Style DialogFragment in Android: Quick Guide

To customize the style of a DialogFragment, you can follow these steps:

1. Create a custom style resource file, such as “dialog_style.xml”, and define the desired style properties within it. For instance, you could set the background color, text color, border, and so on for the dialog. Here is an example:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="CustomDialogStyle" parent="Theme.AppCompat.Light.Dialog">
        <item name="android:background">@android:color/white</item>
        <item name="android:textColor">@android:color/black</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <!-- 其他样式属性 -->
    </style>
</resources>

1. Create a view on the screen.

public class MyDialogFragment extends DialogFragment {

    @NonNull
    @Override
    public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        return dialog;
    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_my_dialog, container, false);
        // 设置自定义样式
        int style = R.style.CustomDialogStyle;
        setStyle(DialogFragment.STYLE_NORMAL, style);
        return view;
    }
}

The method setStyle(DialogFragment.STYLE_NORMAL, style) in the above code is used to set a custom style for the DialogFragment.

1. In your Activity or Fragment, create and display a DialogFragment. For example:

MyDialogFragment dialogFragment = new MyDialogFragment();
dialogFragment.show(getSupportFragmentManager(), "dialog_fragment_tag");

To display a DialogFragment, call the show() method and pass the FragmentManager and a tag as arguments.

This way, you can set and use custom DialogFragment styles. Remember to define the interface elements (such as buttons, text boxes, etc.) and layout of the dialog in the layout file.
