I have two class first is PageOne and Second is PageTwo, PageOne has list of content and on click on content, that content pass to PageTwo Class.
PageOne Class Using this code to track click contents
public void onItemClick(AdapterView parent, View view, int position, long id) {
String s = (lv.getItemAtPosition(position).toString());
Intent i=new Intent(PageOne.this, PageTwo.class);
i.putExtra("name", s);
startActivity(i);
}
and PageTwo class can catch that content using this code
TextView Textv = (TextView) findViewById(R.id.singleidview);
Intent iin = getIntent();
Bundle b = iin.getExtras();
if (b != null) {
String j = (String) b.get("name");
Textv.setText(j);
}
when this String j output is:
{description=description about selected, title=selected title}
I searching a way for display description on one TextView and title in another TextView. How to do this, I can do this using split function. But I am searching a better way than using split.
Thank you...
Try this way
Intent iin = getIntent();
Bundle b = iin.getExtras();
if (b != null) {
String j = (String) b.get("name");
JSONObject name = new JSONObject(j);
Textv.setText(name.getString("title"));
TextvDesc.setText(name.getString("description"));
}

This is the first activity
Intent intent = new Intent(Songs.this,PlayingSong.class);
Bundle bundle=new Bundle();
bundle.putStringArray("data",songs);
intent.putExtras(bundle);
startActivity(intent);
This is the second activity
tv = (TextView)findViewById(R.id.playingSongName);
imge = (ImageView)findViewById(R.id.playingImage);
Bundle bundle = getIntent().getExtras();
String[] arrRecd = bundle.getStringArray("data");
tv.setText(arrRecd[]);
You can't set a String Array directly to the TextView. Instead create a String and set it to the TextView.
String text = "";
for(int i = 0; i < arrRecd.length; i++) {
text = text + arrRecd[i];
}
tv.setText(text);
In First Activity :
Intent intent=new Intent(this,SearchActivity.class);
intent.putStringArrayListExtra("data",songs);
startActivity(intent);
In second activity:
ArrayList<String> list=getIntent().getStringArrayListExtra("data");
Why the value did not appear in the second activity which is consultDoctorAnaemia? I think the code is already correct. But it display null.
resultAnaemia
if(symptom16.equals("Yes"))
{
weight=0.11;
newWeight = 0.0 * 0.15; //cf disease = 0.6, [min=0.15]
String cf = Double.toString(newWeight);
Intent intent = new Intent(resultAnemia.this, consultDoctorAnaemia.class);
intent.putExtra("cfDiseases", cf);
startActivity(intent);
}
consultDoctorAnaemia
TextView textView = (TextView) findViewById(R.id.textCF);
//get passed intent
Intent intent = getIntent();
if(null != intent)
{
//get cf value from intent
String cf = intent.getStringExtra("cfDiseases");
textView.setText("Certainty value : " + cf);
}
Bundle extras = getIntent().getExtras();
if (extras != null) {
String Diseases = extras.getString("cfDiseases");
}
You need to do in the consultDoctorAnaemia activity:
Bundle bundle = getIntent().getExtras();
String value2 = bundle.getString("cfDiseases");
Try this in first activity:
// do your intent setup somewhere and then setup bundle
Bundle info = new Bundle();
info.putString("cfDiseases", cf);
intent.putExtras(info);
startActivity(intent);
In new activity:
Bundle info = new Bundle();
info = getIntent().getExtras();
cf = info.getString("cfDiseases");
You can also pass value like this way
Declare your string global and static For example
Declare in variable in this class
Class A
public class A extends Activity{
static String cf = "abcde";
}
Access variable in this B class
class B
public class B extends Activity{
String Temp;
//you can get variable like this
Temp=A.cf ;
Toast.makeText(B.this, "Temp = "+Temp, Toast.LENGTH_SHORT).show();
}
I want to send int parameter in intent like this:
String textname = (String) dataItem.get("name");
Intent m = new Intent(list.this,main.class);
m.putExtra("name",textname);
m.putExtra("page",1);
startActivity(m);
and in main class I get that parameter
Intent intent = getIntent();
name = intent.getStringExtra("name");
page1 = Integer.parseInt(intent.getStringExtra("page"));
but when I run my code it force closes!!!
You should use getIntent().getIntExtra(name, defaultValue) instead of Integer.parseInt(intent.getStringExtra("page"));
Update:
int defaultValue = -1;// take any default value of your choice
String name = intent.getStringExtra("name");
int page1 = intent.getIntExtra("page", defaultValue);
I in other class use the main class and send parameter to it and it work without any problem but just in list class i have problem
in other class i like this send parameter
protected void onListItemClick(ListView l, View v, int position, long id) {
Intent i = new Intent(list_sub.this,main.class);
i.putExtra("name", Name[position]);
i.putExtra("page", Ted[position]);
startActivity(i);
}
and in refresh class i get ted parameter
private void refresh(){
db.open();
int s = db.List_count("text", ID);
Name= new String[s];
Ted=new String[s];
for(int i=0;i<s;i++){
Name[i]=db.List_display_sub("text", ID, i);
Ted[i]=db.page_count("text", Name[i].toString())+"";
}
db.close();
}
Activity A
String textname = (String) dataItem.get("name");
Intent m = new Intent(list.this,main.class);
m.putExtra("name",textname);
m.putExtra("page",1);
startActivity(m);
Activity B
Intent intent = getIntent();
name = intent.getStringExtra("name");
int page = intent.getIntExtra("page", 0);
where 0 is the default value.
I am trying to modify an Android app to suit my need.
The original app has page 1 to display list of notes, and page 2 displays the detailed note.
What I'm trying to achieve is instead of having only 1 textbox in the detailed note page, I want it to have several textboxes, and persist it as well.
Here is how I thought it would be (but failed miserably of course).
This the transmitter on the page 2 (detailed page) activity:
private void saveAndFinish()
{
EditText et = (EditText) findViewById(R.id.eventTitle);
String eventTitle = et.getText().toString();
EditText et2 = (EditText) findViewById(R.id.eventDate);
String eventDate = et2.getText().toString();
EditText et3 = (EditText) findViewById(R.id.eventVenue);
String eventVenue = et3.getText().toString();
EditText et4 = (EditText) findViewById(R.id.eventLocation);
String eventLocation = et4.getText().toString();
EditText et5 = (EditText) findViewById(R.id.eventNote);
String eventNote = et5.getText().toString();
EditText et6 = (EditText) findViewById(R.id.eventAttendees);
String eventAttendees = et6.getText().toString();
Intent intent = new Intent();
// pass these to the main activity will ya?
intent.putExtra("key", data.getKey());
intent.putExtra("title", eventTitle); // eventTitle is the edited text!
intent.putExtra("date", eventDate);
intent.putExtra("venue", eventVenue);
intent.putExtra("location", eventLocation);
intent.putExtra("note", eventNote);
intent.putExtra("attendees", eventAttendees);
setResult(RESULT_OK, intent);
// work done, go back to calling activity
finish();
}
This the receiver on the page 1 (main page) activity:
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode==DETAIL_ACTIVITY_REQ && resultCode==RESULT_OK)
{
DataItem event = new DataItem();
event.setKey(data.getStringExtra("key"));
event.setTitle(data.getStringExtra("title"));
event.setDate(data.getStringExtra("date"));
event.setVenue(data.getStringExtra("venue"));
event.setLocation(data.getStringExtra("location"));
event.setNote(data.getStringExtra("note"));
event.setAttendees(data.getStringExtra("attendees"));
datasource.update(event);
refreshDisplay();
}
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id)
{
// which list view item was selected?
DataItem data = eventsList.get(position);
//now, to navigate. which class should i go to next?
Intent intent = new Intent(this, DetailedActivity.class);
// and also, pass data to the next activity will ya?
intent.putExtra("key", data.getKey());
intent.putExtra("title", data.getTitle());
intent.putExtra("date", data.getDate());
intent.putExtra("venue", data.getVenue());
intent.putExtra("location", data.getLocation());
intent.putExtra("note", data.getNote());
intent.putExtra("attendees", data.getAttendees());
// go go go!
startActivityForResult(intent, DETAIL_ACTIVITY_REQ);
}
Apparently only the "title" is saved, everything else is not. Help?
modify your code in saveAndFinish method
Intent intent = new Intent(thisActivityname.this,secondActivityname.class);
startActivity(intent);
Above code is put data and send to second activity.
now get above data in second activity
Intent intent = getIntent();
String title = intent.getStringExtra("title");
String date = intent.getStringExtra("date");
String venue = intent.getStringExtra("venue");
String location = intent.getStringExtra("location");
String note = intent.getStringExtra("note");
String attendees = intent.getStringExtra("attendees");
You must use getIntent() to get the data from Intent:
data = getIntent();
use on ActivityResult:
data = getIntent();
I have a way that I know is not the best way of sending them over rite now but I'm sending them as strings and converting them to an Int on the reciver side, the problem is when I do the conversion it crashes on my phone. This is what I have on my sender side:
public void sendMessage(View view) {
// Do something in response to button
Intent intent = new Intent(this, PayTracker.class);
// hourly wage send
EditText editText = (EditText) findViewById(R.id.hourly_wage);
String message1 = editText.getText().toString();
intent.putExtra(MESSAGE_1, message1);
// ot wage send
EditText editText1 = (EditText) findViewById(R.id.ot_wage);
String message2 = editText1.getText().toString();
intent.putExtra(MESSAGE_2, message2);
// hours per day send
EditText editText2 = (EditText) findViewById(R.id.hours_day);
String message3 = editText2.getText().toString();
intent.putExtra(MESSAGE_3, message3);
// start new activity
startActivity(intent);
And this is what is on my reciving side:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pay_tracker);
getActionBar().setDisplayHomeAsUpEnabled(true);
// Receive messages from options page
Intent intent = getIntent();
String message1 = intent.getStringExtra(Options.MESSAGE_1);
String message2 = intent.getStringExtra(Options.MESSAGE_2);
String message3 = intent.getStringExtra(Options.MESSAGE_3);
// convert string to integer
int HW = Integer.valueOf(message1);
int OTW = Integer.valueOf(message2);
int HPD = Integer.valueOf(message3);
Ive tested everything and its the conversion that is causing the app to crash, i was hoping somebody could help me make it not crash or give me a whole new way sending an int to my second activity insted of sending a string and converting it.
Thank you!
=======================================================================
Here is my new code with all your help!
Sending:
public void sendMessage(View view) {
// Do something in response to button
Intent intent = new Intent(this, PayTracker.class);
// Gather text from text boxes
EditText editText = (EditText) findViewById(R.id.hourly_wage);
EditText editText1 = (EditText) findViewById(R.id.ot_wage);
EditText editText2 = (EditText) findViewById(R.id.hours_day);
//Create String from text
String message1 = editText.getText().toString();
String message2 = editText1.getText().toString();
String message3 = editText2.getText().toString();
//Convert String to Int
int HW = 0, OTW = 0, HPD = 0;
try{
HW = Integer.valueOf(message1);
OTW = Integer.valueOf(message2);
HPD = Integer.valueOf(message3);
}
catch(NumberFormatException nfe){
//do something else here
//for e.g. initializing default values to your int variables
}
// Send Integers to PayTracker.java
intent.putExtra(MESSAGE_HW, HW);
intent.putExtra(MESSAGE_OTW, OTW);
intent.putExtra(MESSAGE_HPD, HPD);
// start new activity
startActivity(intent);
}
Receiving side:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pay_tracker);
getActionBar().setDisplayHomeAsUpEnabled(true);
// Receive messages from options page
Intent intent = getIntent();
int HW = intent.getIntExtra(Options.MESSAGE_HW, 0);
int OTW = intent.getIntExtra(Options.MESSAGE_OTW, 0);
int HPD = intent.getIntExtra(Options.MESSAGE_HPD, 0);
// set textview
TextView textView = (TextView) this.findViewById(R.id.yourpay);
textView.setText(String.valueOf(HW));
}
You don't need to pass Integers as Strings to be converted back in the receiving Activity. Intents can hold Integers as well as Strings.
Simply add your data like you normally would:
int foo = 5;
Intent intent = new Intent(this, bar.class);
intent.putExtra("foobar", foo);
And then retrieve your int from the intent in the receiving Activity as follows.
Intent intent = getIntent();
int foo = intent.getIntExtra("foobar", 0);
Intents can hold more data than just Strings. In fact, take a look at the documentation. You can see that Intents can hold Longs, Doubles, Floats, Parcelables, etc.
Pass data from one activity to another activity "String" value.useing intent
Activityone
Intent intent = new Intent(Activityone.this,Activitytwo.class)
intent.putExtra("TYPE", type);
startActivity(intent);
Activitytwo
Intent intent =getIntent();
Receivevalue =intent.getExtras().getString("TYPE");
(OR)
Receivevalue = getIntent().getExtras().getString("TYPE");
Pass data from one activity to another activity "Integer" value.useing intent
Activityone
Intent intent = new Intent(Activityone.this,Activitytwo.class)
intent.putExtra("TYPE", type);
startActivity(intent);
Activitytwo
Intent intent = getIntent();
value = intent.getIntExtra("TYPE", 0);
// Type = intent.getIntExtra(name, defaultValue);
Try something like this on the send side:
String message1 = editText.getText().toString();
intent.putExtra("MESSAGE_1", message1);
String message2 = editText1.getText().toString();
intent.putExtra("MESSAGE_2", message2);
String message3 = editText2.getText().toString();
intent.putExtra("MESSAGE_3", message3);
Receive side:
if (getIntent() != null) {
if (getIntent().getExtras() != null) {
String mess1 = getIntent().getExtras().getString("MESSAGE_1");
String mess2 = getIntent().getExtras().getString("MESSAGE_2");
String mess3 = getIntent().getExtras().getString("MESSAGE_3");
}
}
You can achieve your goal using following code
In Your Calling Activity
Intent value = new Intent(YourCallingActivity.this,DestinationActivity.class);
value.putExtra("integerone", integeronevalue);
value.putExtra("integertwo", integertwovalue);
value.putExtra("integerthree", integertwovalue);
startActivity(value);
In Destination Activity
int integerone = getIntent().getExtras().getInt("integerone");
int integertwo = getIntent().getExtras().getInt("integertwo");
int integerthree = getIntent().getExtras().getInt("integerthree");
Hope it helps
Encapsulate the conversion part within try/catch block, because your strings may not be convertible into integer values.
int HW, OTW, HPD;
try{
HW = Integer.valueOf(message1);
OTW = Integer.valueOf(message2);
HPD = Integer.valueOf(message3);
}
catch(NumberFormatException nfe){
//do something else here
//for e.g. initializing default values to your int variables
}
*Or more appropriately, pass the integer values in your sending part and receive them as it is.
