How to get the value of ListView and save it in the EditText or something else in another activitiy

Question

There is any activity with an input field, it calls the second activity with ListView. I need to get the value from the ListView and return it to the input field in the first activity. Can not return a value, but the activity switches without errors.

MainActivity

edTAirportchoice1 = (EditText) findViewById(R.id.edText);
    edText.setOnClickListener(this);

public void onClick(View v) {
        Intent intent = new Intent(MainActivity.this, ListActivity.class);
        startActivityForResult(intent, 1);

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (data == null) {
        return;

    } String name = getIntent().getStringExtra("name");
    edText.setText(name);
    }

}

ListActivity

list1 = (ListView) findViewById(R.id.list1);
    list1.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, s1));
    list1.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Toast.makeText(getApplicationContext(), s1[position], Toast.LENGTH_LONG).show();
            Intent intent = new Intent(ListActivity.this, MainActivity.class));
            intent.putExtra("name", s1[position]);
            setResult(1,intent);        
            finish();

public void onClick(View v) {
    Intent intent = new Intent(ListActivity.this, MainActivity.class);
    intent.putExtra("name", edText.getText().toString()); //("name", list1.getOnItemClickListener().toString())- the same result
    startActivity(intent);

In OnItemClick don't start again the activity, use setResult instead. Also the selectedREsult is a Serializable, and you are expecting a string... — Chol, Jan 19 '16 at 11:53
yes, value is set in edittext and this value is not returned so @AmitVaghela — l2win36, Jan 19 '16 at 12:14
"In OnItemClick don't start again the activity" - right, but Without these lines of code in OnItemClick my listview is not clickable... @Chol — l2win36, Jan 19 '16 at 12:19
Yes but do not put this line: startActivity(intent), use setResult(1, intent) — Chol, Jan 19 '16 at 13:09
For some reason it does not work properly, value of listview is not returned, and it looks like " a backbutton to first activity" @Chol — l2win36, Jan 19 '16 at 14:33
Put a log in the OnActivityResult to see if it is reached, then take a closer look to the extra, you are putting a serializable, but you are trying to retrieve a string — Chol, Jan 19 '16 at 14:44

Intent intent = new Intent(); 
        intent.putExtra("name", selectedResult); 
        setResult(1, intent);

Use Intent for this purpose,

From ListActivity to MainActivity

public void onClick(View v) {
    Intent intent = new Intent(ListActivity.this, MainActivity.class);
    intent.putExtra("name", list1.getOnItemClickListener().toString());
    startActivity(intent);
}

Now in MainActivity to get this value of name ,

String name= getIntent().getStringExtra("name");

Now to set value in your textview of MainActivity ,

txtView.setText(name);

Yes, I guess this is the way! – zIronManBox Jan 19 '16 at 12:14
Can I try it to edittext and return the value there? @AmitVaghela – l2win36 Jan 19 '16 at 12:21
Unfortunately not,this value is not returned so. Should I write " String name= getIntent().getStringExtra("name") " in MainActivity in method "onActivityResult" ? @AmitVaghela – l2win36 Jan 19 '16 at 12:59
@AmitVaghela Maybe the problem is the announcement of the list in MainActivity, actually that's it - private ListView list1 = null; private String s1[] = {"a", "b", "c", "d", "e", "f"} – l2win36 Jan 19 '16 at 13:52
Thanks for your suggestions, but still its not working @AmitVaghela – l2win36 Jan 19 '16 at 15:51
I updated the post, still result in the list is not saved in editext. There is no error in the debugger. Can you take a look? @AmitVaghela – l2win36 Jan 19 '16 at 16:48
what you are getting in 'name' , String name = getIntent().getStringExtra("name"); @I2win36 – Amit Vaghela Jan 19 '16 at 17:20
@AmitVaghela I'm sorry I know why it get an error,now everything looks great, Thanks you – l2win36 Jan 19 '16 at 18:12

The right way of sharing some data between 2 activities is:

public static final int REQUEST_LIST = 1;

// Call this to show ListActivity
Intent intent = new Intent(MainActivity.this, ListActivity.class);
startActivityForResult(intent, REQUEST_LIST);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        switch(requestCode) {
            case REQUEST_LIST:
               if (data == null) return;
               String name = getIntent().getStringExtra("name");
               edText.setText(name);
               break;

            default:
               break;
        }
    }
}

Then in ListActivity you need:

list1 = (ListView) findViewById(R.id.list1);
list1.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, s1));
list1.setOnItemClickListener(new AdapterView.OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Intent resultIntent = new Intent();
        resultIntent.putExtra("name", s1[position]);
        setResult(RESULT_OK, resultIntent);        
        finish();
});

Cool! Good luck in your Android Development carier. – Yev Kanivets Jan 20 '16 at 10:22 — Yev Kanivets, Jan 20 '16 at 10:22
