我需要仅与离心器和不带盒（或至少具有较小框和中间图像）创建一个progressDialog

I need to create a progressDialog only with the spinner and without the box (or at least with a smaller box and the image in the middle).

我不希望一个微调添加到我的.xml（布局文件）加载微调。

I don't want to add a spinner to my .xml (layout file) to load the spinner.

有没有办法做到这一点？谢谢！

Is there any way to accomplish this? Thanks!

推荐答案

试试这个方法：

pd = new ProgressDialog(Login.this,R.style.MyTheme);
pd.setCancelable(false);
pd.setProgressStyle(android.R.style.Widget_ProgressBar_Small);
pd.show();

而在价值创造的主题 \ styles.xml

And create Theme in values\styles.xml

 <style name="MyTheme" parent="android:Theme.Holo.Dialog">
    <item name="android:alertDialogStyle">@style/CustomAlertDialogStyle</item>
    <item name="android:windowBackground">@color/transparent</item>
    <item name="android:textColorPrimary">#FFFFFF</item>
     <item name="android:backgroundDimEnabled">false</item>
    <item name="android:textColor">#FFFFFF</item>
    <item name="android:textStyle">normal</item>
    <item name="android:textSize">12sp</item>
</style>

和也值添加此主题 \ styles.xml

And also add this Theme in values\styles.xml

 <style name="CustomAlertDialogStyle">
    <item name="android:bottomBright">@color/transparent</item>
    <item name="android:bottomDark">@color/transparent</item>
    <item name="android:bottomMedium">@color/transparent</item>
    <item name="android:centerBright">@color/transparent</item>
    <item name="android:centerDark">@color/transparent</item>
    <item name="android:centerMedium">@color/transparent</item>
    <item name="android:fullBright">@color/transparent</item>
    <item name="android:fullDark">@color/transparent</item>
    <item name="android:topBright">@color/transparent</item>
    <item name="android:topDark">@color/transparent</item>
</style>

和增加值\ colors.xml

<color name="transparent">#00000000</color>
