我正在动态生成RadioButtons

RadioButton radioButton=new RadioButton(context);  

LayoutParams layoutParams=new LayoutParams(radioWidth,radioHeight);
layoutParams.gravity=Gravity.CENTER;

radioButton.setLayoutParams(layoutParams);
radioButton.setGravity(Gravity.CENTER);

BitmapDrawable bitmap = ((BitmapDrawable)drawableResource);
bitmap.setGravity(Gravity.CENTER);

radioButton.setBackgroundDrawable(getResources().getDrawable(R.drawable.itabs_radio));
radioButton.setButtonDrawable(bitmap);

你可以看到我拼命想把按钮的重力设置为中心,但没有理由它总是居中和左对齐,继承人的原因 - 安卓单选按钮的默认样式:

<style name="Widget.CompoundButton">
<item name="android:focusable">true</item> 
<item name="android:clickable">true</item>
<item name="android:textAppearance">?android:attr/textAppearance</item> 
<item name="android:textColor">?android:attr/textColorPrimaryDisableOnly</item> 
<item name="android:gravity">center_vertical|left</item> 
</style>

<style name="Widget.CompoundButton.RadioButton">
<item name="android:background">@android:drawable/btn_radio_label_background</item> 
<item name="android:button">@android:drawable/btn_radio</item> 
</style>

有什么方法可以将按钮对齐到中心吗？
