在android中自定义progressdialog动态创建

Question

我动态地在asynctask中创建了progressdialog.我为我的应用程序使用自定义样式.当我这样做,我的progressdialog风格改为白色我需要我的黑色默认风格与白色文本.

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();
        }}

我的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>

更改以下行以style通过您的构造函数...

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

对...

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

更新:

我只是改变style如下...并为其工作.

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