在进度条Android中更改大小

Question

我的ProgressDialog中的进度条大小有问题。如何在ProgressDialog中更改我的进度条的形状大小？它应该是细线（1dip），但它大于1dip。

    pd = new ProgressDialog(context, R.style.testing);
    pd.setMessage(context.getString(R.string.sr_progress_bar_message));
    pd.setCancelable(false);
    pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
    pd.setProgress(0);
    pd.show();

风格：

<style name="testing" parent="Theme.AppCompat.Dialog">
    <item name="android:alertDialogStyle">@style/CustomAlertDialogStyle</item>
    <item name="android:background">@color/color_primary</item>
</style>

<style name="CustomAlertDialogStyle1">
    <item name="android:bottomBright">@android:color/transparent</item>
    <item name="android:bottomDark">@android:color/transparent</item>
    <item name="android:bottomMedium">@android:color/transparent</item>
    <item name="android:centerBright">@android:color/transparent</item>
    <item name="android:centerDark">@android:color/transparent</item>
    <item name="android:centerMedium">@android:color/transparent</item>
    <item name="android:fullBright">@android:color/transparent</item>
    <item name="android:fullDark">@android:color/transparent</item>
    <item name="android:topBright">@android:color/transparent</item>
    <item name="android:topDark">@android:color/transparent</item>
</style>

Definiton：

pd.setProgressDrawable（context.getResources（）getDrawable（R.drawable.progress_dialog））;
