如何对齐此引导单选按钮？(How to align this bootstrap radio button?)

 PAGE就在这里 
 

 我使用以下代码创建单选按钮，按钮和文本彼此相邻。 这很好，但它不是垂直中间对齐文本输入字段，它放在单选按钮上。 
 

<div class="col-md-3">
    <div id="edit-donation-frequent" class="form-radios form-group">
        <div class="form-item form-type-radio form-item-donation-frequent">
            <input type="radio" id="edit-donation-frequent-monthly" name="donation_frequent" value="monthly" class="form-radio" />  
            <label class="option font-size-sixteen" for="edit-donation-frequent-monthly">Monthly</label>
         </div>
    </div>
</div>
<div class="col-md-3">
    <div class="form-item form-type-radio form-item-donation-frequent form-group">
        <input type="radio" id="edit-donation-frequent-once" name="donation_frequent" value="once" class="form-radio" />  
        <label class="option font-size-sixteen" for="edit-donation-frequent-once">One time </label>
    </div>
</div>

 我把.form-item label.option { vertical-align: middle; } 但仍然是相同的结果。 然后我尝试了margin-top和其他一些CSS样式，但无法得到我想要的东西。 
 

 我想要两个单选按钮（每月，一次和固定电话）看起来像下面的截图。 在此处输入图像描述

I created radio button using following code and the button & the text comes next to each other. That's fine but it is not VERTICALLY middle aligned to the text input field which is placed left to the radio button.
 

<div class="col-md-3">
    <div id="edit-donation-frequent" class="form-radios form-group">
        <div class="form-item form-type-radio form-item-donation-frequent">
            <input type="radio" id="edit-donation-frequent-monthly" name="donation_frequent" value="monthly" class="form-radio" />  
            <label class="option font-size-sixteen" for="edit-donation-frequent-monthly">Monthly</label>
         </div>
    </div>
</div>
<div class="col-md-3">
    <div class="form-item form-type-radio form-item-donation-frequent form-group">
        <input type="radio" id="edit-donation-frequent-once" name="donation_frequent" value="once" class="form-radio" />  
        <label class="option font-size-sixteen" for="edit-donation-frequent-once">One time </label>
    </div>

I put .form-item label.option { vertical-align: middle; } but still the same result. Then I tried margin-top and some other css styles but could not get what I want.

最满意答案

 您需要在对话框中设置OnKeyListener并检查是否按下了后退键。 
 

 以下是适合您需要的示例代码，您需要修改代码，如下所示： 
 

AlertDialog alertDialog = new AlertDialog.Builder(this,R.style.myBackgroundStyle).create();
        alertDialog.setTitle("Exit Alert");
        alertDialog.setMessage("Do you really want to exit the Game?");
        alertDialog.setButton("Quit", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                //Best way is firstly use finish() and after that use System.exit(0) to clear static variables. It will give you some free space.
                // A lot of applications leave working processes and variables what makes me angry. After 30 minutes of using memory is full and i have to run Task Manager - Lvl 2 clear memory
                finish();
                System.exit(0);
                return;

            }
        });


//New part regarding the back key when only dialog is shown.
alertDialog.setOnKeyListener(new Dialog.OnKeyListener() {

        @Override
        public boolean onKey(DialogInterface arg0, int keyCode,
                KeyEvent event) {

            if (keyCode == KeyEvent.KEYCODE_BACK) {

                alertDialog.dismiss();
            }
            return true;
        }
    });

 

 这只有在显示对话框时才有效，因此，您可以返回到您的活动 

You need to set an OnKeyListener to your dialog and check whether back key is pressed. 
 

Here is a sample code that suits your need, you need to modify your code as follows: 
 

AlertDialog alertDialog = new AlertDialog.Builder(this,R.style.myBackgroundStyle).create();
        alertDialog.setTitle("Exit Alert");
        alertDialog.setMessage("Do you really want to exit the Game?");
        alertDialog.setButton("Quit", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                //Best way is firstly use finish() and after that use System.exit(0) to clear static variables. It will give you some free space.
                // A lot of applications leave working processes and variables what makes me angry. After 30 minutes of using memory is full and i have to run Task Manager - Lvl 2 clear memory
                finish();
                System.exit(0);
                return;

            }
        });


//New part regarding the back key when only dialog is shown.
alertDialog.setOnKeyListener(new Dialog.OnKeyListener() {

        @Override
        public boolean onKey(DialogInterface arg0, int keyCode,
                KeyEvent event) {

            if (keyCode == KeyEvent.KEYCODE_BACK) {

                alertDialog.dismiss();
            }
            return true;
        }
    });

 

this will work only when the dialog is shown, therefore, you would be able to return to your activity
