Calling android dialog without it fading the background
提问by Codejoy
I have this nice dialog view I set my UserInputDialog class to:
我有一个很好的对话框视图，我将 UserInputDialog 类设置为：
<LinearLayout android:id="@+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:id="@+id/nameMessage"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="What is your name Captain?"
>
</TextView>
<EditText
android:id="@+id/nameEditText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="18sp"
>
</EditText>
<LinearLayout android:id="@+id/LinearLayout02" android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_gravity="center_horizontal">
<Button
android:id="@+id/okButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="OK">
</Button>
<Button android:id="@+id/cancelButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Cancel">
</Button>
</LinearLayout>
</LinearLayout>
I want my dialog to show up but for the background to not fade out. Is this possible? Cause the view that calls this dialog has a neato background I would like to be shown as a backdrop to the dialog.
我希望我的对话框显示出来，但背景不会淡出。这可能吗？因为调用这个对话框的视图有一个neato 背景，我想作为对话框的背景显示。
I found this online:
我在网上找到了这个：
<style name="doNotDim" parent="@android:style/Theme.Dialog">
<item name="android:backgroundDimAmount">0</item>
</style >
but not sure how to apply that to my dialog? I have a class called public class UserInputDialog extends Dialog implements OnClickListener. It sets its content view to the layout described above.
但不确定如何将其应用于我的对话框？我有一个名为public class UserInputDialog extends Dialog implements OnClickListener. 它将其内容视图设置为上述布局。
I think I am doing this all right, just not sure how to add that style so I can NOT fade the background.
我想我这样做没问题，只是不知道如何添加那种样式，所以我不能淡化背景。
Secondary question: Can you get new looks on your dialog (by say having an image or icon display with your text there) by using Themes?
次要问题：您能否通过使用主题在对话框中获得新外观（比如在那里显示带有文本的图像或图标）？
