*I have done this in the past with `android:singleLine="true"` and then adding a listener for the "enter" key:* **我过去使用`android:singleLine="true"`完成此操作，然后为“ enter”键添加了一个侦听器：**

((EditText)this.findViewById(R.id.mytext)).setOnKeyListener(new OnKeyListener() {
    
        public boolean onKey(View v, int keyCode, KeyEvent event) {
    
            if (event.getAction() == KeyEvent.ACTION_DOWN && keyCode == KeyEvent.KEYCODE_ENTER) {
                //if the enter key was pressed, then hide the keyboard and do whatever needs doing.
                InputMethodManager imm = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(getApplicationWindowToken(), 0);
    
                //do what you need on your enter key press here
    
                return true;
            }
    
            return false;
