Android setOnEditorActionListener()不会触发
我试图设置一个监听器来确定EditText
何时按下输入按钮,但是根本没有触发。我在装有Android 4.2.2的LG Nexus
4上进行了测试。setOnEditorActionListener
可以在具有Android 2.3的Amazon Kindle
Fire上使用,并且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;
}
});
我究竟做错了什么?我怎样才能解决这个问题?
回答:
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("TEST RESPONSE", "Enter was pressed");
}
}
});
