你也可以做到。

editText.setOnKeyListener(new OnKeyListener() {

            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event)
            {
                if (event.getAction() == KeyEvent.ACTION_DOWN
                        && event.getKeyCode() ==       KeyEvent.KEYCODE_ENTER) 
                {
                    Log.i("event", "captured");

                    return false;
                } 

            return false;
        }
    });

这个问题还没有被Butterknife回答

布局的XML

<android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/some_input_hint">

        <android.support.design.widget.TextInputEditText
            android:id="@+id/textinput"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:imeOptions="actionSend"
            android:inputType="text|textCapSentences|textAutoComplete|textAutoCorrect"/>
    </android.support.design.widget.TextInputLayout>

JAVA应用程序

@OnEditorAction(R.id.textinput)
boolean onEditorAction(int actionId, KeyEvent key){
    boolean handled = false;
    if (actionId == EditorInfo.IME_ACTION_SEND || (key.getKeyCode() == KeyEvent.KEYCODE_ENTER)) {
        //do whatever you want
        handled = true;
    }
    return handled;
}

这应该可以

input.addTextChangedListener(new TextWatcher() {

           @Override
           public void afterTextChanged(Editable s) {}

           @Override    
           public void beforeTextChanged(CharSequence s, int start,
             int count, int after) {
           }

           @Override    
           public void onTextChanged(CharSequence s, int start,
             int before, int count) {
               if( -1 != input.getText().toString().indexOf( "\n" ) ){
                   input.setText("Enter was pressed!");
                    }
           }
          });

在编辑器中键入这段代码，以便它可以导入必要的模块。

 query.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView textView, int actionId, KeyEvent keyEvent) {
            if(actionId == EditorInfo.IME_ACTION_DONE
                    || keyEvent.getAction() == KeyEvent.ACTION_DOWN
                        || keyEvent.getAction() == KeyEvent.KEYCODE_ENTER) {

                // Put your function here ---!

                return true;

            }
            return false;
        }
    });

Kotlin解决方案的反应进入按使用Lambda表达式:

        editText.setOnKeyListener { _, keyCode, event ->
            if(keyCode == KeyEvent.KEYCODE_ENTER && event.action==KeyEvent.ACTION_DOWN){
            //react to enter press here
            }
            true
        }

不做额外的检查类型的事件将导致这个监听器被调用两次时按一次(一次为ACTION_DOWN，一次为ACTION_UP)

好吧，如果这些答案都对你不起作用，你还没生气，我有一个解决办法。 使用AppCompatMultiAutoCompleteTextView(是的!)而不是EditText与以下代码(kotlin)

val filter = InputFilter { source, start, end, _, _, _ ->
        var keepOriginal = true
        val sb = StringBuilder(end - start)
        for (i in start until end) {
            val c = source[i]
            if (c != '\n')
                sb.append(c)
            else {
                keepOriginal = false
                //TODO:WRITE YOUR CODE HERE
            }
        }
        if (keepOriginal) null else {
            if (source is Spanned) {
                val sp = SpannableString(sb)
                TextUtils.copySpansFrom(source, start, sb.length, null, sp, 0)
                sp
            } else {
                sb
            }
        }
    }

appCompatMultiAutoCompleteTextView.filters = arrayOf(filter);

它(可能)适用于所有设备，我在android 4.4和10上测试了它。它在小米中也起作用。 我他妈的♥机器人:)
