Question

我想知道的是我在运行时或在编辑文本中编写内容时所写的内容，或者只是想知道我在软键盘中单击了什么内容。

我使用了onKeUp方法，但只有在我按Enter或取消按钮时，它才起作用

 @Override
public boolean onKeyUp(int keyCode, KeyEvent event) {

    switch (keyCode) {

        case KeyEvent.keyCodeFromString():
            if (event.isShiftPressed()) {
                Log.i("sandeep","1");
            } else {
                Log.i("sandeep","2");
            }
            return true;
        case KeyEvent.KEYCODE_K:
            if (event.isShiftPressed()) {
                Log.i("sandeep","3");
            } else {
                Log.i("sandeep","4");
            }
            return true;
        default:
            Log.i("sandeep","5");
            return super.onKeyUp(keyCode, event);
    }
}

Answer 1

为此14 correct_answer 15 correct_answer2 16 correct_answer2 17 correct_answer实施此addTextChangedListener

将此代码添加到您的EditText或onCreate()类的activity中

fragment

这有助于您在运行时找出editText.addTextChangedListener(new TextWatcher() { @Override public void afterTextChanged(Editable s) { //do your stuff here } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { //do your stuff here } });中已更改的文本

Answer 2

我认为您正在寻找_tcpListener.ExclusiveAddressUse = false;

EditorActionListener

如何知道我在运行时用editText编写的内容？
