在android中自定義progressdialog動態創建

Question

我已經在asynctask中動態創建了progressdialog。我爲我的應用使用自定義樣式。當我這樣做時，我的progressdialog風格變爲白色，我需要我的默認樣式黑色與白色文本。

我的Java文件：

class LoginTask extends AsyncTask<Void, Void, Void> { 

private final ProgressDialog dialog = new ProgressDialog(Login.this); 

@Override 
protected void onPreExecute() { 
    this.dialog.setMessage("Logging in..."); 
    this.dialog.show(); 
} 

// my prog 

@Override 
    protected void onPostExecute(Void result) { 
     if (this.dialog.isShowing()) { 
     this.dialog.dismiss(); 
     }} 

我style.xml：

<style name="AppBaseTheme" parent="android:Theme.Light"> 

</style> 

<!-- Application theme. --> 
<style name="AppTheme" parent="AppBaseTheme"> 
    <!-- All customizations that are NOT specific to a particular API-level can go here. --> 
    <item name="android:windowBackground">@drawable/blue</item> 
    <item name="android:textColor">@color/white</item> 
    <item name="android:editTextColor">@color/white</item> 
    <item name="android:buttonStyle">@android:style/Widget.Holo.Button</item> 
    <item name="android:dropDownSpinnerStyle">@android:style/Widget.Holo.Spinner</item> 
    <item name="android:textAppearanceButton">@android:style/TextAppearance.Widget.Button</item> 
    <item name="android:progressBarStyle">@style/ProgressBar</item> 

</style> 
<style name="ProgressBar" parent="@style/android:Theme.Holo"> 
    <item name="android:textColor">@color/red</item> 
    <item name="android:background">@color/green</item> 
</style>

更改下面一行的通過構造函數傳遞style ...

private final ProgressDialog dialog = new ProgressDialog(Login.this); 

到th是...

private final ProgressDialog dialog = new ProgressDialog(Login.this, R.style.ProgressBar); 

更新：

我只是改變了style如下...及其工作。

<style name="ProgressBar" parent="@style/android:Theme.Holo"> 
    <item name="android:textColor">#FFFFFF</item> 
    <item name="android:background">#000000</item> 
</style>
