你可以用这种方法

editText.setOnEditorActionListener((v, actionId, event) -> {
       if (actionId == EditorInfo.IME_ACTION_DONE) {
          // Do some things      
          return true;
       }
       return false;
});

你可以在那里看到行动清单。

例如:

IME_ACTION_GO

IME_ACTION_SEARCH

IME_ACTION_SEND

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;
        }
    });

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;
        }
    });

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)

添加这些依赖项，应该可以工作:

import android.view.KeyEvent;
import android.view.View;
import android.widget.EditText;

   final EditText edittext = (EditText) findViewById(R.id.edittext);
    edittext.setOnKeyListener(new OnKeyListener() {
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            // If the event is a key-down event on the "enter" button
            if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
                    (keyCode == KeyEvent.KEYCODE_ENTER)) {
                // Perform action on key press
                Toast.makeText(HelloFormStuff.this, edittext.getText(), Toast.LENGTH_SHORT).show();
                return true;
            }
            return false;
        }
    });
