How to Get Data from Each Dynamically Created Edittext in Android

How to get data from each dynamically created EditText in Android?

In every iteration you are rewriting the ed variable, so when loop is finished ed only points to the last EditText instance you created.

You should store all references to all EditTexts:

EditText ed;
List<EditText> allEds = new ArrayList<EditText>();

for (int i = 0; i < count; i++) {   

    ed = new EditText(Activity2.this);
    allEds.add(ed);
    ed.setBackgroundResource(R.color.blackOpacity);
    ed.setId(id);   
    ed.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
            LayoutParams.WRAP_CONTENT));
    linear.addView(ed);
}

Now allEds list hold references to all EditTexts, so you can iterate it and get all the data.

Update:

As per request:

String[] strings = new String[](allEds.size());

for(int i=0; i < allEds.size(); i++){
    string[i] = allEds.get(i).getText().toString();
}

How to get data from dynamically created EditText using LayoutInflater in android?

     public void goButtonClicked(View view) {
         int numberofPlayersTolayout =       Integer.parseInt(numberOfPlayers.getSelectedItem().toString());
        LayoutInflater inflater = (LayoutInflater)  getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        LayoutParams params = new LayoutParams(LayoutParams.FILL_PARENT,  LayoutParams.WRAP_CONTENT);
        maalContainer.removeAllViews();

        maalText = new EditText[numberofPlayersTolayout];
        points = new EditText[numberofPlayersTolayout];
        result = new TextView[numberofPlayersTolayout];
        for (int i = 0; i < numberofPlayersTolayout; i++) {
            View dynamicEntryView = inflater.inflate(R.layout.player_entry_item, null);
            maalContainer.addView(dynamicEntryView, params);
            TextView playerName = (TextView) dynamicEntryView.findViewById(R.id.player_name_textview);
            playerName.setText("Player :" + (i + 1));

            maalText[i] = (EditText) dynamicEntryView.findViewById(R.id.player_item_edittext_maal);
            points[i] = (EditText) dynamicEntryView.findViewById(R.id.player_item_edittext_point);
            result[i] = (TextView) dynamicEntryView.findViewById(R.id.player_item_textview_result);
}

How to get text from all EditText Dynamically added in a row

You could retrieve the value by looping the parentView, something like this


ArrayList getEditTextList()
{

    ArrayList<String> list = new ArrayList<String>();
    int size = parentLinearLayout.getChildCount()

    for (int i=0 ; i < size ; i++)
    {
      View view = parentLinearLayout.getChildAt(i);
      EditText text = view.findViewById(R.id.yourEditTextName);
      list.add(text.getText().toString());
    }
return list;
}

Later you can add the values to Shared preference either by converting Arraylist to Json String or Adding it one by one.

How to get value from dynamically created edit text in Android?

Although, I didn't get what exactly your question is, still I'll try to help.
What exactly this code does is, on clicking the button on top an new layout(one that you wanted) will add to the activity screen at runtime, i.e an edittext with a button, and when you click on that button, A toast with the value of respective edittext will be shown. Hence solving the problem of getting the value of dynamically added edittext

MainActivity

public class MainActivity extends AppCompatActivity {
    Button generateET;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final LinearLayout myLinearLay = (LinearLayout) findViewById(R.id.dynamic);
        generateET = (Button) findViewById(R.id.generateBtn);
        generateET.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                LayoutInflater l = getLayoutInflater();
                final View viewToAdd = l.inflate(R.layout.to_add, null);
                Button buttonWayPoints = (Button) viewToAdd.findViewById(R.id.btn_waypoint);
                final EditText editTextWayPoints = (EditText) viewToAdd.findViewById(R.id.et_waypoint);

                buttonWayPoints.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        if (editTextWayPoints.getText().toString() != null) {
                            Toast.makeText(MainActivity.this, editTextWayPoints.getText().toString(), Toast.LENGTH_SHORT).show();
                        } else {
                            Toast.makeText(MainActivity.this, "No text found", Toast.LENGTH_SHORT).show();
                        }
                    }
                });
                myLinearLay.addView(viewToAdd);

            }
        });

    }
}

Fetch data from dynamically created TextInputEditText and insert them to an array

I was able to resolve it in following way, thanks for the questioning hellboy and blackapps, it made me think bit differently.

private void fetchCertificates(){

ArrayList<String> certs = new ArrayList<>();

for(int i =0;i<linearLayout.getChildCount();i++){

    View certificateView = linearLayout.getChildAt(i);

    TextInputEditText newCerts = certificateView.findViewById(R.id.new_certs);
    String name = newCerts.getText().toString();
    certs.add(name);
}

String certList = android.text.TextUtils.join(",", certs);
Log.i("Certificates",certs);

}

Get data from each dynamically created EditText

While creating every new EditText, you generate ids by setId() but I don't see how these are going to be useful in your code.

Instead set the tag of the EditText like this:

ed.setTag(allEds.size());

and add it to the list:

allEds.add(ed);

Now in each EditText's tag you have stored its ordinal number (zero based) in the list and when you want to store its value in SharedPreferences you can do:

SharedPreferences.Editor editor = getPreferences(Context.MODE_PRIVATE).edit();
editor.putString("key" + et.getTag().toString(), ed.getText().toString());
editor.commit(); 

or by using a loop through all the items in the list:

for (EditText ed : allEds) {
    editor.putString("key" + et.getTag().toString(), ed.getText().toString());
}
editor.commit();

This way you stored all the text values of the EditTexts with keys like:

"key0", "key1", "key2",... 

Edit

Of you want to open another activity and pass the list to it:

    Intent intent = new Intent(this, AnotherActivity.class);
    ArrayList<String> allTexts = new ArrayList<>();
    for (EditText e : allEds) {
        allTexts.add(e.getText().toString())
    }
    intent.putExtra("Text", (Serializable) allTexts);

and in the other activity's onCreate():

ArrayList<String> list = (ArrayList<String>) getIntent().getSerializableExtra("Texts");

Edit2

Replace the code in btnSave.setOnClickListener() and the lines below, with this code:

btnSave.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View arg0) {
        SharedPreferences.Editor editor = getPreferences(Context.MODE_PRIVATE).edit();
        for (EditText ed : allEds) {
            editor.putString("key" + ed.getTag().toString(), ed.getText().toString());
        }
        editor.commit();

        Intent intent = new Intent(this, MainActivity.class);
        ArrayList<String> allTexts = new ArrayList<>();
        for (EditText e : allEds) {
            allTexts.add(e.getText().toString());
        }
        intent.putExtra("Text", (Serializable) allTexts);
        startActivity(intent);
    }
});  

Get text from dynamically created EditText on click of a button

You are passing to the getOnClickDoSomething function the text of the newly created editText, so understandably it will be blank. What you may want is to change getOnClickDoSomething, so that it accepts reference to the editTexts themselves, and later you can retrieve the their current text. (You will have to be careful not to leak views, as you have anonymous classes holding on to the Views.)

Example: Just change the following lines as follows

bt_plus.setOnClickListener(getOnClickDoSomething(et_one, et_two)); }

View.OnClickListener getOnClickDoSomething(final EditText one1,final EditText two1) 

Log.e("========","=====one ="+one1.getText().toString().trim(),+"=========two = "+two1.getText().toString().trim());
