Is there a default Android view widget with textbox and 2 knobs? - android-layout

Question

Is there a default view that allows a number textbox, which can be changed by typing in the textbox or by two adjacent knobs by the textbox. So basically, in awesome ASCII graphics:
[<] [textbox] [>]
Basically an increment button, textbox, and decrement button.

Answer 1

Since API level 11, you can now use the NumberPicker;
You can find the documentation here
You can find an example here

Answer 2

My custom solution using EditText and two Button objects:
// This is a textbox group with two knob buttons
LinearLayout boxGroup = new LinearLayout(this);
boxGroup.setOrientation(LinearLayout.HORIZONTAL);
//Stores the current value in the textbox
final int[] value = {0};
// Editable text box
final EditText editText = new EditText(this);
editText.setText("" + value[0]);
// Decrement button
Button decrementButton = new Button(this);
decrementButton.setText("<");
decrementButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
value[0]++;
editText.setText("" + value[0]);
}
});
// Increment button
Button incrementButton = new Button(this);
incrementButton.setText(">");
incrementButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
value[0]--;
editText.setText("" + value[0]);
}
});
boxGroup.addView(decrementButton);
boxGroup.addView(editText);
boxGroup.addView(incrementButton);
