Android :: Displaying XML-based Layout / Adding Text Dynamically

Sep 12, 2009

I have a LinearLayout defined in XML that I want to use repeatedly to display elements of a list. The XML-layout looks like this:

<?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"
android:background="@drawable/background"
android:paddingBottom="5px">

<TextView
android:id="@+id/destination"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="22dp"
android:text="@string/test_destination"
android:paddingLeft="5px"/>

<TextView
android:id="@+id/date"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="15dp"
android:text="@string/test_date"
android:paddingLeft="5px"/>

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/info"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingLeft="5px"
android:paddingTop="10px" >

I gather information about certain events from a webpage, and then I want to display all events in a list using the above layout for each event. My current approach is to have a LinearLayout as parent and then adding each event as a row.

Problem number one is to add the layout to each event (the number of events is varying). I.e., I want to dynamically inflate this layout for each event. I also don't want the text to be hard coded into the layout (as above) but added at runtime. I don't know how to do this. I have tried something like the following without any success.

LinearLayout eventView = (LinearLayout) findViewById(R.layout.event);
parentView.addView(eventView);


Problem number two is then to add these layouts to the parent view group and display it on the screen. When I try to do this using parent.addView(child), the program crashes at runtime and I can't figure out why.

It's kind of hard to describe the specific problem, since I'm new to GUI-programming on Android and I'm sort of programming by trial and error right now. Anyway, if you are able to help me with some of the problems it would be greatly appreciated. Linus

EDIT:
The problem now is adding text dynamically to the TextViews. I try this:

TextView dest = (TextView) findViewById(R.id.destination);dest.setText("myText");

only to discover that dest is null. Any ideas why and how to fix this?

EDIT 2:
I have narrowed the problem even more, but I really don't understand its nature. This is the trouble-method: Code...
it somehow works (even though the events are displayed in reverse order). Anyone knows what's going on here?

Android :: Is There Setting Text To Display Layout

Nov 18, 2010

simple question. In a class, if I wanted to set the text to the text value of a string I have, what is the code for that?

I have: TextView textView = (TextView) findViewById(R.string.noFaceFive); textView.setText(textView);

but setText says : The method setText(CharSequence) in the type TextView is not applicable for the arguments (TextView)

is there a set Text to display the text of a string? Serious mind fart on my part.

Android :: Dynamically Adding A View To Activity Layout

Aug 18, 2010

I have a custom view (an extension of a TextView) that I want to dynamically add to my Layout (don't want to include it in the main.xml file).

The book says to fetch the RelativeLayout using findViewById() in my java code then create a new instance of my custom view, then use addView on the RelativeLayout to add the new view.

I'm not getting any errors, but when I click my button to add the new view, nothing is happening (view isn't being added). Do I need to set additional properties on my custom view (layout width, layout height for example) in order for it to be shown?

Adding code

Android - How To Run Code Depending On Simultaneous Hard Key Press

Mar 19, 2014

I am trying to implement a functionality when i press the VOLUME DOWN and POWER BUTTON simultaneously; i must be able to run a method code inside my Activity.

public boolean onKeyUp(int keyCode, KeyEvent event)
{
}

From my initial search; it seems that only one such key press event is acknowledged at a time in Android usng the onKeyUp method. Is it true?

In my Android phone, on simultaneously pressing POWER BUTTON as well as MENU BUTTON i am able to capture a screen shot.

Does this feature not acknowledge simultaneous key presses?

Android : Changing Text Value Of A Textview Dynamically

Nov 9, 2010

I have a textview in my XML layout file, but when I try to change its text value with code pragmatically (dynamically, depending on which button the user clicks) then the text of the textview doesn't change.

This is the code that I tried:

TextView userText = (TextView) findViewById(R.id.User);

userText.setText(bundle.getString("user"));

In debug mode, I can see that usertext has the changed text, but the change doesn't appear on my mobile window... I don't know why.

EDIT: SOLVED! it was a problem with my relative layout, text is out of the window!

Android :: Dynamically Setting Links To Text In Strings.xml?

Feb 11, 2010

I'm trying to make an app with localisation built in, but I want a way that I can create a web link within the text, the URL being defined elsewhere (for ease of maintenance).

So, I have my links in res/values/strings.xml code...
But this didn't work either.

So, I'd like to know if there's a way of dynamically adding multiple URLs to different sections of the same text which will link to web content?
