Disable Enter in editText android

问题:

I have a EditText but I want only one line. I put lime this

       <item name="android:maxLines">1</item>
        <item name="android:minLines">1</item>
        <item name="android:lines">1</item>

but doesn't work.

See my code:

<LinearLayout style="@style/linearInputEntryText">
                <LinearLayout  style="@style/subLinearLayout">
                    <TextView style="@style/label" android:text="Last Name" android:id="@+id/textView2"/>
                    <EditText style="@style/editTextEntryName" android:id="@+id/lastName"/>
                </LinearLayout>
                <View style="@style/linearInputEntryBlack" > </View>
            </LinearLayout>

and styles:

    <style name="editTextEntryName" parent="editTextEntry">
    <item name="android:maxLines">1</item>
    <item name="android:minLines">1</item>
    <item name="android:lines">1</item>
    <item name="android:layout_gravity">left</item>
</style>

回答1:

Because of different Android versions, the best practice is to include these parameters at the same time:

<item name="android:maxLines">1</item>
<item name="android:lines">1</item>
<item name="android:singleLine">true</item>

If you don't, it will not work correctly on some devices.

回答2:

Please use

android:singleLine="true"

instead of

    <item name="android:maxLines">1</item>
    <item name="android:minLines">1</item>
    <item name="android:lines">1</item>

That single attribute is enough to make your EditText accept only one line of text and disable the enter button.

UPDATE

Don't worry about this comment,

android:singleLine is deprecated it's not a good practice using it

This attributed is officially supported and is not deprecated in any possible way. And it is also guaranteed that this will work in all devices and on all Android versions.

回答3:

android:maxLines="1" allows the text to be multiline but limits the height of edittext to display a single line.

If you want to disable the enter (new line) key, set the input type to text

    android:inputType="text"

回答4:

You may use

<EditText 
   ......
   android:imeOptions="actionNext" OR "actionDone" />

回答5:

Use android:singleLine=true instead android:maxLines=1

Please read about singleLine

回答6:

use android:singleLine="true" property

     <EditText 
       ......
       android:singleLine="true"
       android:id="@+id/lastName"/>

Or if you wanna use java you could do this:

    edittext1.setSingleLine();
