[android help] How to align view elements in Relativelayout dynamically through code in Android?

layout.addView(cb1);     

lp.addRule(RelativeLayout.BELOW,cb1.getId());
cb2.setLayoutParams(lp);        
layout.addView(cb2);

lp.addRule(RelativeLayout.BELOW,cb2.getId());
cb3.setLayoutParams(lp);
layout.addView(cb3);

Thanks man this helped me a lot

I guess you are wrong at the point that you are using "lp" as the layout parameters for both cb2 and cb3(you can't add the same rule "RelativeLayout.BELOW" to same layoutparameters object "lp" again and again). Use lp for cb2 and lp2 for cb3 and create like this

        RelativeLayout layout = new RelativeLayout(this);

CheckBox cb1 = new CheckBox(this);
cb1.setId(1);
cb1.setText("A");

CheckBox cb2 = new CheckBox(this);
cb2.setId(2);
cb2.setText("B");

CheckBox cb3 = new CheckBox(this);
cb3.setId(3);
cb3.setText("C");

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT);
layout.setLayoutParams(lp);

layout.addView(cb1);     

lp.addRule(RelativeLayout.BELOW,cb1.getId());
cb2.setLayoutParams(lp);        
layout.addView(cb2);

RelativeLayout.LayoutParams lp2 = new RelativeLayout.LayoutParams(
        RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);//important

lp2.addRule(RelativeLayout.BELOW,cb2.getId());//important
cb3.setLayoutParams(lp2);//important
layout.addView(cb3);

I think this will work.

[android help] Storing and accessing large tables of static information

I am writing an Android application that reads data from legacy devices, and presents it to the user. Much of this data consists of 16-bit enumerations that represent things like device information, status, errors, etc... There are over 100 of these enumerations.

In the past, the user would have to look up the returned value in a large binder of tables. For example, let's say the device returns an error as 0xFE04. There's some row in some table like this...

+--------+-------------------+------------------+----------+--------------------+
|  Code  | Short Description | Long Description | Solution | Alternate Solution |
+--------+-------------------+------------------+----------+--------------------+
| 0xFE04 | blah              | blahblah         | blah     | blahblah           |
+--------+-------------------+------------------+----------+--------------------+

How can I store these tables in code so that I can return all this information to the user efficiently & effectively.

This may have to be ported in the future for iOS or even windows, so a more language-independent solution is preferred.

[android help] On Google TV How do I make Fullscreen Activity hide title and button properly?

Tell me more ×

Stack Overflow is a question and answer site for professional and enthusiast programmers. It's 100% free, no registration required.

It would seem that the Fullscreen Activity Demo/Template does not behave the same on Google TV with the way Status/Navigation/Action bar are handled. Note: to make the default template work on Honeycomb I had to make a slight change to the provided SystemUiHiderHoneycomb class (details) Question: Should the Template work properly? (I think yes). Is there a good way of fixing it without special handling for Google TV detection? What's a good way of achieving the same result of hiding the title at the top and the button at the bottom? Steps to reproduce: Create new application via Android Tools wizard Use Fullscreen Activity as first and only activity perform code modification to SystemUiHiderHoneycomb class (details) I tested this on a Google TV emulator and on a real device with the same result. (I also tested it without the change in step 3). asked 3 hours ago

	How to convert BLOB to string? Direct conversion is not possible without using some UDF, but you can extract text using SUBSTRING function: What is the datatype of the column you are getting the error on (from what you say I think this is the URL column)? Sounds like it is of type BLOB which is a representation of an image but not a string answered Aug 22 '11 at 15:52

[android help] How can I detect current device is Android Tablet?

Your Galaxy Tab is running Honeycomb or higher, which means that the old Options Menu has been deprecated in favor of Action Bar. That having been said, there's still a menu icon in the title bar (a square with a slash through it in Honeycomb and three square dots in Jelly Bean). If your user clicks that, they get your standard options menu (without menu item icons, however).

The alternative is to run ActionBar Sherlock to give your apps action bars, regardless of OS version.

If you insist on doing your own branching based on OS version, try this:

int sdk = android.os.Build.VERSION.SDK_INT;

if(sdk < android.os.Build.VERSION_CODES.HONEYCOMB)
{
    // Gingerbread and earlier
}
else
{
    // Honeycomb and later
}

[android help] HTC One X+ Home Sence Launcher won't let me clear defaults programmatically

I want to show Settings->Applications->Manage Applications-> home launcher application ->'Clear Defaults' programmatically in my application.This works fine in all devices except HTC One X+.

In HTC One X+, 'Home Sence' application is set as default home launcher.When i tried to set my application as home launcher this shows Resolver Dialog too.

In my application i want to clear the default settings of current home launcher application and set mine as home launcher.So,I tried this code

 Intent intent = new Intent();
    final int apiLevel = Build.VERSION.SDK_INT;
    if (apiLevel >= 9) { // above 2.3
         intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
         Uri uri = Uri.fromParts("package", packageName, null);
         intent.setData(uri);
   } else { 
        // below 2.3
         String appPkgName = (apiLevel == 8 ? "pkg" : "com.android.settings.ApplicationPkgName");
         intent.setAction(Intent.ACTION_VIEW);
         intent.setClassName(APP_DETAILS_PACKAGE_NAME,   APP_DETAILS_CLASS_NAME);
         intent.putExtra(appPkgName, packageName);
   }
   this.startActivity(intent);

But it won't let me show the 'Clear Defaults' of HTC Sence.It works for any other application on this device.What is the problem here? Why 'HTC Sence' won't let me to clear defaults?How can i fix this?

Thanks in Advance

I am trying to make an android app that will create some records in simple text files such that a computer can access those file. I think I understand the process of creating and writing files internally but I can't find these files with the computer when I connect it through USB or an app such as AirDroid. My initial intention was to put the file in a folder (maybe the root folder) which would allow me to grab that information from my personal computer. Is such thing even possible? If it is not, is there an alternative way of accessing the files created by my app? Thanks for your help. asked 6 mins ago

[android help] Android Search Using Fragments

Tell me more ×

Stack Overflow is a question and answer site for professional and enthusiast programmers. It's 100% free, no registration required.

I need to do an android search using fragments and have been looking at this: Android search with Fragments I have a couple of questions, however, regarding the 1st answer. I do not want a new page to pop up; I want the search results to be populated within a listview of the current fragment I am within. Is that possible? I'm not sure what code to write after: /** * Performs a search and passes the results to the container * Activity that holds your Fragments. */ public void doMySearch(String query) { // TODO: implement this } How do I pass my results to a 'container activity' that holds my fragments? Would that be my MainActivity (that's where the code of all my fragments is located)? asked 49 mins ago

'Container Activity' doesn't specifically your MainActivity as this is the name a lot of devs and example code gives to their landing/home activity. 'Container Activity' refers to the Activity to which your ListView (ListFragment?) and Search Fragment belong. To post the results (via your TODO code), get the parent Activity (getActivity()) and implement a method on the parent Activity that gets the fragment with the ListView and passes the data to it. You may want to have a method on the ListView that handles this rather than putting it on the Activity. (I like to think of a parent Activity as a delegator) answered 5 mins ago

In Go Launcher, you had to do it from their menu dock that came up when you swiped up from the bottom. See if any of those help while waiting for someone with experience with this launcher to answer.

[android help] gridView vertical separator not visible in android

I generated a custom grid view, by passing to my adapter an ArrayList with Arrays of Strings.

Everything is working fine, my gridView is generated as I want (every String Array represents a column in my gridView).

The only problem is, that I can not see vertical separators in the gridview, only the horizontal ones are visible. I really need the vertical separators as well. Please help me with this.

Here is my xml

    android:id="@+id/gridview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:columnWidth="130dp"
    android:horizontalSpacing="10dp"
    android:verticalSpacing="10dp"
    android:gravity="center"
    android:stretchMode="columnWidth"/>

Here is my code

ArrayList list = new ArrayList();
String [] id = {"IDs", "S001","S002","S003","S004","S005","S006","S007"};
String [] name = {"NAMES", "Rohit","Rahul","Ravi","Amit","Arun","Anil","Kashif"};
String [] products = {"Products", "Bear","Tea","Apple","Food","Color","Program","Telephone"};
String [] stuff = {"Stuffs", "Stuff_01","Stuff_02","Stuff_03","Stuff_04","Stuff_05","Stuff_06","Stuff_07"};
list.add(id);
list.add(name);
list.add(products);
list.add(stuff);

gridview = (GridView) findViewById(R.id.gridview);  
gridview.setAdapter(new DataAdapter(this, list));

My Custom Adapter

public class DataAdapter extends BaseAdapter {

Context mContext;
private ArrayList list;
private LayoutInflater mInflater;
private ArrayList layouts = new ArrayList();

public DataAdapter(Context c, ArrayList myList)
{
    mContext=c;
    mInflater = LayoutInflater.from(c);

    list = myList;
}

@Override
public int getCount()
{
    return list.get(0).length;
}

@Override
public Object getItem(int position)
{
    return layouts.get(position);
}

@Override
public long getItemId(int position)
{
    return position;
}


@Override
public View getView(int position, View convertView, ViewGroup parent)
{    
    LinearLayout view;

    if (convertView == null) {
        view = new LinearLayout(mContext);

        for (int i = 0; i < list.size(); i++) {

            TextView tv = new TextView(mContext);
            tv.setLayoutParams(new GridView.LayoutParams(80, 30));

            view.addView(tv);   
        }

        layouts.add(position, view);
    }
    else {
        view = (LinearLayout) convertView;
    }

    for (int i = 0; i < view.getChildCount(); i++) {
        TextView tv = (TextView) view.getChildAt(i);
        tv.setText(list.get(i)[position]);
    }

    view.setBackgroundColor(Color.BLUE);

    return view;
}

Frustrated with backup / root of android phone - Samsung galaxy grand - pls help

Hi Experts,
I have been reading and reading and reading threads and posts from last so many days to make sure I understand before rooting my newly purchased Samsung galaxy grand I9082.

However even after trying my best I am still confused. Pls help me clarify following questions.

Pls see my phone's existing firmware / OS status: Refer link below or attached screenshot

Q 1. I trust my above phone is right now having latest firmware from Samsung? How do i root without downgrading my firmware?
(Many forum posts seems to suggest rooting process but it downgrades firmware i believe)

Q2. After rooting can i continue to use Kies?

Q3. After rooting can i continue to update Samsung future updates?

Q4. What’s best effective backup method before rooting?

Q5. Will it be possible to safely revert back to position right now after rooting?

Pls address my questions in sufficient detail so that I can realize my dream of rooted android phone.

Thank you in advance for your time.
