点击一个按钮后更改键盘布局 [英] change the keyboard layout after a button click

问题描述

我的深化发展Android应用程序，和我有一个的EditText 和两单选按钮（ A 和乙），

I'm developping an android app , and i have an EditText and a two RadioButtons (A and B ),

我想要做的是：

当被选中单选 A，我想改变键盘布局完成按钮来显示它，
当单选 B被选中，我想改变键盘布局与搜索按钮来显示它。

When RadioButton A is checked , i want to change the keyboard layout to display it with the Done button , When the RadioButton B is checked, i want to change the keyboard layout to display it with the Search Button .

我试图改变的 IMEOptions 我的的EditText 这样的，但它仍然无法正常工作

I've tried to change the IMEOptions of my EditText like this , but it still doesn't work :

注：键盘已经可见，我想要做的只是修改按钮的搜索与按钮的完成两个<$ C $每个案件C>单选按钮

NB : the keyboard is already visible, what i want to do is just modify the button Search with the button Done in each case of the two radioButtons

@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    if(btnA.isChecked() ) { 
        txtSearch.setImeOptions(EditorInfo.IME_ACTION_DONE);
//      txtSearch.invalidate(); 
    }
    else {
        txtSearch.setImeOptions(EditorInfo.IME_ACTION_SEARCH);
//      txtSearch.invalidate();
    }   
}

有关如何做到这一点任何想法？

any ideas about how to do that ??

先谢谢了。

推荐答案

什么Android版本，你定位？我无法发表评论对不起（新帐户），但我目前正在做一个测试用例来回答你的问题。

What Android version are you targeting? I'm unable to post a comment sorry (new account), but am currently doing up a testcase to answer your question.

编辑：确定，我已经想通了。有点谷歌搜索（见这个问题）和编码后，我发现该imeOptions出现要被缓存/捆绑到输入法。我不知道这是否是一个错误或故意功能。要切换键盘当用户点击任一单选按钮，首先确保inputType下设置为您的EditText（的android：inputType下=TEXT），那么请使用以下你的的onCreate 方法：

Ok, I've figured it out. After a bit of googling (see this issue) and coding, I found that the imeOptions appear to be cached/tied to the input method. I'm not sure if this is a bug or intentional functionality. To switch the keyboard when the user taps either radio button, first make sure the inputType is set for your EditText (android:inputType="text"), then use the following in your onCreate method:

final RadioGroup btn_group = (RadioGroup) findViewById(R.id.btn_group);
final RadioButton btnA = (RadioButton) findViewById(R.id.btnA);
final RadioButton btnB = (RadioButton) findViewById(R.id.btnB);

btn_group.setOnCheckedChangeListener(new OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {
        final EditText txtSearch = (EditText) findViewById(R.id.edit_text);

        txtSearch.setInputType(InputType.TYPE_NULL);

        if(btnA.isChecked()) {
            txtSearch.setImeOptions(EditorInfo.IME_ACTION_DONE);
        } else {
            txtSearch.setImeOptions(EditorInfo.IME_ACTION_SEARCH);
        }

        txtSearch.setInputType(InputType.TYPE_CLASS_TEXT);
    }
});

请注意归零并重新设置inputType下的。

Note the nulling out and re-setting of the InputType.

最后，请注意，许多流行的键盘实现不给一个该死的你设置 imeOptions 来，所以不要依赖于你的应用程序这个功能。 Swype输入例如;

Finally, please be aware that many popular keyboard implementations don't give a damn what you set the imeOptions to, so don't rely on this functionality in your app. Swype for example;

在结论（见我做什么呢？），也不甘示弱，我已经捆绑了我的测试程序。你可以在这里找到它：<一href=\"http://dl.dropbox.com/u/52276321/ChangeKeyboardTest.zip\">http://dl.dropbox.com/u/52276321/ChangeKeyboardTest.zip

In conclusion (see what I did there?), not to be outdone, I've bundled up my test program. You can find it here: http://dl.dropbox.com/u/52276321/ChangeKeyboardTest.zip
