Android AlertDialog全屏显示去除白色边框

使用styles.xml风格：

Style.xml代码
<style name="FullScreenDialog" parent="android:style/Theme.Dialog">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowFrame">@null</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowIsTranslucent">false</item>
    <item name="android:background">@android:color/black</item>
    <item name="android:windowBackground">@null</item>
    <item name="android:backgroundDimEnabled">false</item>
</style> 

使用AlertDialog的上层接口类：

Java代码
Dialog reNameDialog = new Dialog(getContext(), R.style.FullScreenDialog);
LayoutInflater mLayoutInflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View reNameView = mLayoutInflater.inflate(R.layout.audiorecord_rename, null);
LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
reNameDialog.addContentView(reNameView, params);
reNameDialog.show();
