的源代码，并将的所有条目替换为。 将此代码添加到项目中的某些xml文件中（通常其名称为attrs.xml）：<resources> <declare-styleable name=\"RadioGroup\"> <attr name=\"android:checkedButton\" /> </declare-styleable> </resources>public RadioGroup(Context context) { super(context); if (!isInEditMode()) { init(); } } public RadioGroup(Context context, AttributeSet attrs) { super(context, attrs); if (!isInEditMode()) { TypedArray attributes = context.obtainStyledAttributes( attrs, R.styleable.RadioGroup, 0, android.R.style.Widget_CompoundButton_RadioButton); int value = attributes.getResourceId(R.styleable.RadioGroup_checkedButton, View.NO_ID); if (value != View.NO_ID) { mCheckedId = value; } attributes.recycle(); init(); } }内部类中删除以下构造函数：public LayoutParams(int w, int h, float initWeight) { super(w, h, initWeight); }方法调用替换为方法。重要说明：在这种情况下，将无法从使用此小部件的代码中使用此方法。 还没有尝试过，但希望能成功。旗低饶彤
