How can EditText accept only integer or float value?

Use Java

for input both integer and float
edit.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL);

for input only integer
edit.setInputType(InputType.TYPE_CLASS_NUMBER);

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:

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

</EditText>
