NumericInputEdittext

Android EditText extension for validate numeric input values.

This library contains four main UI element :

IntegerInputEdittext
for integer input, set interval e.g. [ 0 , 100 ]
LongInputEdittext
for long input, set interval e.g. [ 50000l , 150000l ]
FloatInputEditText
for float value input, set interval e.g. ] 0f , 100f ]
DoubleInputEdittext
for double value input, set interval e.g. ] 0d , 1000000000d ]

Features

Set interval for valid numeric input from attribute string.
Get value directly from EditText with one line
Validate with one line
Autocorrect the values

How to use

Set the interval:

    IntegerInputEditText et_Int = (IntegerInputEditText) findViewById(R.id.et_intinput);
    et_Int.setValidInterval("[0,50]")

Validate, show error messages, and autocorrect the wrong value:

    et_Int.setAutoCorrectOnError(true);
    et_Int.setShowMessageOnError(true);
    boolean isInputValueValid = et_Int.isValid();

Get value directly from Edittext:

    Integer result = et_Int.getValue();

You can also specify the parameters from layout:

  <com.theophrast.forgivingui.numericinputedittext.ui.IntegerInputEditText
        xmlns:numericinput="http://schemas.android.com/apk/res-auto"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/et_intinput"
        numericinput:show_message_on_error="true"
        numericinput:autocorrect_on_error="true"
        numericinput:valid_range="[0,100]"
        ></com.theophrast.forgivingui.numericinputedittext.ui.IntegerInputEditText>

To float value input use this:

   <com.theophrast.forgivingui.numericinputedittext.ui.FloatInputEditText
        xmlns:numericinput="http://schemas.android.com/apk/res-auto"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/et_floatinput"
        numericinput:show_message_on_error="true"
        numericinput:autocorrect_on_error="true"
        numericinput:correction="0.1"
        numericinput:valid_range="]0f,1f]"
        ></com.theophrast.forgivingui.numericinputedittext.ui.FloatInputEditText>

Check the sample for more details.

Gradle

    dependencies{
        ...
        compile 'com.theophrast.forgivingui.numericinputedittext:numericinputedittext:1.0.2'
    }

Interval set

The valid interval of a NumericInputEditText can be specified with a String.
Use [valueMin , valueMax ] brackets to include the endpoints of the interval,
or use ]valueMin , valueMax[ brackets to exclude them.
You can also combine the brackets.
Examples:
>
[ minimum_enabled_value , maximum_enabled_value ]
or
] minimum_not_enabled_value , maximum_not_enabled_value [
or
] minimum_not_enabled_value , maximum_enabled_value ]
or
[ minimum_enabled_value , maximum_not_enabled_value [

Examples for interval set

Input interval for Dice rolling (int):

Enabled values are 1, 2, 3, 4, 5 and 6.

String interval = "[1,6]"

from layout.xml:

        numericinput:valid_range="[0,100]"

Input interval for a material temperature in laboratory (float - °C):

Enabled values are from ‒273,15f to positive infinite

String interval = "[‒273,15f,+["

Input interval for measured length (float):

In this case the enabled values are positive float numbers without maximum limit, but

0f value is not enabled.

String interval = "]0,+["
