有什麼方法可以更改RadioButton的佈局,並且仍然讓RadioGroup識別它嗎?RadioButton的自定義佈局
我需要的是,佈局將包括幾個EditText字段,以便當用戶選擇該按鈕時,這些字段變爲活動狀態。 我知道我可以構建一個基於LinearLayout的自定義零件,並使用以下代碼設置我自己的佈局: (LinearLayout)LayoutInflater.from(context).inflate(R.layout.my_layout,this,true) 但無法弄清楚用單選按鈕做同樣的事情。
我已經嘗試過在RadioGroup之外添加額外字段並將它們與按鈕排列在一起的選項,但它根本無法使用。 它似乎太依賴於設備。
這是原來的佈局是什麼樣子:
<RadioGroup
android:id="@+id/time_selector_radio_group"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="@id/time_selector_hours_prompt"
android:layout_below="@id/time_selector_hours_prompt"
android:layout_alignParentRight="true"
android:gravity="right"
android:orientation="vertical"
android:checkedButton="@+id/time_selector_first_radio"
>
<RadioButton
android:id="@+id/time_selector_first_radio"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="1dip"
android:button="@drawable/radio_button_selector"
/>
<RadioButton
android:id="@+id/time_selector_second_radio"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="1dip"
android:button="@drawable/radio_button_selector"
/>
<RadioButton
android:id="@+id/time_selector_third_radio"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="1dip"
android:button="@drawable/radio_button_selector"
/>
<RadioButton
android:id="@+id/time_selector_hours_radio"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="1dip"
android:button="@drawable/radio_button_selector"
/>
</RadioGroup>
<TextView
android:id="@+id/time_selector_all_day_prompt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="@id/time_selector_radio_group"
android:layout_below="@id/time_selector_hours_prompt"
android:layout_marginTop="11dip"
android:text="@string/time_all_day"
/>
<TextView
android:id="@+id/time_selector_before_noon_prompt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="@id/time_selector_radio_group"
android:layout_below="@id/time_selector_all_day_prompt"
android:layout_marginTop="19dip"
android:text="@string/time_before_noon"
/>
<TextView
android:id="@+id/time_selector_after_noon_prompt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="@id/time_selector_radio_group"
android:layout_below="@id/time_selector_before_noon_prompt"
android:layout_marginTop="19dip"
android:text="@string/time_after_noon"
/>
<TextView
android:id="@+id/time_selector_starting_time_prompt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignRight="@id/time_selector_starting_date_prompt"
android:layout_below="@id/time_selector_after_noon_prompt"
android:layout_marginTop="20dip"
android:layout_marginLeft="2dip"
android:text="@string/advanced_time_selector_dialog_starting_time_prompt"
/>
<EditText
android:id="@+id/time_selector_starting_time"
android:layout_width="@dimen/advanced_time_selector_edit_texts_width"
android:layout_height="wrap_content"
android:layout_alignRight="@id/time_selector_starting_date"
android:layout_alignBaseline="@id/time_selector_starting_time_prompt"
android:textSize="14sp"
android:paddingRight="10dip"
android:paddingLeft="10dip"
android:gravity="center"
android:singleLine="true"
android:maxWidth="@dimen/advanced_time_selector_edit_texts_width"
android:background="@drawable/text_field_bg"
android:inputType="datetime"
/>
<TextView
android:id="@+id/time_selector_ending_time_prompt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignRight="@id/time_selector_ending_date_prompt"
android:layout_alignBottom="@id/time_selector_starting_time_prompt"
android:layout_alignBaseline="@id/time_selector_starting_time_prompt"
android:layout_marginRight="2dip"
android:layout_marginLeft="2dip"
android:text="@string/ending_date_prompt"
/>
<EditText
android:id="@+id/time_selector_ending_time"
android:layout_width="@dimen/advanced_time_selector_edit_texts_width"
android:layout_height="wrap_content"
android:layout_alignRight="@id/time_selector_ending_date"
android:layout_alignBaseline="@id/time_selector_ending_time_prompt"
android:textSize="14sp"
android:paddingRight="10dip"
android:paddingLeft="10dip"
android:gravity="center"
android:singleLine="true"
android:maxWidth="@dimen/advanced_time_selector_edit_texts_width"
android:background="@drawable/text_field_bg"
android:inputType="datetime"
/>
注意,按鈕沒有任何文字,它是在一個TextView補充,使我們可以有它在左邊。 發生了什麼事是文本是「爬行」。
所以,我改成了這個樣子:
<RadioGroup
android:id="@+id/time_selector_radio_group"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="@id/time_selector_hours_prompt"
android:layout_below="@id/time_selector_hours_prompt"
android:layout_alignParentRight="true"
android:layout_marginRight="30dip"
android:gravity="right"
android:orientation="vertical"
android:checkedButton="@+id/time_selector_first_radio"
>
<RadioButton
android:id="@+id/time_selector_all_day_radio"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="1dip"

android:drawableRight="@drawable/radio_button_selector"

<RadioButton
android:id="@+id/time_selector_before_noon_radio"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="1dip"

</RelativeLayout>
</RelativeLayout>
</RadioGroup>
它仍然是不完美的,當然,它不承認它作爲一個RadioGroup中。
我想去擴展RadioButton的方向,但不知道如何改變佈局。
任何示例代碼,你試過了什麼? – donfede 2013-05-13 06:14:34
