添加的EditText单选按钮旁边 [英] Adding EditText alongside RadioButton

问题描述

我有一个自定义的对话preference 子类中，我想有一个 RadioGroup中三单选按钮。前两个是香草单选带标题的组件，但我想放在第三的的EditText 直接到正确的就那么被选中的按钮时，我可以输入自定义值。

I have a custom DialogPreference subclass in which I would like to have a RadioGroup with three radio buttons. The first two are vanilla RadioButton components with titles, but for the third I would like to place an EditText directly to the right of it so I can enter a custom value when that button is selected.

我试图把第三个按钮为水平的LinearLayout 沿的EditText 但随后的第三个按钮的功能不参加父 RadioGroup中了。

I have tried putting the third button into a horizontal LinearLayout along with the EditText but then the third button does not participate in the parent RadioGroup anymore.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="match_parent">
    <RadioGroup
            android:id="@+id/lactate_radio"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >

        <RadioButton
                android:id="@+id/lactate_default_value"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/lactate_default_value"/>

        <RadioButton
                android:id="@+id/lactate_calibrated_value"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/lactate_calibrated_value" />
        <LinearLayout android:orientation="horizontal"
                      android:layout_width="match_parent"
                      android:layout_height="wrap_content">
            <RadioButton
                    android:id="@+id/lactate_custom_value"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="@string/lactate_custom_value"/>

            <EditText
                    android:id="@+id/lactate_custom_value_edit_text"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"/>

        </LinearLayout>
    </RadioGroup>
</LinearLayout>

我也尝试添加该的LinearLayout 编程，但仍然有相同的行为。有什么办法通过明确告诉父 RadioGroup中关于第三个按钮或通过某种方式定位的EditText 适当地不使用水平的LinearLayout ？否则，我想我会写一个单选子类，应该是一个真正的政党！

I have also tried adding this LinearLayout programmatically but still had the same behavior. Is there any way to do this, perhaps by explicitly telling the parent RadioGroup about the third button or by somehow positioning the EditText appropriately without using a horizontal LinearLayout? Otherwise, I think I'll have to write a RadioButton subclass which ought to be a real party!

推荐答案

您应该能够改变你的父布局，以 RelativeLayout的。然后给你的 RadioGroup中

You should be able to change your parent layout to RelativeLayout. Then give your RadioGroup

android:orientation="vertical"

然后把你的的EditText 旁边和的 RadioGroup中底部对齐。我还没有尝试过，但这样的事情应该工作。

then place your EditText next to and aligned with the bottom of the RadioGroup. I haven't tried it but something like this should work.

更新

我有时间来检验。这似乎给您正在寻找

I got time to test it. This seems to give the output you are looking for

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"
          android:layout_width="match_parent"
          android:layout_height="match_parent">
<RadioGroup
        android:id="@+id/lactate_radio"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >

    <RadioButton
            android:id="@+id/lactate_default_value"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="lactate_default_value"/>

    <RadioButton
            android:id="@+id/lactate_calibrated_value"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="lactate_calibrated_value" />
        <RadioButton
                android:id="@+id/lactate_custom_value"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="lactate_custom_value"/>
    </RadioGroup>

        <EditText
            android:id="@+id/lactate_custom_value_edit_text"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBottom="@+id/lactate_radio"
            android:layout_toRightOf="@+id/lactate_radio"
            android:text="Test Text" />
</RelativeLayout>

请注意，我也改变了一些宽度 S与 WRAP_CONTENT 所以它会结合在一起。更改定位的 RadioGroup中垂直省去了在的LinearLayout

Note that I also changed some of the widths to wrap_content so it would fit together. Changing the orientation of the RadioGroup to vertical eliminates the need for the LinearLayout
