如何以编程方式隐藏/禁用 Android 软键盘上的表情符号

Question

Is it possible to hide a specific keyboard button? I have an EditText and on some devices its keyboard has smiley faces while on other devices it is missing. I want to hide it on all devices.

Below is the XML for my EditText :

android:id="@+id/text_editor"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignWithParentIfMissing="true"
android:layout_centerVertical="true"
android:layout_toLeftOf="@+id/send_side"
android:hint="Enter your text"
android:imeOptions="actionSend|flagNoEnterAction"
android:inputType="textLongMessage|textAutoCorrect|textCapSentences|textMultiLine"
android:maxLength="1000"
android:maxLines="3"
android:nextFocusRight="@+id/send_button"
android:padding="12dp"
android:textSize="13sp"

Is this possible?

Answer 1

I found something in " Disabling smiley key on keyboards with the stock messaging app in ICS ".

You need to remove the textLongMessage option from the inputType .

You will still have the ":-)" button on most keyboards, but not the emoji.

Answer 2

(For completeness sake)

This solution is for people who need to have textview without the smiley on their soft keyboard. @Adrian's solution, to use email address type, works but it will show unnecessary '@' and '.com' buttons on your keyboard. I tried several combinations of InputType and the best solution IMHO is this:

mTextView.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);

这在 Android 4.4.2 上对我有用

android:inputType="textEmailAddress|textMultiLine"

Answer 4

From Petr Daña in a similar question... This enables autocomplete and disables all the smileys.

InputFilter filter = new InputFilter() {
@Override
public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
    for (int i = start; i < end; i++) {
        int type = Character.getType(source.charAt(i));
        //System.out.println("Type : " + type);
        if (type == Character.SURROGATE || type == Character.OTHER_SYMBOL) {
            return "";
        }
    }
    return null;
    }
};

mMessageEditText.setFilters(new InputFilter[]{filter});

Refer to " How to detect emoticons in EditText in android ".

I tried @Adrian's solution, but it has "@" and ".com" keys. I just need a field that can take user's name. I got my solution by combining textVisiblePassword and textNoSuggestions :

android:inputType="textVisiblePassword|textNoSuggestions

Answer 6

mEditText.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD| TEXT_MULTILINE);
