java - Android setOnEditorActionListener() 不触发

Question

我正在尝试在按下输入按钮时为 EditText 设置一个监听器。但它根本没有触发。我在装有 Android 4.2.2 的 LG Nexus 4 上对此进行了测试。 setOnEditorActionListener 适用于 Android 2.3 的 Amazon Kindle Fire 而 setImeActionLabel 无处可用!我也无法为 Enter 按钮设置文本。这是代码:

mEditText.setImeActionLabel("Reply", EditorInfo.IME_ACTION_UNSPECIFIED);
mEditText.setOnEditorActionListener(new OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId,
                KeyEvent event) {
            Log.d("TEST RESPONSE", "Action ID = " + actionId + "KeyEvent = " + event);
            return true;
        }  
    });

我做错了什么？我该如何解决这个问题？

您可以使用 TextWatcher .

editText.addTextChangedListener(new TextWatcher() {
    
    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
    }
        
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }
        
    @Override
    public void afterTextChanged(Editable s) {
        if (s.charAt(s.length() - 1) == '\n') {
              Log.d("TAG", "Enter was pressed");
        }
    }
});
