Create a progressDialog only with the spinner (in the middle)
提问by Filnik
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).
我只需要使用微调器而不使用框（或至少使用较小的框和中间的图像）创建一个 progressDialog 。
I don't want to add a spinner to my .xml (layout file) to load the spinner.
我不想在我的 .xml（布局文件）中添加微调器来加载微调器。
Is there any way to accomplish this? Thanks!
有什么办法可以做到这一点吗？谢谢！

try this way:
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();
And create Themein values\styles.xml
并在其中创建主题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>
And also add this Themein values\styles.xml
并将此主题添加到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>
And add values\colors.xml
并添加 values\colors.xml
<color name="transparent">#00000000</color>

Just single line code :
只是单行代码：
pd.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
