Save and list contents in android

So I am creating an android application which opens the url entered by the user. Now each time an url is entered by the user, it needs to be save using the "save" button and the save list is seen using the "list" button.
This is my XML file:
<?xml version="1.0" encoding="utf-8"?>

My save button and list button is not able to save and list the URLs entered by the user.
What should I add?
Thanks

1) Not Saving:
Currently you are storing data statically inside your addArray object. Which gets cleared when you close app.
I think better to use persist data storage. So you can retrieve already stored websites when app re-launched. (Like browser manages history). Available storage options
2) Not showing list:
You need to pass your current list of urls (i.e. addArray variable) in bundle when starting Activity2 And read that list inside Activity2 onCreate. Find here.
ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, addArray);
show1.setAdapter(adapter);
You don't need this list adapter inside your main activity, You need to create it inside Activity2 and set this adapter in your listview.
I hope it will help you fix your issues.

Android - OnItemClickListener only *sometimes* not working

I have a ListView in one of my activities that I have bound to an ArrayList using a custom ArrayAdapter. I have set an OnItemClickListener to the ListView which should call a method that starts another activity. However, I find that when I click on the ListView items, it only sometimes works. Sometimes it will start the activity as it should; other times it seems to detect the click (the ripple effect appears on the list item) but does nothing; other times it doesn't even appear to detect the click (the ripple effect doesn't appear).
I've tried all the usual suggestions that I've come across: blocking descendants on the parent view item, setting clickable and focusable to false on all the components of the item views, setting isEnabled to return true in the custom adapter, etc, but the behavior remains the same. Any help appreciated. Here is the relevant code:
Activity containing the ListView:
public class ViewCollectionActivity extends AppCompatActivity {
private final String className = this.getClass().getSimpleName();
private CollectionHandler collectionHandler;
private Context context;
private ArrayList<Game> displayedCollection;
private GameCollectionAdapter collectionAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view_collection);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
context = this;
collectionHandler = CollectionHandler.getInstance(this);
TextView view = null;
if (collectionHandler.getDisplayedCollection().size() > 0) {
view = (TextView) findViewById(R.id.no_items_textview);
view.setVisibility(View.GONE);
}
String currentDate = collectionHandler.getDateLastSynchronised();
view = (TextView) findViewById(R.id.last_updated_textview);
view.setText("Last synchronised: " + currentDate + " Total games: " + String.valueOf(collectionHandler.getDisplayedCollection().size()));
collectionAdapter = collectionHandler.getCollectionAdapter();
ListView listView = (ListView) findViewById(R.id.collection_list_view);
listView.setAdapter(collectionAdapter);
AdapterView.OnItemClickListener collectionItemClickListener = new AdapterView.OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
launchGameDetailsActivity(position);
}
};
listView.setOnItemClickListener(collectionItemClickListener);
}
public void launchGameDetailsActivity(int position){
Log.d(className,"Starting lauchGameDetailsActivity method");
collectionHandler.setSelectedGame(position);
Intent intent = new Intent(this,ViewGameDetailsActivity.class);
startActivity(intent);
Log.d(className, "Ending lauchGameDetailsActivity method");
}
The XML for the activity:

The code for the custom adapter:
public class GameCollectionAdapter extends ArrayAdapter<Game> {
private ArrayList<Game> collection;
public GameCollectionAdapter(Context context, int resource, ArrayList<Game> collection){
super(context, resource, collection);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LinearLayout gameView = (LinearLayout) convertView;
LayoutInflater mInflater = LayoutInflater.from(getContext());
if (gameView == null) {
gameView = (LinearLayout) mInflater.inflate(R.layout.collection_item_view, null);
}
//Game game = collection.get(position);
Game game = super.getItem(position);
if (game != null) {
// This is how you obtain a reference to the TextViews.
// These TextViews are created in the XML files we defined.
TextView gameTitle = (TextView) gameView.findViewById(R.id.collection_item_name);
TextView numOfPlays = (TextView) gameView.findViewById(R.id.collection_item_plays);
ImageView thumbnail = (ImageView) gameView.findViewById(R.id.collection_item_image);
// check to see if each individual textview is null.
// if not, assign some text!
if (gameTitle != null){
gameTitle.setText(game.getTitle());
}
if (numOfPlays != null){
numOfPlays.setText("Plays: " + String.valueOf(game.getNumOfPlays()));
}
if (thumbnail != null){
thumbnail.setImageBitmap(game.getThumbnail());
}
}
// the view must be returned to our activity
return gameView;
}
#Override
public boolean isEnabled(int position) {
return true;
}
}

I discovered what was causing the problem: the way I had set up the array that backed the ListView meant that it was downloading and storing the Bitmaps for every element in the array all the time. Once I changed the implementation so that it only downloaded the images as the ListView required them, then that seemed to improve performance and the onClickListener started to work fine.
The implementation I used was the exact same one shown here:
http://developer.android.com/training/displaying-bitmaps/process-bitmap.html

I think the issue is due to the position of the item selection whenever you click you have an list position which is passed to your method launchGameDetailActivity(int position) check with log or toast on item click what all the position you are getting do the needful.
Here is my code try this like this if it helps.
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(RecipeClass.this, "Position is" + position, Toast.LENGTH_SHORT).show();
Intent intent = new Intent(RecipeClass.this, RecipeIngredients.class)
intent.putExtra("position", position);
startActivity(intent);
}
Check your arraylist value also whether they are not null.

How to add button and total dynamically?

How can I add a Total TextView inside ListView, as well as a Save Button under the ListView, dynamically?
Total is to be displayed similar to the following image. (note: not my data representation)
Activity A (Code Snippet)
long as=0; // for total
long bs=0;
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
// receive from B
switch (requestCode)
{
case 0:
result = data.getStringExtra("text"); // holds value (34,24)
name = data.getStringExtra("a"); // Project
as = as+Long.parseLong(result); // For total amount
Text = " " + name + " " + "RM" + result + ""; // display in listView
if (mClickedPosition == -1) {
//add new list
m_listItems.add(Text);
m_listBitmapItems.add(Global.img);
} else {
// edit listView value and image
m_listItems.set(mClickedPosition, Text);
m_listBitmapItems.set(mClickedPosition, Global.img);
}
adapter.notifyDataSetChanged();
listV.setAdapter(adapter);
break;
case 1: // Another name
result = data.getStringExtra("text");
name = data.getStringExtra("a");
description = data.getStringExtra("c");
bs = bs + Long.parseLong(result);
Log.d("FIRST", "result:" + result);
Text = " " + name + " " + "RM" + result + "";
if (mClickedPosition == -1)
{
m_listItems.add(Text);
} else {
m_listItems.set(mClickedPosition, Text);
}
adapter.notifyDataSetChanged();
listV.setAdapter(adapter);
break;
}
}
long samount = as + bs;
Toast.makeText(getActivity(), samount + "", Toast.LENGTH_LONG).show();
}
Activity A (Rendered Output)
Here I would like to add a Total TextView with value 58 (output as RM58), as well as a Save Button.
I am using the following xml files.
a.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:text="#string/text"
android:textSize="20sp" />
<ListView android:id="#+id/listView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
claims.xml (inside the listView)
<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<TextView android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:textAppearance="?android:attr/textAppearanceMedium" />
<ImageView android:id="#+id/imageView4"
android:layout_width="101dp"
android:layout_height="50dp" />
</AbsoluteLayout>
Thanks.

Add the following footer.xml file to res/layout http://developer.android.com/reference/android/widget/ListView.html
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent
android:orientation="vertical" >
// Format as you please
<TextView
android:id="#+id/tv"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:text="Total" />
</LinearLayout>
In your activity create and initialise the following variables.
LayoutInflater inflater = getLayoutInflater();
ViewGroup footer = (ViewGroup) inflater.inflate(R.layout.footer, listView,
false);
// You can add this when an item is added and remove it if the list is empty.
listView.addFooterView(footer, null, false);
tv = (TextView)footer.findViewById(R.id.tv);
// Update the text.
tv.append("t/"+ results.toString());
As mentioned in the comments, you can either use long total as a static class member and update it with the results value total+=results; taking care to reset the value to zero or decrement it if an item is removed from the list.
The other way is to loop through the items in your list, parsing the items to the object and getting the particular value of type long from each object and summing them as you go.
As you are now able to dynamically add your button, I'll add briefly for other users browsing, set the buttons visibility to GONE, so that the element does not displace the layout when it is not visible, HIDDEN makes the element not visible, but the space taken by the element affects the layout (and sometimes this is useful). Then the button visibility is dynamically changed to VISIBLE when an item is added to the list, and back to GONE when the list is cleared.
<Button
android:id="#+id/btn"
android:text="button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"/>

android ViewBinder with SimpleCursorAdapter

I would like to know if my solution using a ViewBinder is correct and suitable for my problem.
I have implememented a ContentProvider. The startactivity extends ListActivity and displays all the entries from a sqliteDB using my contentprovider. A Click on one of the entries in the listview starts another activity showing detailinformation about this entry:
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// Arzneimittel wurde durch Klick ausgewählt --> Detailansicht anzeigen
Intent intent = new Intent(this, MedikamenteDetailActivity.class);
intent.putExtra("_ID", id);
startActivity(intent);
}
This is the layout of the Detail-Activity:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/txtV_heading_statusinfo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/heading_status_info"
android:textAppearance="?android:attr/textAppearanceMedium" />
<ListView
android:id="#+id/datalist"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
<TextView
android:id="#+id/txtV_PhZnr"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/hint_phznr"
android:text="TextView" />
<TextView
android:id="#+id/txtV_Znr"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/znr"
android:text="TextView" />
<TextView
android:id="#+id/txtV_SName"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/sname"
android:text="Small Text"
android:textAppearance="?android:attr/textAppearanceSmall" />
<TextView
android:id="#+id/txtV_OName"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/oname"
android:text="Small Text"
android:textAppearance="?android:attr/textAppearanceSmall" />
<TextView
android:id="#+id/txtV_DoLC"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/dolc"
android:text="Small Text"
android:textAppearance="?android:attr/textAppearanceSmall" />
</LinearLayout>
The Detail - Activity Class:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_medikamente_detail);
_id = String.valueOf(getIntent().getExtras().getLong("_ID"));
mAdapter = new SimpleCursorAdapter(
this,
android.R.layout.simple_list_item_1,
null,
mFromColumns,
new int[]{android.R.id.text1},
0);
mCallbacks = this;
ListView mListView = (ListView) findViewById(R.id.datalist);
mAdapter.setViewBinder(new ViewBinder());
mListView.setAdapter(mAdapter);
getLoaderManager().initLoader(URL_LOADER, null, mCallbacks);
}
Within the activity I implemented an inner class for die ViewBinder:
private class ViewBinder implements SimpleCursorAdapter.ViewBinder {
#Override
public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
if(view.getId() == R.id.txtV_PhZnr) {
TextView phznr = (TextView)view;
phznr.setText(cursor.getString(columnIndex));
return true;
}
return false;
}
}
The binding works yet the data is bound to the listview. The other ViewElements stay empty. I can't really understand, why I set the Text of the view "R.id.txtV_PhZnr" and this text appears in the listview-element while the txtV_PhZnr stays empty.
Why do I need a listView-element. As this is a master-detail relationship, only one dataset can be shown in the detail view.
Thank you very much!

Why do I need a listView-element.
No, you do not need one. You can just load the data from your content provider and bind it to the TextViews that you have defined (the ones with ids txtV_xxx). Do this in the onLoadFinished() method.
I can't really understand, why I set the Text of the view "R.id.txtV_PhZnr" and this text appears in the listview-element while the txtV_PhZnr stays empty.
The view parameter passed to setViewValue() method of ViewBinder will only have one of the ids from the array of view ids that you instantiate the SimpleCursorAdapter with. In your case the view parameter will only have the id android.R.id.text1 since the passed-in array contains only this view id. Thus the body of if(view.getId() == R.id.txtV_PhZnr) {...} will never get executed. Hence txtV_PhZnr stays empty.
ViewBinder is used only when you need to alter the binding of data to views based on some condition. As far as your case goes, there is neither a need for a ListView nor a ViewBinder.

How to implement different behavior when the user clicks on different views in a ListView?

I a new to Android development, so this is kind of a basic question.
I would like to implement the same behavior as in the Contacts app. You have a ListView with a series of Contacts | phone icons. There you have one behavior when you click on the contact name, and another behavior when you click on the phone icon.
Here is my code.
Any help is much appreciated.
In summary, what is wrong with the approach
switch (v.getId()) {
case R.id.imageButtonAction:
Activity Class
public class CompaniesActivity extends Activity {
MyApp app;
ListView listCompanies;
Cursor cursor;
// Adapter and its corresponding FROM and TO statements. The number and sequence of the arguments must match in FROM / TO arguments.
SimpleCursorAdapter adapter;
static final String[] FROM = { MenuNavigationData.C_COMPANY, MenuNavigationData.C_DESCRIPTION};
static final int[] TO = { R.id.textCompany, R.id.textDescription }; //
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.companies);
//Gets a reference to the application
app = (MyApp) getApplication();
// Find your views
listCompanies = (ListView) findViewById(R.id.listCompanies);
addButton = (Button) findViewById(R.id.buttonAdd);
// Add actions to user interaction
listCompanies.setOnItemClickListener(new OnItemClickListener() {
#Override
**public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
switch (v.getId()) {
case R.id.imageButtonAction:
startActivity(new Intent(app, InstructionsActivity.class));
break;
default:
int i = adapter.getItemViewType(position);
startActivity(new Intent(app, EditMenuNavigationActivity.class));
break;
}**
}
});
}

Your onItemClick() callback receives both the specific view as well as its position (0-based), each of these can help you decide which view was clicked. The position is an index into the items you've added, and for more complicated scenarios you can view.setTag(Object o), and use getTag() to retrieve it from your callback.

New much better approach to solve this issue elegantly, and with less code!!!
With the following modifications, the User interface is much more responsive, no more double-clicking issues. :)
Much, much less code that simply works!
Modifications to Row xml
Insert a Linear layout to wrap both the
In this Linear layout, insert a tag named android:onClick="editCompanyClick"
This is the click handler that will be called in the Activity.

Modifications to Activity class
Remove the previous code
listCompanies.setOnItemClickListener(new OnItemClickListener() { #Override public void onItemClick(AdapterView arg0, View v, int position, long id) {
TextView company = (TextView) v.findViewById(R.id.textCompany);
ImageView dial = (ImageView) v.findViewById(R.id.imageButtonDTMFDial);
company.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(app, EditMenuNavigationActivity.class));
}
});
dial.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(app, InstructionsActivity.class));
}
});
}
Insert the code
public void dialClick(View v) {
startActivity(new Intent(app, InstructionsActivity.class));
}
public void editCompanyClick(View v) {
startActivity(new Intent(app, EditMenuNavigationActivity.class));

I finally found a solution.
This solves the issue. But adds another one. As expected, the ListView now behaves differently when the user clicks on different views(either TextView or ImageView).
But it seems unresponsive. I have to "double-click" in order to trigger either the company.setOnClick or dial.setOnClick. Any suggestions?
// Add actions to user interaction
listCompanies.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
TextView company = (TextView) v.findViewById(R.id.textCompany);
ImageView dial = (ImageView) v.findViewById(R.id.imageButtonDTMFDial);
company.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(app, EditMenuNavigationActivity.class));
}
});
dial.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(app, InstructionsActivity.class));
}
});
}
