Android Calculator - Editview Cannot Input Decimal Places

I am new to Android code development...I am developing a Android calculator apps and does not understand why the two EditTexts (first input and second input) cannot accept decimal

Solution 1:

If you want to use Decimal Number only on your EditText

use the xml attribute android:inputType="numberDecimal" in your EditText widget your EditText declaration will be like this:

<EditText
    android:id="@+id/editText1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ems="10"
    android:inputType="numberDecimal" />

If you want to use Signed Decimal Number than combine the two Xml attributes android:inputType="numberDecimal" and android:inputType="numberSigned". Your EditText declaration will be like this:

<EditTextandroid:id="@+id/editText1"android:layout_width="match_parent"android:layout_height="wrap_content"android:ems="10"android:inputType="numberDecimal|numberSigned" ></EditText>

Solution 2:

Change android:inputType from "number" to "numberDecimal". See the documentation for even more options for inputType.

Solution 3:

inputType="number" doesnt allow floats. try changing:

android:inputType="number"

to:

android:numeric="integer|decimal"

Solution 4:

You need to change the input type of your EditText in the XML code.

Change the inputType attribute of the EditText from

android:inputType="number"

to

android:inputType="numberDecimal"

<EditText 
            android:layout_height="wrap_content" 
            android:layout_width="fill_parent" 
            android:inputType="numberDecimal" 
            android:id="@+id/txtOpd1"/>
