以编程方式将RadioButton的边距或填充添加到RadioGroup中

Question

我想以编程方式向RadioGroup添加边距或填充但不起作用。

单选按钮：

<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代码：

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

radioGroup.addView(radioButtonView);

我尝试使用LayoutParams和dividerPadding，但它不起作用

Answer 1

试试这个

CREATE OR REPLACE TRIGGER CREAT_SERVIÇO 
BEFORE INSERT ON SERVIÇO 
BEGIN
  if((SELECT MORADA_RUA FROM SERVIÇO)=NULL and (SELECT LOCAIS_ID_LOCAL FROM SERVIÇO) = NULL) = TRUE
   THEN
      RAISE_APPLICATION_ERROR(-20000, 'YOU HAVE TO HAVE AN ADRESS OR AN LOCAL');
END IF;
END;

保证金＆amp;填充RadioButton：

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的边距和填充是相同的，只有LayoutParams的类型不同（不是RadioGroup.LayoutParams），但你的RadioGroup的父布局是什么：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，下以像素为单位，因此您应将DP转换为PX，如此answer
