Android dialog custom style

问题

I have a custom theme which is applied to the activity:

<style name="Sample" parent="android:Theme">
  <item name="android:dialogTheme">@style/Sample.Dialog</item>
</style>

<style name="Sample.Dialog" parent="android:Theme.Dialog">
  <item name="android:windowBackground">@drawable/sample_background</item>
</style>

I'm creating a sample Dialog like this:

Dialog dialog = new Dialog(SampleActivity.this);
dialog.setContentView(R.layout.sample_layout);
dialog.show();

My custom dialog style isn't applied. Created dialog still has the standard background. What's wrong here?

回答1:

On initializing :

Dialog dialog = new Dialog(SampleActivity.this, R.style.Sample.Dialog);
