How i can fit to all devices. Can anyone help?? Thanks in advance.

There are couple of possibilities:
use different xml files for different sizes of screen -> check here http://developer.android.com/guide/practices/screens_support.html
you may use scrollview -> http://developer.android.com/reference/android/widget/ScrollView.html
or simply make your layout fit to the smallest screen size you like to support and then just have "a little" unused space on the larger screens.
It really depends on what you need. Probably the most compatible and advanced solution would be 1.
BUT be aware of the fact that EVERY change on the screen layout has to be duplicated for each xml file following this route!

create xml for each device separately. follow this
second way:
create a parent LinearLayout and pass it to the following method
public static boolean isTabletPC(Context context) {
Display display = ((WindowManager) context
.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
if (display.getWidth() >= 1200) {
isTabletPC = true;
return isTabletPC;
} else {
isTabletPC = false;
return isTabletPC;
}
}
public static void fixUiDeviceDependencies(
Activity act, LinearLayout llParent) {
if (Utilities.isTabletPC(act)) {
Display display = ((WindowManager) act
.getSystemService(Context.WINDOW_SERVICE))
.getDefaultDisplay();
LayoutParams params = (LayoutParams) llParent
.getLayoutParams();
params.width = display.getWidth() / 2;
llParent.setLayoutParams(params);
}
}

Can anyone help please? When click on the quiz button the application will close. I want it to go to quiz page which called HomeScreen.java

looks good to me, did u declare the second activity in the manifest file? :
<activity android:name="HomeScreen"/>
If that doesn't work, use some break points and the debugger, hope it helps.

But i want the images to come like a stack.. Not exactly overlapped. Refer this
Can anyone help me achieve this?

This is a link with your solution https://github.com/Diolor/Swipecards
Incase you use custom ArrayAdaper on inflating layout this is the code that worked for me
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.swipe_item, parent, false);

show EditText on condition

Right now I have an idea for a project and I would like to know if anyone can help me on the same logic.
As such I need to create or generate a number of EditText according to amount you enter, ie, to select or enter a number such as 5, show me 5 EditText layout for type 5 values. They know that the form could accomplish this? Any ideas please?
I guess it must be a way to do it with a loop, but not like carrying this calculation Java to XML. Thank you.

Here is an example of generating EditText items based on the number you enter. You can ignore the scrollview in the layout file I just put it in case someone added a lot of EditText items that would go off the screen.

if (container.getChildCount() > 0) {
container.removeAllViews();
}

addEditText(container);
}

Using getFragmentManager on a ListActivity

I just want to know if this is possible since first. I have created a custom listView based on the tutorial I read from Sai Geetha. Well it works perfectly on my app except that it needs to extend ListActivity instead of FragmentActivity. Now I'm having a hard time configuring and adding a dialog for this since I need to apply a fragment dialog and I can't use the getFragmentManager() since I'm not working with the FragmentActivity. Is there's another way I can do to work on this without sacrificing the ListActivity? Thanks!
Here's my code so far
XML:
conversation_list_view

You can use ListFragment inside FragmentActivity instead of using a ListActivity.

prevent result from shown unless click the button

hi i want to show the result in edittext 2 only after click the convert button

here is the xml
<?xml version="1.0" encoding="utf-8"?>

</LinearLayout>

You can do the following to hide txt2 when you first create the activity:
txt2.setVisibility(View.GONE);
Then in the click handler for the convert button:
txt2.setVisibility(View.VISIBLE);
In the click handler for the clear button, presumably you would want to make it GONE again.
Regarding the problem of the clear button being off the screen: wrap your LinearLayout in a ScrollView (making the ScrollView the top view of the hierarchy with a single LinearLayout child). That way the user can scroll down to see all the content of your layout. You need to change the height of the LinearLayout to wrap_content:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#cad1d9"
>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
. . .
</LinearLayout
</ScrollView>
