xml - 显示进度条时删除暗屏 - android

Question

我有一个带有进度条的 Asynctask。我为进度条创建了自定义布局，但是当进度条出现时屏幕变暗。我怎样才能删除这个？这是我的代码，

活动

 final ProgressDialog progDailog = new ProgressDialog(DashboardActivity.this);
            class loadComments extends AsyncTask<JSONObject, String, JSONObject> {
@Override
                protected void onPreExecute() {
                    super.onPreExecute();


                    progDailog.setIndeterminate(false);
                    progDailog.setCancelable(true);
                    progDailog.show();
                    progDailog.setContentView(R.layout.progress_circle);
                } 

                @Override
                protected void onProgressUpdate(String... values) {
                    super.onProgressUpdate(values);

                } 

                protected JSONObject doInBackground(JSONObject... params) {


                }

                @Override
                protected void onPostExecute(JSONObject json2) {
                    progDailog.dismiss();

                } 
            }


            new loadComments().execute();

进度条xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:background="#00000000">
<ProgressBar
android:indeterminateDrawable="@drawable/progress"
android:layout_height="wrap_content" android:layout_width="wrap_content"/>
</LinearLayout>

你可以用这个

样式.xml

<resources xmlns:android="http://schemas.android.com/apk/res/android">

    <style name="MyDialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowBackground">@color/orange_transparent</item>
        <item name="android:windowIsFloating">false</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowTitleStyle">@null</item>
        <item name="android:colorBackgroundCacheHint">@null</item>
        <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
        <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
        <item name="android:gravity">center</item>
    </style>

</resources>

你的 Progressbar.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#00000000"
    android:gravity="center"
    android:orientation="vertical" >

    <ProgressBar
        style="@style/MyDialog"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:indeterminateDrawable="@drawable/progress" />

</LinearLayout>
