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

Solution 1:

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();
}

Solution 2:

You can also do like this by taking an Array of EditText. You should store all references to all EditTexts:

EditText ed[] = new EditText[count];    
for (int i = 0; i < count; i++) {   

    ed[i] = new EditText(Activity2.this);

    ed[i].setBackgroundResource(R.color.blackOpacity);
    ed[i].setId(id);   
    ed[i].setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
            LayoutParams.WRAP_CONTENT));
    linear.addView(ed[i]);
}

and you can use for loop to get the value from the EditText .

 for(int i = 0; i < ed.length; i++){

       Log.d("Value ","Val " + ed[i].getText());
  }

Solution 3:

I have a for loop generating dynamic TextViews within TableRows from a JSON string. Here's what I did:

// Generate Dynamic tablerows and set a unique id
//m_jArry is a JSON Array

for(int i = 0; i < m_jArry.length(); i++)
{
    jo_inside = m_jArry.getJSONObject(i);
    TableRow row = new TableRow(getApplicationContext())
    row.setId(jo_inside.getInt("id"));
    ...        
    findViewById(row.getId())
    ...
}

I am using findViewById(row.getId()) to set the dynamic TextView text data to EditText fields in my app. For those of you who do not understand JSON, there are several good tutorials out there (I'm sure there are great explanations here on Stack Overflow) for the Android platform. I'm still an Android newbie, but I hope this is helpful to some of you out there.
