android - 如何处理 ImeOptions 的完成按钮点击？

Question

我有一个 EditText 我正在设置以下属性，以便当用户单击 EditText 时我可以在键盘上显示完成按钮。

editText.setImeOptions(EditorInfo.IME_ACTION_DONE);

当用户单击屏幕键盘上的完成按钮(完成输入)时，我想更改 RadioButton 状态。

如何在屏幕键盘点击完成按钮时跟踪它？

我最终得到了 Roberts 和 chirags 的组合答案:

((EditText)findViewById(R.id.search_field)).setOnEditorActionListener(
        new EditText.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        // Identifier of the action. This will be either the identifier you supplied,
        // or EditorInfo.IME_NULL if being called due to the enter key being pressed.
        if (actionId == EditorInfo.IME_ACTION_SEARCH
                || actionId == EditorInfo.IME_ACTION_DONE
                || event.getAction() == KeyEvent.ACTION_DOWN
                && event.getKeyCode() == KeyEvent.KEYCODE_ENTER) {
            onSearchAction(v);
            return true;
        }
        // Return true if you have consumed the action, else false.
        return false;
    }
});

更新:上面的代码有时会激活回调两次。相反，我选择了从 Google 聊天客户端获得的以下代码:

public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
    // If triggered by an enter key, this is the event; otherwise, this is null.
    if (event != null) {
        // if shift key is down, then we want to insert the '\n' char in the TextView;
        // otherwise, the default action is to send the message.
        if (!event.isShiftPressed()) {
            if (isPreparedForSending()) {
                confirmSendMessageIfNeeded();
            }
            return true;
        }
        return false;
    }

    if (isPreparedForSending()) {
        confirmSendMessageIfNeeded();
    }
    return true;
}
