如何处理ImeOptions的完成按钮单击？

Question

我在一个EditText地方设置以下属性，以便当用户单击EditText时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。

从屏幕键盘上击中完成按钮时，我该如何跟踪？

Answer 1

我最终得到了罗伯茨和基拉格答案的结合：((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： 上面的代码有时会两次激活回调。相反，我选择了以下代码，这些代码是从Google聊天客户端获得的：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;}

试试这个，它应该可以满足您的需求：editText.setOnEditorActionListener(new EditText.OnEditorActionListener() {    @Override    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {    if (actionId == EditorInfo.IME_ACTION_DONE) {       //do here your stuff f       return true;    }    return false;    } });
