into Contacts (People) and select a person's email. This brings up a menu option to email using Gmail or my Exchange email account. This in't good enough because all I can do is open a new email to one person this way. What if I want to email 10 people!?

So everyone hates the Sprint Navigation because it constantly runs and drains your battery... agreed... but I don't really feel like rooting my phone if I don't have to so here's the dilemma and question.
Dilemma: Sprint GPS seems to be the default GPS to for the web broswer to use. Because of this an app like Zombie Run's Multiplayer, cannot communicate with GPS satellite's it's set up for because the phone is connecting with Telenav (hypothesis, but Verizon phones locate gps and sprint does not)
"Aboutebug" in a web browser only gives the option to use gps or not.
Is there anyway to select which GPS program you want the web browser (or phone in general) to use?

I would like change the width of a Horizontal Progressbar programmatically (initial size is set in XML using RelativeLayout...but I would like to dynamically change it based on certain values).
I have tried setMinimumWidth(50) in my code, but that did not make a difference. I have also tried setting 'android:layout_width="wrap_content", but that did not work either.
Here is my XML:

I'm unable to change the layout_gravity of a Button programmatically, does anybody know how to do this?The gravity attribute is easily changed using Button.gravity(), Ie it changes the gravity of the text inside the button I cannot change the gravity of the button itself. I also cannot seem to find this in any of the layout params contructors.

I see a strange problem when I try to set a TextView, instead of a layout file via setContentView.
Case 1: i.e. if I do the following, it works fine...
TextView tv = new TextView(this); tv.setText("Hello World"); setContentView(tv);
Everything is OK.
Case 2: But suppose I have a main.xml file with a TextView in it and I try the following:
=========== View tv = findViewById(R.id.textview); setContentView(tv); =========== I get a Force Close with the below error
09-27 00:08:26.620: ERROR/AndroidRuntime(1595): Caused by: android.content.res.Resources$NotFoundException: Resource ID #0x7f050001 type #0x12 is not valid 09-27 00:08:26.620: ERROR/AndroidRuntime(1595): at android.content.res.Resources.loadXmlResourceParser(Resources.java: 1801) 09-27 00:08:26.620: ERROR/AndroidRuntime(1595): at android.content.res.Resources.getLayout(Resources.java:685) 09-27 00:08:26.620: ERROR/AndroidRuntime(1595): at android.view.LayoutInflater.inflate(LayoutInflater.java:318) 09-27 00:08:26.620: ERROR/AndroidRuntime(1595): at android.view.LayoutInflater.inflate(LayoutInflater.java:276) 09-27 00:08:26.620: ERROR/AndroidRuntime(1595): at com.android.myhelloworld.SimpleActivity.onCreate(SimpleActivity.java: 22)
Case 3: I even tried to inflate the xml and set the view but even that resulted in a force close.
Am I missing something here ?

I have couple of contacts which have multiple numbers so I added all of those under a single name Now, when I try to message those names, starting from "new message", somehow typing the names in "To" bar does not thrown those names. Instead, it shows some weird number (e.g. 2229 etc) when typing those names Net result, the contacts are not accessible from messaging application. Now I need to go to the contacts to text them.

I've got a Nexus S running 4.0.4 and the emulator running 4.1.2. I'm experiencing the exact same thing on both:
I have two exchange accounts configured in the EMAIL application. When I view the unified inbox and compose a new email, I am unable to select the non-default FROM address (clicking the FROM address does nothing). In order to send an email from the non-default, I have to enter the inbox for that account THEN compose a new email - requires several more clicks than necessary.
I have asked several friends and some say they do have this option - however they are all on carrier customized roms.

With the XML layout shown below, I have some views wrapped in a GestureOverlayView. As shown below, my first row is blended with the second row, as-if the first row is transposed right on top of the second. Now when I take the GestureOverlayView out of the code and leave everything else as-is, my table looks fine - the rows are separate and not on top of each other..........

i'm in final stage of writing my custom widget (quite similar to Home's sliding panel). it works quite well except one thing: i have some problems with positioning it in FrameLayout (see 3 rightPanel* Panels in main.xml in attached eclipse project).basically i don't like the idea i'm using there: setting layout_marginTop in panelHandle children.

Is there a way to get all the children views of a layout, from the Java code so that I can loop through them and set an attribute? Specifically, I'd like to set the "layout_width" based on the screen size. Since this "layout_width" would be the same for all the views, I'd prefer to loop through instead of calling each individual View separately by their id. The following is my main.xml:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content">
<LinearLayout android:id="@+id/myRow1" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1"> <TextView android:text="1" android:layout_width="wrap_content"
android:layout_height="50dip" android:layout_weight="1"/>
<TextView android:text="2" android:layout_width="wrap_content"
android:layout_height="50dip" android:layout_weight="1"/>
<TextView android:text="3" android:layout_width="wrap_content"
android:layout_height="50dip" android:layout_weight="1"/>
<TextView android:text="4" android:layout_width="wrap_content"
android:layout_height="50dip" android:layout_weight="1"/>
<TextView android:text="5" android:layout_width="wrap_content"
android:layout_height="50dip" android:layout_weight="1"/>
<TextView android:text="6" android:layout_width="wrap_content"
android:layout_height="50dip" android:layout_weight="1"/>
</LinearLayout> </LinearLayout>
