改变Indeterminate Progress Bar的风格

Question

我想改变我现在拥有的东西，几乎看不到： 对此：

这是一个没有文字，标题或背景的自定义进度对话框。只有微调器。

我将此实现用于进度对话框：

public class IndeterminateProgressSpinner extends Dialog {
static Dialog dialog;

public static IndeterminateProgressSpinner show(Context context,
        OnCancelListener cancelListener) {
    dialog = new IndeterminateProgressSpinner(context);
    dialog.setTitle(null);
    dialog.setCancelable(false);
    dialog.setOnCancelListener(cancelListener);
    /* The next line will add the ProgressBar to the dialog. */
    ProgressBar pb = new ProgressBar(context);
    dialog.addContentView(pb, new LayoutParams(LayoutParams.WRAP_CONTENT,
            LayoutParams.WRAP_CONTENT));
    dialog.show();
    return (IndeterminateProgressSpinner) dialog;
}

public IndeterminateProgressSpinner(Context context) {
    super(context, R.style.indeterminateProgressSpinner);
}

这是样式R.style.indeterminateProgressSpinner

    <style name="indeterminateProgressSpinner">
    <item name="android:windowFrame">@null</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowTitleStyle">@null</item>
    <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
    <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
    <item name="android:backgroundDimEnabled">false</item>
    <item name="android:background">@android:color/transparent</item>
    <item name="android:indeterminateOnly">true</item>
    </style>

谢谢
