安卓的EditText ImeOptions＆QUOT;完成＆QUOT;赛道完成打字

问题描述

我有一个EditText场我在哪里设置以下属性，这样我可以显示键盘上的完成按钮，当用户点击文本框。

I am having an edittext field where I am setting the following property so that I can display the done button on the keyboard when user click on the textfield.

editText.setImeOptions(EditorInfo.IME_ACTION_DONE);

当用户点击屏幕键盘（输入完成）完成按钮我想换一个单选按钮的状态，我怎么可以跟踪完成按钮当它从屏幕键盘打？

When user clicks the done button on the screen keyboard(finish typing) I want to change a radio button state, how can I track done button when it is hit from screen keyboard ?

推荐答案

我结束了罗伯茨的组合，chirags答案：

I ended up with a combination of Roberts and chirags answers:

((EditText)findViewById(R.id.search_field)).setOnEditorActionListener(
        new EditText.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        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 false;
    }
});

更新：上述code将一些次激活回调的两倍。相反，我选择了以下code，这是我从谷歌聊天客户端有：

Update:The above code would some times activate the callback twice. Instead I've opted for the following code, which I got from the Google chat clients:

public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
    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;
}
