我有DialogFragment,它显示了一些信息。它的工作很好,但我需要不同的标题,我需要白色标题颜色文本和标题的蓝色背景。 这是我的xml:

我的DialogFragment,但我认为它不会那么有用:
public class LessonDialogFragment extends DialogFragment {
View view;
String title;
public LessonDialogFragment(String title) {
this.title = title;
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
view = inflater.inflate(R.layout.detail_dialog_fragment, container, false);
getDialog().setTitle(title);
return view;
}
}
我不知道如何改变它,也许你可以帮助我。
答案 0 :(得分:0)
用于自定义布局:
https://developer.android.com/guide/topics/ui/dialogs.html#CustomLayout
AlertDialog dialog = builder.show();
// Set title divider color
int titleDividerId = getResources().getIdentifier("titleDivider", "id", "android");
View titleDivider = dialog.findViewById(titleDividerId);
if (titleDivider != null)
titleDivider.setBackgroundColor(getResources().getColor(android.R.color.holo_purple));
自定义标题的背景稍微复杂一些......您需要在主题中定义一个alertDialogStyle,定义如何绘制对话框的每个区域。例如:
<style name="Theme.Yours" parent="@android:style/Theme.Holo">
...
<item name="android:alertDialogStyle">@style/AlertDialog_Yours</item>
</style>
<style name="AlertDialog_Yours">
<item name="android:fullDark">...</item>
<item name="android:topDark">...</item>
<item name="android:centerDark">...</item>
<item name="android:bottomDark">...</item>
<item name="android:fullBright">...</item>
<item name="android:topBright">...</item>
<item name="android:centerBright">...</item>
<item name="android:bottomBright">...</item>
<item name="android:bottomMedium">...</item>
<item name="android:centerMedium">...</item>
</style>
