安卓: DialogFragment的自定义布局不像AlertDialog那样在宽度上完全显示

public class CustomDialogFragment extends DialogFragment {
    
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.dialog_layout, container, false);
        return view;
    }
    
    @Override
    public void onStart() {
        super.onStart();
        // 设置对话框宽度为匹配父容器
        if (getDialog() != null && getDialog().getWindow() != null) {
            getDialog().getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        }
    }
}

CustomDialogFragment dialogFragment = new CustomDialogFragment();
dialogFragment.show(getSupportFragmentManager(), "CustomDialog");
