I try to pass a string from one activity to another activity.
This is the coding in Activity A:
#Override
public void onSaveInstanceState(Bundle savedInstanceState) {
savedInstanceState.putString("UserName", UserName);
Log.i(Tag, "UserName1: "+ UserName);
super.onSaveInstanceState(savedInstanceState);
}
In Activity B I use this code to get the string:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.add_item);
setUpViews();
if (savedInstanceState != null){
UserName = savedInstanceState.getString("UserName");
}
Log.i(Tag, "UserName2: "+ UserName);
}
But the logcat shown the first log "UserName1" when I clikc the open to Activity B,
and show the second log "UserName2" as "null".
May I know what wrong with my code?
What I want to do is Activity A pass the String in Activity B when I click the "button" and intent to Activity B. So I can get the String value in Activity B.
Any Idea? Cause I getting error when using intent.putStringExtra() and getintent.getStringExtra(), so I change to use onSaveInstanceState (), but still having problem.
EDIT:
This is my original code, I can get the String in Activity B, but unexpected I can't save my data in Sqlite. If remove the putString Extra then everything go smoothly.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
Intent addItem = new Intent(ItemActivity.this, AddEditItem.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
addItem.putStringExtra("UserName", UserName);
Log.e(Tag, "UseName: "+ UserName);
startActivity(addItem);
return super.onOptionsItemSelected(item);
}
Code in Activity B:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.add_item);
setUpViews();
UserName = (String) getIntent().getStringExtra("UserName");
Log.e(Tag, "UserName3: "+ UserName);
}

onSaveInstanceState is not used in that purpose, its used to save your activity state on for example orientation change, or when you leave an activity and get back to it.
What you need is to use intents.
Other than starting activity, intents can also carry some information throughout app, like this:
This would be activity 1:
Intent = new Intent (getApplicationContext(), Activity2.class);
intent.putExtra("UserName", UserName);
startActivity(intent);
and to recover it in second activity use:
String username = getIntent().getExtras().getString("UserName");
May I know what wrong with my code?
onSaveInstanceState() has nothing to do with passing data between activities. Instead, you need to put your string in an extra on the Intent used with startActivity().
Cause I getting error when using intent.putExtra() and getintent.getExtra()
Since that is the correct approach (albeit using getStringExtra()), please go back to it and fix whatever error you are encountering.

Here, I want to make an app which is having profile activity and user can see his/her information in that and the activity has one button for editing the profile. When button is clicked the new activity is opened where user can edit there information & press save button and then return to profile activity.

Before OP posted code
You can define a function that loads your data for ProfileActivity and call it in onResume().
#Override
public void onResume() {
super.onResume();
if (this.reloadNedeed)
this.reloadProfileData();
this.reloadNeeded = false; // do not reload anymore, unless I tell you so...
}
This way, since onResume() is also called after onCreate(),
you'd be using the same code both for when the the activity is first created and for when you re-open it (e.g. when you come back from another activity, or another app).
In order to make it work, reloadNedeed must be set to true by default:
private boolean reloadNeed = true;
In order to start the EditActivity you can do:
startActivityForResult(new Intent(EditActivity.class), EDIT_CODE);
where EDIT_CODE can be any number, e.g:
private static final int EDIT_CODE = 31;
When you want to get back to from EditActivity you just call:
Intent returnIntent = new Intent();
setResult(Activity.RESULT_OK,returnIntent); // or RESULT_CANCELED if user did not make any changes
// it would be better to use some custom defined codes here
finish();
This would trigger the function onActivityResult(int, int Intent) in ProfileActivity, in which you can tell the activity to reload the data.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == EDIT_CODE) { // Ah! We are back from EditActivity, did we make any changes?
if (resultCode == Activity.RESULT_OK) {
// Yes we did! Let's allow onResume() to reload the data
this.reloadNeeded = true;
}
}
onResume() is called after onActivityResult(), so we can safely decide whether to put reloadNeeded to true, or just leave it to false.
Edit: After OP posted code
I haven't tested your code, but I may have found some oddities just by looking at it.
I believe you may have a problem with some if-else conditions in your load_user_info() function.
When you get back from EditActivity the activity is (most likely) not created again. Only onResume() is called, which calls load_user_info();
But since the Activity isn't recreated, your variables hold the same values from when they were initialized in onCreate().
When he does check the data:
if(name != null && name !=""){
tv_name.setText(name);
}else if(db_name != null && db_name !=""){
tv_name.setText(db_name);
}
your activity says:
Heyy, name is not null and is different than "" (by the way you should use equals(), even for literals)
Therefore, I will execute this piece of code tv_name.setText(name);, and since it's an if else statement, the second block will NOT be executed.
So your activity, never really displays the updated data. The same data as before is displayed.
You should try to apply the same logic as I posted in my original answer.
Hope I understood your question right...
There are multiple ways to accomplish what you are asking. There's the simple(ish) way and the hard(er) and more correct way.
The easiest way is to refresh the data you're expecting in the onResume of the activity you are returning to. If you navigate to a different activity, the previous activity will call onPause, then onResume when you return, and at that time you can check for new data and load it in place. That's the quicker way.
A better, more correct way of doing it would be to implement a ViewModel and use LiveData to allow the Activity to always have the most up to date data. This does require a bit of extra effort on your end to make sure your app has proper architecture, but in the long run pays off way better. Check out Android's architecture components.
To refresh your activity data:
finish();
startActivity(getIntent());
onBackPressed or finish() then its call and refresh
#Override
public void onRestart()
{
super.onRestart();
finish();
startActivity(getIntent());
}
I hope this helpful...
I am trying to figure out where I went wrong either coding or logical flaw, I created a Recipe App that takes a couple of strings and an image, all data get saved into database and on the main screen I get a list of recipes from database.
Main Screen
Add / Edit Screen
Creating or Adding new Data is working as expected, all data get saved. The problem is everything can be updated except for the Image once it has been saved any second attempt doesn't seem to affect the image, the image remains the same.
The core principle is to set data to the views (When user start the activity onCreate or resume the activity onResume) and get data from the views (When user leaves onPause and onSaveInstanceState just incase an update was made)
Code
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add_edit);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
enableEdit();
fab.hide();
}
});
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
recipeDAOImp = new RecipeDAOImp(this);
recipeDAOImp.open();
findViews();
rowId = (savedInstanceState == null) ? null :
(Long) savedInstanceState.getSerializable(RecipeDAOImp.KEY_ID);
if (rowId == null) {
Bundle extras = getIntent().getExtras();
rowId = extras != null ? extras.getLong(RecipeDAOImp.KEY_ID)
: null;
}
populateData();
disableEdit();
}
private void findViews() {
// Finds Views and Set onClick to imageButton
}
private void disableEdit() {
// Disable Views
}
private void enableEdit() {
// Enables Views
}
private void populateData() {
// If rowId is available then user is trying to Edit Recipe
if (rowId != null) {
setTitle("Edit Recipe");
Recipe recipe = new Recipe(rowId);
Cursor cursor = recipeDAOImp.getRecipe(recipe);
startManagingCursor(cursor);
title.setText(cursor.getString(
cursor.getColumnIndexOrThrow(RecipeDAOImp.KEY_TITLE)));
ingredients.setText(cursor.getString(
cursor.getColumnIndexOrThrow(RecipeDAOImp.KEY_INGREDIENTS)));
steps.setText(cursor.getString(
cursor.getColumnIndexOrThrow(RecipeDAOImp.KEY_STEPS)));
category.setText(cursor.getString(
cursor.getColumnIndexOrThrow(RecipeDAOImp.KEY_CATEGORY)));
BitmapDrawable bitmapDrawable = new BitmapDrawable(getResources(), DbBitmapUtility.getImage(cursor.getBlob(
cursor.getColumnIndexOrThrow(RecipeDAOImp.KEY_IMAGE))));
image.setBackground(bitmapDrawable);
// Else user is Adding a new Recipe
} else {
fab.hide();
setTitle("Add Recipe");
enableEdit();
}
}
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
saveState();
outState.putSerializable(RecipeDAOImp.KEY_ID, rowId);
}
#Override
protected void onPause() {
super.onPause();
saveState();
}
#Override
protected void onResume() {
super.onResume();
populateData();
}
private void saveState() {
// Get the values from the views
String titleString = title.getText().toString();
String ingredientString = ingredients.getText().toString();
String stepsString = steps.getText().toString();
String categoryString = category.getText().toString();
// Get the image from imageButton
Drawable drawable = image.getBackground();
Bitmap bitmap = ((BitmapDrawable) drawable).getBitmap();
byte[] imageData = DbBitmapUtility.getBytes(bitmap);
// Just to clarify image is never null as the backround is a camre image
if (titleString.equals(null) || "".equals(titleString) || ingredientString.equals(null) || "".equals(ingredientString) || stepsString.equals(null) || "".equals(stepsString) || categoryString.equals(null) || "".equals(categoryString) || imageData.equals(null) || "".equals(imageData)) {
Toast.makeText(this, "No Data Saved", Toast.LENGTH_SHORT).show();
} else {
Recipe recipe = new Recipe(titleString, ingredientString, stepsString, categoryString, imageData);
// If rowId is not Available then user is Creating a new Recipe
if (rowId == null) {
long id = recipeDAOImp.createRecipe(recipe);
if (id > 0) {
rowId = id;
}
} else {
recipe.setId(rowId);
recipeDAOImp.updateRecipe(recipe);
}
}
}
#Override
public void onClick(View view) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
// Set the imageButton
BitmapDrawable bitmapDrawable = new BitmapDrawable(getResources(), imageBitmap);
image.setBackground(bitmapDrawable);
}
}
}
DAO
#Override
public boolean updateRecipe(Recipe recipe) {
ContentValues contentValues = new ContentValues();
contentValues.put(KEY_TITLE, recipe.getTitle());
contentValues.put(KEY_INGREDIENTS, recipe.getIngredients());
contentValues.put(KEY_STEPS, recipe.getSteps());
contentValues.put(KEY_CATEGORY, recipe.getCategory());
contentValues.put(KEY_IMAGE, recipe.getImage());
return sqLiteDatabase.update(DATABASE_TABLE, contentValues, KEY_ID + "=" + recipe.getId(), null) > 0;
}
What could be the problem that I can update string data but I can't really update the image once its saved?
After much research and testing, the problem was simply the image button can not be reset.
image.setBackground(bitmapDrawable);
This method above seems not to work for an update, my quick fix was simply to leave the code as it is and simply add a detection onActivityResult to determine if its actually an update then, add the byte data to database directly, rather than updating the image button and then recreate() the Activity, expensive procedure but not costly for a simple app.
if (rowId != null) {
...
recipe.setImage(DbBitmapUtility.getBytes(imageBitmap));
recipeDAOImp.updateRecipe(recipe);
recreate();
}
All Working as expected.
My guess is that the problem is in your DAO code. I have a similar setup (sqlite table with text and blob columns, both get updated), so I know that what you're trying to do is possible.
This is a strange problem that only started yesterday, and I can't think of anything in my code that would have changed anything. I'm setting up a User on Parse, which includes profile information. Now, for some reason (and I can't find ANYTHING about this particular issue online) when I submit the user profile information, while all of the related fields in the app are correctly retrieving the data from Parse (which means it's out there)... when I look at the User on Parse.com all of the fields are marked as (undefined). This is most likely a JSON error, but I can't figure out where it is coming from? Here's my code for the user to submit their profile... see anything? I will add... The user has already signed up in another activity preceding this one.
public class CreateProfileActivity extends AppCompatActivity {
private ParseUser mCurrentUser;
private ParseFile mUserProfilePic;

mProgressBar.setVisibility(View.INVISIBLE);
//INITIALIZE PARSE USER
mCurrentUser = ParseUser.getCurrentUser();

}
Ok. So I haven't figured out why, so if anyone knows why please tell me why. When I switched the value being stored in mCurrentUser.put("totalRevenue", "0.00"); to mCurrentUser.put("totalRevenue", 0.00); which stores as a Number on Parse.com. I'm not sure why storing the value as a String was nullifying everything else that was being stored but it was. After the change, all the data appears and is saved to Parse.com.
Check exactly what's the error .... ur getting
public void done(ParseException e) {
if (e != null) {
goToHomeScreen();
}
else {
Log.d("Error", "Error: " + e.getMessage());
Toast.makeText(getApplicationContext(), " Error: "+e.getMessage() , Toast.LENGTH_SHORT).show();
}
}
Good day!
i am quite new in programming and i am trying to make a simple android app. i have here 2 edittext and 2 buttons inside my activity and what i want them to do is get the number of prefered contacts to text and the 1st edittext and 1st button succeeded but my problem is the button 2 also put the number on the 1st edittext that is supposed to put in 2nd edittext any idea?
this is my code..
public class SA extends Activity {
EditText con1;
EditText con2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_s);
con1 = (EditText) findViewById(R.id.cnum1);
con2 = (EditText) findViewById(R.id.cnum2);
((Button)findViewById(R.id.btnSelectContact1)).setOnClickListener( new OnClickListener() {
#Override
public void onClick(View v) {
// user BoD suggests using Intent.ACTION_PICK instead of .ACTION_GET_CONTENT to avoid the chooser
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
// BoD con't: CONTENT_TYPE instead of CONTENT_ITEM_TYPE
intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE);
startActivityForResult(intent, 1);
}
});
((Button)findViewById(R.id.btnSelectContact2)).setOnClickListener( new OnClickListener() {
#Override
public void onClick(View v2) {
// user BoD suggests using Intent.ACTION_PICK instead of .ACTION_GET_CONTENT to avoid the chooser
Intent intent2 = new Intent(Intent.ACTION_GET_CONTENT);
// BoD con't: CONTENT_TYPE instead of CONTENT_ITEM_TYPE
intent2.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE);
startActivityForResult(intent2, 1);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (data != null) {
Uri uri = data.getData();
if (uri != null) {
Cursor c = null;
try {
c = getContentResolver().query(uri, new String[]{
ContactsContract.CommonDataKinds.Phone.NUMBER,},
null, null, null);
if (c != null && c.moveToFirst()) {
String number = c.getString(0);
showSelectedNumber(number);
}
} finally {
if (c != null) {
c.close();
}
}
}
}
}
protected void onActivityResult2(int requestCode2, int resultCode2, Intent data2) {
if (data2 != null) {
Uri uri2 = data2.getData();
if (uri2 != null) {
Cursor c2 = null;
try {
c2 = getContentResolver().query(uri2, new String[]{
ContactsContract.CommonDataKinds.Phone.NUMBER,},
null, null, null);
if (c2 != null && c2.moveToNext()) {
String number2 = c2.getString(0);
showSelectedNumber(number2);
}
} finally {
if (c2 != null) {
c2.close();
}
}
}
}
}
public void showSelectedNumber(String number) {
con1.setText(number);
}
public void showSelectedNumber2(String number2) {
con2.setText(number2);
}
No need of onActivityResult2() because startActivityForResult() gives you result back in onActivityResult() method.
So now your question would be, how you can manage different requests? Well, that you can do by passing different request code while calling startActivityForResult().
For example:
startActivityForResult(intent, 1); // first request
startActivityForResult(intent, 2); // second request
// you can pass any random number as a request code
Now you just need to perform the operations according to the request code received back in onActivityResult() method.
For example:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (data != null) {
if(requestCode == 1) {
...
...
} else if (requestCode == 2) {
...
...
}
}
}
I had idea to build simple app that can store text and images. I started from Notepad Tutorial (http://developer.android.com/training/notepad/index.html) from first and second exercise.
After I did second I arrange exercise to handle images, it was working very well unless user tapped back button in device. With help came thid exercise where the goal to handling life-cycle events. I managed to did it, it is working very well for old entries in database, but when I try to add new Image, my ImageView is not filled with just taken photo.
Can you spot where is the problem?

The Intent android.provider.MediaStore.ACTION_IMAGE_CAPTURE does not return a byte array in its 'data' Extra. It returns a Uri to the image, which must be opened e.g.
Uri uri = data.getData();
This provides the content path to the image, which can be loaded using a ContentResolver:
InputStream input = context.getContentResolver().openInputStream(uri);
Bitmap bitmap = BitmapFactory.decodeStream(input);
You will need to ensure you check that the Uri exists and handle errors gracefully, you should never assume that another app is going to do something sensible, and should expect malformed/missing data wherever possible.
