[android-beginners] Add ListView to RelativeLayout
Hi there, I'm having trouble to add a listview to a relativelayout. Ok, not adding itself is the problem. I'm not able to fill it with my data. I receive my data from a query to a webservice where i get a list of books as response. In my listview i want to display just the title of these books. And there's the problem. If I'm trying it with listView.setAdapter(this, android.R.layout.simply_list_item1, listBook); I just get the id or value of those books. I also tried to achieve it with listAdapters but... I need a little guide for that. Or maybe I'm totally in the wrong direction and I need a class which extends listActivity with an EditView to generate my query and not a listView within a RelativeLayout ? I would be very grateful for any kind of help :) -- You received this message because you are subscribed to the Google Groups "Android Beginners" group. NEW!

[android-beginners] Enlarge/Shrink button size with onLongClick
Hi,
I'm going to create a custom keyboard app. One feature is, that an
user can resize the keys.
Currently I'm doing this by firstly creating a button, which can be
resized and letters can be entered. In the second step, the button
should be transformed into a key. Resizing is done by two buttons,
making by onClick the "Key-Button" bigger and smaller. But i think
it's very annoying to do 20 clicks if you want a 20 times bigger
button.
So i tried to use onLongClick, that if a resize button is pushed and
held, the "Key-Button" should be resized.
But my problem at the moment is, that the onLongClickListener-method
doesn't work properly. I tried it like this:
zoomin_button.setOnLongClickListener(new OnLongClickListener(){
public boolean onLongClick(View v){
int height = current_button.getHeight();
int width = current_button.getWidth();
boolean longclick = true;
while(longclick == true){
current_button.setHeight(height+2);
current_button.setWidth(width+2);
}
Toast.makeText(BApp.this, "Long Click",
Toast.LENGTH_SHORT).show();
return true;
}
});
If I do it like this, after a short time I get a message which says:
"Activity xy doesn't react".
While I tried it like:
zoomin_button.setOnLongClickListener(new OnLongClickListener(){
public boolean onLongClick(View v){
int height = current_button.getHeight();
int width = current_button.getWidth();
current_button.setHeight(height+2);
current_button.setWidth(width+2);
Toast.makeText(BApp.this, "Long Click",
Toast.LENGTH_SHORT).show();
return true;
}
});
The Toast shows up but the button isn't resized.
Okai. If you have any suggestion how this can be solved I would be
deeply grateful !
Thanks in advance !

[android-beginners] ArrayList items are missing
At the moment, I have two Activities (Activity A and B). At the Activity A I customize a button and pass it on Activity B via an intent. On Activity B I move the button somewhere on the screen. This will be done with other buttons. So I want to save some attributes of a button like height, width and alignment. I tried to save them in an ArrayList but everytime I access the ArrayList after changing back from Activity B to Activity A to create a second button, the ArrayList is empty. How could I achieve the ArrayList isn't loosing it's items ? I think the worst idea is, to make an Intent with that ArrayList sending it to Activity A.The List is getting bigger and bigger and I start to loose performance. Any suggestion how this can be solved ? I would be deeply grateful and thanks in advance ! -- You received this message because you are subscribed to the Google Groups "Android Beginners" group. NEW!

Thank you ! Static was the magic word.

[android-beginners] Button properties not set properly
After solving the problem with the invisible ArrayList, the next
problem occurred. Situation is still the same:
There are two Activities (Activity A and B). At Activity A I customize
a button and pass it on Activity B via an intent. On Activity B I move
the button somewhere on the screen. This
will be done with other buttons. On Activity B I also want to show the
old Buttons.
Thats the code:
if(keyList.isEmpty() == false){
for (iter = keyList.iterator(); iter.hasNext();){
Button k = (Button) iter.next();
Button ok = new Button(this);
ok.setHeight(k.getHeight());
Log.i("Button K", "Height: " + k.getHeight());
Log.i("Button OK", "Height: " + ok.getHeight());
ok.setWidth(k.getWidth());
ok.setText(k.getText());
ok.layout(k.getLeft(), k.getTop(),
k.getRight(), k.getBottom
());
ok.setVisibility(1);
rel_layout.removeView(ok);
rel_layout.addView(ok);
}
But there are two problems:
1. The properties are not set properly
With
ok.setHeight(k.getHeight());
Log.i("Button K", "Height: " + k.getHeight());
Log.i("Button OK", "Height: " + ok.getHeight());
I get
Button K Height = 48
Button OK Height = 0
At my Activity it is set correctly but here...
2. As above mentioned, I want to move the Buttons and set them
somewhere on the screen (e.g. down right). But everytime I call
Acitvity B again, all Buttons are located at top left.
I thought it would be achieved with
ok.layout(k.getLeft(), k.getTop(), k.getRight(), k.getBottom());
But obviously not.
Any suggestion and hints how this could be solved would be
appreciated !

[android-beginners] Create soft keyboard dynamically
Hi, it's me again, with a new question. (I hope its not double posted, cause for the last one i got a "post rejected" mail) Ok, here's the Question: Is it possible to write an Softkeyboard without XML or is this the time i'll need it ? The idea is: I have an Arraylist with buttons which have a specific position in the layout, height, width, text etc. Those buttons should create my keyboard by converting them into keys. If this won't work, my second idea is, to write a XML-File out of Java. I wonder if one of these ideas are possible.

[android-beginners] How to save a file to res/raw ?
Hey,
After reading so many tutorials about how to read a file from res/raw,
i'm still wondering how i can write a file to res/raw.
At the moment I'm saving my file like this to the emulator:
FileOutputStream fos = null;
OutputStreamWriter osw = null;
try{
fos = openFileOutput(filename + ".xml", MODE_WORLD_READABLE);
osw = new OutputStreamWriter(fos);
... //some code
}
But the problem is, i need to read it from another class, which only
accepts xml - files.
I would be very glad if someone could help me.

[android-beginners] Re: How to save a file to res/raw ?
Thanks for your replies. That are bad news for me. Hm, if i cant't save them to res/raw directory, i still can write and read them to the local data store, can't i ? I mean can I access data/data//files/ ? -- You received this message because you are subscribed to the Google Groups "Android Beginners" group. NEW!

[android-beginners] Re: How to save a file to res/raw ?
Great. This is what I wanted to know :) But, there's the next question. I'm still trying to create a custom soft keyboard. Therefore I need that xml - file. But how do I load my custom layout file into that ? I mean, the constructor only accepts an int ID. Like mQwertyKeyboard = new custom_keyboard(this, R.xml.qwert); If I try to put my xml file via FileReader or the like to the constructor, I get an error. Is there a way I can generate an ID or use my xml file ? -- You received this message because you are subscribed to the Google Groups "Android Beginners" group. NEW!

[android-beginners] Re: How to save a file to res/raw ?
hm, but if i can't write a file to res/layout/ , how can i load my layout ? I think there's the same read-only restriction to res/layout as to res/ raw, isn't it ?

[android-beginners] Re: How to save a file to res/raw ?
I'm not sure if it's possible to rewrite the code in java. Looking up at the Doc, if there's a way to create a keyboard without any xml I found this one: >> public Keyboard (Context context, int layoutTemplateResId, CharSequence >> characters, int columns, int horizontalPadding) but, >int layoutTemplateResId< says (if I understand aright), I'll need an ID again, like the one in >> mQwertyKeyboard = new custom_keyboard(this, R.xml.qwert); Although it creates an empty Keyboard. Very confusing... -- You received this message because you are subscribed to the Google Groups "Android Beginners" group. NEW!

Hm, good idea. I don't know if it's possible. But I'll give it a try.
