Android: Limiting EditText to numbers

问题

When creating an EditText in the java portion of the application, how do you limit it to numbers like you would in the xml? For example:

new EditText(this);

set like

<EditText
    android:id="@+id/h1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:inputType="numberDecimal"/>

回答1:

Something like this perhaps ?

EditText text = new EditText(this);
text.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL);

回答2:

Use of android:numeric is deprecated, use android:inputType=number

回答3:

Go to the docs and look at the table with XML attributes. It shows you the code equivalent of each item.

In this case, it's setRawInputType.

回答4:

this will usually do it:

android:numeric="integer"

回答5:

Simply use the below lines in the xml file

To accept only Numbers put:

 android:inputType="number"

To limit the length of the input numbers:

android:maxLength="10"

To accept only specific numbers:

EX:1 The below line accept only 1 or 0.

android:digits="10"

EX:2 The below line accept only 2 or 3.

android:digits="23"
