There is nothing that will 100% disable emoji. The keyboard can act to any mode it sees in whatever way it thinks best, so there is no setting that will prevent emoji. If you must prevent it, do it by white or blacklisting characters with a TextWatcher.

There is tricky way for disabling emoji from keyboard..

you just have to set 

<code>android:inputType="textEmailAddress"</code>

for <code>EditText</code>..

<pre><code> &lt;EditText
 android:id="@+id/edt_note"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:hint="@string/note"
 android:inputType="textEmailAddress"
 android:padding="10dp"
 android:textColor="@color/white" /&gt;
</code></pre>

I am not sure that it will work in all cases but in my case it worked for me...

Another solution:

mEtMessageText.setInputType(InputType.TYPE_TEXT_VARIATION_EMAIL_ADDRESS | InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_MULTI_LINE);

In this example it shows the ENTER button

InputType.TYPE_TEXT_VARIATION_EMAIL_ADDRESS is equivalent to android:inputType="textEmailAddress" in XML layout

 if (! sourceOriginal.toString().equals(source.toString()))
 {
 char[] v = new char[end - start];
 TextUtils.getChars(source, start, end, v, 0);

 String s = new String(v);

 if (source instanceof Spanned)
 {
 SpannableString sp = new SpannableString(s);
 TextUtils.copySpansFrom((Spanned) source, start, end, null, sp, 0);
 return sp;
 }
 else
 {
 return s;
 }
 }
 else
 {
 return null; // keep original
 }
 }

 private String replaceEmoji(CharSequence source)
 {

 String notAllowedCharactersRegex = "[^a-zA-Z0-9@#\\$%\\&amp;\\-\\+\$\$\\*;:!\\?\\~`£\\{\\}\\[\\]=\\.,_/\\\\\\s'\\\"&lt;&gt;\\^\\|÷×]";
 return source.toString()
 .replaceAll(notAllowedCharactersRegex, "");
 }

 };
}
</code></pre>

Then set it as EditText filters;

<pre><code>InputFilter[] filterArray = new InputFilter[] {getEditTextFilterEmoji()}
editText.setFilters(filterArray);

<pre><code>dependencies{
 compile 'com.xw.repo:xedittext:2.0.0@aar'

</code></pre>

after that, in your layout.xml:

<pre><code>&lt;com.xw.repo.XEditText

 public CustomEditText(Context context, AttributeSet attrs) {

Code from @woxingxiao works great, until you specify any inputType in your xml, for example <code>android:inputType="textMultiLine"</code>.

I changed a little bit his proposal and I think it works great.

<pre><code>public class EmojiExcludeEditText extends EditText {

 private EmojiExcludeFilter emojiExcludeFilter;

 public EmojiExcludeEditText(Context context) {
 super(context);
 init();
 }

 public EmojiExcludeEditText(Context context, AttributeSet attrs) {

 init();
 }

 public EmojiExcludeEditText(Context context, AttributeSet attrs, int defStyleAttr) {
 super(context, attrs, defStyleAttr);
 init();
 }

 private void init() {
 if (emojiExcludeFilter == null) {
 emojiExcludeFilter = new EmojiExcludeFilter();
 }
 setFilters(new InputFilter[]{emojiExcludeFilter});
 }

 @Override
 public void setFilters(InputFilter[] filters) {
 if (filters.length != 0) { //if length == 0 it will here return when init() is called
 boolean add = true;
 for (InputFilter inputFilter : filters) {
 if (inputFilter == emojiExcludeFilter) {
 add = false;
 break;
 }
 }
 if (add) {
 filters = Arrays.copyOf(filters, filters.length + 1);
 filters[filters.length - 1] = emojiExcludeFilter;
 }
 }
 super.setFilters(filters);
 }

 private class EmojiExcludeFilter implements InputFilter {

 @Override
 public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
 for (int i = start; i &lt; end; i++) {
 int type = Character.getType(source.charAt(i));
 if (type == Character.SURROGATE || type == Character.OTHER_SYMBOL) {

There is value <code>digits</code> available in xml file for EditText. You can set there all acceptable chars.

<pre><code>&lt;EditText

 android:layout_height="match_parent"
 android:digits="qwertyuiopasdfghjklzxcvbnm 1234567890 QWERTYUIOPASDFGHJKLZXCVBNM" /&gt;

 return "";
 }
 }
 return null;
 }
 };
 return new InputFilter[]{EMOJI_FILTER};
 }
}
</code></pre>

And to disable emoji in edit text, do this:

<pre><code>editText.setFilters(EmojiFilter.getFilter());
</code></pre>

There were some emoji which were able to type so i added:

You can use input filter for removing un-wanted characters, Here I used ascci values for filtering.

<pre><code>public class CustomEditText extends AppCompatEditText {
private InputFilter unwantedCharacterFilter;

public CustomEditText(Context context) {
 super(context);
}

public CustomEditText(Context context, AttributeSet attrs) {
 super(context, attrs);
}

public CustomEditText(Context context, AttributeSet attrs, int defStyleAttr) {
 super(context, attrs, defStyleAttr);
}

private void init() {
 setFilters(new InputFilter[]{});
}
private InputFilter getUnwantedCharacterFilter() {
 if (null == unwantedCharacterFilter) {
 unwantedCharacterFilter = new InputFilter() {
 @Override
 public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
 if (!TextUtils.isEmpty(source)) {
 for (int index = start; index &lt; end; index++) {
 if (source.charAt(index) &lt; 0 || source.charAt(index) &gt; 177) {
 return "";
 }
 }
 }
 return null;
 }
 };
 }
 return unwantedCharacterFilter;
}

@Override
public void setFilters(InputFilter[] filters) {
 List&lt;InputFilter&gt; filterList = new ArrayList&lt;&gt;(Arrays.asList(filters));
 filterList.add(getUnwantedCharacterFilter());
 InputFilter specifiedFilters[] = filterList.toArray(new InputFilter[]{});
 super.setFilters(specifiedFilters);
}
</code></pre>

}

Emoji use area of Unicode with a range of code points from U+1F604 to U+1F539.
And Character.SURROGATE reserved the range is over the Emoji’s.
<pre><code>val EMOJI_FILTER =InputFilter { source, start, end, dest, dstart, dend -&gt;
 for (index in start until end) {
 val type = Character.getType(source[index])
 if (type == Character.SURROGATE.toInt()) {
 return@InputFilter &quot;&quot;
 }
 }
 null
 }


 etLintEdt.filters = arrayOf(EMOJI_FILTER)
</code></pre>

blocks|key|1709293|text|您可以使用"textVisiblePassword“作为输入类型。这将禁用键盘上的表情符号。然而，用户仍然可以将笑脸复制粘贴到编辑文本中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1709294|<EditText

You can use input type as &quot;textVisiblePassword&quot;. This will disable emojis from keyboard. However user can still copy-paste the smileys into the edit text.
<pre><code>&lt;EditText
 android:layout_width=&quot;match_parent&quot;
 android:layout_height=&quot;match_parent&quot;
 android:inputType=&quot;textVisiblePassword&quot; /&gt;
</code></pre>

blocks|key|1709303|text|为此，我做了Kotlin扩展。它还将防止Emoji的复制粘贴。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1709304|扩展名：|1709305|fun+EditText.filterEmoji()+{

++++})
}|code-block|syntax|javascript|1709306|在Kotlin类中：|1709307|editText.filterEmoji()|1709308|就这样。享受吧！|1709309|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|T|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|U|8|@]|9|@]|A|$G|H]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

I have made Kotlin Extension for this purpose. It will also prevent copy paste of Emoji.
Extension:
<pre><code>fun EditText.filterEmoji() {
 filters = arrayOf(InputFilter { source, _, _, _, _, _ -&gt;
 source.filter { Character.getType(it) != Character.SURROGATE.toInt() }
 })
}
</code></pre>
In Kotlin class:
<pre><code>editText.filterEmoji()
</code></pre>
That's it. Enjoy!

Most implementations of the <code>text</code> inputType (other than URI, password, etc.) for EditText and TextView allow Emoji - although in most Google keyboard configurations this button is hidden. Is there a way to disable Emoji from being entered in an EditText? Is there an inputType parameter that could be paired with <code>textMultiLine</code> that would disable Emoji?

text inputType的大多数实现( URI、密码等除外)对于EditText和TextView，允许使用表情符号--尽管在大多数谷歌键盘配置中，这个按钮是隐藏的。有没有办法禁止在EditText中输入表情符号？是否有一个可以与textMultiLine配对的inputType参数可以禁用Emoji？
