以編程方式將RadioButton的邊距或填充添加到RadioGroup中

Question

我想以編程方式向RadioGroup添加邊距或填充但不起作用。

單選按鈕：

<RadioButton xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/ic_fruit"
    android:button="@null"
    android:checked="false" />

RadioGroup中：

<RadioGroup
            android:id="@+id/radio_group"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="10dp"
            android:layout_marginTop="10dp"
            android:orientation="horizontal">

</RadioGroup>

Java代碼：

RadioButton radioButtonView = (RadioButton) getActivity().getLayoutInflater().inflate(R.layout.radio_button, null);

radioGroup.addView(radioButtonView);

我試圖使用LayoutParams和dividerPadding但它不起作用

Answer 1

試試這個

  RadioButton radioButtonView = (RadioButton) getLayoutInflater().inflate(R.layout.radio_button, null, false);
  RadioGroup.LayoutParams params = new RadioGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
  params.setMargins(15, 15, 15, 15);
  radioButtonView.setLayoutParams(params);
  radioGroup.addView(radioButtonView);

Answer 2

RadioButton的邊距和填充：

RadioButton rd = new RadioButton(getActivity());
RadioGroup.LayoutParams params = new RadioGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
params.setMargins(left, top, right, bottom);
rd.setLayoutParams(params);
rd.setPadding(left, top, right, bottom);
radioGroup.addView(rd);

RadioGroup的邊距和填充是相同的，只有LayoutParams的類型不同（不是RadioGroup.LayoutParams），而是RadioGroup的父布局是：LinearLayout.LayoutParams或RelativeLayout.LayoutParams或FrameLayout.LayoutParams等。你明白了。

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
params.setMargins(left, top, right, bottom);
radioGroup.setLayoutParams(params);

左，上，右，下以像素為單位，因此您應該將DP轉換為PX，就像在這個答案中一樣
