java – Android setOnEditorActionListener()不会触发

当我按下输入按钮时,我正试图设置一个侦听器到EditText.但它根本没有触发.我使用Android 4.2.2在LG Nexus 4上进行了测试. setOnEditorActionListener适用于安卓2.3的亚马逊Kindle Fire,而setImeActionLabel无处可行！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;
        }  
    });

我究竟做错了什么？我怎样才能解决这个问题？

解决方法:

你可以使用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("TEST RESPONSE", "Enter was pressed");
            }
        }
    });
