Set EditText Program Codes

Question

I am essentially trying to programmatically set a digit value in an EditText. So far I:

weightInput.setInputType(InputType.TYPE_CLASS_PHONE); weightInput.setKeyListener(DigitsKeyListener.getInstance()); 

This is good, but I also want to be able to use decimal place (.). Any ideas?

Answer 1

Try the following:

 <EditText android:inputType="number" android:digits="0123456789." /> 

From the code:

 weightInput.setKeyListener(DigitsKeyListener.getInstance("0123456789.")); 

But, this allows the user to include a few "." See Muffinbubble Answer for real numbers.

Answer 2

Try the following:

 weightInput.setInputType(InputType.TYPE_CLASS_NUMBER); weightInput.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL); weightInput.setKeyListener(DigitsKeyListener.getInstance(false,true)); 

---

 public static DigitsKeyListener getInstance (boolean sign, boolean decimal) 

Returns a DigitsKeyListener that accepts digits from 0 to 9, plus a minus sign (only at the beginning) and / or a decimal point (only one per field), if specified.

This solves the problem of many ".". in EditText

Answer 3

Use InputType.TYPE_NUMBER_FLAG_DECIMAL .

To enter an IP address (multiple dots and numbers)

 <EditText android:id="@+id/ipBox" android:layout_width="fill_parent" android:layout_height="wrap_content" android:hint="@string/ipAddrHint" android:inputType="numberDecimal|number" android:digits="0123456789." android:textSize="30sp" />
