try on text changed listener as described in the link to update the variable whenever user changes the edit text, then variable will hold the changed value and so you can use your method to change values of that variable

<ul>
<li>Design a layout as you want with two buttons and one edittext in middle</li>
<li>Then give one button addition funtionality and other substraction functionality</li>
</ul>

Follow little code snippet, provided below

<pre><code>addButton.setOnClickListener(new OnClickListener(){
public void onClick(){
 int valueInEditText = Integer.parseInt(etReference.getText().toString());
 etReference.setText(String.valueOf(valueInEditText + 1));
}
});
</code></pre>

Similaryly, do it for substration button.

You might want to use the <code>NumberPicker</code> which will allow you to select any value.

It's not the same look but it might work for you:

After reading through various posts, examples, articles and Android documentation I found solution to my own question, It can be achieved by two ways:

<blockquote>
 <ol>
 <li>First by using <code>NumberPicker</code></li>
 <li>Secondly by adding <code>TextChangedListener</code> to the <code>EditText</code></li>
 </ol>
</blockquote>

Here is the code how I achieved it :

<pre><code>int noOfCups = 2;
EditText editTextNoOfCups;

editTextNoOfCups = (EditText) findViewById(R.id.edit_text_no_of_cups);
 editTextNoOfCups.addTextChangedListener(new TextWatcher() {
 @Override
 public void beforeTextChanged(CharSequence s, int start, int count, int after) {

 }

 @Override
 public void onTextChanged(CharSequence s, int start, int before, int count) {

 if(s.length() != 0) {
 Log.e("pss", String.valueOf(s));
 noOfCups = Integer.parseInt(String.valueOf(s));
 }

 }

 @Override
 public void afterTextChanged(Editable s) {


 }
 });
</code></pre>

How to make a custom Data Picker like Date Picker in Android so that I can get data (int data) by custom input or by using the buttons (- &amp; +) so that it become easy for user to enter larger value !!
Has anyone any idea how to implement this?
please provide example, code snippet if possible.

I want to make like this
