Implement searchview on string type listview Android

I have a list of items and i want to start different activity on the basis of item, when i click it opens the correct activity but when i try to search list items from search view bar then it opens wrong activities.
listView = (ListView) findViewById(R.id.listView);
sv=(SearchView) findViewById(R.id.searchView1);
String[] values = new String[]{item1,item2,item3,item4,}
final ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_2, android.R.id.text1, values);
listView.setAdapter(adapter);
//linking from 1 item to other activity stars with if options//
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
if (position == 0) {
Intent myIntent = new Intent(view.getContext(), activity1.class);
startActivityForResult(myIntent,0);
}
if (position == 4) {
Intent myIntent = new Intent(view.getContext(), aactivity4.class);
startActivityForResult(myIntent,0);
}
}
});
sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String text) {
// TODO Auto-generated method stub
return false;
}
#Override
public boolean onQueryTextChange(String text) {
adapter.getFilter().filter(text);
return false;
}
});
I don't know much about coding but can any one solve my problem..

you are starting your activity on the basis of position but the position will be changed when you do the search because list will shrink and positions will change so to get data associated with the specified position in the list use getItemAtPosition
so changes conditions on the basis of data
if (parent.getItemAtPosition(position).equals("item1")) {
Intent myIntent = new Intent(view.getContext(), activity1.class);
startActivityForResult(myIntent,0);
}
else if (parent.getItemAtPosition(position).equals("item2")) { // use any item value here you want
Intent myIntent = new Intent(view.getContext(), aactivity4.class);
startActivityForResult(myIntent,0);
}
Note : you can use switch as well instead of long if or else-if ladder
e.g You have three string
item 1 position 0
item 2 position 1
item 3 position 2
after searching item 2 you have two values in your list close to your search
item 2 position 0
item 3 position 1
so position will change so don't use it instead use the data
Code
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent intent = null;
// global string to class
selectedValue = String.valueOf(parent.getItemAtPosition(position));
if (selectedValue.equals("item1")) {
// ^^^ use any item value here you want
Intent myIntent = new Intent(view.getContext(), activity1.class);
startActivityForResult(myIntent,0);
}
else if (selectedValue.equals("item2")) {
Intent myIntent = new Intent(view.getContext(), aactivity4.class);
startActivityForResult(myIntent,0);
}
}
});

How to get the selected item from this ListView?

I have a custom List view and I been trying to get to next screen if user clicks an item. It doesn't seem to work. I tried if else, switch. It works if I don't use either but that way, every item will go to the same screen. Any help would be appericiated.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.options_main);
OptionMainHeader option_list[] = new OptionMainHeader[]
{
new OptionMainHeader(R.drawable.clock_icon_48, "Helo"),
new OptionMainHeader(R.drawable.weather_cloudy, "Apple"),
new OptionMainHeader(R.drawable.weather_cloudy, "Mango"),
new OptionMainHeader(R.drawable.weather_cloudy, "Banana"),
};
OptionMainHeader1 adapter = new OptionMainHeader1(this, R.layout.option_main_header1, option_list);
listView1 = (ListView)findViewById(R.id.listView1);
View header = (View)getLayoutInflater().inflate(R.layout.option_main_header, null);
listView1.addHeaderView(header);
listView1.setAdapter(adapter);
listView1.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
int position = listView1.getSelectedItemPosition();
String selectedFromList =(String) (listView1.getItemAtPosition(position));
if (selectedFromList == "Helo"){
Intent CurrentWaitTime = new Intent(getApplicationContext(), go.class);
startActivity(CurrentWaitTime);
} else if (selectedFromList == "Apple"){
Intent Appointments = new Intent(getApplicationContext(), no.class);
startActivity(Appointments);
} else if (selectedFromList == "Mango"){
Intent Logout = new Intent(getApplicationContext(), go.class);
startActivity(Logout);
} else if (selectedFromList == "Banana"){
Intent Exit = new Intent(getApplicationContext(), low.class);
startActivity(Exit);
}
}
});
}

Try this
ListView1.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
TextView textView = (TextView) arg1;
String strText = textView.getText().toString();
if ("Helo".equals(strText)){
Intent CurrentWaitTime = new Intent(getApplicationContext(), go.class);
startActivity(CurrentWaitTime);
} else if ("Apple".equals(strText){
Intent Appointments = new Intent(getApplicationContext(), no.class);
startActivity(Appointments);
} etc, etc

You can't compare Strings with "==". What you need to do is use the method String.equals(String). Something like:
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String selectedFromList = option_list[position].getTHATSTRING();
if (selectedFromList.equals("Helo")){
Intent CurrentWaitTime = new Intent(getApplicationContext(), go.class);
startActivity(CurrentWaitTime);
} else if (selectedFromLis.equals("Apple")){
Intent Appointments = new Intent(getApplicationContext(), no.class);
startActivity(Appointments);
} else if (selectedFromList.equals("Mango")){
Intent Logout = new Intent(getApplicationContext(), go.class);
startActivity(Logout);
} else if (selectedFromList.equals("Banana")){
Intent Exit = new Intent(getApplicationContext(), low.class);
startActivity(Exit);
}
}

Try this, it will help you.
listView1.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long arg3) {
//global variable
idItem = (int) id;
switch (idItem) {
case 0:
// This is your first Item
// Add your Intent and startActivity
break;
case 1:
// Add your Intent and startActivity
break;
case 2:
// Add your Intent and startActivity
break;
case 3:
// Add your Intent and startActivity
break;
}
}
});
You get over id the item you clicked. Then you can go to the right activity you want for this item.
Hope it helps.

how to pass the value of row in listview to a button

I have created a custom listview using SimpleAdapter and in each row of list view i put a button has single id.
I want to get the position of each row to pass the button but i have a single button id for each row and I want when I click on button it find the position of row and start another activity
please help me
public void click(View v){
//RelativeLayout navi = (RelativeLayout)findViewById(R.layout.custom_row_view);
TextView tv = (TextView)findViewById(R.id.text1);
ImageButton im = (ImageButton)findViewById(R.id.imageButton1);
ListView lv=(ListView)findViewById(android.R.id.list);
int position = 0;
Long id=Long.parseLong((String) adapter.getItem(position));
Intent i=null;
switch(position){
case 1:
i=new Intent(this, ButtonActivity.class);
startActivity(i);
break;
case 2:
i = new Intent(this, PickerActivity.class);
startActivity(i);
break;
}

try this
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1,
final int arg2, long arg3) {
final ProgressDialog progressBar = ProgressDialog.show(
VechiclesDetails.this, "", loadingString);
progressBar.setIndeterminate(true);
progressBar.setIndeterminateDrawable(getResources()
.getDrawable(R.anim.progressbar_handler));
new Thread(new Runnable() {
public void run() {
try {
Intent carDetail = new Intent(
Details.this,
Screen.class);
carDetail.putExtra("index", arg2);
carDetail.putExtra("sellerId", SellerId);
startActivity(carDetail);
progressBar.dismiss();
} catch (Exception e) {
progressBar.dismiss();
}
}
}).start();
}
});

I am not sure about this, but lets try it, and inform me about your success..
The line , int position = listView.getPositionForView(v.getParent());
public void click(View v){
// This line is important
int position = listView.getPositionForView(v.getParent());
//RelativeLayout navi = (RelativeLayout)findViewById(R.layout.custom_row_view);
TextView tv = (TextView)findViewById(R.id.text1);
ImageButton im = (ImageButton)findViewById(R.id.imageButton1);
ListView lv=(ListView)findViewById(android.R.id.list);
int position = 0;
Long id=Long.parseLong((String) adapter.getItem(position));
Intent i=null;
switch(position){
case 1:
i=new Intent(this, ButtonActivity.class);
startActivity(i);
break;
case 2:
i = new Intent(this, PickerActivity.class);
startActivity(i);
break;
}
}
If this not works then only option you have to is making a Custom Adapter and write your button's onClick() in adapter's getView() in which you have a position variable accessible.

On list view, you can use setOnItemClickListener
list.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView parentView, View childView, int position, long id) {
//Put Your code here
}
public void onNothingSelected(AdapterView parentView) {
}
});

Adding multiple event to listview

I searched stackoverflow but couldnt find a answer(sure there is one somewhere) but I am trying to add a activity for each listview input. I can manage it with one intent but how do I give each listview input a seperate activity. So to be clear, I want to make every item have a serperate activity.
Currently use this code to initiate a activity but want individual activities for each item.
public class ListviewActivityActivity extends ListActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// storing string resources into Array
String[] adobe_products = getResources().getStringArray(R.array.list_products);
// Binding resources Array to ListAdapter
this.setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, R.id.label, adobe_products));
ListView lv = getListView();
// listening to single list item on click
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// selected item
String product = ((TextView) view).getText().toString();
// Launching new Activity on selecting single List Item
Intent i = new Intent(getApplicationContext(), BMICalculatorActivity.class);
startActivity(i);
}
});
}
Have tried adding this but it failed to work
private static final int ACTIVITY_0 = 0;
private static final int ACTIVITY_1 = 1;
private static final int ACTIVITY_2 = 2;
protected void onListItemClick(ListView l, View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
final Intent intent = new Intent();
// Set up different intents based on the item clicked:
switch (position)
{
case ACTIVITY_0:
intent.setClass(this, listview.activty.BMICalculatorActivity.class);
break;
case ACTIVITY_1:
intent.setClass(this, listview.activty.BodyLog.class);
break;
I know its probally simple to sort so any help would be amazing. Thanks

I think you want something like this :
Intent i = null;
switch (position)
{
case ACTIVITY_0:
i = new Intent(getApplicationContext(), BMICalculatorActivity.class);
break;
case ACTIVITY_1:
i = new Intent(getApplicationContext(), BodyLog.class);
break;
}
if(i != null)
{
startActivity(i);
}

Try something like this:
// listening to single list item on click
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent i;
// selected item
String product = (String) lv.getItem(position);
if(product.equals("photoshop"))
i = new Intent(ListviewActivity.this, Photoshop.class);
else if (product.equals("final cut pro"))
i = new Intent(ListviewActivity.this, FinalCutPro.class);
else
i = new Intent(ListviewActivity.this, Generic.class);
startActivity(i);
}
});
Another option would be to make a POJO that held the name of the listview entry and the class to call. And add an array of those instead of an array of Strings. This will require using an ArrayAdapter of some kind. Then when you get the Item, you simply call startActivity(new Intent(listviewActivity.this, myPojo.classToCall); You should be able to find a good example of that somewhere on SO...

Listview , open new activity onClick

Hey everyone I've looked for hours trying to find a solution to this, my goal is to have a Listview when it opens well open another activity. Well actually I got it to be able to open another activity when its click but how do I get it so that each list item will open its own activity? I am terribly sorry if this question is already answered but the links I found doesn't really describe what the code is doing [Yes i am a newbie :)]
this is the code im using
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String[] countries = getResources().getStringArray(R.array.countries_array);
setListAdapter(new ArrayAdapter<String>(this, R.layout.newfile, countries));
ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Intent myIntent = new Intent(view.getContext(), Html_file.class);
startActivityForResult(myIntent, 0);
}
});
}
}

lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
if(position == 1) {
//code specific to first list item
Intent myIntent = new Intent(view.getContext(), Html_file1.class);
startActivityForResult(myIntent, 0);
}
if(position == 2) {
//code specific to 2nd list item
Intent myIntent = new Intent(view.getContext(), Html_file2.class);
startActivityForResult(myIntent, 0);
}
}
});

public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
switch( position ) {
case 0: Intent newActivity = new Intent(this, i1.class);
startActivity(newActivity);
break;
case 1: Intent newActivity = new Intent(this, i2.class);
startActivity(newActivity);
break;
case 2: Intent newActivity = new Intent(this, i3.class);
startActivity(newActivity);
break;
case 3: Intent newActivity = new Intent(this, i4.class);
startActivity(newActivity);
break;
case 4: Intent newActivity = new Intent(this, i5.class);
startActivity(newActivity);
break;
}
}

If you have some limited number of list you can use switch case here on position
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Intent myIntent = new Intent(view.getContext(), Html_file.class);
startActivityForResult(myIntent, 0);
}
});

If you know which activity is to be opened when different list items are clicked, then just assign id or tag to the list items.
In the callback of onItemClick, you have a parameter View,
use it to get id or tag to differentiate them and call respective Activity.

// Add ArrayList and ArrayAdapter:
final ArrayList<String> listItems = new ArrayList<String>();
listItems.add("image_one");
listItems.add("image_two");
listItems.add("image_three");
ArrayAdapter<String> myArrayAdapter = new ArrayAdapter<>(this,
android.R.layout.simple_list_item_1, listItems);
myListView.setAdapter(myArrayAdapter);
// Add ArrayList of Classes:
final ArrayList<Class> intents = new ArrayList<Class>();
intents.add(image_one.class);
intents.add(image_two.class);
intents.add(image_three.class);
// Click on list item to open Class from ArrayList of Classes:
myListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int
position, long id) {
Intent listIntent = new Intent(getApplicationContext(),
intents.get(position));
startActivity(listIntent);
}
});
