Transferring Data from EditText from one Activity to EditText of another

Question

When Transferring data from one activity to another, can you transfer from one EditText to another EditText of the other Activity

I'm trying to transfer data from EditText of one Activity to EditText of another Activity.

Answer 1

1 ) Way

First activity

Intent i = new Intent(this, ActivityTwo.class);
AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autocomplete);
String getrec=textView.getText().toString();



//Create the bundle
Bundle bundle = new Bundle();

//Add your data to bundle
bundle.putString(“data”, getrec);

//Add the bundle to the intent
i.putExtras(bundle);

//Fire that second activity
startActivity(i);

Sceond Activity where you get

//Get the bundle
Bundle bundle = getIntent().getExtras();

//Extract the data…
String stuff = bundle.getString(“data”); 

2)Way

public static AutoCompleteTextView textView;

you can access textview with

SceondActivity.textview;

3 Way

Store value in Preference or database

Answer 2

You can send the content of 1st EditText as an intent extra to another activity. In the destination Activity, call getIntent() to extract the intent extras and then you can call setText() on that Activity's EditText

Activity A:

String data=myEditText.getText().toString();
Intent i=new Intent(ActivityA.this,ActivityB.class); //Create Intent to call ActivityB
i.putExtra("editTextKey",data);
startActivity(i);

Activity B:

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.activity_b_layout);
EditText newEditText=findViewById(R.id.new_edittext_id); //Get the reference to your edittext
String receivedData = getIntent().getStringExtra("editTextKey");
newEditText.setText(receivedData); //Set the data to new editteext
...
}

Answer 3

Intents are used for communication between Activities. You should get the text from EditText using EditText.getText().toString() and create an Intent to wrap up the value to be passed eg;

Intent in = new Intent(FirstActivity.this, TargetActivity.class).putExtra("STRING IDENTIFIER","string value from edittext");

You can retrieve this value and set it in EditText Option B use shared preferences like this class I use:

class QueryPreferences 
{
private static final String TEXT_ID = "2";
    static void setPreferences(String text, Context context)
    {
         PreferenceManager.getDefaultSharedPreferences(context)
                          .edit()
                          .putString(TEXT_ID,text)
                          .apply();
    }
    static String getPreferences(Context context)
    {
         return PreferenceManager.getDefaultSharedPreferences(context).getString(TEXT_ID,"");
    }
}

Ref : What's the best way to share data between activities?

You can achive this by

• Send data inside intent
• Static fields
• HashMap of WeakReferences
• Persist objects (sqlite, share preferences, file, etc.)

TL;DR: there are two ways of sharing data: passing data in the intent's extras or saving it somewhere else. If data is primitives, Strings or user-defined objects: send it as part of the intent extras (user-defined objects must implement Parcelable). If passing complex objects save an instance in a singleton somewhere else and access them from the launched activity.

Some examples of how and why to implement each approach:

Send data inside intents

Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
intent.putExtra("some_key", value);
startActivity(intent);

On the second activity:

Bundle bundle = getIntent().getExtras();
int value = bundle.getInt("some_key");
